  • Hot-rolled - Floor plate (US Standard units)

    Durbar® is hot-rolled structural steel floor plate which can reduce construction costs.

    Durbar®’s distinctive, raised surface pattern is extremely slip-resistant at all angles – allowing plates to be used in any direction. Its self-draining surface is easy to clean and reduces corrosion.

    Ympress® for weight savings and component strength

    Ympress® is Tata Steel’s hot-rolled HSLA product. It is highly formable and delivers weight savings and increased component strength. The result is lighter, stronger, more consistent products.

    Ympress® adds value to automotive, lifting and excavating and shipbuilding applications, among others.

    Overview

    Durbar is hot-rolled structural steel floor plate offering distinct benefits. It combines structural integrity with appealing features designed for easy use and long life. Durbar helps reduce construction costs by eliminating the need for separate structural and flooring components. Its distinctive, raised surface pattern is extremely slip resistant at all angles – allowing plates to be used in any direction. The raised pattern creates a self-draining surface. This is easy to clean and reduces corrosion for extended product life.

    Applications

    • Bridges
    • Cladding and protective barriers
    • Commercial vehicles
    • Containers
    • Lifts
    • Offshore installations
    • Shipbuilding
