Extruded Aluminum Tube - Round Aluminium Pipe in Thin and Thick Wall for Welding Fabrication
Extruded Aluminum Round Tube for Welding and Fabrication
This extruded aluminum tube is a round aluminium pipe made by hot extrusion, so wall thickness, outer diameter and straightness stay consistent from the first length to the last. The clean surface and uniform round section make it easy to weld to plates, brackets and other tube sections, and it is supplied in thin wall for light frames and thick wall for load-bearing work.
Thin Wall and Thick Wall Options
Wall thickness drives weight, stiffness and how the tube behaves under welding heat. Thin wall tubing keeps fabricated assemblies light and suits decorative frames, guards, handrails and light shelving. Thick wall aluminium pipe carries more load and resists bending and distortion, suiting structural frames, machine guards, support legs and welded bases. Both come from the same round extrusion family, so one project can mix thin and thick sections and keep a consistent look and finish.
Material and Temper
The tube is made from extrusion-grade aluminium that balances formability, weldability and strength. Alloy and temper are selected to suit the job: softer tempers bend and form more easily, while harder tempers hold their shape in structural use. Tell us the working load, welding method and environment and we will match the alloy and temper to the part.
Welding and Fabrication
Round extruded tube is one of the easiest aluminium sections to fabricate. It can be cut, mitred, drilled, tapped, notched and welded with standard aluminium processes, and it takes bends and sweeps without collapsing when the wall is heavy enough. Straight cut ends reduce fit-up time, and a uniform wall means the weld pool behaves the same along the whole joint.
Dimensions and Surface Finish
Outer diameter, wall thickness and length are specified per order, supplied in stock lengths for cutting in your own workshop or cut to a finished length ready for the jig. Tube is usually mill finish, the untreated extruded surface and the natural choice when the part will be welded or painted afterwards; where a bright or coloured surface is wanted, it can be anodized instead.
Typical Applications
- Welded frames, gates, railings and handrails
- Machine guards, covers and equipment frames
- Shelving, racking and display structures
- Support legs, braces and load-bearing members
- Bicycle racks, trolleys and utility carriers
How to Specify Your Tube
- Give the outer diameter and wall thickness you need.
- State the length, stock or cut to size, and the quantity.
- Confirm the alloy and temper, or describe the load and environment.
- Say whether the tube stays mill finish or will be anodized.
- Note any welding, bending or threading that follows.
Send us your drawing and we will confirm the round extruded aluminium tube for your welding work.
