Description
The black square pipe is used as the base material and is hot-dip plated by immersing it in high-temperature molten zinc liquid. The zinc layer is thick and has strong adhesion. The edges, corners, and weld seams are fully covered. It has extremely strong anti-corrosion and rust prevention capabilities, is resistant to wind and outdoor aging, and can last for over ten years. It is mainly used in outdoor steel structures, guardrails, factory frame skeletons, municipal projects, photovoltaic supports, etc., in open-air working conditions.
Core product advantages
The galvanized square pipe adopts a square structure design, which is evenly stressed, has good rigidity, and has excellent torsional and compressive resistance. Compared with round pipes, it is more convenient for splicing, welding, installation and fixation, and has a regular and beautiful construction forming effect. The surface zinc layer can isolate air and moisture, effectively prevent the pipe from rusting and oxidation, eliminates the need for subsequent painting and anti-corrosion processes, and significantly reduces the maintenance cost in the later stage. The product can be freely cut, drilled, bent, and welded, with excellent processing performance, and is suitable for various customized construction needs.
Common materials and specifications
The regular materials are mainly Q235B and Q355B, with good toughness and high strength. The specifications are complete, covering a full range from 20×20mm to 400×400mm, with wall thicknesses ranging from 1.2mm to 16mm. It supports standard sizes and non-standard customization, and complies with national standards GB/T 6725 and GB/T 6728, with precise dimensions and stable quality.
Main application scenarios
It is widely used in various engineering fields such as building steel structures, factory frame skeletons, curtain wall keels, municipal guardrails, fence steel structures, photovoltaic supports, equipment bases, steel structures for indoor and outdoor decoration projects, traffic facilities construction, etc. Due to its durability, aesthetics, no need for painting, and high cost-effectiveness, it has become the preferred type of material for steel structure projects.
