Product Description
The FRP Drainage Ditch Cover Mold uses high-quality FRP composite. So it is light, strong, and hard. It does not bend or wear out fast. It fights corrosion and aging. The mold handles wet outdoors, acid/alkali soil, sewage, and weather. The mold shape is exact with neat edges. Joints fit tight, so no slurry leaks out. Demolding is easy and smooth. No sticking or edge damage happens. Cast covers come out with correct size, smooth surface, and even load distribution. You can reuse the mold 70+ times. It works for different sizes and hole patterns. You can get anti-slip, open, or solid covers. This mold replaces old metal and concrete molds. So it cuts production and maintenance costs.

Main Applications
This FRP Drainage Ditch Cover Mold is used by cover makers, municipal companies, industrial builders, and farm water projects. It serves road drains, garden drains, factory sewage/storm drains, farm irrigation drains, and school/park drains. It makes anti-slip covers, open drain covers, and solid protection covers. The covers work with FRP drainage ditches for protection, slip resistance, and debris blocking. This mold is also called a fiberglass drainage ditch cover mould or fiberglass trench cover mould.
Frequently Asked Questions (FAQ)
Q: How many cycles before the mold needs replacement?
A: With good cleaning and storage, you get 70–120 cycles. After that, edges may show minor wear. Many users keep going past 120 with slightly longer demolding time.
Q: Can the same mold make both open (hole) and solid covers?
A: No. Open and solid covers need different mold surfaces. Tell us your hole pattern when you order.
