1. Tool selection: The fiberglass grille in the car wash room can be cut using a ceramic disc or diamond sand disc cutter to the desired size. When purchasing, we can cut it according to the size provided by the customer without charge.

2. Tool fixation: When using a heavy-duty cutting machine to cut, it is necessary to fix it properly to prevent the grille and cutting machine from moving.

3. Safety protection: Before cutting, operators should wear protective goggles, clear masks, gloves, and office clothes. They should choose a well ventilated and brightly lit place for cutting, as there is a lot of dust and it is necessary to pay attention to wearing masks.

4. Grille placement: After placing the bottom of the grille upwards and cutting it, it can reduce the germination of debris.

5. Size verification: Before cutting, please consider the width of the saw marks on the cutting edge. The length and width of the cut grille are biased towards -6mm~0mm; The circular diameter size deviates from -9.5mm to 0mm;

6. Post disposal: The surface of the cut grille needs to be coated with natural resin for processing, and the natural resin used should be higher than the grade of the natural resin used for the grille. For example, for adjacent benzene type grilles, meta benzene natural resin should be used to brush the surface to prevent corrosion of the glass fibers inside the substrate.
