GRP (Glass Reinforced Polyester) is a composite material offering an exceptional combination of lightness, mechanical strength, and durability. It is distinguished by its high resistance to corrosion, chemicals, and extreme environmental conditions, making it ideal for a wide range of industrial applications. In addition, its design flexibility allows for the manufacture of custom structures, optimizing the performance and longevity of equipment.
GRP (Glass Reinforced Polyester) cannot be recycled in the same way as traditional plastics. Due to its composite composition—a polymer matrix reinforced with glass fibers—conventional mechanical recycling is difficult. However, there are specialized processes for recovering end-of-life materials, including energy recovery or grinding techniques and reuse in secondary applications (fillers, construction materials, etc.). In addition, research is underway to develop more sustainable recycling methods for composites. GCER remains attentive to these technological developments in order to integrate environmentally friendly solutions into its processes.

A grating is an openwork structure composed of mesh (often square or rectangular), used primarily as anti-slip flooring in industrial areas, walkways, platforms, or wet areas. It allows liquids to drain, provides ventilation, and offers good mechanical strength.
The grating is designed to : • Create safe walking surfaces. • Allow water or chemicals to drain away. • Offer good load-bearing capacity and corrosion resistance. • Maintain a non-slip surface in slippery environments.
GRP grating offers many advantages : • Excellent corrosion resistance : suitable for chemical, marine, or humid environments • Lightweight : easier to handle and install than traditional metal materials • High mechanical strength : withstands heavy loads while maintaining its shape • Non-slip surface : improves safety in walkways, even in wet conditions • Low maintenance : does not rust and does not require regular treatment • Extended service life : excellent durability even in extreme conditions • Electrical insulation : non-conductive material, ideal for environments with electrical hazards • UV and weather resistance : suitable for outdoor use
GRP (Glass Reinforced Polyester) gratings are a high-performance alternative to steel due to their light weight, corrosion resistance, and durability in aggressive environments (chemical, marine, humid, etc.). Unlike steel, they do not rust, require no anti-corrosion treatment, and need very little maintenance. Their non-slip surface improves user safety, and their low electrical conductivity makes them suitable for sensitive environments. They therefore offer a reliable, economical, and sustainable technical solution.
Our GRP (Glass Reinforced Polyester) gratings are frequently used in conjunction with other industrial equipment, such as metal platforms, to create integrated and optimized solutions. This combination ensures the safety, stability, and durability of installations, even in particularly demanding industrial environments.

An access hatch is a closure (often solid or partially openwork) that provides access to, or closure of, an opening such as a manhole, tank or inspection chamber etc. It can be hinged, removable or lockable depending on its intended use.
The access hatch is used to : • Close or secure an opening (manhole, technical room, tank, etc.). • Provide occasional access for maintenance, inspection, or cleaning. • Ensure watertightness, safety, or protection against intrusion.
In some cases, reinforced grating can be used as a cover or openwork hatch, particularly when ventilation or drainage is required. However, for watertight or secure closure functions, a specific hatch is recommended.
Although often found in the same environments, gratings and access hatches have very distinct uses and characteristics : • Main function : - The grating is an openwork surface designed to allow people or fluids to pass through. - The access hatch is mainly used to close or provide access to an opening. • Structure : - The grating is generally made of openwork mesh. - The access hatch is solid or semi-openwork, depending on the sealing or safety requirements. • Installation : - The grating is fixed to the floor and can be installed in a raised or suspended position. - The access hatch is placed over an opening and is often movable (removable or hinged). • Access : - The grating is not designed to be easily removed, as it is an integral part of the passageway structure. - The access hatch is designed to be easily opened or removed to allow direct access. • Example of use : - Grating is used for walkways, raised floors, or traffic areas, etc. - Access hatches are used for manholes, inspection hatches, or tank access, etc.
The standard dimensions of GRP (Glass Reinforced Polyester) access hatches vary depending on the model : • P38 – Thickness 41 mm : 1220 x 3660 mm • P30 – Thickness 33 mm : 1000 x 4000 mm • P40 – Thickness 41 mm : 1000 x 4000 mm Custom sizes can be manufactured to meet specific customer requirements.
