Alliance Steel offers a variety of coated steel sheet and coil products and value-added services to meet customer needs.
The steel is coated with zinc to help prevent corrosion. The zinc reacts with oxygen when exposed to the atmosphere, forming a zinc oxide that further reacts with carbon dioxide to form zinc carbonate. It stops further corrosion in many circumstances, protecting steel from the elements.
We supply a variety of coated steel sheet and coil products, including hot dipped, electro galvanized, aluminized, galvannealed and galvalume. Our value-added service capabilities include slitting, shearing, blanking, stretcher leveling, degreasing and brushing and metallurgical support.
Applications for Coated Steel Products
Coated steel is ideal for customers seeking an economical, effective way to protect steel from corrosive environments. The zinc coating not only serves as a barrier between the steel and the elements, but it will sacrifice itself to protect the underlying steel. Industries that use coated steel products include:
- Automotive
- Pipe and Tubular
- Outdoor Recreation
- Agriculture
- Construction
