Hot rolled steel coils are made from semi-finished products and are rolled, annealed, and reduced to a certain thickness before being wound into coils.
Cold rolled steel coils are made by 'pickling' hot rolled plate in a weak acid solution to remove rust, and involve cleaning, brushing, drying, oiling, uncoiling, and cold rolling.
Carbon coils are made from carbon, along with small quantities of silicon, manganese, sulfur and phosphorus, and are used for second grade applications.
Finally, galvanised coils are made by hot-dipping or electrolytic deposition of hot or cold rolled sheet in zinc, and help resist corrosion.
There are a wide range of applications for stainless steel coils, including in the medical, aerospace, automotive, construction, consumer products, electronics, and oil and gas industries. Stainless steel is divided into several categories and each category is further divided into grades and series, with 304 and 304L stainless steel coils being the most popular and economical grades.
