Truck/Trailer Manufacturing

Rolling the parts that move America.

Our Role in Truck/Trailer Manufacturing

For over 25 years, Hynes has been recognized as the leading truck/trailer fabrication expert. Serving over 30 unique customers in this segment, our experience in this market is second to none. We collaborate with all segments of the truck/trailer industry to support custom builds for long haul trailers, final mile, platform and flatbed trailers, reefers, and RVs and buses.

We can build components to your specification with material thicknesses that range from .030 inches to .25 inches, and we work with numerous types of ASTM steel alloys including stainless, HSLA, hot roll, cold roll, galvanized and galvanneal, aluminum and more. Hynes often collaborates directly with OEM design engineers to reduce weight, trade-off material thickness vs. strength, and optimize cost, function and manufacturability.

Trust us to help you design and manufacture unique OEM shapes—to your specifications—for your trailer or truck body builds. Alternatively, look through our already tooled aftermarket parts catalog for profiles that we can produce with little or no incremental tooling cost.


We’re your go-to source for highly engineered, custom roll formed shapes for the truck/trailer industry. Our decades of design experience translate into an unmatched ability to offer the most functional and cost-effective roll formed solutions in the industry. Our engineering team brings creativity and a fresh perspective to product design.

Hynes has helped to co-design and develop numerous profiles for:

  • Structural rear frame, fan tail and bumper assemblies
  • Trailer side posts, roof bows, scuff/scuff plates, logistic posts
  • Cargo restraint systems including E-Track, A-Track and winch track
  • Welded assemblies and profiles

Let us collaborate with your team to design and manufacture weight-saving designs for your next OEM part.


Final Mile

Count on Hynes to be your trusted and reliable source for your final mile truck body builds. We realize that with the continued rapid adoption of e-commerce and at-home deliveries, reliable final mile truck body production has become critical to truck body manufacturers.

Hynes manufactures a variety of existing shapes including:

  • Longsills and crossmember profiles for structural framing
  • Roof bows, side posts, logistic posts and Z-posts

It’s possible we are tooled and ready for production on many of these parts.

Need a new design? Partner with us so we can bring your new design to life. We’re proud to support the final mile market as the world continues to shift to e-commerce and direct residential shipping.


Hynes is the industry leader in providing many of the common parts used in the aftermarket trailer refurbishment world. We support the largest aftermarket suppliers and distributors in North America, as well as OEMs that support their own aftermarket fulfillment programs.

From A-Track to winch track and everything in between, we have you covered. In a competitively priced market, we pride ourselves not only on our affordability, but—most importantly—on our service after the sale with proven, absolute reliability.
