Post Frame Buildings
Gateway Building Systems offers post-frame construction, also known as pole barns, structures characterized by a simple and efficient construction method. They utilize large wooden posts or columns that are strategically placed to support the building’s roof and walls. The design allows for wide, open spaces without the need for interior load-bearing walls.
