Post Frame

Post Frame

Here at Graber Building Supply, we stock a full line of accessories for Post Frame Buildings including: posts, insulation, doors, and windows. We are a dealer of quality metal roofing and siding panels from Graber Post Buildings Inc. from Montgomery, IN and are on a daily truck schedule with them, giving us an incredibly fast turn around on building packages. We offer packages for do-it-yourselfers and contractors and have the capability to produce drawings and 3D images if needed.

Looking for a contractor to build your new building? We have our own crews based out of our location here at Sullivan, who have many years of experience with Post Frame construction. We also work with many Contractors throughout central Illinois, so feel free to ask us for a recommendation for a builder in your area!
