Yes, we specialize in OEM services. We can manufacture manhole covers, gratings, and casting parts according to your detailed design drawings, specifications, and actual samples.
Ductile iron contains nodular graphite, which provides significantly higher strength, ductility, and impact resistance compared to the brittle nature of standard grey cast iron.
We provide a versatile range of casting processes including sand casting, precision casting, and die casting to meet various complexity and volume requirements.
Our quality assurance involves strict management and adherence to the BS EN124 standard, utilizing advanced testing equipment and experienced workers to verify every product.
Beyond manhole covers, we produce gully gratings, trench covers, surface boxes, and various machining parts in aluminum, brass, bronze, and stainless steel.
