TradeReady® steel joists are one of the primary components that make up the TradeReady® floor system. These joists feature large extruded holes that accommodate HVAC, mechanical, plumbing and sprinkler runs. The joist also features a series of smaller holes for electrical and technology lines. TradeReady® steel joists are precision manufactured from corrosion-resistant galvanized steel. Steel joists offer consistent quality, predictable performance and high strength to weight ratio, and they are dimensionally stable. They won’t expand, contract or shrink; they won’t warp, crack or twist. Steel joists integrate easily with other building materials such as structural steel, concrete, ICF and wood construction.
