Product Description

The company is committed to manufacturing high-end anti-corrosion pure water hydraulic support columns and jacks, with 30 years of research and development, design, production and sales experience, and widely serves hydraulic support manufacturers nationwide. At present, it has developed into one of the largest coal engine oil cylinder production bases in China, with an annual production capacity of 24000 tons, 200000 pieces, and an annual output value of 500 million yuan. Product specifications from φ 63mm to φ530mm. There are a total of more than 50 types (oil red inner diameter division of this specification), all of which have passed the testing and inspection of the National Mining Product Safety Mark Center. Besides, our company has obtained relevant qualifications such as safety mark certificates, and has various surface treatment capabilities such as copper melting, flame support, copper plating, engraving, PIP, etc., and can meet the needs of different customers.
