Information summary：Square tube is a type of steel with a hollow cross-section and rectangular edges. Due to its high structural strength, good plasticity, and diverse specifications, it is widely used in multiple industries. The following are the application scenarios and specific uses of square tubes in major industries:

Square tube is a type of steel with a hollow cross-section and rectangular edges. Due to its high structural strength, good plasticity, and diverse specifications, it is widely used in multiple industries. The following are the application scenarios and specific uses of square tubes in major industries:
1、 Construction industry
The application of square tubes in the field of construction is the most common, mainly used for:
Structural support: such as the frame structure, scaffolding, tower crane brackets, etc. of building construction, which utilize their high strength and stability to bear weight.
Decoration and Curtain Wall: Used for door and window frames, indoor and outdoor decorative lines, stair handrails, railings, etc., with both aesthetics and practicality.
Pipeline system: used as an installation carrier for water supply and drainage pipelines, ventilation pipelines, or as a protective sleeve for underground pipelines.
2、 Manufacturing industry
1. Mechanical manufacturing: used for manufacturing machine tool frames, mechanical components (such as brackets, guide rails), conveying equipment (such as assembly line brackets), etc., to meet the strength and accuracy requirements of mechanical structures.
2. Automobiles and Rail Transit:
Automotive industry: used for body frames, chassis brackets, crash beams, exhaust pipe brackets, etc., to reduce body weight while ensuring safety.
Rail transit: such as the carriage frame, luggage rack support structure, and signal equipment bracket next to the track of high-speed rail and subway.
Ship and Aviation: Deck supports inside ships, cabin partitions, and lightweight supports in the aviation field (such as drone frames).
3、 Energy and Chemical Industry
1. Petroleum and natural gas: used for oilfield derricks, pipeline supports, oil and gas transmission pipelines (requiring anti-corrosion treatment), and structural components of drilling equipment.
2. Chemical equipment: used as a support for chemical reaction vessels, pipeline supports, or equipment frames in corrosive environments (corrosion-resistant materials such as stainless steel should be selected).
3. Power facilities: equipment brackets, cable trays, internal structural components of transmission towers, etc. in substations.
4、 Agriculture and Animal Husbandry
1. Agricultural greenhouse: As the skeleton of vegetable and flower greenhouses, it has the characteristics of high strength, strong wind and snow resistance, and is not easy to rust (galvanized square tube).
2. Breeding facilities: such as fences, feed conveying equipment brackets, and breeding pool frames for livestock and poultry farms.
3. Agricultural machinery: the body frame or component support structure of tractors and harvesters.
5、 Transportation and Logistics
1. Logistics equipment: shelves (such as storage shelves, supermarket shelves), container frames, freight vehicle carriage frames (such as truck guardrails, box truck frames).
2. Transportation facilities: highway guardrails, bridge crash barriers, traffic signal pole brackets, highway noise barrier frames, etc.
6、 Light Industry and Daily Necessities
1. Furniture manufacturing: Used for table and chair frames, wardrobe racks, shelves, etc., especially in wrought iron furniture or industrial style furniture, the sturdy lines of square pipes meet the design requirements.
2. Fitness equipment: such as treadmill frames, basketball hoop supports, gym equipment stands, etc., must meet the requirements of load-bearing capacity and durability.
3. Home decoration: Indoor partitions, curtain rod brackets, flower racks, drying racks, etc., some scenes may use stainless steel square tubes to enhance aesthetics.
7、 Other industries
1. Sports and entertainment: Stand support for sports venues, framework construction for large stages, amusement facilities (such as roller coaster track supports), etc.
2. Environmental protection equipment: brackets for sewage treatment equipment, structural components for exhaust gas treatment devices, etc.
3. Military and aerospace: Some special specifications of square tubes are used for lightweight structures of military equipment or auxiliary support components of spacecraft (requiring special materials such as high-strength aluminum alloy).
