What are the common specifications of aluminum square tubes?
This article provides a detailed introduction to the common specifications of aluminum square tubes, including cross-sectional dimensions, wall thickness, and length parameters. It also categorically lists the commonly used specifications of aluminum square tubes in fields such as construction and industry. At the same time, it explains the applicable scenarios and selection points of different specifications to help users quickly match their needs.
I. Basic Specification Parameters of Aluminum Square Tubes
The specifications of aluminum square tubes are mainly determined by three core parameters: cross-sectional dimensions (side length), wall thickness, and length. According to the national standard (GB/T 6892-2015 "Aluminum and Aluminum Alloy Extruded Profiles for General Industrial Use"), common specifications are as follows:
1. Cross-sectional dimensions:
- Small square tubes: 20mm×20mm, 25mm×25mm, 30mm×30mm
- Medium square tubes: 40mm×40mm, 50mm×50mm, 60mm×60mm
- Large square tubes: 80mm×80mm, 100mm×100mm, 120mm×120mm
2. Wall thickness range:
- Thin-walled tubes: 1.0mm - 2.0mm (suitable for light-load decoration)
- Standard-walled tubes: 2.5mm - 4.0mm (commonly used in building structures)
- Thick-walled tubes: 5.0mm - 8.0mm (used for load-bearing or industrial equipment)
3. Length:
The standard length is 6 meters, and non-standard lengths such as 3 meters, 4 meters, or 12 meters can also be customized according to requirements.
II. Specification Selection for Different Application Scenarios
Aluminum profiles are widely used in fields such as building curtain walls, mechanical manufacturing, and furniture. When selecting the specifications, factors such as load-bearing capacity and corrosion resistance should be considered:
1. Architectural Decoration:
- Recommended Specifications: 40mm×40mm×2.0mm, 50mm×50mm×2.5mm
- Characteristics: Lightweight and easy to process, suitable for ceilings, partitions, etc.
2. Industrial Framework:
- Recommended Specifications: 60mm×60mm×3.0mm, 80mm×80mm×4.0mm
- Characteristics: High strength and stability, used for equipment supports or conveyor line tracks.
3. Outdoor Facilities:
- Recommended Specifications: 30mm×30mm×1.5mm (surface requires anodized treatment)
- Characteristics: Strong weather resistance, suitable for guardrails, billboards, etc.
III. Special Specifications and Customization Requirements
Some industries require non-standard specifications, such as:
- Special-shaped square tubes: with rounded corners or beveled edges, commonly used in the furniture industry.
- Ultra-thick-walled tubes: with a wall thickness of over 10mm, used for the support of heavy machinery.
