Cold-rolled coils are essentially steel products made by cutting sheet-by-sheet plastic deformation of hot-rolled steel on cold-rolling mills. The main features of cold-rolled coils include accurate dimensional tolerances, enhanced mechanical properties, and better surface quality than hot-rolled sheets. Cold rolling also makes it possible to...
Galvanized coils feature high resistance due to the zinc coating that adheres to their top layer. As it prevents corrosion of metal under the influence of external factors without additional processing, it can be used in any climate and often last up to 50 years....
Hot rolled steel products are classified into hot-rolled coils produced through hot rolling and hot rolled steel plates made by cutting hot rolled coils. The process of manufacturing hot-rolled coils involves a continuous casting system where the slabs are rolled, cooled, and coiled into the...
Electro-galvanized sheets are made by electroplating a pure zinc coating on one or both sides of carbon steel sheets. The resultant product has an exceptionally uniform thickness, in addition to the smooth and matte appearance, similar to the cold-rolled sheet. The surface quality makes it...
Galvanneal coils are manufactured by passing cold-rolled products through a molten bath of iron-zinc alloy that gives it a fine greyish matte finish. Perhaps, the primary advantage of galvanneal coils is that the galvanneal doesn’t flake off its galvanized coating when formed, stamped, or bent....
Pre-painted steel coils are manufactured through a continuous coil coating process that comprises cleaning, pre-treating, painting, and curing. Generally, the coils are painted with two-coat paint systems—first goes the primer, then a color coating is applied on the side meant for exterior exposure, whereas the...
Stain coils are covered with a galvanized coating that prevents metal oxidations. Hence, they are primarily used in the automotive industry and for external applications as they can resist corrosion up to 30 percent longer than cold-rolled steel. Furthermore, the coating permanently adheres to the...
Slit coils are manufactured through a process called coil slitting. It involves a coil slitting line that cuts a master coil of metal into several narrower coils as it runs through a set of slitting knives. The continuous process is very precise, and it is,...
Tins coils are manufactured by winding wires around a core to create a wrapped helix pattern. They find their application in most electrical devices. Hence, at SteelPack, we produce high-purity uniform tin coils that feature the highest possible density for use in semiconductor, Physical Vapor...
