The Performax® steel component shelving system is designed to offer maximum flexibility as well as ease and quickness of assembly. This modular shelving system includes beams, end frames, tie bars, and shelves. Each welded end frame features tapered slots for the bracket tabs on the steel racking beams to fit into. The precut shelving rests on the stepped surface on top of the racking beams for easy assembly. Customize your system by adding accessory hooks (sold separately).
