types of coils

Steel coils are a fundamental component in various industrial applications due to their versatility and durability. This page offers a brief education on the types of steel coils we accept and highlights some of their main uses.

Hot Rolled

Hot roll coil is steel that has been heated above its recrystallization temperature and rolled into a coil. This process makes it easier to form and shape the steel, but the surface finish is typically rough.

Common Applications

Automotive Parts
Heavy Machinery

Hot Rolled Pickled and Oiled

Hot roll pickled and oiled (HRPO) coil is hot roll coil that has undergone a pickling process to remove scale and then coated with oil to prevent rusting. This results in a cleaner surface and improved corrosion resistance.

Common Applications

Automotive Frames
Pipe and Tubing
Industrial Equipment

Cold Rolled

Cold rolled coil is produced by further processing hot roll coils at room temperature, resulting in a smoother surface and tighter tolerances. This steel is harder and has better surface finish and dimensional accuracy.

Common Applications

Electrical Panels

Floor Plate

Floor plate, also known as diamond plate, is steel that features a raised pattern of lines or lozenges on one side, enhancing its traction properties. This makes it ideal for applications requiring slip resistance.

Common Applications

Industrial Flooring
Stairs and Walkways
Truck Beds and Ramps
Galvannealed coil is steel that has been hot-dip galvanized and then annealed. This process provides a zinc-iron alloy coating that is more easily painted and has better weldability compared to regular galvanized steel.

Common Applications

Automotive Body Panels
Electrical Boxes
Exterior Construction


Galvanized coil is steel coated with a layer of zinc to protect it from corrosion. This coating extends the steel’s lifespan and provides resistance to rust.

Common Applications

Roofing and Siding
Automotive Body Parts
HVAC ductwork
