For light wells, channel covers and inspection openings where a closed, walkable surface is required, our GRP grating Closed offers the ideal solution.
The completely closed, sanded top surface reliably prevents dirt, water and leaves from penetrating and remains permanently rust-free and maintenance-free thanks to the GRP construction. Whether as a manhole cover, inspection cover or walkable platform surface. The Closed convinces wherever a flat, safe cover is required.

formavit® fiberglass reinforced plastic products are inherently corrosion-resistant, extremely weather- and chemical-resistant, and electrically insulating.
This means for you: easier handling during assembly and a completely maintenance-free end result – whether in heavy industry or for a private construction project.
Custom-fit GRP solutions from South Hesse - manufactured, tested, ready for dispatch.
Cutting and processing are carried out on-site according to clear standards. This ensures you receive clean edges, reliable dimensions, and predictable delivery times.
To make your selection as easy as possible, we have categorized our GRP gratings for you according to typical areas of application:
Tip: How much a grating can withstand depends not only on its height but also on how far apart the support points of your substructure (the span) are. If you are unsure, simply use our contact form or request a personalized quote – we will be happy to advise you on your project!
For open gratings, it is best to use our special stainless steel grating clamps (V2A/V4A). These grip perfectly into the 38x38 mm mesh and fix the grating rust-free and storm-proof to the substructure.
If you want to install our closed GRP floor plates or stair treads, we recommend our weather-resistant 2K epoxy adhesive for a bomb-proof hold without drilling – alternatively, these can also be conventionally screwed.
Yes, absolutely! Glass-reinforced plastic (GRP) can be worked with similarly to hardwood.
For on-site adjustments, a standard angle grinder with a diamond cutting disc or a jigsaw with a carbide blade is sufficient.
If you want to save yourself the work on the construction site: simply use our individual cutting service directly from South Hesse! We deliver all gratings and plates ready for installation.
We produce your custom cuts at our location in Southern Hesse using state-of-the-art special saws (diamond cutting discs) to ensure particularly clean cut edges.
To ensure your GRP products arrive quickly and undamaged, we select the optimal and most cost-effective shipping method for you based on size and weight:
Important for your planning: For freight deliveries, our logistics partner usually notifies you of the delivery in advance via email or phone. This allows you to perfectly plan for goods receipt at your delivery address or construction site.
