Steel plates are types of flat steels that can be cut and welded into finer products. As the high-temperature steel is rolled into a plate, the strength of the steel plate is given. Layer upon layer of steel is compressed and forged into a piece of steel until it reaches the appropriate dimensions. They are often used to reinforce foundations and support heavy items, such as bridges. At the same time, this material provides an important foundation for building larger structures and non-machinable parts. The steel manufacturers are able to create the proper blend of materials to make a steel plate suitable for bridge building or skyscraper construction. Each use of steel plates is job-specific, where climate and temperature factors are crucial in the composition of steel.
1. Compared with sheets or coils, hot rolled steel plates are known for their outstanding flatness, mechanical properties, and superior performances when it comes to strength, fabricability, toughness, etc.
2. Hot rolled steel plates can be further processed by heat treatment in order to improve their mechanical properties.
