Square & Rectangular Steel Tube is a name of square tube and rectangular tube, that is the side length is equal and unequal steel tube. Also known as square and rectangular cold formed hollow section steel, square tube and rectangular tube for short. It is made of strip steel through processing and rolling. Generally, strip steel is unpacked, leveled, crimped, welded to form a round tube, which is then rolled into a square tube and cut to the required length.
What are the classifications of rectangular tubes?
Square rectangular tube according to the production process: hot rolled seamless square tube, cold drawn seamless square tube, extrusion seamless square tube, welded square tube.
The welded square tube is divided into:
1. According to the process, it is divided into arc welding square tube, resistance welding square tube (high frequency, low frequency), gas welding square tube and furnace welding square tube.
2. According to the weld, it is divided into straight seam welded square tube and spiral welded square tube.
Square Tube according to the material: ordinary carbon steel square tube, low alloy square tube.
1.general carbon steel is divided into: Q195, Q215, Q235, SS400, 20# steel, 45# steel and so on.
2. low alloy steel is divided into: Q345, 16Mn, Q390, ST52-3 and so on.
Square tube is classified by section shape:
1. simple section square tube: square tube, rectangular square tube.
2. complex section square tube: flower square tube, open square tube, corrugated square tube, shaped square tube.
Square tube according to surface treatment: hot dip galvanized square tube, electric galvanized square tube, oil coated square tube, pickling square tube.
Use of rectangular tube
Application: Widely used in machinery manufacturing, construction industry, metallurgical industry, agricultural vehicles, agricultural greenhouses, automobile industry, railway, highway guardrail, container skeleton, furniture, decoration and steel structure fields.
Used in engineering construction, glass curtain wall, door and window decoration, steel structure, guardrail, machinery manufacturing, automobile manufacturing, household appliance manufacturing, shipbuilding, container manufacturing, electric power, agricultural construction, agricultural greenhouse, bicycle rack, motorcycle rack, shelves, fitness equipment, leisure and tourism supplies, steel furniture, various specifications of oil casing, oil tubing and pipeline pipe, water, gas, sewage, air, mining Warm and other fluid transmission, fire and support, construction, etc.
