Vehicle Washdown Gantries, UK

Low Maintenance GRP Access Structures for Hazardous Environments | Case Study

Project: Vehicle Washdown Gantries, Newport Pagnell, UK

Client: Local Government

Throughout the UK winter, fleets of gritters are on permanent stand-by to undertake precautionary salting at a moment’s notice to keep Britain moving. Dura Composites high-performance GRP Access Structures are playing a crucial role in keeping these vehicles operational and well-maintained. Recently supplied projects include a range of gritter lorry washdown gantries which have been designed to accommodate multiple vehicles at once so they can be easily cleaned, refilled and maintained between winter journeys.

Whilst modern day gritting procedures use a combination of rock salt or white marine salt and an anti-caking agent, the chloride released still has a corrosive impact on steel, aluminium and concrete which can lead to slippery and unsafe walking surfaces and equipment access areas. By contrast, the non-metallic Glass Reinforced Polymer material which Dura Composites structures are fabricated from is resistant to a wide range of chemicals and has an expected design life in excess of 60 years. Durable and low-maintenance, it is also up to 80% lighter than steel, making it more cost-effective to transport and install.

Cost-effective, practical and safe, Dura Composites fabrications are constructed from our market leading d2 E23 Grade Dura Profile sections and open mesh anti-slip Dura Grating panels. In this project, a bespoke design was created by our in-house CAD team, meaning that each structure could accommodate several vehicles at once, enhancing operational efficiency and improving worker safety.

Chris Tate, Fabrications Commercial Manager at Dura Composites said:

Supporting the workforce at each location required safe height and frequent access to wash down vehicles using high-pressure washers. The steel gantries that had traditionally been used by the client had become incredibly slippery when wet and whilst the salt is highly effective, it has a corrosive effect on the steelwork. This means that the gantry structures have to be regularly inspected and maintained, which has a huge financial impact on site operation companies.


By choosing Dura Composites, our client was able to benefit from low maintenance fully fabricated GRP structures with warm-to-the-touch surfaces, that are non-sparking, non-corrosive, non-conductive and will never need painting, staining or galvanising. When combined with the walking surface and stair treads made from GRP Dura Grating it is the ideal anti-slip solution for hazardous industrial environments.

Unlocking the Power of Composites™ for the Highways Sector

Spreading salt (also known as grit) makes roads and pavements safer in freezing conditions by preventing ice and is generally distributed by lorry on major routes. In hazardous environments where slippery water and corrosive salts are frequently present, Dura Composites’ advanced composite materials offer vast benefits versus traditional metals such as steel. Dura Composites GRP has a superb strength to weight ratio, is lightweight non-corrosive, non-conductive and a ensures a low maintenance lifecycle and safe access for workers and maintenance personnel. We are well-equipped to supply repeat orders for standard fabrications and maintain large stocks in order to meet urgent project delivery times.
