PRODUCT DESCRIPTION Steel coils, also known as coil steel. The steel is hot-pressed and cold-pressed into rolls. Formed coils mainly include hot-rolled steel coil and cold-rolled steel coil. Hot-rolled steel coils are processed products before billets are recrystallized. Cold-rolled steel coils are the subsequent processing of hot-rolled coils. The general weight of steel coil is about 15-30 tons. Grades of hot-rolled steel coils: Q195-Q420 Series, SS400-SS540 Series, S235JR-S355JR Series, ST Series, A36-A992 Series, Gr50 Series. A500 Grades of cold-rolled steel coils: Q195, Q215, Q235, 08AL, SPCC, SPCD, SPCE, SPCEN, ST12, ST13, ST14, ST15, ST16, DC01, DC03, DC04, DC05, DC06 Because steel coil products have high strength, good toughness, and a wide variety of steel specifications, they are widely used, ranging from general engineering structures to the manufacture of automobiles, bridges, ships, boilers, and pressure vessels. Various uses have different requiremen…
