Crocodile Traps

Crocodile traps
We've come a long way in crocodile-trapping technology in the Northern Territory; no more jumping out of boats, wrestling with crocs or capturing them in nets. Now, at Greville Fabrication, we can custom-make crocodile traps to catch even the largest of crocs.

Our crocodile traps are made tough to withstand hundreds of kilos of thrashing croc. We understand the need for crocodile management in the NT and as such create these traps designed for easy placement and removal.

Metal Forming

Metal forming
Have a project that's little bit different?

Talk to the team at Greville Fabrication for all your custom metal forming needs. We can shape, bend and create new unique products to suit your specs. If you have a product that doesn't quite work, we can modify it to suit your exact needs.

Trench Grates

Trench gates
Ideal for public areas, homes, businesses and industrial premises, trench grates are essential for the drainage of rain and wastewater during the Darwin intense wet season.

Our techs and welders manufacture both pre-made and custom-made trench grates. These grates can go around corners for optimal drainage and safety. Made to any size and weight rating, the patented design enables us to build a grate to any radius, speeding the flow of water within the trench and enabling diversions around plant and equipment, as well as water features and artwork. The ability to create curved corners makes clearing of trenches in flood processing and washdown bays much easier.

Grates can be made of steel, glavanised steel, aluminum or stainless.
