GRP grating (general polyester resin)
This type of grating is used for the construction of walkways, stairs, platforms, ventilation grids, fences, and in many other applications where a surface resistant to weathering, corrosion and wear is required. In fact, GRP composite offers excellent resistance to chemicals, making it suitable for use in aggressive environments where a conventional steel grating might degrade over time. GRP grating is also highly valued for its light weight and ease of installation and maintenance.
Composite gratings offer an optimal combination of strength, durability and lightness, making them ideal for a variety of industrial and architectural applications.
