We are a modern high-tech enterprise integrating R&D, production, sales, after-sales service and technical support of galvanized steel pipes. Specializing in providing high-quality and cost-effective galvanized steel pipe products for various infrastructure projects, we have become an industry benchmark with mature technology, strict quality control and comprehensive services, winning widespread praise and long-term trust from customers at home and abroad.
Our company offers a complete range of products, covering DN15-DN300 (Φ18-Φ325mm) diameter, 1.0-12.0mm wall thickness, with materials including Q195, Q215, Q235B, Q355B, etc. We can customize products with different processes such as hot-dip galvanizing and electro-galvanizing (cold galvanizing) according to customer requirements. The galvanized layer thickness can reach 60-85μm, with strong adhesion and excellent corrosion resistance, suitable for different usage environments and extending product service life. Our products are widely used in fire protection engineering, water supply and drainage systems, gas transmission, building curtain walls, scaffolding construction, power threading, greenhouse greenhouses, guardrail fences, municipal engineering, agricultural irrigation and other fields. With the advantages of good corrosion resistance, easy installation, high strength and excellent cost performance, our products have become the preferred pipe material for various projects.
In terms of production technology, we adhere to the craftsman spirit and strict quality, fully complying with national authoritative standards such as GB/T 3091-2015 and GB/T 13793-2016, and controlling product quality throughout the process. Raw materials such as high-quality strip steel and welded pipe base materials undergo strict physical and chemical inspections before production to eliminate unqualified raw materials from entering the production line at the source; the galvanizing process adopts advanced hot-dip galvanizing technology, and the steel pipes are treated through multiple processes such as pickling, rinsing, fluxing, drying, hot-dip galvanizing, cooling and passivation to ensure uniform galvanized layer without missing plating or bubbles; the finished product inspection implements a dual standard of "100% inspection + first article inspection". Each batch of products is tested for galvanized layer thickness, adhesion, uniformity and mechanical properties, and each steel pipe undergoes a hydrostatic test to ensure compliance with pressure resistance standards, eliminate defects such as pinholes and incomplete welding, and ensure that every steel pipe leaving the factory meets standards and quality requirements.
