Deep processing:
Steel pipe products can be further processed for easy use by customers.
We can provide deep processing with threads, grooves, galvanizing, painting, bending, welding and so on.
Pre galvanized steel pipe are mainly used in waterworks, petrochemical industry, chemical industry, power industry,
agricultural irrigation, urban construction. For liquid transport: water supply, drainage. For gas transport: gas, water vapor,
liquefied petroleum gas. For structural use: for piling pipe, as a bridge;
Hunan Hengan Weiye Metal Products Co., LTD is subordinate to Hengan Weiye Steel Pipe Co., LTD. After more than 10 years of development, the company has become a leading enterprise in the industry, with more than ten thousand tons of stock, with processing bases in Guangzhou, Tianjin, Hubei and other provinces.
Main business: seamless steel pipe, fine drawing pipe, drill pipe special steel pipe, steel plate, galvanized products, stainless steel series, and production and processing. Under the support and care of friends and Allies from all walks of life, after years of development, the company's performance continues to expand, the annual sales has exceeded 150 million.
At present, it has become a special agent dealer of well-known domestic steel enterprises. Under the situation of fierce market competition, the company has the courage to open up and innovation. At present, the company provides steel projects all over the world.
