About GAP Engineering
At GAP Engineering, we supply high-quality T-Slot Aluminium Extrusions and accessories to customers across Australia — empowering them to design and build faster, smarter, and more flexibly than ever before.
T-Slot Aluminium is a modular framing system, often described as an industrial-grade Meccano set. It’s engineered for versatility: the aluminum profiles are extruded with T-shaped slots that accept special nuts and fasteners, allowing you to easily join sections together, mount components, or add accessories — without welding, grinding, or painting.
How It Works
Our extrusions are made from durable, anodized 6063-T5 Aluminium — offering strength, corrosion resistance, and clean aesthetics. Here’s why builders love it:
Cut to Size: Easily cut profiles to your desired length.
Tap & Thread: Cores can be tapped to accept bolts for strong, clean connections.
Slot-Based Assembly: Use T-nuts and connectors that slide into the grooves — perfect for quick changes or modular upgrades.
No Welding Required: Build with just hand tools — no heat, sparks, or toxic fumes.
- No Surface Treatment Required: Because its already anodized all you need to do is install it
