Stiffeners increase the weight of a steel door, putting significant pressure on the opening and sometimes making them difficult to open for seniors and children. The vertical stiffeners in a hollow metal door also mean that pressure on the corners or the sides of the door with cause it to twist. Last but not least, stiffeners are welded into a steel door every six inches which may result in blemishes on the surface. Our fully welded seamless door does away with all of those disadvantages while saving you money.
