Top-Rated Enclosed Aluminum Trailers

We’ve invested thousands of dollars in custom aluminum extrusions to help make you the strongest trailer possible. We know what happens to trailers when they leave our facility, they’re immediately dragged over some of the worst roads in the world and they need to work time, and time again. You don’t want to spend your vacation time fixing your trailer and we don’t want you to either. Our frames are designed to be trouble free for years to come.

This is why we’ve not only designed our aluminum trailer frames to handle this abuse but we go even further; we fully weld all of our trailer frames. This means we actually flip over the entire trailer deck and weld the other side. Resulting in twice as many welds than most other companies to produce a much stronger frame. This is something you’d never see unless you rip out the floor but it makes for a much more durable trailer.

This is one of the many reasons why PROLine aluminum trailers tow straighter and look better, longer.

Let’s be honest, not everyone has a garage big enough to house an enclosed trailer, not everyone even has a garage. Even further, a lot of people buy trailers to use as a garage for your snowmobiles, motorcycles, and ATVs!

So why do other companies build a trailer that can’t handle a snow load? We live in and use our trailers in a snowy climate so I can’t answer that for you but snow doesn’t bother us or our trailers.

We build our roofs with rugged 1″ x 2″ aluminum tubes and put them 16″ on center. That means a roof nearly 2.5 times stronger than many other trailers on the market. This doesn’t mean that you can leave your trailer in Northern Maine and let 10′ of snow pile up, but when you see a Nor’easter in the forecast you’ll feel confident your trailer will be recognizable the next time you see it!

PROLine’s trailer structures are fully integrated components, each and every sidewall upright is welded directly to the trailer deck and to the roof creating a single structure. Prior to welding, every trailer gets checked to make sure it’s square, clamped in with additional bracing to lock in those dimensions, and then welded. This minimizes weld distortion to make sure your trailer will be put together square, keeping your trailer nice and tight and the weather out.

Odds are you’re likely buying a trailer to haul around some prized possessions. Whether it’s your new (or old) Mustang, a few snowmobiles, or your precious motorcycle.

When you tie these items down to the trailer you need confidence that they’re going to stay there for the duration of your trip. We can’t tie down all your cargo for you but you can be sure that whenever there is a tie down installed on your trailer it was done properly.

All of our D-rings have a proprietary aluminum backing plate that gets welded to the trailer frame so when you’re tying down that new Porsche you don’t have to worry about pulling up the trailer floor. Same thing when tying down to our Quick-Adjust Floor Rails.

Our Quick-Adjust Floor Rails are welded to every floor cross member, effectively tying down to the frame, not the floor.

And the optional E-track on the walls of our trailers? We weld in additional aluminum tubing to the wall uprights to ensure that your E-track is properly locked into the trailer walls.

Every trailer is checked and double checked so it leaves our shop looking its best. We make sure that every trailer we produce leaves looking clean, with screws lining up, lines cut straight, doors installed tight, and every trim screw properly located.

Some might wonder if it’s worth giving a trailer this much extra attention, but every time a customer sees one of our trailers the look on their face assures us we’re doing it right.

It’s the little things we do that let you know we care about our products and our customers. Whether it’s the rain gutter over the side door or all the interior lights that come standard; we want to build you the absolute best trailer possible.
