About Our Facility

Xiamen Manufacturing Base

The factories have set up their ISO9001 & QS9000 Quality Control Systems and obtained certificates issued by DNV. Our factories operate on advanced production equipment including intermediate-frequency heating forging assembly line, automatic multi-stage cold puncher, numerically controlled lathe, automatic heat treatment net furnace that is controlled by atmosphere microprocessor, imported precision mold processing center, imported spectral analyzer, universal material tester, metallographic microscope and magnetic particle tester.

We also maintain long-term cooperative relationships with domestic steel specialists for research and development projects and to ensure the quality of our products. Our specialties are the high tensile 10.9 and 12.9 class. We only acquire two brands of materials (S40Cr for 10.9 and ML20MnTiB for 12.9 class) to ensure high quality while maintaining lower cost of materials and stocking.

Strategically positioned near Xiamen Port, one of China's largest container ports, we offer efficient logistics and competitive shipping to clients worldwide. Our products are exported to North America, Europe, Southeast Asia, Taiwan and other areas.
