Square pipe and Angle steel are the most commonly used materials for display racks, using the welding paint technique.
Square pipe is a name for square pipes, that is, steel pipes with equal side lengths. When the bending and torsional strength are the same, the weight is lighter, so it is widely used in the manufacture of mechanical parts and engineering structures.
Square tubes are widely used in construction, machinery manufacturing, steel construction and other projects, in shipbuilding, solar power generation brackets, steel structure engineering, power engineering, power plants, agricultural and chemical machinery, glass curtain walls, automobile chassis, airports, boiler construction, highway railings , housing construction, pressure vessels, oil storage tanks, bridges, power station equipment, lifting and transportation machinery and other high-load welded structural parts are also widely used.
Angle steel, commonly known as angle iron in the industry, is a long strip of steel with two sides at right angles. The material is usually ordinary carbon structural steel and low alloy steel.
The characteristics of Angle steel:
1.the angular structure makes it have good support strength.
2. Under the same bearing strength, the weight of Angle steel is light, the consumption of materials is less, and the cost is saved.
3. the construction is more flexible, occupy less space.
Because of its high cost performance, Angle steel is widely used in housing construction, bridge, tunnel, wire tower, ship, bracket, steel structure and other fields, play the role of support or fixed structure.
