In conclusion, the maximum out diameter of the aluminium scaffold tube is 48.8mm, and the minimum out diameter of the alloy scaffolding pipe is 47.8mm.
The maximum thickness of the alloy scaffold tube is 5.03m, and the minimum of the alloy scaffold tube is 3.91m.
Aluminium scaffold tube length is normally 6m and 6.4(21′). But can cut to any lengths needed. Length tolerance is ±6mm
For the weight of the aluminium scaffolding tube, the single tube max. reduction 7.5%. While weight for quantities of 150m and over is ±5%

Why Is Tubular Aluminium Used In Scaffolding?
9 Advantages of Tubular Aluminium Scaffolding
- Aluminium Tubular Scaffolding is only 1.67 KG/m. It is 2.5 times lighter than steel tubular scaffolding.
- Tubular Aluminium Scaffolding Saves Half Labors and Half of the Erection Time For the Same Size Of Steel Tubular Scaffolding
- Tubular Aluminium Scaffolding Naturally Resistant to Corrosion and Need Less Maintenances Compared to Steel Tubular Scaffold
- Tubular Aluminum Scaffolding is Flexible to Adapt to Different Heights, Different Shapes and Configurations of Construction Compared to Other Types of Aluminium Scaffolding.
- Tubular Aluminium Scaffolding Can Repeat Use and Saving Cost In Long Term
- Aluminium Scaffold Tubes can withstand Harsh Conditions
- 6082 Aluminium makes the Scaffolding Tubes The Maximum Bearing to Weight Ratio
- Aluminium scaffold tubes with OD48.3mm standard diameter that are compatible with all types of scaffold couplers and fittings
- Tubular Aluminium Scaffolding Can be Any Length to Fit Veriaty Projects
Scaffold Fittings for Aluminium Tube Scaffolding
In aluminium tube scaffolding, scaffold fittings are the connectors and joints between aluminium tubes in vertical, horizontal and diagonal directions.
Aluminium scaffold tube clamps and fittings are steel scaffold couplers. The types of fittings for aluminium scaffold tubes include double scaffold couplers and swivel clamps.
Aluminium Scaffold Double Coupler
The double scaffold coupler fixes two scaffold aluminium tubes at 90 degrees (right angles). There are two types of scaffold double couplers for the aluminium scaffold tubes. One is the bolted double coupler, and the other type is the wedge-type double coupler.
Aluminium Scaffold Swivel Clamps
Swivel clamps fix scaffolding aluminium pipes and poles at any angle in 360 degrees. For swivel clamps, both bolted swivel clamps and swivel wedge clamps are both workable with the common aluminium scaffold tubes.
Key Takeaways
Aluminium scaffold tubes are made of 6082 aluminium, which has strong strength and is light in weight. They are OD48.3mm and fixed by normal standard scaffold fittings of double and swivel clamps in construction.
Aluminium scaffold tubes are commonly used in scaffolding for the reason of 9 important advantages. Using the alloy tubes saves costs in the long term.
