    What is Steel?

    Iron core

    Steel is made from iron ore. Iron ores are rock and minerals from which metallic iron can be extracted. Steel was first discovered and produced in India by using a method that bonds the right amount of carbon and iron.

    Typical steel specifications

    Specifications include steel properties such as hardness, toughness, tensile strength, yield strength, corrosion, and more.

    1. Specific heat of steel – the specific heat capacity of steel is 420 J/(kg C). This can be important in the production of steel.
    2. Specific weight of steel – the specific weight of steel is about 7.8 – 7.9 kg/dm3. It is important to know the weight of the steel product being purchased. This can ensure safety and support of the steel product in its structure.
    3. Specific gravity of steel – Steel has a specific gravity of 7850 kg/dm3.
    4. Strength of steel – Tensile strength refers to measurement of force required to break the material. Yield strength refers to the measurement of force required to start bending or deforming the material.

    Advantages of Steel

    • Speed of Construction
    • Cost Savings
    • Attractive Design
    • High Strength and Durability
    • Sustainable
    • Effective and Reliable

    How is Steel Made

    Steel is typically made by either using a blast furnace or an electric arc furnace. The blast furnace uses coal, ground up into a powder. The coal is cooked and turned into “coke”. The coke is then used to melt the iron ore. The electric arc furnace is a newer process. This way uses an electrical current to melt scrap steel and produce molten steel.

    Steel mill

    steel rolling mill

    Steel mills are an industrial plant for the purpose of manufacturing steel. There are various types of steel mills such as

    • Integrated steel mill
    • Specialty steel mill
    • Iron ore steel mill
    • Iron and steel scrap
    • Coke

    Is Steel Environmentally friendly?

    It is important to make sure that the environment is not negatively affected by production. At Camasteel, we strive to ensure that production follows all regulations for environmental safety. We strongly promote environmentally friendly steel production.

    Steel is a recyclable product and there has been confirmation of waste reduction in steel construction. This is mainly because steel products are tailored to the fit of a specific structure during a job. Therefore, there will be little waste of steel products if done correctly.

    electric arc furnace

    However, having eco-friendly production also depends on the technology. Blast furnace can be very polluting by dissolving carbon into iron or steel. Some modern technology, though, such as Electric Arc Furnace (EAF) have reduced polluting. Using EAF reduces carbon foot printing and is becoming more and more popular in the production of steel. Many companies are seeking a “go green” route with all of their systems.

    Overview of Steel Products

    Raw steel vs finished products of steel

    Raw steel is a product that is un-coated. This is more likely to rust. Finished products have coating on them for more protection and a cleaner look. Clear coat is a finish that still has the industrial look, but is protected by the coat that will last a very long time. Lastly, there is a zinc coat. This gives the steel a brighter and cleaner silver finish. This coating is sustainable for outdoor use.

    Popular steel products

    The most popular steel products being sold include

    • Structural Beams and Bars

    I beam
    • Piping and Tubing

    Seamless pipe

    Hot rolled steel plate

    Here at Camasteel, we are committed to helping our clients worldwide buy steel and hence are constantly updating relevant informative posts such as:

    Steel Prices

    Price of steel

    Steel prices have fluctuated over the years, but because of inflation have ultimately been increasing. The price of steel can change day by day and more drastic changes can occur in this market if there are natural disasters or demand changes.

    Global Steel Market

    Pricing of scrap steel have fluctuated. In early 2021 prices were around:

    • Copper wire = $2.66/lb
    • #1 Copper tubing = $2.50/lb
    • #2 Copper tubing = $2.35/lb
    • Insulated copper wire = $0.70/lb
    • Steel BX = $0.21/lb
    • Brass = $1.41/lb
    • Brass shells = $1.24/lb
    • Stainless steel = $0.32/lb
    • Light iron = $110/ton
    • #1 Steel = $177/ton
    • Cast iron = $183/ton
    • Shreddable steel = $166/ton

    Trading of Steel

    Primary Financial Instruments for Trading Steel:

    1. Over the counter (OTC) – this involves a private contract between the trader and the client, but not in the same format of a standard contract. This offers traders an opportunity to use options and swap products in their trading. Since this is a private contract, it involves more risk than other contract options. An OTC can be made for an agreed upon grade or quantity of steel, but some other specifications may require a futures contract.
    2. Futures Contracts – steel can be traded on the Exchange. There is a contract that is a cash-settled contract. Each contract can account for a certain amount of steel in metric tons. The price of the contract is settled between the two parties based on the difference between the purchase price and the sales price.
    3. Steel ETFs – similar to the stock market, shares can be traded on exchanged for companies that produce steel.
    4. Contract for difference (CFD) – this allows speculation on prices of shares from steel producing companies. The value of a CFD is the difference between the price of the shares when purchased and current price. CFDs are also very risky.

    Steel regulation

    Regulations on buying steel

    Most regulations are put in place when companies are importing their steel. Typically, an import license is required to import steel and an export license is required when exporting steel. The specifics may differ for each country.

    Safety regulations in the steel industry

    grinding balls tested

    Before transporting the product, it is important that the steel is inspected and tested for quality assurance. There are different types of tests depending on the product. Products may be tested for

    • Hardness
    • Tension
    • Impact
    • Corrosion and wear resistance
    • Strength

    China Steel Industry

    China’s steel industry is growing more rapidly than most other countries and is now the largest contributor to the production of steel in the world. In the 1900s, the Chinese steel industry was very small. After the wars, China was behind compared to other countries productions. It wasn’t until the late 1900s that they had a rapid growth in their economy and their steel industry increased its output. It has continued to grow since.

    steel bundle import

    How much steel is imported from China?

    China is the world’s largest steel exporter. They export to over 200 countries/territories. In the last year, China has exported over 62 million metric tons of steel products.

    What factors caused China to expand the industrial production of iron and steel?

    This industry first expanded because of the demand in agriculture for the use of tools, in addition to the demand for weapons, buildings, and bridges. As time passed, the demand for iron and steel grew and China created the capacity for more steel production.

    Quality of Chinese steel

    China is currently working hard to make sure all of the steel they produced is of high quality. It is important for these Chinese companies to focus both on quality and quantity, not just quantity and price competition. This may result in capacity limits for steel producing companies.

    How to Buy Steel from China

    Steel Transport: Importing from China

    steel import containers

    Steel is typically transported by loading a truck using equipment that is safe for carrying heavy bundles of steel. It is secured properly before being shipped to its destination or a port to be shipped overseas for export.

    The most common ways to ship steel are:

    • Rail
    • Truck
    • Ship

    In different size bundles/containers such as:

    TypeFor what product?
    20 ft containersMost steel products, in bundles, can be shipped in this container
    40 ft containersLarger quantity of most bundles of steel
    Large polypropylene bagsGrinding media steel balls or other small steel products
    200-liter drum barrelsGrinding media steel balls or other small steel products

The size of grinding balls can be a diameter between 20mm and 150mm, or 1 inch to 6 inch. The size of grinding rods can come in diameter between 40mm and 120mm. Forged steel grinding balls don’t lose shape or crack easily. They are durable and have great resistance.

    What is Grinding Media Used For?

    The industries that typically use Grinding Media are the mining and construction industries. Grinding Balls are used in ball mills. They are useful when breaking down and grinding materials such as rocks, cement, and others.

    Some markets that use grinding media include:

    • Mineral processing
    • Construction sector
    • Road construction
    • Ore crushing
    • Manufacturing process

    How to Determine Suitable Grinding Media

    steel grinding rod

    Grinding media has recommended characteristics, involving the shape, size, and composition. Steel grinding balls characteristics should include:

    Shape – The shape of grinding media is typically a sphere. This form is highly dense and does not chip easily. There are two shapes of grinding media that are most efficient. These include the ball shape and the cylinder rod.

    Diameter – The grinding ball should have a smaller diameter, but still large enough to get the best results. It can be more accurate when breaking down other material. The size of forged steel grinding balls will generally range from ¾ inch to 5 inches in diameter. The size of grinding rods will generally be between 1.5 to 4 inch in diameter. Also, the length should be a few inches shorter than the mill length. The size needed for each job may vary.

    Composition – The grinding material needs to be able to withhold high grinding methods and not wear or chip quickly. The grinding material should have a greater density than the material that is being ground. The material of the grinding media may vary, as well. Camasteel sells forged steel grinding balls, cast iron grinding ball, and steel grinding rods.

    steel grinding ball in process

    How to Manufacture Steel Balls?

    steel ball manufactured form ball shape

    Camasteel uses a forging and stamping method to heat the metal to 1050 degrees Celsius. Then, it can be molded into the sphere shape. Between the forged steel grinding ball and the cast iron grinding ball, forged steel has better mechanical performance. The forged steel grinding ball must use the super wear resistant material to ensure its durability.

    When making the steel ball

    1. Heading: short lengths of wire are cut and then it is shaped into the form of a sphere.
    2. Deflashing: the ball rolls between two very heavy plates, typically cast iron plates, and becomes formed.
    3. Soft grinding: this is similar to the deflashing step, but a grinding stone is used to make the more precise form.
    4. Hot treating: the steel balls are put through heat and hardened.
    5. Descaling: removing any undesired residue from the ball.
    6. Hard grinding: this step helps with providing the perfect size and shape for the order.
    7. Finishing: giving the balls a smooth finish and coating to ensure that the product will last long.

    Which Countries Manufacture Steel Balls in Bulk?

  • What are U Beams and How to Buy U Beams

    What is a U Beam?

    hot rolled U Beam used in Construction Industry

    U Beam is a type of steel beam, which is a structural steel product with multiple uses mainly in the construction sector. U-Beams are also known as a parallel flange channel or C Beams. They typically can be welded together to form I-Beams. U Beams have a flat side with two smaller plates welded to it forming that U shape and the long flat side is typically mounted to a wall or flat surface to give support. U Beams are going to be more effective and stronger when placed vertically, but it still can be useful and strong when placed horizontally depending on the load.

    What is a U Beam Used For?

    steel structure with beam support

    U Beams are often used in construction and structural industries; they are often used in the process of building and give structure.

    U Beams can be used in just about any place that needs heavy weight support. Some of the major uses for U-Beams are:

    • Columns for support: typically mounted to another flat surface.
    • Lintels above doors
    • Beam supporting floor joists
    • Supporting main framework, walls, and roofs
    • Window and door frames
    • Automobiles
    • Manufacturing of machinery

    What is the Typical U-Beam Strength?

    Beam cross section building with U Beams

    Having the correct beam shape beam is important in having the right strength of the beams and overall structure. They are primarily placed vertically for maximum strength and support, but are also used horizontally in cross members. The U Beam is not always the best for long spans, as it is not supported as well, but it is for cross members.

    Shape of the beam

    The U Beam is also not the strongest beam shape. For example, compared to the I Beam, the U Beam is essentially half the I Beam strength, therefore it will not support as much weight. However, the U Beam can be useful depending on the needs of the project and how much weight needs to be supported.

    How to Manufacture U-Beams?

    electric arc furnace manufacture steel beams

    In factories, U-Beams are made by forcing metal through hot rollers to flatten it and then mold it into the shape of a U. There are two horizontal pieces, known as flanges, that are connected to a larger vertical piece, known as the web. These pieces are produced in the steel mill and then electric arc furnaces are used. This structural steel can either be hot-rolled or cold-rolled.

    Which Countries Manufacture Steel U-Beams?

    steel factory production line

    The main producers of Steel U-Beams are

    • China
    • United States
    • Italy
    • Japan
    • South Korea
    • Russia

    These countries have been able to create the capacity and expand their productions to produce larger quantities of steel, especially China. China’s steel imports are about 4% of all steel which shows that most of their steel comes from internal production at over 15 million metric tons. China produces about 49% of the 1.7 billion metric tons of steel produced worldwide each year and exports most of it.

    How to transport U Beams?

    U Beam steel channel U Beam shipment

    Large quantities of U Beams need cargo haulers that can handle heavy loads of steel in order to transfer them to different locations. When transporting steel beams, it is important to secure the beams to the hauler, and each other, so they do not shift and slide and make sure the weight is distributed evenly.

    Seamless steel pipes are typically exported by sea but can be transported in bundles by truck to job sites. A checking process occurs before the good is ready for export. In this process, a few things must be reviewed during packing and labeling. This may include breakage, security, excess weight, and proper identification markings. Another typical requirement for exporting is an export license.

  • How to Buy Steel Wire Rod

    What is steel wire rod?

    Steel Wire Rod is a long piece of steel that is hot rolled and when cooled, it gets wound into a coil. There are different types of shapes such as round, square, semicircle, and hexagonal.

    • Steel wire rods are almost identical to GI or galvanized iron wires.
    • They look very similar, but different materials form steel wire rods than galvanized iron. Also, the manufacturing of each varies.
    • Billets function as a steel to produce steel wire rods.

    How to Manufacture steel wire rod?

    Billets are considered semi-finished metal pieces. When processed further, the semi-finished pieces become valued products. There are many steps in the process of manufacturing steel wire rod including:

    steel wire rod in production
    • Billets usually come in the form of a square, circle, or rectangle which has areas below 36 sq. inches. A process called extrusion is how wire rods are produced. The billets push through a die. Then, the billets mold into the shape of the die opening.
    • The dies, which can be circular, rectangular, or square-shaped, have a typical diameter from 5 – 42 millimeters.
    • The billets are not pre-heated before going through the dies but heated as they pass within the molds.
    • At the end of the extrusion process, the semi-finished wire rods then go through a specialized winder which winds the wire rods into loose coil stacks.
    • Since the freshly wound wire rods are still hot, they are cooled using either air or a forced cooling process. The forced cooling process makes use of large fans, while the other one uses the surrounding air without the use of any cooling machine.
    • The wire rods are glowing red hot after the whole extrusion and winding process which is why accelerated cooling is more preferred, or else a lengthy amount of cooling time will be required.

    What are the main specifications for steel wire rods?

    various grade steel wire at Camasteel
    • Wire rods are produced with different grades. These grades each have their own specifications and corresponding applications. These specifications help the end-user or other manufacturers in choosing which grade of wire rods to purchase.
    • For an SAE 1008 wire rod, grades include Q195, Q215, Q235, 1006B, 1008B, 1012B, 1017B, and 1018B. The Q195, Q215, Q235 grades are used primarily in the field of construction and drawing wires.
    • The diameter sizes of each grade are as follows:

    GRADEDIAMETER (Φ)
    Q1955.5 mm - 16 mm
    Q2155.5 mm - 16 mm

  • How to Buy Rebar

    What is a rebar?

    • Rebar, which stands for reinforcing bar, is also known to the general public as reinforcing steel.
    • Rebar is typically what you will mostly see on establishments and buildings which as being constructed.
    • These are steel-type rods which are used to generally reinforce the foundations of a structure. It is found in any construction which uses concrete as its base foundations since rebar strengthens it.
    • Rebar acts as the bonding agent that helps keep the concrete foundations from crumbling under large stresses and loads.

    typical hot rolled rebar at Camasteel

    How is rebar manufactured?

    • The production process of rebar is very simple and requires extreme heat.
    • To make these, steel is heated down until melted and then pushed into circular openings of a certain diameter.
    • One of the distinguishing factors of rebar is that it has a “rib” design.
    • This adds to the bonding strength of the concrete and prevents it from slipping out of place.

    What materials are used in the manufacture of rebar?

    • Carbon steel is commonly the material used when making rebar.
    • Although, there are also rebar made from stainless steel, carbon fiber, glass fiber, or sometime basalt fiber.
    • Since rebar is a type of unfinished steel, it has the tendency to corrode and rust. Because of this some manufacturers of rebar coat them with epoxy or stainless steel.

    What are the common types of rebar for sale?

    Epoxy coated Rebar – This type is expensive and is usually used within foundations that are submerged in water, particularly saltwater. The epoxy coating protects it from any corrosion or rusting.

    Carbon Steel Rebar – This is considered the cheapest and affordable type of rebar. In terms of strength, it is up to par but since it has no protective coating, it is subjected to corrosion and rusting. Regardless of this, it is still the most commonly used in any type of construction.

    Stainless Steel Rebar–This type is used alternatively from carbon steel. Since it is stainless, it is automatically immune to rust and corrosion although they are more expensive than the epoxy-coated type.

    carbon reinforcing steel rebar

    What are the main specifications of rebar?

    • As with other construction materials used, rebar is classified into grades and sizes.
    • Rebar is available for sale in various diameters and lengths depending on the application
    • The steel type of rebar is required and has the same coefficient of thermal expansion as that of the concrete it is used with.
    • This is a very important specification that needs to be taken into account when choosing the right type of rebar. If the coefficient is different, they rebar, and concrete will expand at a different rate, which is highly dangerous and prone to the cracking of the concrete.
    • Rebar is commonly made with diameters from 6 mm to 57 mm
