Product Description
The FRP Grating Mold is built for FRP grating production. It has a precise shape and standard sizes. The mold uses high-strength FRP material , so it fights corrosion and aging. It is very rigid, so the mold doesn't bend or wear out fast. The gaps are even , so cast gratings come out with neat grids and consistent hole sizes. Demolding is easy , so there's no sticking or edge damage. You can use the mold 80+ times. It works with different grid sizes and thicknesses. We can also offer flat or anti-slip grating surfaces. This mold replaces old metal molds, so it cuts maintenance costs.

Product Advantages
You pay less for each grating mold when you use it over 80 times.
You do not need to trim parts by hand because the grid spacing is even from casting.
You get no rust problems from metal molds when you work with acid resins.
Main Applications
This FRP Grating Mold is used by FRP grating makers. It makes gratings for chemical plants, city works, power stations, and water treatment. It works for both molded and pultruded grating making. The types include platform gratings, walkway gratings, trench cover gratings, and stair tread gratings. This mold is also called a Fiberglass grating mould or fiberglass grating mold.
Frequently Asked Questions (FAQ)
Q: How many times can I use the mold before it needs to be replaced?
A: If you clean and store it well, you can use it 80 to 120 times. After that, the grid edges may show some wear. But many users keep using it past 120 times. They just need a little more time for demolding.
Q: Can I use the same mold to make different grating thicknesses?
A: No. The thickness is set by the mold shape. So you need a different mold for different thicknesses. Tell us your target thickness when you order.
