Aluminum Construction Trailers

7-1/2' Wide Enclosed Aluminum Construction Trailers

Our latest addition to our all aluminum construction trailers and contractor trailers is our 7-1/2' wide version. Perfect for those of you who don't want an 8' wide trailer but find the 7' wide version a little too tight. All of our construction trailers are built on fully welded heavy duty all aluminum frames to make sure they're ready for your day-to-day operations so you and your crew can get to work.

With dozens of options available give us a call so we can customize one to perfectly fit your needs. All of our trailers have screwless sides to make sure your lettering or graphics look their best and consider adding roof racks and the front ladder for the ultimate in versatility. We even have an abudance of 110 Volt Packages to make your trailer your own mobile workshop! All this with the same great standard features you'd expect from PROLine: side access door, choice of rear ramp door or cargo doors, aluminum stoneguard on the front, LED lights, multiple interior lights, tongue jack, and rugged 3/8" plywood finished interior walls are just some of the standard features on our all aluminum construction trailers.

Make your next trailer your last! No rust, long lasting aluminum.
