50*100mm white twisted aluminum square tube profiles

Twisted aluminum square tubes are an innovative material in the field of modern architectural decoration. They perfectly combine the excellent performance of aluminum with unique twisted shapes, injecting new vitality into architectural design. From the "Red Ribbon" in Beijing to the Shanghai International Financial Center, twisted aluminum square tubes are reshaping contemporary architectural aesthetics with their light and flexible posture.

Core Characteristics:

• Lightweight: Aluminum alloy has a low density and light weight, facilitating transportation and installation.
•  
• High strength: The tensile strength of the 6061-T6 grade reaches 290-350MPa, far exceeding that of ordinary steel.
•  
• Excellent corrosion resistance: A natural oxide film forms on the surface, resisting acid and alkali erosion and making it suitable for outdoor use.
•  
• Unique three-dimensional effect: The twisted shape creates a sense of flow and spatial layering, adding a modern design touch to buildings.
•  
• Fire and moisture resistance: As a non-combustible material with superior moisture resistance, it is suitable for various building environments.
•  
• Good processability: It can be bent and twisted arbitrarily to realize designers' creative concepts.

II. Materials and Specifications

Main Material Options:

Common Specification Range:

•  
• Section size: Square (20×20mm~200×200mm), rectangular (10×20mm~200×400mm)
•  
• Wall thickness: 0.8-3.0mm (≥1.2mm is recommended for twisting processing to avoid excessive deformation)
•  
• Length: Standard 6 meters, customizable (up to 12 meters)
•  
• Twist parameters: Twist angle 30°-90°, torque (pitch) 100-500mm, adjustable according to design requirements

III. Processing Technology

1. Raw material preparation: Select 6061/6063 aluminum alloy ingots and conduct quality inspection.
2.  
3. Extrusion forming: Extrude into standard square tubes through special molds at a high temperature of 400-500℃.
4.  
5. Cooling and setting: Rapidly cool through air or water cooling systems to ensure dimensional accuracy.
6.  
7. Twisting processing (core process):
   •  
   • Cold twisting method: Use CNC twisting equipment to apply precise torque to square tubes at room temperature to form uniform spiral twists.
   •  
   • Hot twisting method: Locally heat the square tube to 200-300℃ to improve plasticity before twisting, suitable for complex shapes.
   •  
   • Stretching-bending combination: Stretch first, then bend, and finally twist to achieve three-dimensional complex deformation.
8.  
9. Surface treatment:
   •  
   • Fluorocarbon spraying: Two-coat one-bake/three-coat one-bake, with strong weather resistance and color retention for 10-20 years without fading.
   •  
   • Powder spraying: Low cost and rich color options.
   •  
   • Wood grain transfer printing: Simulates wood texture, suitable for retro or natural style designs.
