Aluminium T-slot extrusion is the backbone of modular industrial infrastructure. Manufactured by pushing aluminium alloy billets through precision dies, these profiles feature continuous T-shaped channels along their length that accept standardised nuts, bolts, and brackets without drilling or welding.
Plant engineers rely on them for machine frames, conveyor support, workstation tables, equipment guards, and structural enclosures. The combination of high strength-to-weight ratio, corrosion resistance, and infinite reconfigurability makes T-slot the go-to choice over steel square tube in most non-extreme-load scenarios.
Common slot standards: 5mm, 6mm, 8mm, 10mm, 11mm (Unistrut 41mm). Series: 20, 30, 40, 45, 80 (profile face dimension in mm).
