        FRP grille has an irreplaceable superior function in the field of anti-corrosion. In the process of selection, the material of m-benzene, o-benzene, ethylene and other substrates can be reasonably selected and applied according to their practical application. Holes over 12 mm can be drilled with twist drills on general drilling machines.

Holes over 12 mm can be drilled with twist drills on general drilling machines. The FRP grille equipment in car wash room can be polished by hand-held angular polisher, grinding wheel, general file and sandpaper. Curve cutting: grille opening, arc cutting and other arc cutting can adopt electric saw or steel saw with equipment metal cutting blade.
        Excellent! FRP grids can also be used in corrosive environments
        FRP grille is actually a kind of sheet material with many blanks formed by resin through its special processing and compounding. It can be used as its structural data when it is used. FRP grille can also be used in corrosive environment. The product has excellent corrosion function of alkali resistance, acid resistance, organic solvents, salts and many other gases.
        FRP grids can also be used in civil construction facilities. The service life of FRP grids is very long in the process of application. The cost of operation is relatively low. It is very safe and reliable in the process of operation and does not need maintenance. The equipment of FRP grille has many kinds of equipment methods according to engineering design and use. Now there are mainly four kinds of equipment methods: staircase equipment, ditch equipment, floor equipment and support beam equipment.
        The raw material of FRP grille is very light and its density is relatively small. The equipment in the area with high groundwater level presents the condition of floating pipe briefly. If necessary, anti-floating measures such as runoff guidance of rainwater can be considered. The surface of FRP grille is very beautiful. It has become standardized, commercialized and serialized when it is used in production. Such products are not considered to be the most economical and reasonable information, so they are used in many ways.
        This information cannot be turned or tapped. Before incision, operators should wear protective glasses and masks to avoid splashing objects into the eyes and reduce dust inhalation; wear gloves and work clothes to avoid dust entering the skin and allergies; select ventilated and bright places for incision; before incision, all electric tools should be checked for safety.
        Small holes can be drilled by hand-held electric hole processing tools or general hand electric drills. According to the scale and equipment requirements, the grille is cut and processed reasonably in order to maximize economic benefits without affecting the connotation and function of the grille. The cutting end surface needs to be coated with resin to ensure that its anti-corrosion function is not affected. Straight cut: FRP grille can be cut on site with ceramic disc or diamond cutter, or even with general steel saw blade.
