  • Annealing is defined as the heating of a steel product to a suitable temperature known as the austenite phase. Once the steel section has reached this temperature it is then cooled down slowly in a closed /controlled environment. Steel Tubes can be annealed for the following reasons: • To reduce hardness and brittleness • To soften the steel for improved machinability or formability• To reduce int...

  • Galvanising is the process in which corrosion protection is provided to steel product by coating it in zinc. This can be achieved either through a hot dip process, or electrolytic. In the former, a cold reduced product passes through a series of heat treatments in which it is annealed and the surface is cleaned prior to the strip being passed continuously into a bath of molten zinc at 440°C.The co...

  • Electro-galvanized steel refers to applying a zinc coat deposited onto the steel using electrodeposition. Electro-galvanized steel has the advantage that the coating thickness can be controlled independently on the in- and outside parts. The thickness of the coating applied through electro galvanization is precise.

  • Pre-galvanized steel refers to steel which was galvanized while in sheet format, thus prior to further manufacturing. Pre-galvanization is also known as mill galvanized, due to the fact that the steel sheet is rolled through molten zinc. After the sheet is sent through the mill to be galvanized it is cut to size and recoiled. A specific thickness is applied to the entire sheet, for example pre-gal...
