Shixinda’s manufacturing facility is located within one of China’s most concentrated steel industrial clusters. As a manufacturer of seamless square and rectangular tubes, the company produces these tubes by cold-drawing pierced mother pipes and cutting them to specified lengths. The tube wall consists of a single, continuous piece of steel—free of burrs requiring smoothing, weld seams requiring avoidance, or joints susceptible to stress-cycling fatigue.

Located in one of Northern China’s most concentrated steel industry clusters, the Tianjin Shixinda facility is an experienced manufacturer of longitudinally welded square and rectangular tubes. These tubes feature stable weld seams and a comprehensive range of specifications, striking an optimal balance between strength and procurement costs. Capable of meeting material requirements for large-scale standard engineering projects and offering rapid supply response, they represent a highly cost-effective choice for applications involving moderate loads.

For over eight years, Shixinda has been supplying cold-drawn square and rectangular tubes from the Daqiuzhuang steel distribution hub in Tianjin, establishing itself as a reliable manufacturer. These tubes are produced using round steel billets as raw material; they are formed through a multi-pass, forced-drawing process using dies at ambient temperature, followed by annealing to relieve internal stress, resulting in hollow sections with square or rectangular profiles.

Shixinda is a Tianjin-based manufacturer of cold-formed square and rectangular tubes, supplying structural hollow sections to steel structure fabricators, greenhouse builders, and photovoltaic mounting contractors. These tubes are cold-formed from Q235B, Q355B, and S355JR steel strips and are available with an optional hot-dip galvanized finish.

Shixinda Steel Company possesses eight years of practical experience in supplying materials for photovoltaic and steel structure projects. As a manufacturer of hot-rolled square and rectangular tubes, the company produces tubing characterized by high overall strength and excellent impact resistance; these products are capable of withstanding harsh conditions—such as the low temperatures of the north and prolonged outdoor sun exposure—thereby ensuring structural stability and safety while meeting the material requirements of high-load engineering projects.

ShixinDa's Zinc Aluminum Magnesium L Profile are manufactured using high-quality base materials such as Q235B, Q355, and S350GD to form a triple-alloy zinc-aluminum-magnesium coating through a continuous hot-dip galvanizing process. These profiles encompass both equilateral and irregular L-shaped cross-sections, with a comprehensive range of specifications available and support for customization. The product's coating structure is dense and stable; thanks to its unique magnesium-based formulation, it features a core self-repairing capability – enabling the spontaneous formation of a passivation protective film on cut or scratched surfaces, eliminating the need for manual repainting or repair.
