Carbon steel coil is a metal coil made of carbon steel. It has the characteristics of high strength and good processing performance. It is widely used in construction, automobiles, ships and other fields.

Q195 carbon steel coil is a low-carbon structural steel with a yield strength of 195 MPa. The main component of this steel is carbon, but it also contains small amounts of other elements, such as silicon, manganese, sulfur, phosphorus, and so on. Due to the low carbon content (usually no more than 0.25%), Q195 carbon steel rolls have low hardness and strength, but relatively good toughness and ductility. This makes it easy to process and make into various shapes, so it has a wide range of applications in industry and construction.

Q235 carbon steel coil is a common carbon structural steel, also known as A3 steel. Where "Q" represents the yield limit of this material, and "235" refers to the yield value of this material, which is about 235MPa. The carbon content of this steel is moderate, so it has good comprehensive properties, including strength, plasticity and welding properties, which is also the reason why it is widely used.

Q345 carbon steel coil is a low-alloy, high-strength structural steel that belongs to the category of carbon structural steel. The "Q" in its grade represents the yield strength, and "345" indicates that the lower limit of the yield strength at room temperature is 345MPa. This steel complies with the GB/T 1591-2008 standard and is widely used in construction, bridges, vehicles, ships, pressure vessels, and cryogenic engineering.

Q255 carbon steel coil is a carbon structural steel, also known as Q255 carbon junction steel. The main characteristics of this steel is that it has good strength, plasticity and toughness, and also has good welding properties and cold and hot pressure processing properties. Its chemical composition mainly includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S) and other elements, of which the carbon content is usually between 0.18% and 0.28%.

ASTM A36 steel coil is one of the most common grades of steel used in structural applications. This mild carbon steel grade contains chemical alloys that give it properties such as machinability, ductility, and strength that are ideal for use in constructing a variety of structures.

Hot-rolled coil is a steel strip coil that is continuously produced from steel billets after being heated at high temperatures and then passed through a rolling mill. It has the characteristics of high strength, good toughness and easy processing, and is widely used in construction, automobiles, machinery and other fields.

ASTM A387 steel coil is chromium-molybdenum steel for pressure vessels for elevated temperature service. ASTM A387 steel coil include ASTM A387 Grade 5, Grade 9, Grade 11, Grade 12, Grade 22. Each A387 grade is divided into 2 class: class 1 and class 2.

ASTM A514 steel (also known as T1) grades incloud A, B, E, F, H, P, Q & S. This steel coil has a high yield strength and good weldability. ASTM A514 steel coil is quenched and tempered carbon-alloy steel. It is typically used when abrasion resistance and high-impact properties are required.
