Telescoping Rectangular Tubing

• High-precision telescoping fit: Engineered for tight nesting with minimal play-ensures smooth sliding and stable positioning in adjustable applications.
• Durable aluminum alloy construction: Made from robust alloys such as 6063-T5 or 6061-T6, offering excellent strength-to-weight ratio and corrosion resistance.
• Versatile dimension options: Available in multiple rectangular cross-section sizes, supporting versatile telescoping ranges for different load requirements.
• Customizable wall thickness and length: Supports wall thickness from thin to heavy-duty and lengths up to 6 meters or cut-to-length for project flexibility.
• Surface finish flexibility: Mill finish standard, with options for anodizing, powder coating, brushing, or custom RAL colors to suit visual and environmental demands.
• Strong structural performance: Maintains rigidity and structural integrity even under dynamic extension and compression loads.
• Wide industrial applicability: Ideal for retractable supports, adjustable frames, sliding mechanisms in equipment, vehicles, and furniture.

• Alloy Material: 6063-T5, 6061-T6, 6005A-T6 or custom alloy types
• Cross-section Sizes: Various inner and outer rectangular profiles to create multi-stage telescoping assemblies
• Wall Thickness: from 1 mm to 5 mm or customer defined range
• Length Options: Standard 3 m, 3.66 m, up to 6 m, or cut-to-order
• Surface Treatment: Mill finish, anodized, powder-coated, brushed, colored
• Fit Tolerance: Precision machining to ensure minimal clearance for smooth sliding
• Deep Processing: CNC cutting, drilling, punching, bending, assembly ready
