Square tube made of steel plate or steel strip after crimping and welding is formed by a series of chemical reactions in hot dip galvanizing pool

Hot-dip galvanized square pipe is a square pipe made of steel plate or steel strip after crimping and welding, which is formed by a series of chemical reactions in hot-dip galvanized pool. It can also be a hollow square cross-section steel pipe made by cold bending of hot-rolled or cold-rolled galvanized steel strip and then high frequency welding. The production process of the pipe is simple, the production efficiency is high, the variety specifications are many, and the equipment is less, but the strength is generally lower than that of the seamless square pipe.

Concept

Representation method
Example: Square pipe 50*50* 5*6m, expressed as: 50(width) 50(width)5 (wall thickness) 6m (meters). Because the square tube is equilateral, that is, the common meter number is 6 meters; The general industry is simply expressed as: 50*5 parties.

According to the expression method of square pipe, square pipe generally takes edge width and wall thickness as the expression standard.

Performance

Hot-dip galvanized square pipe has good strength, toughness, plasticity, welding and other process properties and has good ductility, its alloy layer is firmly attached to the steel base, so the hot-dip galvanized square pipe can be cold stamping, rolling, wire drawing, bending and other forms without damaging the coating;

Suitable for general processing such as drilling, cutting, welding, cold bending and other processes. The surface of hot-dip galvanized parts is bright and beautiful, and can be directly used in engineering according to demand.

Classification

Hot-dip galvanized square pipe has seamless and weld points, seamless square pipe is the seamless round pipe extrusion molding.

Purpose

Hot-dip galvanized square pipe because of its excellent performance is often used in: glass curtain wall, power tower, communication grid, water and gas transmission, wire bushing, housing, Bridges, metal structure, power transmission, etc., has been widely used in recent years.
