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.

A515 Carbon Steel Coil

ASTM A515 carbon-silicon steel coils primarily for intermediate- and higher-temperature service in welded boilers and other pressure vessels. Coils are available in three grades having different strength levels: Grades 60, 65, 70, 415, 450, and 485.

Hot rolled coil

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.

A387 Carbon Alloy Steel Coil

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.
