Pre-engineered airplane hangar or aviation hanger buildings are one kind of steel buildings that have been fabricated and manufactured at the factories and shipped at the construction sites, ready for assembly. After which they are built, the pre-engineered hanger buildings will join countless others of its kind all throughout the country that were built in major scale only in recent years. With the use of steel, manufacture and construction of pre-engineered steel buildings are much easier and not to mention, faster. Transportation of the materials is made much easier, considering that steel is a typically light-weight material. Surprising, considering that it is also one of the sturdiest materials around.   Beisdes meeting the building and steel construction codes, we will try our best to design and fabricate the pre-engineered airplane hangars less cost and saving energy. Our Bi-folded hanger doors are designed and fabricated with own patent technology.
