The hardware connecting a high mast pole to its foundation carries the entire structural and wind load of the pole above it — this is not a component to under-specify. Here's what's involved.
A cage of high-tensile anchor bolts is fabricated and set into the foundation formwork using a template that precisely matches the pole's base flange — even a small misalignment here can make pole erection difficult or compromise the load path.
The pole's base plate distributes its load onto the anchor bolts and foundation. Plate thickness and bolt circle diameter are engineered to the pole's design wind load, not standardized across all pole heights.
After the pole is set, the gap between base plate and foundation is non-shrink grouted and leveled — getting this step wrong is a common cause of long-term pole tilt or vibration issues that only show up months after installation.
All anchor bolts and hardware come with mill test certificates confirming the steel grade, which is typically required documentation for government tender handover and structural audits.
Do you supply foundation hardware separately for a project we're installing ourselves?
Yes, we can supply anchor bolt cages, base plates, and templates as a standalone item, engineered to your pole's specification, with mill test certificates included.
What happens if the anchor bolt template doesn't match the pole on delivery?
This is exactly why we supply pole and foundation hardware as a matched set wherever possible — when hardware is sourced separately from a different pole supplier, mismatch is a real and common risk.
