Fully-Welded Frame

Attention To Detail

Customer Service

We fully weld all of our trailers to help build the strongest aluminum trailer we can. We know what types of roads our trailers are dragged over when they leave our facility and we expect our trailers to tow straighter and last longer.

Factory Direct Pricing

You’ll find we’re priced right in line and often times quite less than other aluminum trailers. But you won’t find the quality or attention to detail in those trailers as you will with a trailer from PROLine Products.

Family Owned

PROLine Products is family owned and operated. Any time a customer calls a family member answers the phone to make sure questions are addressed in a timely manner. This is a key ingredient to our top-notch customer service.

Founded on Quality First

Durable Aluminum Frames

At PROLine we have thousands of dollars invested in custom aluminum extrusions to make you the strongest trailer possible because we know what happens to trailers when they leave our facility. They’re immediately dragged over some of the worst roads in the world.

This is why we’ve designed all our trailers to handle those… 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. Something you’d never see unless you rip out the floor but it makes for a much stronger trailer.

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

PROLine's Roof Structure

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 you buy trailers to use as a garage!

So why would 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 1×2 aluminum tubes and put them 16″ on center. That means a roof nearly 2.5 times stronger than many other trailers on the market.

We Never Enclose An Open Trailer

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 component frame (Uni-frame).

This combined with the fact that every enclosed trailer is built on a 2×5 (or larger) aluminum main frame means you’re getting a stronger trailer across the board.

Tie-Down Security Systems

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 component frame (Uni-frame).

This combined with the fact that every enclosed trailer is built on a 2×5 (or larger) aluminum main frame means you’re getting a stronger trailer across the board.

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 tiedown installed on your trailer it was done properly.

All of our D-rings have a proprietary aluminum backing plate that is 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.

Proline's quick adjust rail systemOur Quick-Adjust Floor Rails are welded to both sides of 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 two aluminum tubes between every single wall upright to ensure that every screw that holds up your E-track is going into something more than just plywood.

Attention To Detail

Every trailer is checked and double checked so it leaves our shop looking its best. We make sure that every trailer that we put out 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 enters our showroom 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 customers and our products. 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.

High Quality Aluminum Trailer Components

What good is a strong frame if you don’t have the components to support it? This is why we use the best parts we can find to go into our trailers.

Axles

We only use Dexter Torflex Axles™ on our trailers and these axles all carry a 5 year warranty on their suspension systems. Torsion axles provide a smoother, quieter ride and last much longer than spring axles. These axles also come equipped with E-Z Lube Hubs. When installed our axles aren’t bolted through the frame that would result in a stress point in the frame; we weld on axle plates and bolt through the sides.

Wheels

We don’t carry a painted steel rim. Why buy a nice aluminum trailer just to have the wheels rusting almost immediately? Our standard wheel is galvanized to make sure it stays looking great for a long time. And of course we offer an upgraded aluminum wheel option.

Lights

LED Lights are standard on every one of our trailers. Also we never use a single diode LED as a clearance light! Our clearance lights all have multiple diodes in them for a better quality and brighter light. Additionally, EVERY PROLine enclosed trailer comes standard with multiple interior lights that are switched by the side door and in most cases there are 3 or 4 lights. We like to see what we’re doing, we figured you probably do too.

Hinges

Our ramp door hinges are aluminum and equipped with grease fittings to keep them operating smoother longer. No more stainless steel strap hinges that get brittle over time and break.

Tires

We use quality tires on ALL of our trailers. All of our radials even come with a 5 year warranty and roadside assistance!

Brakes

If one of our trailers has brakes on it we don’t skimp and use the cheap 8″ brakes. We use the full size 10″ electric brakes and the brakes go on both axles on the tandem axle trailers. No nonsense charges and hidden fees either. And now we’re even using Self Adjusting Brakes for all of our brakes! Saving you time and money but more importantly, making sure your trailer will stop when you need it to! Additionally we mount the battery breakaway system INSIDE the trailer, not on the tongue like other manufacturers. For the 30 cents in wire it costs us to mount it inside we’d much rather have it work if you were to ever need it than rot away in the snow and the rain.

Electrical

We’ve heard it too many times that trailer lights only work for the first year and then the corrosion kicks in. Before you know it you’re re-wiring that “brand new” trailer. This is why we run all of our electrical for the lights inside the trailer and not along the frame. The only wires run along the frame are for the trailer brakes which are coated in a waterproof insulation.

Other Components

Stainless steel carriage bolts fasten our hinges and door barlocks to the trailer frame for security and long term good looks. We use hardened bolts to mount our axles to the frame and for our trailer couplers. We fasten our electric brake wire to the frame with vinyl coated metal clamps screwed to the trailer frame, not the stick-on variety others might use.

Common Questions We’re Asked

Why are your aluminum trailers more or less expensive?

Yes, we hear this question on both ends of the spectrum. If you find our trailers expensive, odds are you’re either comparing it to a steel framed trailer (which would be MUCH less expensive than ours) or another aluminum trailer without the same great features that we put standard on all of our trailers.

Price out that same enclosed aluminum trailer with the features we give you standard on most of ours (Dexter Torflex Axles w/ EZ Lube Hubs, galvanized wheels, radial tires, LED lights, 3/4″ flooring, quality side doors, ramp doors with spring assists, roof and walls on 16″ center, all aluminum & fully welded tubular frames, etc).
You’ll find we’re typically priced right in line and often times quite less, and you want find the quality in whatever other brand trailer as you will in a PROLine Products LLC trailer.

Why don't you have any dealers?

In our time of making trailers, we’ve found that “trailer dealers” typically only try to sell what they have sitting on their lot. Here at PROLine, we pride ourselves on selling the right trailer to the right customer so it’s best our customers contact us directly to help them get into the perfect trailer for their needs. Being the manufacturer we’re just as happy to custom build a trailer for someone as to sell them one off our lot. It’s all about identifying and meeting our customer’s needs then exceeding their expectations.

Do you perform trailer repairs?

If a trailer that was originally made by PROLine Products LLC is damaged we are happy to help and get it back on the road, however, we DO NOT do any repairs on any other brand’s trailers.

How long does it take to build a trailer?

Lead times typically keep us out anywhere between 3 and 6 weeks but can be longer. If you need a trailer in a hurry please check out our inventory page to see what’s currently available. Also, don’t be afraid to call because we’re always building trailers to have in inventory and may be building exactly what you need.

What methods of payment do you accept?

For deposits we can take Visa, Mastercard, Discover, cash, or check. For final payment of your trailer we request that you pay in cash or a bank check. We also have financing available through Sheffield Financial.

Can I come look at your trailer inventory?

The overwhelming majority of our completed trailers are stored in a warehouse until they’re purchased and picked up. If you come during business hours we can show you our current inventory as well as any completed and ready to pick up trailers. So come on by and check out why PROLine aluminum trailers are the best quality and best value.
