Steel  coils are classified according to their professional uses, including oil drum plates, bulletproof plates, shipbuilding plates, automobile plates, construction plates, machining plates, etc. Specializing in the production and sales of carbon steel coils, factory direct sales, product grades and specifications are complete, and can certainly meet your various needs, welcome to consult

Size:Ф20～Ф300 Standard:YB/T4149 GB/T 33145 GB/T 5310 ASTM A335/A335M API 5L Used for making steel pipes for high pressure gas cylinders, oil exploitation, thermal power generation, natural gas transmission and other fields.

A36 is a carbon structural steel coil whose chemical composition and mechanical properties strictly conform to American ASTM standards. Good mechanical properties, welding performance and corrosion resistance are basically why they are widely used in construction, bridges, machinery manufacturing and other fields.

Round steel belongs to carbon structural steel for construction and machinery, while square steel belongs to carbon structural steel for machinery. Both of them are simple section steel, and their section shapes are respectively round and square. Low carbon is mainly used for drawing wire, forging rivets, bolts, nuts and other metal products of raw materials. Medium carbon round steel and square steel are generally used to make mechanical structural parts.
