Steel Plates and Sheet Coils

The steel plates and sheet coils that CamaSteel sources are all under the category of sheet metal. This fundamental form of steel can be cut and bent into a variety of shapes. CamaSteel offers these products in their steel plate and sheet coil form which are both highly applicable to many different industries. Metal sheets have been used for generations for architectural purposes and are often offered in many different metals and grades including stainless steel, the most popular, and brass.

Sheet metal can be used in automobiles and truck bodies, airplane wings, medical tables, building roofs and many other commercial and industrial applications. This steel is thin and pliable but maintains its structural integrity and strength unlike steel foils. This characteristic allows sheet metal to be utilized under heavy use.

Checkered Steel Plate

Checkered steel plates, or diamond plates, are textured steel plates that reduce the risk of slipping. This is done by producing a diamond plate as a solution for stairs, catwalks, walkways, and ramps in industrial areas. It is also used in vehicles to prevent slipping on the metal which otherwise would be slippery, especially in wet situations. These steel plates with concave and convex surface patterns on the surface is most prominent in transportation, construction, decoration, equipment, flooring, machinery, shipbuilding, and other industries. They are produced using a technique where the surface pattern is hot rolled onto the steel plate.

Cold Rolled Steel Plates

Cold rolled steel plates are known for its outstanding properties which include easy formability, smooth and clean surface, and application in automobiles, furniture, appliances, and other commercial and industrial applications. Cold rolling essentially is steel that is pressed with a pressurized roller at room temperature. Cold rolled steel commonly has an increase in strength, nearly 20%, compared to hot rolled steel through its use of strain hardening. This process includes breakdowns, semi-finishing- sizing, semi-roughing, roughing, and the resulting finishing that helps form cold rolled steel shapes. Because of the complexity and precision offered by cold rolled steel, these are typically used for more precise smaller parts, and for parts that require extra durability. 

Hot Rolled Steel Plates

Hot rolled steel plates are steel plates that undergo a pressure rolling procedure that heats the steel typically above the steel’s recrystallization temperature allowing the steel to be shaped and formed more easily. This allows the steel to be made into much larger sizes. This steel is then cooled at room temperature which eliminates future stress on the material under more strenuous uses. Hot rolled steel plates shrink non-uniformly when they cool leading to less uniform sizes, although the steel mills still ensure that the margin of size is within this area. Hot rolled steel plates are typically cheaper than cold rolled steel which undergoes a much longer process and quality check than hot rolled steel. The surface of hot rolled steel is typically scaly and can be removed through pickling, grinding, or sandblasting. 

Cold Rolled and Hot Rolled Sheet Coils

Hot rolled coil is hot rolled steel that is already rolled and annealed. This is then wound into a roll. This hot rolled coil is recrystallized under high temperatures and shaped and formed to specification. It is later cooled and wound into a roll. However, cold rolled sheet coil undergoes a process where the hot rolled sheet has rust removed by being pickled through a weak acid solution, washed, brushed, dried, oiled and unrolled into its sheet form. After this process, the steel sheet is cold rolled under pressure and wound up into a roll. Cold rolled sheet coil has a much higher finish, smoother surface, greater dimensional accuracy, and strength than hot rolled coils. A majority of cold rolled steel is processed for automotive use.
