Our Strengths
1. Rich experience
25 years’ experience in the production of comprehensive refractories and many intellectual property rights.
2. Advanced equipment and strong technical force
Relying on scientific and technological innovation, the company has developed GW SA series spinel refractory products, and 10 new technologies have obtained national patents.
3. Spinel Refractories fill the gap in domestic market
The appearance of GW SA series spinel refractories developed and produced by our company has fundamentally solved the core problem of short life of furnace body caused by non-chemical corrosion resistance and non-liquid erosion resistance of supporting materials of user equipment.
