About GAP Engineering

 

GAP Engineering T Slot Aluminium Profiles and accessories

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
How GAP Engineering Supports You

We’re more than just a supplier — we’re your modular build partner. You can order:

  • Aluminium profiles by the bar (full or cut to size)

  • Connectors, joints, and accessories

  • Pre-cut, drilled, and tapped components to your specs

  • Fully assembled systems built to your design

Whether you’re building a prototype, outfitting a workshop, or scaling industrial production, we’re here to help — no project is too big or too small.
