We have a wealth of experience in the manufacture and supply of Trench and Access covers – both for new constructions and refurbishment applications. Let us help you Unlock the Power of Composites with a low maintenance, durable and simple to install composite Glass Reinforced Polymer (GRP) alternative to heavy & cumbersome steel or concrete covers.
Our trench and trough covers are designed for maximum versatility and work with both precast flat top concrete troughs as well as with precast concrete troughs with a factory formed recess which enable a flush fitting with the floor surface. From open mesh to solid top lids (or a combination of both), Dura Composites has an unrivalled selection of pedestrian and vehicle rated covers to meet your specific project needs.
With an innovative design that can include either manual lifting eyes or mechanical lifting arms, our trench cover lids can meet the needs for straight sections, curved sections, right angles and Ts and have an excellent strength to weight ratio. The lightweight nature of the covers mean routine inspections and repairs can be made easily, by simply removing the appropriate covers.
Our trench cover products have additional scope for use within overlay crossing points and cable pits. Our experienced team can advise on a range of standard and bespoke scenarios and can attend site on request for pre-start project consultations. We also offer 3D laser scanning and drone surveys for areas which are difficult to inspect or which have access restrictions.
3D Model: 1250mm Trough with Dura Slab 100mm Lid
A comprehensive range of pedestrian and vehicle-rated GRP covers in stock and ready for immediate dispatch
Our 50mm Rect HD & 53mm Rect HD products are the lightest, most efficient BS EN 124 covers at the standard 600mm span
d² Dura Grating and Dura Slab feature an industry-leading Class B fire rating (BS EN 13501-1), ideal for fire-critical projects
Our range of trench covers include both Moulded Lids for pedestrian loading and Pultruded Lids for vehicular loading – offering lightweight, high-strength solutions with various load ratings and cost-effective benefits.
Achieves an industry-leading Class B fire rating in accordance with the BS EN 13501-1 standard, making it suitable for a range of trench cover project installations where fire safety is an important consideration.
We offer Standard Mesh, Mini Mesh and Micro Mesh variants to suit specific project needs. The latest addition to the range is our Rectangular Mesh product, which meets the needs of narrow trench spans with maximum efficiency.
d² Dura Grating Solid Top is a great choice for situations where easy access is needed, but no daily light transmittance, drainage or visual inspection of the area underneath the grating is required. The gritted, anti-slip properties and rigorously tested solid surface of d² Dura Grating Solid Top is easier to clean compared with other types of open mesh grating, as there are no open spaces for debris to accumulate.
As an alternative to our moulded grating panels, we also offer pultruded GRP grating in various structural shapes, including I-Beam, T-Beam and Flat Beam.
The I-Beam grating has an I-shaped cross-section with flanges on either side of a central web, the T-Beam has a T-shaped cross-section with a central web and flanges on either side that extend beyond the width of the web to provide additional lateral stiffness, and the Flat Beam provides a smooth and flat surface that is ideal for pedestrian areas and areas which require additional drainage.
Each variant uses different shapes and sizes of bearing bars, providing excellent bi-directional strength and stiffness properties. The choice of which to use will depend on the specific requirements of your project, including the load-bearing requirements and overall aesthetics.
We are experts in the design, manufacture and supply of trench and access covers and heavy-duty floor slabs. Our Glass Reinforced Polymer (GRP) Dura Slab panels offer a low maintenance, durable and simple to install composite alternative to heavy & cumbersome steel or concrete covers.
With an innovative design that can include either manual lifting eyes or mechanical lifting arms, Dura Slab has an excellent strength to weight ratio. When used as trench or gully covers, its lightweight nature means routine inspections or cabling or other equipment can be made easily.
We offer a range of compatible accessories to complete your Trough Cover solution. Many accessories are available from stock, but some are custom manufactured to order, so please ensure you advise us of any accessory requirements at the earliest possible stage.
