Our aluminum trailers are built with high-quality materials, dependable components, and a constant focus on durability, function, and long-term value. Every PROLine trailer reflects our commitment to building products that are ready for real use and designed to hold up for years to come.
Since 2007, PROLine Products has earned its reputation through factory-direct sales, giving us a direct connection to the customers who use our trailers every day. That experience has helped us refine our designs, improve our ordering process, and better match each trailer to the customer’s specific needs.
With more than 24 years of manufacturing and sales experience, PROLine has developed a more refined, longer-lasting aluminum trailer built around real-world use. If you’re looking for an aluminum trailer made in New Hampshire and backed by a team that understands what customers need, PROLine is ready to help.
Great service means more than a smooth sale. It means clear communication, helpful product knowledge, and support that continues long after the trailer leaves our facility. Ask anyone who owns one of our trailers: we stand behind what we build.
For the better part of 17 years, PROLine sold trailers strictly factory-direct to the end user. That direct connection helped us fine-tune our craft, improve our designs, and better understand how trailers are used in the real world. Today, that customer feedback still shapes the way we build.
Our aluminum trailers are built to last, starting with rugged main tubes and fully welded joints. We know what types of roads our trailers are dragged over when they leave our facility and our trailers are ready for them.
A strong frame is only as good as the components to support it. This is why we use only the best of parts on our aluminum trailers like galvanized torsion axles, high quality radial tires, all LED lighting, and self-adjusting brakes.
Our roofs are built with rugged 1″×2″ aluminum tubes on 16″ centers. That means a roof nearly 2.5 times stronger than many other trailers on the market. We tend to get a lot of snow in New Hampshire, our trailers are ready for it.
Every trailer we build is checked and double checked before it leaves our shop. We want to make sure our trailers are looking their best with screws lining up, lines cut straight, doors installed tight, and every trim screw properly located.
