Cut fiberglass grating only after completing its entire production. Manual cutting requires the cutting staff to control the machine. Large cutting machines have small errors and need fixing before cutting. When cutting, the installation size should be 2mm-5mm smaller than the customer's requirements. This allows space for the grille panel.

1) Tool selection
Linear cutting: You can cut fiberglass grating on-site with mechanical methods. Use ceramic or diamond disc cutters. Ordinary steel saw blades can cut it, but they are not recommended.
Curve cutting: Use electric or steel saws with metal cutting blades to cut grids, arcs, and curves. The picture shows a portable cutting machine:
Handheld cutting machine
Polishing: Use handheld angle grinders, grinding machines, files, or sandpaper.
Drilling: Drill holes over 12mm with Fried Dough Twists drills. Use portable electric hole machines or ordinary electric hand drills for small holes.
2) Conventional cutting method
Type A: Surrounding edges (optional tooth edges)
Surrounding edges
Beautiful and neat, but relatively high cost. The grille is wrapped with edges. Its length and width must be: N (number of grids) * single grid size (38.1) + grid width (7) mm. It is commonly used for whole page installation in car wash rooms.
Type B: Edge wrapping
Edge wrapping
Neat, relatively high cost. One set of edges must meet A-type size. The other set must be symmetrically cut.
Type C: Adjacent bread edges
Adjacent double-sided edging
D-type: Three sided bread edge
Three bread edges
After paving, it is neat and relatively beautiful, commonly used in trenches and corridors.
E-type: sequential cutting method
Sequential cutting method
The most economical methods, like full, no, and partial edge wrapping, may coexist after paving. They may be messy, so it's best to avoid them.
3) Cutting error
The cut grid's accuracy is ± 5mm. This is due to factors like the blade width and its angle to the grid.
4) Detail processing after cutting
After cutting is completed, resin needs to be used for coating processing. The resin used should have more stable properties than grid resin. For example, ortho benzene type grids use meta benzene resin to cover the cutting surface. It protects the exposed glass fibers from erosion after cutting.
be careful:
a. This material cannot be turned or tapped.
b. Arbitrary cutting will not affect the grille's properties. It won't cause scattering or other issues.
c. The fiberglass grating cover on the entire side looks neater. It is stronger under stress and less likely to cause injury during installation.
d. When cut into rough edges, there will be edges and burrs, which are slightly less stressed. When the load-bearing capacity is too high, the edges are easily damaged, but it can save materials. So, it is best to cut the fiberglass grille cover and tree grate of the car wash room as much as possible into a whole edge. This will ensure load-bearing capacity and aesthetics.
e. Fiberglass grating cover plates are usually 1.22 * 3.66. This is for easy handling, transport, and installation. They are usually cut along the 3.66 direction, with a width of 1.22 as the length. This makes them small and easy to package, transport, and install.
