Galvanised coil

It is the process of applying a protective zinc coating to steel to prevent rusting. The most common method is hot-dip galvanising, in which parts are submerged in a bath of molten zinc.

Electrogalvanised coil

Electrogalvanised steel sheet consists of a cold rolled steel substrate coated with zinc by electrolytic deposition on a continuous line. The electrogalvanising process allows accurate control of the thickness of the zinc coating.

Cold rolled coil

Cold rolled sheet is produced by processing hot rolled strip through a cold rolling process followed by annealing and/or temper rolling. This process will produce steel with thinner gauges, closer dimensional tolerances and a wider range of uncoated surface finishes.

Hot rolled Steel

Hot rolled plate

Hot rolled plate is manufactured in a wide range of sizes for applications in several industries varying from construction, pressure vessel and wear resistant applications. 
Steel sheet piling, also manufactured from Hot rolled plate are used worldwide in the construction of quays walls and breakwater in harbors, locks and for bank reinforcement on rivers and canals. Other applications include temporary cofferdams in land or in water, permanent bridge abutments, retaining walls for underpasses or underground car parks and impervious containment walls.

Hot rolled coil

It is a mill process which involves rolling the steel at a high temperature, which is above the steel’s recrystallisation temperature.

Pickled & Oiled coil is hot rolled material that has been descaled of oxide film by both mechanical and chemical methods and then oiled to help retard corrosion during storage and after descaling.
