Kedla Aluminium Round Tube 13,9 mm OD x 2.5 m: EX-R51 Profile Structural Strength, Medium-Duty Railing and Framing

The Structural Tube for Strength and Fine Fabrication

 

The Kedla Aluminium Round Tube (Profile EX-R51) is the medium-duty profile designed for projects requiring better structural support and stability than thin-walled tubing. Manufactured by Kedla and typically supplied through Castor & Ladder Supply, this tube maintains an easily integrated Outer Diameter (OD) of 12.7 mm (exactly 1/2 inch) but features a much more substantial 1.22 mm wall thickness. This thicker wall dramatically increases the tube's resistance to bending and denting, making it ideal for durable frames and secure fixtures.

Provided in a convenient 2.5-metre length, this tube is highly manageable for transport and allows for strong, continuous runs. Crafted from high-quality aluminium (Alloy 6063-T6), it boasts excellent natural corrosion resistance, ensuring its integrity for long-term use in exposed or damp exterior environments. It is competitively priced and highly valued for detailed fabrication where increased strength is a key requirement.

 

Key Features

 

• Manufacturer: Kedla (Supplier of the EX-R51 Profile).

• Supplier: Castor & Ladder Supply.

• Material: High-Quality Aluminium (Alloy 6063-T6).

• Dimensions:

  • Outer Diameter (OD): 12.7 mm (Exactly 1/2 inch).

  • Wall Thickness: 1.22 mm (Medium gauge).

  • Length: 2.5 metres (2500 mm).

• Enhanced Strength: The 1.22 mm wall offers significantly higher rigidity than the 0.7 mm wall tube (EX-R50).

 

Ideal For

 

• Structural Model Making: Building rigid, load-bearing frames for robotics, dioramas, or precision instruments.

• Medium-Duty Railings: Stronger infill sections, towel rails, or light barrier construction.

• Custom Fixtures: Creating durable mounting brackets, stand-offs, or small machine components.

• Outdoor Applications: Garden structures, trellises, or weather-exposed decorative elements.

 

Why You Will Love It

 

• Superior Durability: The thicker wall resists denting and buckling, maintaining its shape under more stress.

• Weldable: The 1.22 mm thickness is much easier to TIG or MIG weld than thinner gauges, offering better results for permanent structural joints.

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

• Seamless Finish: Provides a clean, professional aesthetic for exposed components.

Top 3 Frequently Asked Questions (FAQs)

 

1. How much stronger is the R51 tube compared to the R50 tube (0.7mm wall)?

   • The R51 tube is significantly stronger. The increase in wall thickness from 0.7 mm to 1.22 mm (nearly double) provides much greater bending stiffness and structural integrity for moderate loads.

2. What is the Inner Diameter (ID) of this 1.22 mm wall tube?

   • The Inner Diameter (ID) is calculated as Outer Diameter minus twice the Wall Thickness. Therefore, 12.7 mm minus (2 x 1.22 mm) equals 10.26 mm.

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

   • For the cleanest cut and best results, use a chop saw with a non-ferrous metal cutting blade. A fine-toothed hacksaw or a good-quality pipe cutter will also work effectively.
