  • A finished steel product such as or strip which has been wound or coiled after rolling. A flat rolled product over 12 inches in width and of less thickness than plate.

    Hot rolled sheets are produced at elevated temperatures on rolling mills and generates a material that is resistant to work hardening and exhibits reduced levels of deformation residual stress.  Material rolled in the hot rolled condition can require more extensive leveling practices, such as temper passing or stretcher leveling downstream to eliminate coil memory.  In addition, hot-rolling may leave surface imperfections such as scale or pits which require additional finishing for a smooth surface.

    Products manufactured using hot rolled sheet include structural parts such as I-beams and H-beams, rails, stampings, automotive and equipment components.

    SS400  Steel Coil are used in Construction of Bridges, Highway Construction and Other Engineering construction.

    Hot Rolled Steel Coil  are mainly used in Construction of Bridges, Highway Construction and Other Engineering construction.

    Common uses of A 36: Shim plates, Gusset plates, bridge plates, bearing plates, robot bases, column base plates, press parallels, press platens, tooling plates, machine plates, machine frames and pedestals, steel table tops, base plates, mold & die, machine mounting plates, etc.
