Built Like a Tank: A Pro's Guide to Heavy Duty Conduit

For some jobs, standard electrical conduit just won't survive. When you're wiring up a factory floor, running underground mains, or working in a corrosive coastal environment, you need to step up to the next level of protection. Heavy duty conduit is the no-compromise solution, engineered to provide the ultimate in mechanical strength and environmental resistance for your critical cabling.

At SCHNAP, our heavy duty conduit range is designed to tackle Australia’s toughest electrical installs, giving sparkies and contractors the confidence that their work is protected and built to last.

Choosing the Right Armour for Your Cables

The environment of your job site will determine the best material for maximum protection.

  • Hot Dip Galvanised Steel Conduit: The classic heavy-hitter. Renowned for its exceptional impact and crush resistance, galvanised steel conduit is the perfect choice for protecting wiring in workshops, factories, and any area with a high risk of mechanical damage.
  • 316 Stainless Steel Conduit: The ultimate choice for corrosion resistance. 316 stainless steel conduit is a must-have for food processing plants, chemical facilities, marine environments, and coastal areas where salt spray and harsh chemicals would destroy other materials.
  • Heavy-Duty UV-Stabilised PVC Conduit: The tough, non-corrosive workhorse for underground mains and exposed outdoor wiring. Unlike standard PVC, our heavy-duty conduit has a thicker wall for greater impact strength and is UV-stabilised to withstand the harsh Aussie sun for decades without becoming brittle.
  • Oil & Heat-Resistant Flexible Conduit: The ideal solution for the final connection to heavy machinery. This flexible conduit is specifically designed to protect wiring from heat, oils, coolants, and the constant vibration found on the factory floor.

A Size for Any Heavy-Duty Job

Our range covers all standard Australian conduit sizes, from 16mm right up to 63.5mm, available in lengths up to 6 metres, along with all the matching heavy-duty fittings you'll need.

Top Brands for Ultimate Protection

When your installation absolutely has to last, you need to use materials you can trust. We stock high-quality heavy duty conduit from leading brands that Aussie contractors rely on, including Tradepro and Repelec.
