Steel Coil
Steel coil refers to rolled steel products in coiled form via hot rolling or cold rolling. It can be cut and flattened into steel sheets, featuring convenient transportation, flexible processing and customizable sizes, widely used as basic raw materials across all manufacturing industries. It covers four sub-types with distinct features and applications.
PRODUCTS
ST37 Carbon Steel Coil
St 37 steel is a low-carbon structural steel commonly used for manufacturing various structural components and mechanical parts. Its most common equivalent grades are the U.S. standard AISI 1008/1010 or the European standard S235JR.
SPCE Cold Rolled Steel Coil
SPCE steels can be drawn to a greater depth and more flexibly as compare to SPCD steels. SPCE steels are deep drawing quality cold rolled steels, which are consumed for drawing applications.This material is valid for drawing operation where the depth of the drawn part exceeds its diameter. The appropriate thickness for this SPCE material as demarcated in the JIS G3141 starts from 0.25 mm to 2.5 mm. However the width of SPCE material ranges to 2000 mm.
Q195 Cold Rolled Steel Coil
Q195 Cold Rolled Steel is a Chinese plain carbon structural steel, yield strength: 195 MPa, tensile strength: 315-430 MPa, material density: 7.85 g/cm3. “Q” is the first letter of Chinese spelling of “qu fu dian”, the translation is “Yield Point” or “Yield Strength”, “195” is indicates the unit value “195 MPa”.
1020 Carbon Steel Coil
1020 carbon steel is a commonly used plain carbon steel. It has a good combination of strength and ductility and can be hardened or carburized.1020 carbon steel which contains 0.12 to 2% carbon. This steel category gains hardness and strength with heat treatment when the percentage of carbon content increases but the ductility is reduced.
SS400 Carbon Steel Coil
SS400 according to material grade and name defined in the JIS G 3101 standard, The first S stands for "Steel", the second S stands for "Structure", and 400 for the lower limit tensile strength of 400 MPa. Ordinary structural steel with a tensile strength of 400 Mpa.This steel is the most widely used in JIS standard. Its use covers structures such as bridges, ships, vehicles, etc., in the shape of steel plates, steel bars and sections, almost all auxiliary materials for machinery and structures are used.
S235JR Carbon steel coil
S235JR is a European standard non alloy structural steel, which is equivalent to the national standard Q235B, that is, carbon structural steel with low carbon content. It is widely used for welding, bolting and riveting structures. It can also be used for building, bridge, ship, vehicle structural parts, manufacturing various tools, cutting tools, molds and measuring tools.
A36 Carbon steel coil
A36 is an American standard carbon structural plate, which is subject to ASTM A36/A36M. This standard is applicable to riveting, bolting and welding structures for bridges and buildings, as well as general purpose structural steel quality carbon steel sections, plates and bars.
SPHC Carbon steel coil
SPHC steel (JIS G 3131) is a hot-rolled mild steel sheet under the Japanese Industrial Standard. It offers good formability and weldability, commonly used for general structural purposes. The surface quality is typically in the as-rolled condition, suitable for applications where surface finish is not critical, such as structural components, pipes, automotive parts, and general machinery components.
In standard classification, hot-rolled steel sheets (such as SPHC) and cold-rolled steel sheets (such as SPCC, SPCD in JIS G 3141) belong to different categories. The previously mentioned designations like DC01 (1.0330), DC03 (1.0347), etc., refer to European standard cold-rolled steel grades and are not equivalent to SPHC.
DC01 Carbon steel coil
DC01-A: Defects that do not affect the formability or surface coating are allowed, such as air holes, slight dents, small marks, slight scratches and slight coloring.
DC01-B: The better surface shall be free of defects that may affect the uniform appearance of high-quality paint or electrolytic coating. The other surface shall meet at least surface quality A.
The main application fields of DC01 materials include: automobile industry, construction industry, electronic equipment and household appliances industry, decorative purposes, canned food, etc.
