SMC manhole covers are made from fiberglass reinforcement and
unsaturated resin, molded under high temperature and pressure to
ensure excellent mechanical strength and durability. The covers
resist compression, impact, and abrasion, and they are not prone to
cracking or deformation. Unlike cast iron or concrete covers,
composite materials are eco-friendly, rust-free, and theft-proof.
Their lightweight design allows for single-person installation,
greatly improving construction efficiency. With flexible surface
patterns and multiple load classes, these covers meet the
requirements of sidewalks, residential streets, or heavy-duty road
applications. Anti-slip treatment further enhances pedestrian and
vehicle safety, making SMC covers an ideal solution for modern
infrastructure projects.
SMC composite manhole covers are engineered to deliver a balance of
strength, safety, and long-term performance. Manufactured using
sheet molding compound, which is a blend of unsaturated resin,
fiberglass, and filler materials, these covers are
compression-molded under controlled conditions to ensure consistent
density and high mechanical strength.
The performance benefits are notable. They offer excellent
load-bearing capacity and can be tailored to meet different classes
of EN124 requirements. From residential walkways to heavy-traffic
roadways, SMC covers provide a reliable solution. They are
resistant to cracking under heavy loads, and their elasticity gives
them an advantage in withstanding sudden impacts.
Durability is another defining feature. Unlike cast iron, which
rusts and weakens over time, or concrete, which can crumble under
stress, SMC composite covers resist corrosion from water, salts,
chemicals, and even petroleum products. This makes them especially
suitable for coastal cities, industrial facilities, and areas with
aggressive soil conditions.
Practicality is also key. Their lightweight construction reduces
logistical costs and allows installation to be performed by one or
two workers without heavy equipment. Municipal agencies benefit
from reduced labor costs and faster project completion times.
Anti-slip textures are molded onto the surface to reduce accidents.
Covers can also be produced in different shapes—round, square, or
rectangular—to fit varied infrastructure requirements.
Applications are broad. SMC manhole covers are widely used in
telecommunications, water supply, gas pipelines, power
distribution, and stormwater drainage. They are increasingly
adopted in airports, ports, industrial parks, and smart city
projects, where safety, longevity, and reliability are top
priorities.
