Founded on a legacy that began in 1973 with Glen S. Graber’s three-man Amish building crew, Graber Post Buildings has evolved from a small post-frame operation into an industry leader, highlighted by Glen’s 1993 Entrepreneur of the Year Award and a massive 300,000-square-foot expansion in 2007. Today, Indian Bluff Supply continues this tradition of excellence by providing contractors with high-quality, affordable materials for pole buildings and barns. Committed to supporting time-sensitive projects, we offer specialized services—including a 3D Design Your Own tool for instant material lists—to ensure our customers have the reliable supplies and modern resources they need to succeed.
Quality Materials from a Trusted Partner: Metal Sales
To ensure the highest standard of durability for every project, Indian Bluff Supply partners with Metal Sales Manufacturing Corporation, the nation’s premier manufacturer of metal roofing and wall systems. Founded in 1963, Metal Sales has spent over 60 years perfecting the production of high-quality steel and aluminum materials that are engineered to last upwards of 50 years. By sourcing our steel and custom trim from a partner with 21 facilities across the U.S., we provide contractors with energy-efficient, ENERGY STAR®-listed products that offer superior resistance to fire, wind, and corrosion. This partnership allows us to combine local, reliable service with industrial-grade materials, ensuring your pole buildings and custom homes are built with the strongest steel in the industry.
