  • 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 are U-Beams Manufactured?

    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.

    U Beams, if exported, are usually transported by Sea. When exported, packing and labeling are reviewed for breakage, security, excess weight, and proper identification markings. Export license is also required.

    Where to Buy U-Beams?

    transport of U Beam secured

    You may be able to find U-Beams in small quantities in your area. But if you want to buy large quantities of U-Beams, it is preferable to import directly from the manufacturers. They can issue certifications and provide cost savings which is better than buying the steel in small quantities locally or from a distributor.

  • How to Buy Steel Wire Rod

    What is steel wire rod?

    • Steel wire rods are almost identical to GI or galvanized iron wires.
    • They look exactly the same but are made from different materials and the way each is manufactured also varies.
    • Steel wire rods are made from billets

    How is steel wire rod manufactured?

    • Billets are what can be considered as semi-finished metal pieces. They need to be processed further to become valued products.
    • Billets usually come in the form of square, circle, or rectangle which has areas below 36 sq. inches. Wire rods are produced using the process called extrusion. The billets are pushed through a die where they are molded into whatever the shape of the die opening is.
    • The dies, which can be circular, rectangular, or square-shaped, have a usual diameter from 5 – 42 millimeters.
    • The billets are not pre-heated before going through the dies but are heated as they are passing within the molds.
    • At the end of 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 winded wire rods are still hot, they are cooled using either air or 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?

    • 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:

    GRADE DIAMETER (Φ) Q195 5.5 mm – 16 mm Q215 5.5 mm – 16 mm Q235 5.5 mm – 16 mm 1006B 5.5 mm – 16 mm 1008B 5.5 mm – 16 mm 1012B 5.5 mm – 16 mm 1017B 5.5 mm – 16 mm 1018B 5.5 mm – 16 mm

    What are the Chemical Composition and Mechanical Properties of typical steel wire rod?

    A typical steel wire rod has a chemical composition of the following:

    • Carbon
    • Manganese
    • Silicon
    • Phosphorous
    • Sulfur
    • Boron

    Its mechanical properties are as follows:

    GRADEYield StrengthTensile Strength

    SAE1006≥210 210 - 370 Mpa
    SAE1008≥195315 - 430Mpa

    What are the main applications of steel wire rod?

    • Steel wire rods have many potential applications, mainly wire drawing, construction uses, and tools manufacturing.
    • GI or galvanized iron wires are actually made from steel wire rods which have been coated by zinc in order to prevent it from corrosion and rusting.
    • Steel wire rods are also used to manufacture nails and other construction materials.

  • 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.

     

    • 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.

    • 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 are 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.

    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 in 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.

    What are the Chemical Composition and Mechanical Properties of typical rebar?

    • The different types of rebar basically have the same chemical composition.
    • They consist of manganese, silicon, alloy, carbon, and many more.
    • Some type of rebar is coated with outer protection like epoxy and stainless steel.
    • Common mechanical properties of rebar are as follows:

    GRADE Yield Strength Tensile Strength Elongation
    40 ≥280 Mpa 500 Mpa 20 %
    60 ≥420 Mpa 620 Mpa 20 %

    What are the main applications of rebar?

    • Rebar is generally used in the field of construction to reinforceconcrete structures like slabs and foundations.
    • Rebar increases the concrete’s tensile strength so that it can withstand prolonged exposure to tension and compression forces.
    • Practically every major modern construction site uses rebar for construction. You can think of rebar as the actual mold of the structures.
