Stainless steel square tubes are widely used in various fields due to their excellent corrosion resistance, high strength, and beautiful appearance. The following is a detailed summary of its main application scenarios:
1、 Architecture and Decoration Field
Building structural support
Stainless steel square tubes serve as building frames, columns, and beams, providing stable support, especially suitable for high-rise buildings, bridges, and large venues.
For example, in landmark buildings such as Shanghai center Building and Bird’s Nest, stainless steel square tubes are used for curtain wall support and structural reinforcement.
Indoor and outdoor decoration
Railings and handrails: Stainless steel square tubes are commonly used for handrails in shopping malls, hotels, residential staircases, balconies, and public places, which are both safe and aesthetically pleasing.
Wall and ceiling decoration: Stainless steel square tubes can be polished, brushed or plated to create modern indoor spaces, such as hotel lobbies and art galleries.
Furniture manufacturing: Furniture frames such as dining tables, chairs, bookshelves, etc. utilize the lightweight and corrosion-resistant properties of stainless steel square tubes to enhance product durability.
Landscape Engineering
The sculptures, lamp posts, flower stands and other landscape facilities in parks and squares are made of stainless steel square pipes to resist wind and rain erosion and maintain long-term beauty.
2、 Industrial and mechanical fields
Fluid transport pipeline
Chemical and petroleum industries: transporting corrosive liquids or gases (such as acid, alkali, salt water), the corrosion resistance of stainless steel square pipes (such as 316L material) ensures long-term stable operation of pipelines.
Food and pharmaceutical industry: used for the transportation of purified water, beverages, and drugs, in compliance with hygiene standards and to avoid contamination.
Gas transportation: Pipeline systems for industrial gases such as oxygen and nitrogen, with high strength and sealing of stainless steel square tubes to ensure safety.
Mechanical parts manufacturing
Bearings and gears: Stainless steel square tubes, after precision machining, can be used as mechanical transmission components to withstand high loads and friction.
Frame and bracket: The frame structure of automation equipment, robots, and CNC machine tools utilizes the stability of stainless steel square tubes to improve equipment accuracy.
Hydraulic system: As a supporting structure for hydraulic cylinders and oil pipes, it resists high pressure and vibration.
Automobiles and Transportation Vehicles
Exhaust pipe system: Ferritic stainless steel square tubes (such as 409 stainless steel) are used for automotive exhaust pipes, which are resistant to high temperatures and corrosion, and extend their service life.
Frame and structural components: The frame of electric vehicles and motorcycles is made of lightweight stainless steel square tubes to enhance endurance and safety.
3、 In the field of energy and environmental protection
solar mounting bracket
Stainless steel square tube, as the supporting structure of solar panels, has strong weather resistance and can withstand harsh environments such as wind, sand, rain, and snow.
Sewage treatment equipment
The corrosion resistance of stainless steel square pipes used for pipelines, brackets, and reaction vessels in sewage treatment plants prevents the erosion of equipment by sewage.
Ocean Engineering
Offshore platforms: Double phase stainless steel square tubes (such as 2205 stainless steel) are used as support structures for offshore platforms to resist seawater corrosion and wave impact.
Shipbuilding: The hull frame, deck railings, etc. are made of stainless steel square tubes to enhance the durability of the ship.
