Over the years, the foundry has successfully challenged the traditional wisdom in producing one off products of demanding grades and in turn earned the respect from its clients. We cater to various industries (marine, oil & gas, dredging and pumps) producing numerous parts such as:

• Dredging components (liners, wear plates and spud carrier parts)
• Pump components (impellers, wear rings, diffuser bowls and casings)
• Blow bars
• Gearbox housings
• Crusher wear parts
• Sheaves
• Gypsy wheels
• Marine thruster parts
• BOPs
