Renewable Energy

Naturally safe and reliable

Renewable energy has a vast growth potential. Plants for alternative energy generation shall be trouble-free at long sight and must therefore be maintained on a regular basis. For underfoot safety in these plants, Graepel metal profile gratings as stairways, landings, catwalks and platforms can be used.

Our safety gratings are custom made solutions which are absolutely reliable in all weather. Special perforations provide slip resistance and drainage allowing safe access of the plant also when heavy contaminations are present. Thanks to high-quality gratings and an excellent level of rigidity, large span widths are possible without complicated frame structures.

Metal profile gratings can be supplied in the materials below: raw steel, hot-dip galvanized steel, pre-galvanized steel, pickled stainless steel and aluminum. The material thickness depends on the desired load capacity. On request, other surface finishes are available.

Special attention must be given to the safety in biogas plants because large amounts of combustible gas are produced and processed. Our metal profile gratings contribute to this safety. Stairways, platforms and walkways on fermenters as well as walking surfaces on machine houses allow the operating personnel to safely access the plants in all weather conditions. Slip resistance and drainage are achieved by embossed and debossed perforations. Hot-dip galvanized steel gratings are also corrosion-resistant, long-lasting and low-maintenance.
