This composite mesh with a 4.0 mm bar and 20 x 20 cm openings is a serious replacement for heavy steel rebar where metal cannot withstand corrosion. Four millimeters of fiberglass, twisted into a ribbed profile, provide high tensile strength at a fraction of the weight. Instead of steel, it uses fiberglass in epoxy resin — it does not rust, resists salt water, acids, alkalis, and chemicals. The 2 x 25 meter sheet provides 50 square meters of continuous reinforcement with minimal overlaps. The twisted surface ensures bonding with concrete no worse than that of steel rebar.
The mesh is designed for the harshest operating conditions where steel fails within a couple of seasons. It is ideal for marine and coastal structures: breakwaters, piers, docks, seawalls, erosion control structures. It is used in swimming pools, water parks, wastewater treatment plants, drinking and industrial water tanks, and chemical reagent containers. In industrial construction, the mesh is used for foundations in chemical, petrochemical, and food industry facilities, for floors in workshops with aggressive environments, and for road slabs in areas with high groundwater levels and saline soils.
The main advantages are absolute corrosion resistance and near-weightlessness compared to steel. Fiberglass leaves no rust stains, does not deteriorate from within, does not conduct electricity, and creates no radio interference. The mesh is so lightweight that one person can lay it without cranes or helpers. The 4.0 mm diameter provides a safety margin sufficient for serious loads. If the project is near water, in a swampy area, or in a chemically aggressive environment — this mesh will outlast steel by many times and will not require costly repairs in a couple of years. 50 square meters per roll is convenient for transport and cutting.
