Product Information

chequer plate direct are medium strength alloy plates with exceptional corrosion resistance. Aluminum sheet plates are created by surpassing aluminum between rolls underneath pressure, it becomes thinner and longer in the moving direction.

Mechanical strength, rust resistance and dimensional stability are key aspects that give these chequer plate direct the advantage over standard aluminum plates. The chequer plate direct  lend itself only to resistance welding. These plates have good workability but varies in tempers. The alloy plates are available in variety of sizes and thickness.

These chequer plate direct are made from marine grade alloys and find usage in manufacturing of fast ferries, yachts, navy or passenger vessels and small pleasure crafts.
