Product type
Hot rolled plates are flat steel products that are produced by rolling steel at high temperatures, typically above 1700°F. This process allows the steel to be shaped and formed easily, resulting in a product with a rough surface finish. Hot rolled plates are primarily made from carbon steel and are known for their excellent weldability and machinability, making them suitable for various structural applications.
| Thickness range | 0.25 to 12 inches |
| Width range | 24 to 120 inches |
| Length range | 96 to 480 inches |
| Material grade | ASTM A36, A572, A992 |
| Surface finish | Rough, mill scale present |
| Weight per unit area | Approximately 40 to 100 lbs per square foot |
When selecting hot rolled plates, consider the required material grade based on your application needs, such as ASTM A36 for general structural use or A572 for higher strength requirements. Specify the thickness, width, and length according to your project specifications. Additionally, inquire about tolerances and surface finish, as these can affect the performance of the plates in your application. Quantities may vary based on project needs, so be clear about your requirements when requesting a quote.
