Composite Catwalks for Tanker Trucks: What to Know

Tanker trucks operate in some of the most demanding conditions on the road. Whether hauling fuel, chemicals, food-grade liquids or other bulk materials, these trucks may encounter frequent washdowns, moisture, road spray, winter road salt and long hours in changing weather conditions.

For tanker fleets and owner-operators, equipment needs to stand up to that environment day after day. That includes something as seemingly simple as the catwalk or deck plate behind the cab.

For decades, steel and aluminum have been standard materials for semi truck catwalks. But tanker operators looking to replace or upgrade a traditional metal deck plate now have another option: high-strength composite.

The Wave Deck from HQ Truck Parts offers a composite alternative designed for compatible Class 8 trucks — including trucks pulling tanker trailers.

Why Consider Composite for a Tanker Truck Catwalk?

Tanker operations can put equipment through conditions that make material choice especially important.

A catwalk behind the cab is exposed to the elements while sitting in an area that drivers regularly access and where important air and electrical connections are located. Depending on the operation and route, that can mean repeated exposure to water, road grime, salt, snow and temperature changes, along with routine cleaning and washdowns.

Traditional metal catwalks have been used throughout the trucking industry for decades. They work — but metal also comes with characteristics worth considering in these demanding environments.

The Wave Deck approaches the same job with a different material.

Composite Won't Rust

For tanker trucks operating year-round, exposure isn't occasional. Rain, snow, road spray, moisture and winter road salt can all become part of the truck's regular operating environment. Tanker equipment may also undergo frequent cleaning or washdowns depending on the type of operation.

Steel exposed to moisture and road salt can eventually rust and corrode. The Wave Deck is made from high-strength composite, so it won't rust like steel. That means tanker operators don't have to deal with rust-related maintenance on the deck itself.

Built for an Area That Gets Wet, Dirty and Used

The space behind a tanker truck cab isn't a protected environment.

Road spray can come up from below. Dirt and grime accumulate during long routes. Trucks operating in northern climates encounter snow, ice and deicing salts. Depending on the operation, regular washing can introduce even more moisture.

That's why the material used for a truck catwalk matters.

The Wave Deck's composite construction provides a solid working surface without relying on steel that can rust after repeated exposure to moisture.

No Sharp Metal Edges Around Critical Connections

The area between the truck and tanker trailer contains connections that are critical to reliable operation.

Air and electrical lines run through this space, often underneath or near the truck catwalk.

Traditional metal deck plates can introduce metal edges and contact points in the same area. Over time, contact and movement can create potential wear points around nearby lines.

The Wave Deck's composite construction means there are no sharp metal edges around the deck plate, providing a different approach in an area where protecting critical connections matters.

Designed to Help Protect Critical Lines

When a truck is working every day, an issue with an air or electrical line can mean more than an inconvenient repair — it can mean downtime.

The Wave Deck is designed to provide a solid working surface while helping protect the critical lines located around the catwalk area.

For tanker fleets operating multiple trucks, reducing potential wear points in this area is another factor worth considering when evaluating catwalk materials.

Lightweight Composite Construction

Tanker operators already have plenty to consider when it comes to truck and trailer weight.

The Wave Deck uses lightweight composite construction, providing a strong working surface without relying on traditional heavy metal construction.

For a single truck, the difference may seem small. Across a larger tanker fleet, however, equipment weight is one more consideration when evaluating components and replacement parts.

Made in the USA

The Wave Deck is manufactured in Michigan, providing tanker fleets and owner-operators with an American-made alternative to traditional metal truck catwalks.

What Size Wave Deck Does a Tanker Truck Need?

Every truck setup is different, which is why The Wave Deck isn't limited to a one-size-fits-all approach.

The Wave Deck is available in standard 10-inch and 20-inch sizes, and multiple Wave Deck sections can be connected together to create larger configurations based on the available space behind the cab.

Need something different? Custom sizes are also available.

This flexibility can be especially useful for tanker trucks and specialized fleet applications, where equipment placement and available space behind the cab may vary from truck to truck.

Need a Custom Catwalk Size?

Whether you're outfitting a single tanker truck or evaluating The Wave Deck across an entire fleet, contact HQ Truck Parts to discuss custom sizing and configuration options.

What About Chemical Exposure?

Tanker operations can involve a wide variety of substances depending on what's being hauled, how the truck is used and how the equipment is cleaned. While composite materials can offer resistance to certain types of corrosion, chemical resistance depends on the specific material and substance involved.

If your truck's catwalk is regularly exposed to specific chemicals or other substances, contact us to discuss your application and determine whether The Wave Deck is appropriate for your operating environment.

Is The Wave Deck Only for Owner-Operators?

No. The Wave Deck can be considered by both individual owner-operators and commercial fleets, including fleets operating tanker trucks.

For tanker fleets, equipment decisions that seem small on a single truck can become much more significant when multiplied across dozens or hundreds of vehicles.

Factors such as corrosion, maintenance, weight, durability and protection around critical lines can all become part of the bigger fleet maintenance picture.
