Product Description

We are iron foundry!

Use high quality raw materials and do continuous quality inspection.

We are a professional iron foundry with rich experience, outstanding capacity, and commitment to eco - friendly production.
Our 80,000 - square - meter factory has modern workshops and advanced equipment like furnaces and casting machines for various orders.

We offer diverse cast - iron products for construction (drainage gratings, manhole covers), machinery ( transmission wheels, engine parts), and more (water pump housing, umbrella bases). Customization is our strength for specific material, size, shape, and performance requirements.

Quality and environmental protection are top priorities. We're ISO 9001, ISO 14001, and ISO 45001 certified. We start with high - quality, eco - friendly raw materials and closely monitor production to minimize waste and emissions. Advanced inspection ensures products exceed industry standards with lowest environmental impact.

Our team provides pre - sale consultation and support, updates on order progress during sales, and offers warranties and prompt feedback after sales for long - term partnerships.
