Din galvanized steel tube with high precision

The Din galvanized steel tube with high precision from Shanghai Tianyang Steel Tube Co., Ltd is manufactured to DIN 2391-2 standards, with outer diameters ranging from 10 mm to 150 mm and wall thicknesses between 0.8 mm and 10 mm. The tubes feature a hot-dip galvanized coating with a minimum zinc layer weight of 60 g/m², as confirmed by the supplier’s process documentation. Dimensional tolerances for diameter are ±0.1 mm and for wall thickness are ±5%, ensuring consistency for precision assembly applications.

The base material is typically cold-drawn seamless carbon steel, conforming to DIN 1629 Grade ST37.4 or equivalent. The galvanizing process provides cathodic protection against corrosion, making these tubes suitable for outdoor or humid environments. While the supplier does not specify the exact steel grade beyond DIN compliance, the typical industry practice for high-precision tubes includes phosphatized or passivated surface treatments to enhance paint adhesion and reduce white rust formation during storage.

These tubes are commonly used in mechanical engineering, structural frameworks, hydraulic systems, and automated machinery where dimensional accuracy and corrosion resistance are critical. Buyers include manufacturers of industrial equipment, automotive component suppliers, and construction firms sourcing structural elements. Trade terms include FOB Shanghai and CIF, with packaging in bundles secured by steel straps and plastic end caps. Minimum order quantities are not stated and must be confirmed directly with the supplier.
