Australian Standards
All rag bolts are designed using our computerised engineering program and manufactured to Australian Standards. They are manufactured with either mild or high tensile steel, with hot-dip galvanising applied to withstand corrosion and improve long-term durability.
These bolts are typically supplied in a “U” formation for general use, with diameters ranging from M12 to M36. For larger bolt assemblies, such as M30, M33, and M36, an “L” formation is used to provide additional stability. Each bolt is engineered to suit the pole application, ensuring proper fit and strength for both standard and custom pole installations.
Specifications
Each rag bolt assembly includes:
- A rag bolt former-template
- Two nuts and two washers per thread
- Options for prefabricated welded bolt cages in a range of sizes
These components are designed to hold the rag bolts in place during the concrete pour, maintaining the correct alignment for pole erection. By maintaining precision in the concrete foundation, the pole can be securely and accurately positioned once installation takes place.
We also manufacture custom bolt cages and assemblies for:
- Shallow concrete foundations
- Building slab installations
- Above-ground mobile foundations
All assemblies are manufactured to meet the engineered foundation design and specific site conditions.
For project efficiency, rag bolt assemblies can be delivered prior to pole delivery, giving you ample time for foundation curing before column installation. This process helps streamline project timelines and reduces installation delays.
If required, we can recommend experienced installation partners to manage the foundation setup. Please see our procedures section for more details on rag bolt foundations and concrete procedures.
Screwpile
As an alternative to traditional concrete foundations, screwpiles offer a fast, practical solution. These screw-in steel piles can be installed and ready to accept the pole within 30 minutes, eliminating the wait time for concrete to cure.
Each screwpile foundation can be supplied with:
- Baseplates
- Cable entry slots for easy cable access and connection
This method is ideal for temporary installations, time-critical projects, and sites with difficult ground conditions such as rock. Screwpiles offer excellent stability and can be used across both urban and regional applications.
