It offers a high strength‑to‑weight ratio, is lightweight to handle, and has good corrosion resistance. These traits make it suitable for both indoor and outdoor use with relatively low maintenance.

Common profiles include square hollow sections (SHS), rectangular hollow sections (RHS), and circular hollow sections (CHS). They come in a range of dimensions and wall thicknesses to fit different loads and spans.

Use a metal cutting saw with a fine‑tooth aluminium blade, support the piece, and cut steadily. Deburr edges with a file or deburring tool, and wear appropriate eye protection and gloves.

Welding is typically performed with TIG or MIG processes. Use the correct filler alloy (for example 4043 or 5356), clean the oxide layer before welding, and follow standard aluminium welding practices for clean, strong joints.

Yes. Aluminium’s natural oxide layer provides corrosion resistance, making it suitable for outdoor use. For enhanced durability, finishes like anodizing or protective coatings can be applied.

They’re well suited for building lightweight frames, supports, machinery frames, shelving, furniture frames, and other fabrication projects where a strong but light profile is beneficial.

Aluminium is lighter and more corrosion-resistant than steel, offering good stiffness-to-weight. It’s typically more expensive than PVC and steel for the same cross‑section, but easier to machine and assemble in many DIY and fabrication contexts.

Consider mechanical connectors like brackets, gussets, and end caps, or joining by welding for stronger connections. Ensure joints are properly aligned and supported during assembly.

Base your choice on load requirements, span, and desired deflection. For structural or load‑bearing uses, start with standard profiles and consult fabrication guidelines or a professional if in doubt.
