Description
Product Description
ASTM A36 steel plates are low-carbon structural steel plates commonly used in a wide range of structural applications. The A36 Material Specification developed by ASTM International specifies the mechanical properties and chemical composition required for structural steel.
Applications
- Structural beams and columns in construction
- Heavy equipment manufacturing
- Bridges and infrastructure projects
- General fabrication and structural applications
Fabrication and Welding
ASTM A36 steel is easily fabricated and welded, making it suitable for a variety of structural applications. It can be cut, shaped, and formed into complex structures with standard welding processes such as MIG and TIG welding.
Standards and Certifications
ASTM A36 steel plates are manufactured according to ASTM standards and can be certified to meet specific quality and material specifications. Customers can request mill test reports or certification documentation.
Finishes
ASTM A36 steel plates can be supplied with various surface finishes, including hot-rolled, cold-rolled, and painted finishes, depending on the intended application and customer requirements.
