Technical Support
Considering some customers are not very professional in manhole covers, they may only know they need manhole covers, but they don’t understand some detailed specifications and loading ability.
Based on our rich experience in this industry, we help customers design and choose the right manhole cover.
First of all, we help clients design the size, shape and weighing level of cast iron manhole cover for customers based on customer communication. Then use CAD or solidworks software to design models for customers.
If customers need to add LOGO and patterns, we will also design for customers in the computer modeling stage.

Iron Mould for Sand Box
At the beginning of making ductile iron manhole covers, the sandboxes were manually made one by one. That waste time and labor, and not efficiently.
We have advanced production lines, the sand boxes for cast iron foundry are pressed by machine, the efficiency is very high, the precision is also very good, the manhole cover produced is very delicate.
We can design and make the moulds for customers, greatly improving the production speed and product quality.
