Introduction
Aluminium extrusions are fundamental components used in countless construction and industrial applications. From window frames to structural supports, they provide strength, versatility, and aesthetic appeal.
What Are Aluminium Extrusions?
Aluminium extrusion is a manufacturing process where aluminium alloy is forced through a die with a specific cross-sectional profile, creating long, continuous pieces with consistent shapes.
The Extrusion Process
The process involves heating aluminium billets to 400-500C, forcing the heated aluminium through a steel die, cooling, stretching, cutting to length, and ageing for strength.
Types of Profiles
Standard Profiles
Angles, channels, tubes, bars, and T-sections used in general construction and manufacturing.
