Quiet as a traditional TJI floor, greater load capacity Up to five times stiffer than either wood or other steel systems Less expensive than both wood floors and other steel floors    Main beams and purlins are at the same elevation to reduce the total section depth. All welding is done by our certified welders The joist is screwed not shot to the beam for strength. A high density rubber pad isolates the joist from the beam to eliminate vibration We use a 6” 18 ga galvanized joist at 16” on center to produce deflection of L/2400!! Purlins rest in angle iron wall connections Unlike any other steel floor, this System is both strong and quiet. No vibration, no noise – period! Click here for larger size

General Description: The floor is constructed using a combination of steel components aligned in opposing directions to produce high diaphragm strength and low deflection. No other steel framed floor system is as strong or as quiet. This design criteria results in a floor that is indistinguishable in every respect from the main level wood framed floor.  The steel frame is decked with conventional 23/32” T & G OSB producing a finish floor elevation just over 23” above basement sub-grade. Conventional wood floor systems and other steel systems typically require more clearance and reduce available ceiling height accordingly. Materials: Main Beams – 10” or 8” deep beams as sized by our engineers supported by wall mounted angle iron beam saddles and supported mid span by either 3” SCH 40 mono posts or 3” x 3” x1/4” tube steel posts anchored to the top of the concrete piers. Purlins – 10” or 8” deep beams as sized by our engineers running perpendicular to the main beams at 8’0” on center welded to the main beam and supported at the side wall with a purlin bracket. The top of the purlins and main beam are at the same elevation. Joists – 6” 18 ga. x 1-5/8” joists (600XC18) running parallel to the main beams are mounted over the steel sub-frame at 16” on center. Joists are fastened to the beams below with self tapping screws to 6” 18 ga. track mounted on the end walls. Decking – 23/32” T&G OSB by Louisiana Pacific or Weyerhauser. Fastened to joists with 15/16” deck screws. Vibration Isolation – “Quiet Core” foam pad between purlins and joists Design Criteria:  Dead Load 10#/sf  Live Load 40#/sf Actual Deflection: Total Load L/2571 (Maximum Deflection 0.037 inch) Live Load L/1889 (Maximum Deflection 0.051 inch) Source: Clark Western AISIWIN Pricing: Less than a comparable wood or competitive steel framed floor systems.  Significant discounts are available for production and volume.
