Every post frame farm building will be constructed with high grade lumber with poles treated to withstand the test of time. Need large door openings and open space to move around - not a problem.

Most buildings have no interior poles with the ability to span up to 100 feet wide and sliding doors 36 feet wide or more. Move equipment in your pole barn with ease. Our farm buildings use double trusses for added strength and added flexibility.

A new agricultural building can be constructed with fewer resources than tradtional construction methods which lowers cost per sqaure foot of usable space.
