Profiled Aluminum Square Tubes: The All-Round Material for Modern Architectural Decoration

Profiled aluminum square tubes are long strip-shaped decorative profiles made from high-purity aluminum alloy through the supergravity extrusion

molding process. They boast excellent hardness, straightness, and deformation resistance.

Core Characteristics:

• Lightweight material: Low density reduces building load-bearing pressure, facilitating transportation and installation.
•  
• Superior strength: Hardness and straightness far exceed ordinary aluminum square tubes, with stable structure and no easy deformation.
•  
• Wind and earthquake resistance: Special groove design enables firm connection with customized components, suitable for high-rise buildings and outdoor environments.
•  
• Fire safety: Class A non-combustible material, high temperature resistant, with no fire hazards.
•  
• Strong weather resistance: A natural oxide film forms on the surface, resisting acid-base corrosion and rust, with a service life of 15-20 years.
•  

2. Specification Parameters (Unit: mm)

Standard specification range:

• Bottom width: 20-400 (common: 50, 80, 100, 150)
•  
• Height: 20-600 (common: 50, 100, 200)
•  
• Wall thickness: 0.4-3.5 (0.6-1.2 recommended for indoor use, ≥1.5 for outdoor use)
•  
• Special specifications: Up to 300×150×3.5mm, meeting the needs of large-scale projects.
•  

III. Surface Treatment Processes and Effects

Profiled aluminum square tubes offer diverse surface treatments to meet different design style requirements:

1. Powder coating: Rich colors (over 60 standard colors), strong weather resistance, no easy fading.
2.  
3. Fluorocarbon coating: Preferred for outdoor use, UV and acid-base resistant, with a color retention period of over 10 years.
4.  
5. Wood grain transfer printing: Simulates natural wood texture, combining the warmth of wood with the durability of metal.
6.  
7. Stone/marble grain: Enhances spatial luxury, suitable for high-end venues.
8.  
9. Anodizing: Forms a natural oxide film, with high hardness and wear resistance.
10.  
11. Electroplating treatment: Presents a metallic mirror effect, enhancing spatial grandeur.

VI. Design and Installation Key Points

1. Selection Guide

Choose based on application scenarios:

• Indoor ceilings: Select U-shaped or straight aluminum square tubes with a thickness of 0.6-1.2mm.
•  
• Outdoor curtain walls: Prioritize profiled aluminum square tubes with a thickness of ≥1.5mm and fluorocarbon coating.
•  
• Humid environments: U-shaped aluminum square tubes + mildew-proof treatment to ensure long-term performance.
•  
• Large spaces: Curved/wavy shapes to solve acoustic problems and create visual impact.

2. Overview of Installation Steps

1. Surveying and setting out: Determine installation positions and keel spacing (30-40cm recommended).
2.  
3. Installing keels: Fix the light steel keel system to ensure levelness.
4.  
5. Installing hangers: Fix special hangers at both ends of aluminum square tubes.
6.  
7. Keel connection: Connect aluminum square tubes to keels using screws and customized components.
8.  
9. Adjusting spacing: Ensure uniform spacing between square tubes for consistent visual effect.

3. Practical Design Suggestions

• Commercial spaces: Control spacing at 60-80mm to enhance spatial transparency.
•  
• Residential spaces: Spacing of 80-100mm to create a comfortable atmosphere.
•  
• Floor height optimization: Narrow strips (30mm) are suitable for spaces with floor height ≤3m.
•  
• Acoustic needs: Perforated aluminum square tubes + sound-absorbing cotton, with a noise reduction coefficient of up to 0.7 or higher.
