Kedla Aluminium Square Tube 21 mm x 2.5 m: EX-R61 Profile Medium-Duty Framing and Rigid Structural Support

Sturdy Square Profile for Rigid Frames and Assemblies

 

The Kedla Aluminium Square Tube (Profile EX-R61) is a reliable, medium-sized profile designed for projects where high rigidity and clean lines are essential. Manufactured by Kedla and typically supplied through Castor & Ladder Supply, this tube features sides of 15.875 mm (exactly 5/8 inch) and a sturdy 1.22 mm wall thickness. The square shape provides superior resistance to twisting (torsional stiffness) compared to a round or flat bar, making it the preferred choice for stable frames, jigs, and fixtures.

Provided in a convenient 2.5-metre length, this tube is easy to handle and transport. 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 model making, bespoke furniture, and general medium-duty fabrication.

Why You Will Love It

 

• Increased Rigidity: The larger side length and square shape provide better strength and resistance to deflection than the smaller R60 profile.

• Easy to Join: The flat sides simplify the construction of 90-degree joints using welding, bolting, or specialized connectors.

• Weldable: The 1.22 mm wall thickness is suitable for TIG or MIG welding, allowing for strong, permanent joints.

• Corrosion Proof: Aluminium resists rust and moisture damage, ensuring long life indoors and out.

Top 3 Frequently Asked Questions (FAQs)

 

1. What is the Inner Dimension (ID) of the tube?

   • The Inner Dimension (ID) is calculated as Side Length minus twice the Wall Thickness. Therefore, 15.875 mm minus (2 x 1.22 mm) equals 13.435 mm.

2. How much stronger is this tube than the R60 (12.7mm) profile?

   • Due to the increase in side length from 12.7mm to 15.875mm, this tube offers significantly greater structural strength and is better suited for spanning wider distances.

3. What is the best way to cut this medium-gauge tube?

   • For the cleanest, straightest cuts, use a chop saw with a non-ferrous metal cutting blade. A fine-toothed hacksaw is also effective but requires careful alignment.
