Pro-Tec Options

Single Tube and Truss Arch Options
As part of our ventilation system, the Single Tube building increases air flow and reduces humidity. Buildings can be designed and customized to your specific needs. Backed by a 15 year pro-rated warranty on the cover, full 3-year warranty on the frame and 1-year warranty on the track door.

Color Options:
For double strength, all covers are sewn or welded into one continuous layer to stand tough against the elements.

Protection from the elements.  Our durable awnings shelter feeders and bar direct sunlight from your livestock.

Side Curtains:
Curtains can be drawn down to help circulate air flow or kept up to block direct sunlight.


Ridge Vents:
Ridge vents allow for more air flow and a much wider air pattern.  This maximizes heat distribution and humidity control.

Track Doors:
Looking for a clean outwardly appearance for your ProTec building?  Our track doors are a perfect solution to aesthetics and function, offering a great external appearance and large entrance clearance.


Roll-Up Doors:
Our roll up doors shield your ProTec buildings interior space against energy loss and are available in a variety of colors.
