Our product is a composite made of polyester and fiberglass tailored for BMC products. Additional materials are included to enhance homogeneity, resist shrinkage, corrosion, and wear, and provide the required strength. It is engineered to withstand high loads. BMC products contain no iron at all, and the high tensile strength typically provided by iron is compensated by fiberglass, which has proven to be highly efficient and sometimes superior to iron. GRP covers are available in various colors according to our clients’ preferences and project requirements, altering the overall design of the site. They also offer exceptional resistance to chemicals associated with sewage systems at various concentrations and can withstand hostile environments strongly due to their high resistance to abrasion, deterioration, breakage, and impacts.
