Application of square tube

1. Construction and steel structure

- Uses: used for building bridges, steel structure factories, gymnasiums, airport terminals, etc.

- Advantages: high strength, light weight, good seismic performance, suitable for large-span structures; the surface can be galvanized to prevent rust and prolong service life.

2. Machinery Manufacturing

- Uses: manufacturing machine tool components, frames for construction machinery, support structures for automation equipment, etc. Advantages: easy to weld and cut; can be galvanized to prolong service life.

- Advantages: easy to weld and cut, customizable size to meet the needs of complex mechanical design.

3. Furniture and display racks

- Uses: shelves, storage racks, display cabinets, shelf dividers, etc.

- Advantage: flat surface, strong load-bearing capacity, and can be painted, plated to enhance the aesthetics.

4. Automobile and transportation

- Uses: automobile chassis parts, carriage frames, railroad vehicle structural parts.

- Advantage: lightweight design to reduce energy consumption, while ensuring structural stability.

5 agriculture and animal husbandry

- Uses: greenhouse skeleton, farm fencing, agricultural equipment support.

- Advantage: corrosion resistance (such as galvanized or stainless steel), adapt to the harsh outdoor environment.

6. Electricity and communications

- Uses: power transmission towers, communication base station brackets, cable bridges.

- Advantages: high wind pressure resistance, customized anti-corrosion coating to adapt to outdoor environment.

7. Decorative engineering

- Uses: staircase handrails, balcony guardrails, architectural decorative lines.

- Advantage: simple lines, can realize diversified appearance by spray painting or wood grain transfer printing.

8. Municipal engineering

- Usage: street light pole, traffic sign pole, billboard support.

- Advantages: standardized production, convenient installation, taking into account the strength and aesthetics.

9 energy and environmental protection

- Uses: solar energy bracket, wind turbine tower, sewage treatment equipment structural components.

- Advantage: corrosion-resistant materials (such as stainless steel) to adapt to the outdoor and chemical environment.

10 marine and ship

- Uses: ship deck structure, dock piling, offshore platform support.

- Advantage: Adopt seawater corrosion-resistant materials to meet the requirements of high strength and long-term durability.

Material selection and specification considerations

- Material: Ordinary carbon steel (economic and general purpose), galvanized steel (anti-rust), stainless steel (corrosion resistance), aluminum alloy (lightweight).

- Specification: Wall thickness and side length are selected according to the load demand, for example, square tubes for construction are mostly more than 50×50mm, and 30×30mm is optional for decoration.
