General engineering services

Calbah’s ability to design, engineer and fabricate products to deliver solutions for its clients’ challenges result in a product development capability that is literally endless.

We have developed everything from sound proof enclosures, platforms and caged ladders to bridges, ducting and jib booms. Our complex engineering projects are found in tough environments such as mining, rail, oil and gas industries.

Calbah can work from your designs or develop them for you. Many clients actively use the partnership approach Calbah takes when developing engineering solutions to further enhance the specifications and effectiveness of their products.

Our engineering solutions extend to all metals including aluminium, stainless steel and various exotic alloys.

Once built, Calbah is able to offer expert onsite installation - so you can be sure of your product’s optimum performance.
