Cast Iron Plant: Where Quality Meets Precision

Introduction to the Cast Iron Plant

Our Cast Iron Plant is a hub of excellence in producing cast – iron products. With a focus on quality and precision, we utilize advanced techniques to transform raw materials into high – performance cast iron items. Whether you need components for industrial machinery or decorative elements, our plant has the capabilities to deliver.

Cast Iron Grades Offered

We offer a wide range of common cast iron material grades. Gray Cast Iron (ASTM A48) is known for its excellent machinability and damping properties. It’s ideal for applications where vibration absorption is crucial, like in machine tool bases. Ductile Cast Iron (ASTM A536), on the other hand, combines the strength of steel with the castability of iron. It’s highly versatile and used in automotive parts, pipes, and more.

We also adhere to international standards such as AS 1830, AS 1831, DIN EN 1561, and DIN EN 1563. These standards ensure that our products meet the highest quality benchmarks, making them suitable for global markets.
