Triangular tube
Key Design Features:
1. Optimized Triangular Geometry
Superior Torsional Rigidity – Triangular profile provides 30-40% greater resistance to twisting compared to round tubes of equivalent weight
Multi-Directional Bending Strength – Three distinct moment of inertia axes ensure uniform performance under complex loading conditions
Anti-Rotation Design – Flat surfaces prevent unwanted rotation during assembly and operation, eliminating the need for additional locking mechanisms
Space-Efficient Stacking – Geometric profile enables compact nesting and reduced storage/transport footprint
2. Precision Manufacturing Process
CNC Roll-Forming or Extrusion Technology – Automated forming ensures consistent wall thickness (±0.1mm) and precise angular tolerances (±0.5°)
High-Strength Materials – Manufactured from ST37, ST52, Q345 carbon steel, or 6061-T6/6063-T5 aluminum alloys
Seamless or Welded Construction – Options include DOM seamless tubing, ERW welded tube, or seamless extruded aluminum with complete structural integrity
Sharp or Rounded Corners – Available with precise 90° angles or radiused corners (R2-R10) based on application requirements
3. Superior Mechanical Properties
Wall Thickness Range – 1.5mm to 8.0mm customizable to structural and load requirements
High Yield Strength – 235-355 MPa for steel, 240-276 MPa for aluminum standard variants
Excellent Buckling Resistance – Triangular geometry provides superior resistance to local and global buckling under compression
Operating Temperature Range – -50°C to +150°C for steel, -40°C to +100°C for aluminum variants
4. Application-Specific Engineering
Structural Frameworks – Ideal for machine bases, robot arms, conveyor systems, and precision equipment frames
Agricultural Machinery – Used in tractor roll-over protection structures (ROPS), implement frames, and harvesting equipment
Construction Equipment – Perfect for scaffolding systems, support braces, and lightweight structural elements
Automotive & Transportation – Custom chassis components, battery enclosures for EVs, and cargo management systems
Renewable Energy – Solar panel mounting rails and wind turbine internal structures
5. Versatile Configuration Options
Equilateral Triangle Profile – Standard 60° angles for uniform multi-directional strength
Isosceles Triangle Profile – Custom apex angles (30°-90°) for directional strength optimization
Tapered or Variable Section – Gradual cross-section changes along length for optimized weight distribution
End Treatment Options – Miter-cut, notched, drilled, or welded end preparations available
Pre-Assembly Services – Precision cutting, hole patterns, and bracket welding included
