Why Welded Corners?

A welded corner is the strongest type of construction available for a storm door. We guarantee it. Consider the strength of a continuous weld holding your door together compared to a corner held together with sheet metal screws. This photo shows what can happen to a screwed-together corner on a non-welded storm door. The screws in the edge of the door have given way and the door has split at the corner. This will never happen with a Trapp^® Storm Door with heliarc welded corners. The weld is guaranteed never to break. If it does, we replace the door. It’s that simple.
