Aluminium scaffolding tubes are valued for their strength, light weight, and versatility in construction and industrial applications. When working with a standard 20 ft aluminium scaffolding tube, you may find it necessary to cut the tube to a custom length for a specific project or to fit unique site requirements.
Understanding 20 Ft Aluminium Scaffolding Tube
A 20 ft aluminium scaffolding tube is a hollow, extruded tube made from high-strength aluminium alloys, typically with an outside diameter of 48.3 mm and a wall thickness around 4.0–4.5 mm, conforming to international standards such as BS 1139-1.2 and EN 755-2. These tubes are widely used in scaffolding systems due to their excellent strength-to-weight ratio and corrosion resistance.
Key Features:
- Standard length: 20 feet (6.0 meters)
- Diameter: 48.3 mm (±0.5 mm)
- Wall thickness: 4.0–4.47 mm (±0.56 mm)
- Alloy: Commonly EN-AW6082-T6
- Application: Scaffolding, handrails, industrial structures
Aluminium scaffolding tubes are preferred for their lightness, making assembly and disassembly faster and safer compared to heavier steel tubes. Their corrosion resistance also makes them suitable for outdoor and marine environments.
Why Cut a 20 Ft Aluminium Scaffolding Tube?
There are several reasons you might need to cut a 20 ft aluminium scaffolding tube:

- Guillotine shear (for high-precision cuts)
- File or deburring tool
- Measuring tape and permanent marker
Safety Gear:
- Safety glasses or face shield
- Gloves (to protect from sharp edges)
- Hearing protection (if using power tools)
- Dust mask (if generating fine particles)
Preparation Steps:
1. Inspect the tube for dents, cracks, or defects before cutting.
2. Measure and mark the desired cut length accurately using a tape measure and marker.
3. Secure the tube firmly in a clamp or vise to prevent movement during cutting.
Step-by-Step Guide: How to Cut a 20 Ft Aluminium Scaffolding Tube
1. Measure and Mark
- Use a tape measure to determine the exact length needed.
- Mark the cut line clearly with a permanent marker or scribe.
- For a straight cut, use a square or wrap a sheet of paper around the tube to guide your mark.
2. Secure the Tube
- Place the tube in a sturdy clamp or vise.
- Ensure the tube is level and the marked line is visible and accessible.
- Support both ends of the tube to prevent sagging or vibration.
3. Select the Right Tool
- For most aluminium scaffold tubes, a fine-tooth hacksaw, band saw, or circular saw with an aluminium-rated blade is ideal.
- For high-precision cuts or larger volumes, use a guillotine shear or an automatic aluminium cutting machine.
4. Cutting
- Manual Sawing: Apply steady, even pressure. Let the teeth of the saw do the work.
- Power Sawing: Start the saw before contacting the tube. Guide the blade slowly along the marked line.
- Tube Cutter: Rotate the cutter around the tube, gradually tightening until the tube is severed.
5. Deburring and Finishing
- Use a file or deburring tool to smooth any sharp edges or burrs left by cutting.
- Inspect the cut end for squareness and smoothness.
- Wipe the tube clean to remove filings and dust.
Best Tools for Cutting Aluminium Scaffolding Tubes
Tool Type | Best For | Pros | Cons |
Fine-tooth hacksaw | Single/few cuts, small projects | Inexpensive, precise | Labor-intensive, slower |
Band saw | Multiple cuts, medium projects | Fast, clean cuts | Requires setup, less portable |
Circular saw (aluminium blade) | Fast, straight cuts, on-site use | Quick, widely available | Noisy, requires PPE |
Guillotine shear | High-precision, professional shops | Very clean, accurate cuts | Expensive, less portable |
Tube cutter (manual/ratcheting) | Clean, burr-free cuts | Easy to use, minimal burrs | Slower, best for smaller diameters |
Tip: Always use a blade or tool rated for aluminium to prevent binding or excessive wear.
Tips for a Clean, Accurate Cut
- Use sharp, undamaged blades for best results.
