How H-20 Trench Covers Support Vehicle and Truck Traffic

Gearing up to tackle an infrastructure project? Whether it’s for an amusement park, themed resort, casino, or even a transit hub, one of the unsung heroes of the project is the trench cover system. As they help vehicles and trucks safely travel over cables, piping, conduits, and other working lines, you need a cost-effective option built for strength and reliability. That’s where fiberglass H-20 trench systems come into play.

What Does “H-20” Mean?

H-20 is a load rating defined by the American Association of State Highway and Transportation Officials (AASHTO). It signifies that the trench cover can withstand heavy wheel loads, making it suitable for use where buses, trucks, and large work vehicles frequently cross.

For projects where utility, cables, or piping must pass beneath roadways or service areas, an H-20 road crossing trench ensures the infrastructure below is protected while the surface above stays safe for vehicle use.

Why H-20 Trench Covers Work So Well for Heavy Traffic

Engineered Strength

H-20 trench covers are designed and tested to handle repeated heavy loads without shifting, cracking, or failing. This makes them ideal for industries that experience high volumes of traffic.

Long-Term Durability

Unlike an H-20 concrete trench that’s prone to cracking over time, our fiberglass H-20 trench systems offer dependable performance for years, not only reducing costly downtime but also avoiding unexpected repairs. Our covers also resist wear from chemicals, weather, and continuous use.

Seamless Integration

Trench systems can be designed to sit flush with surrounding surfaces, creating smooth transitions for truck traffic. Because integration can be so seamless, you can reduce vibration and wear on passing vehicles.

Flexible Design

Every project has unique requirements. From trench width and cover thickness to fastening details, we can engineer H-20 trench covers to your exact specifications. That flexibility makes them a fit for a wide range of applications and environments.

H-20 Trench Covers in Action

RV & Mass Transit Facilities

Bus yards, staging areas, and RV parks frequently rely on H-20 trench systems to protect underground utilities while supporting a constant flow of vehicle traffic.

Theme & Amusement Parks

Attractions often need trenches for utilities that cross under guest pathways or service roads. With H-20 trench covers, maintenance trucks and supply vehicles can safely cross without disrupting the guest experience.

Casinos & Restaurants

Delivery trucks and service vehicles can strain your lanes and parking decks. An H-20 road crossing trench ensures the surface is strong enough to handle the load while protecting critical utilities.

Storefronts & Commercial Spaces

From HVAC lines to electrical cables, utility trenches often need to cross high-traffic areas. With H-20-rated trench covers, businesses get an affordable system built for both performance and reliability.
