katalor Steel, make life better

1.The properties of steel make innovation possible and make creativity a reality. Steel makes possible the art of engineering.

 

2.The new lightweight steel is lighter and more flexible, while maintaining the high strength required.

 

3.Modern steel products get increasingly complex and sophisticated. From intelligent car  to high-tech computers, from medical equipment to the most advanced satellites, modern steel products are inseparable from the application.

 

4.Architects can create any shape or span they want, and a steel structure can meet their innovative design needs.

 

5.New and better way to make modern steel every year. In 1937, 83,000 tons of steel were used to build the Golden Gate Bridge, half as much as today.

 

ASTM A709 Grade 50 steel plate is a high-quality steel suitable for steel structures, especially bridges and construction machinery components that require high weldability and toughness.
