YOUR FIRST CHOICE FOR STEEL


Steel Coil & Steel Slit Strip


Steel coil is a finished steel product such as a sheet or strip which has been wound or coiled after rolling. NJR Steel branches stock a broad range of cold-rolled, galvanized and hot-rolled sheets and plates which have been cut from coils. 


These sheets and plates can then be slit into multiple narrower widths used to fabricate flat bar, tubing and lip channel, or be cut to custom lengths to suit fabricators’ and engineers’ specific requirements.


Hot-rolled coil is produced from semi-finished products that are reduced to certain thicknesses by rolling and annealing and then wound into a roll. Hot-rolled steel is used for the manufacture of pipes, steel doors and tanks, or is further processed into cold-rolled steel.


Cold-rolled sheet in coil form is produced by removing rust from a hot-rolled sheet by "pickling" it in a weak acid solution, then washing, brushing, drying, oiling and unrolling the sheet and finally performing cold-rolling by passing the sheet through a reducing mill under pressure and winding it into a roll. 


Cold-rolled steel is a more highly finished product and has a smoother surface, greater dimensional accuracy (thickness, width, length) and greater strength. Much of cold-rolled steel is processed in the automotive industry, but some are also used in the manufacture of household goods.

Steel Plate


NJR Steel supplies a comprehensive range of steel plate products.


These include:

  • Mild steel plate - used for general engineering applications
  • S355 graded steel plate - used for construction, engineering and manufacturing
  • Boiler plate - used for the manufacture of boilers and pressure vessels
  • Corten plate - which is preferred for applications that require a raised resistance to atmospheric corrosion
  • Lloyds plate - typically used for marine engineering
  • Hardwearing plate - used in heavy-duty industries such as quarrying a construction
  • Vastrap and chequer plate - used for non-slip walkways given their patterned surface
  • In-house manufactured base plates - used as a basis for vertical structural members
