The mainstream FRP gratings on the market are mainly divided into molded gratings and pultruded gratings.
FRP molded grating is made of continuous glass fiber criss-cross weaving, resin pouring and integral molding, with many regularly distributed rectangular and square blank FRP grating plates.
The standard surface of the molded grille is a grooved surface, which has a good anti-slip effect. Users can also choose to grind the surface or sand the surface to prevent slipping according to actual needs. It can also be covered with a sealing plate on the surface to prevent small objects from falling, or it can be used in areas with high heels.
The thickness of the molded grid bars, the height of the plates and the size of the grid spacing are all fixed.
Fiberglass grating
Molded gratings are often used in high-altitude exposed areas, hot and humid areas that are prone to rust, acid-base and salt corrosion areas, and are used as trench covers, operating platforms, and walkway panels.
FRP pultruded grating is a kind of load-bearing plate assembled by using pultruded profiles (usually I-beam or T-shaped steel or flat bars) as load-bearing gratings, and rods and pipes as connecting rods.
Pultruded grids can change the spacing of the grids to produce variable porosity. Customers can choose the position of the connecting rods, the size, shape, color and surface form of the stressed grids (the area with oil stains, the surface can be selected) Add sand to prevent slipping).
The application environment of pultruded grid is basically the same as that of molded grid (usually users choose to use it for water or high-altitude plank road). T-shaped or I-shaped gratings with a wide surface are especially suitable for areas with bare feet walking on the water's edge and large-span areas. Fiberglass pultruded grating is the perfect complement to molded grating applications.
The biggest difference between pultruded grating and molded grating is that pultruded grating is unidirectional.
