The hardhat for your ironwork Armadillo gully grate protector shellDesigned to enhance the longevity and performance of gully gratings in demanding environments. Engineered with durability in mind, these protective shells help to safeguard against wear and tear caused by heavy traffic, reducing maintenance needs and extending service life. ![]() Install once and protect, not twice and regret![]() It's a common issue that ironwork intended for vehicles with pneumatic tyres can become damaged by heavy plant during a construction project. Working with customers across the country we have developed a cost effective and easy to use solution to this age old problem. Manhole covers and gully grates are often installed during the early phases of a construction project. During this phase ironwork is exposed to extreme loads from heavy plant including, tracked vehicles, forklift prongs, digger buckets and more. Cover and gratings installed in these situations were never designed to accommodate these scenarios. This can result in premature failure and additional costs in materials and labour to put them right before handover. In addition, gully grates can often become clogged with silt and debris which can cause severe issues for the drainage system and the water course. This can result in high cleaning and maintenance costs, residual issues from long-term debris ingress and potentially significant fines. Armadillo is tough...

Promoting responsibility with Britain's waterways
The Sea Starts Here
We're promoting awareness of a simple but important issue on our most popular Tristar D400 gully gratings. Did you know that waste disposed of down gullies, whether at a roadside or pedestrianised area, can end up in the watercourse. This includes rivers, brooks, becks, ditches, leats and culverts. Ultimately, it has the potential to reach the sea, meaning the sea often really does start here.
In collaboration with a long-standing house building client, we've taken the notable step to include "The Sea Starts Here" as a message on our highest selling Tristar gully gratings. The message serves as a poignant reminder that our actions on land reverberate to our oceans.
