Good Quality Hollow Section Tube - Hot Dipped Galvanized Square Pipes – Zheyi Detail:

Hot Dipped Galvanized Square Pipes It is a square tube made of steel plate or steel belt after crimping forming and welding in hot dip galvanizing pool through a series of chemical reactions forming square tube; Can also be hot rolled or cold rolled galvanized steel strip after cold bending, and then high-frequency welding of a hollow square section steel pipe. The production process of the pipe is simple, high production efficiency, variety of specifications, less equipment, but the general strength is lower than seamless square pipe.

Hot Dipped Galvanized Square Pipes, Concept

Said method

For example: square tube 50*50*5*6m, denoted as: 50(width)* 50(width)*5 (wall thickness)* 6m (number of meters). Because the square tube is equilateral, that is, the number of meters commonly used is 6 meters; The general industry is simply expressed as: 50*5. According to the expression method of square tube, square tube generally takes side width and wall thickness as the expression standard.

Hot Dipped Galvanized Square Pipes, Performance

Hot Dipped Galvanized Square Pipes It has good strength, toughness, plasticity and welding process performance and good ductility. Its alloy layer is firmly attached to the steel base, so the hot-dip galvanized square tube can be cold punching, rolling, drawing, bending and other molding without damage to 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 for engineering according to demand.

Hot Dipped Galvanized Square Pipes, Classification

Hot Dipped Galvanized Square Pipes There are seamless and weld points, seamless square tube is the seamless tube extrusion molding.

The material:Carbon Q235 (A, B); Low alloy Q345 (A, B)

Hot Dipped Galvanized Square Pipes, Application Areas

Furniture steel square tube, engineering building decoration, glass curtain wall, doors and Windows, steel structure, guardrail, machinery manufacturing, automobile manufacturing, electrical home appliances manufacturing, shipbuilding, container manufacturing, electricity, agricultural construction, agricultural greenhouse, bicycle, motorcycle frame, shelves, fitness equipment, leisure travel supplies, steel furniture, all kinds of oil casing, tubing, and line pipe, water, gas, sewage, Air, heating and other fluid transportation, fire fighting and supporting, construction, ETC.

Hot Dipped Galvanized Square Pipes, A Formula To Calculate

Calculation formula for ordinary square pipe per meter :( length + width) *2* wall thickness *0.00785 = weight per meter; calculation formula for hot-dip galvanized square pipe :( length + width) *2* thickness *0.00785*1.06= weight per meter

Galvanized steel square tube divided according to the shape of the section, is a name for square pipe and rectangular pipe, that is, steel pipes with equal and unequal side lengths. It is made of strip steel that has been processed and rolled. Generally, the strip is unpacked, flattened, coiled, welded to form a round tube, and then rolled into a square tube from the round tube and then cut to the required length.
