Effective 02/12/2019: IPI is streamlining our sign posts offering! In order to continue to provide competitive pricing and lead times, IPI is reducing our square and u-channel post offering from nearly 40 sizes to only 15 standard sizes stocked in our warehouse. Existing stock is available at a 10% discount while supplies last; current inventory is noted on each discontinued size. Once inventory is depleted, non-standard sizes will be available for custom order only; longer lead times and minimum quantities may apply. 

  • Listed by height and width
  • Galvanized
  • Holes are 7/16" punched on 1" centers on all 4 sides down the entire length of the post
  • Additional post sizes are available upon request; allow a minimum of 8 weeks for delivery
  • Hardware for post assembly available to order; view the Square Post Assemblies & Fasteners guide for assistance
