Kedla Aluminium Rectangular Tube 40 x 20 mm 2.5 m

Maximum Strength and Slim Design in a Rectangular Profile

 

The Kedla Aluminium Rectangular Tube (Profile EX-R71) is a highly efficient structural profile designed for projects requiring stiffness along one axis and a narrow, clean aesthetic on the other. Manufactured by Kedla and typically supplied through Castor & Ladder Supply, this tube features sides of 25.4 mm (the height) and 12.7 mm (the width) with a strong 1.22 mm wall thickness. When oriented vertically (25.4mm tall), it provides significantly higher bending strength than a square tube of similar material volume, making it perfect for vertical supports and modern frames.

Provided in a convenient 2.5-metre length, this tube minimizes waste while offering ease of handling. Crafted from high-quality aluminium (Alloy 6063-T6), it boasts excellent natural corrosion resistance, ensuring its durability for long-term use in exposed interior or exterior environments. It is competitively priced and highly valued for custom shopfitting, architectural framing, and secure mounting solutions.

Top 3 Frequently Asked Questions (FAQs)

 

1. What is the main advantage of a rectangular tube over a square tube?

   • Rectangular tube is designed to resist bending most efficiently in one direction (the taller dimension). For example, a 25.4mm x 12.7mm tube is significantly stiffer against vertical loads than a 19.05mm x 19.05mm square tube of the same weight.

2. What are the Inner Dimensions (ID) of the tube?

   • The Inner Dimensions (ID) are calculated by subtracting twice the Wall Thickness from each side. This results in 22.96 mm x 10.26 mm.

3. How can I connect this rectangular tube at 90-degree corners?

   • For the strongest result, weld the mitred corners. For non-permanent assembly, use proprietary internal or external rectangular tube joiners or corner brackets.
