Welding Versus Bolting Top Track

Most hangar door manufacturers supply top tracks for their hangar doors with a bolted connection. They do it this way because it is easier and cheaper for field technicians to install their product.

However, Aero Door case studies over the years have shown that not welding the top tracks creates significant issues with how the door operates.

Every steel building has some sort of movement over time. Steel building structures shift and sag over time this is inevitable. These variations cause the top track to become misaligned over time. When the top track becomes misaligned this may cause your door to stop working because it gets stuck on the misaligned top track.

This results in an expensive service call to repair your door. Additionally, when companies provide a bolted top track connection the bolts may become loose over time from vibration.

Loose top track could cause catastrophic failure of your hangar door putting your plane or personnel at risk. Welding eliminates these hazards completely. Buying a hangar door from Aero Door will result in a lower cost of ownership during the lifespan of their door.
