SHaDE Commercial Grade Market Umbrellas are made with all aluminum oval shaped tubing and have a sturdy non-tilting frame. The break-down pole makes the umbrella easy to transport and instead of loose fitting snaps it screws together or a tight sturdy fit that doesn’t wobble or flex. As always, the canopy is connected to the frame with quadruple reinforced fabric tabs and stainless steel hardware. These steel nuts and bolts so that virtually any part can be repaired as needed. All SHaDe Commercial Grade Market Umbrellas use Heavy Duty Pengi Marine Grade Solution Dyed Acrylic Fabric, covered by a 6- year “no-fade” guarantee, for vibrant colors that will resist sun damage year after year.
