Galvanized Steel Tube

Tianjin Shuncheng Industrial's Galvanized Steel Tubes are made from ordinary carbon structural steel or low-alloy structural steel round pipes as the base material, treated with hot-dip galvanizing or electro-galvanizing processes to form a uniform and dense zinc layer on the inner and outer surfaces of the pipe. Its core function is to provide long-term corrosion protection to the base material through the sacrificial anode protection of the zinc layer, while also retaining the basic characteristics of round pipes such as pressure bearing, transportation, and support. It can be widely used in fluid transportation, structural support, frame construction, and other scenarios, adapting to various indoor and outdoor environments, and is especially suitable for humid and highly corrosive working conditions.

The product boasts five core advantages: The zinc layer bonds tightly to the substrate, forming a double protective barrier that effectively isolates corrosion, extending its service life to 20-30 years (depending on the usage environment), significantly reducing subsequent maintenance costs; the substrate is made of high-quality steel, processed through multiple steps, exhibiting excellent pressure resistance, bending resistance, and impact resistance, with strong structural stability; the surface is smooth, supporting welding, flange connections, and other methods; it is lighter than solid steel of the same specifications, facilitating handling and installation, and improving construction efficiency; compared to stainless steel pipes and other anti-corrosion pipes, it has lower production costs, achieving a balance between low cost and high durability; it adopts an environmentally friendly galvanizing process, ensuring the zinc layer meets national standards and contains no excessive levels of harmful heavy metals, making it suitable for applications such as drinking water transportation; and waste pipes can be recycled and reused, aligning with the concept of green development.

Product application scenarios

Application Scenarios: Urban water supply and drainage pipelines, gas transmission pipelines, municipal greening fences, street light pole supports, underground pipe gallery supports, etc.

Case Study: A water supply and drainage pipeline renovation project in the old city area of a provincial capital city selected DN100-DN300 hot-dip Galvanized Steel Tubes as the main transmission pipelines, laying a total of 28 kilometers. Thanks to their excellent corrosion resistance and suitability for the damp underground environment, the project solved the problems of easy rusting and leakage in the original pipelines, ensuring the safety of residents' water supply.

2. Construction Engineering Field

Application Scenarios: Building main structure support, scaffolding erection, fire protection pipelines, air conditioning and ventilation ducts, roof drainage pipelines, etc.

Case Study: A large commercial complex construction project used DN50-DN200 Galvanized Steel Tubes to construct a fire sprinkler system and scaffolding support system. The total amount of pipes exceeded 1,500 tons. This not only met the corrosion resistance and pressure resistance requirements of the fire protection pipelines but also ensured the structural stability of the scaffolding. The project successfully passed fire safety and engineering quality inspections.

3. New energy fieldApplication Scenarios: Photovoltaic power station brackets, wind turbine tower auxiliary supports, and new energy charging pile frames, etc.

Case Study: A large-scale centralized photovoltaic power station project used φ48×3.0 hot-dip Galvanized Steel Tubes to manufacture photovoltaic module brackets, totaling over 800 tons. Suitable for outdoor, windy, and sandy environments, the zinc layer effectively resists ultraviolet radiation and wind and sand erosion, ensuring the service life of the brackets and the installation stability of the photovoltaic modules.

4. Agricultural sectorApplication Scenarios: Greenhouse frames, farmland irrigation pipes, livestock shed construction, etc.

Case Study: A modern agricultural industrial park greenhouse project used φ25×2.0 and φ32×2.5 Galvanized Steel Tubes to construct the greenhouse frames, building a total of 50 standardized greenhouses. The pipes are lightweight and corrosion-resistant, suitable for the high humidity environment inside the greenhouses, and also have good load-bearing capacity, supporting the installation of insulation film and shade netting.
