Save lost Aisle Space by using 11 1/2-inch wide seats and 12-inch high front row seat as allowed by most building codes.
The bleachers will be designed to support, in addition to their weight, a uniformly distributed live load of not less than 120 pounds per square foot of gross horizontal projection of the bleachers. All seat and foot plank members shall be designed to support not less than 125 pounds per linear foot, over a 6-foot span, multi-span condition. Bleachers shall be designed to resist, with or without live load, a horizontal wind load of 30 pounds per square foot of gross vertical projection. They shall be designed to resist, in addition to the live load, sway forces applied to the seats, in a direction parallel to the direction of the seat planks, 24 pounds per linear foot of seat plank, and separately, in a direction perpendicular to the direction of the seats, 10 pounds per linear foot of seat plank.
In the past bleacher guard rails usually consisted of a series of horizontal pipes or chainlink fencing attached around the seating perimeter to keep people from accidentally falling off the bleacher and being injured. Both horizontal pipes and chainlink fencing create a “ladder effect” and readily lend themselves to being climbed on. This activity can easily lead to unnecessary injury and liability. The possibility of accidents and serious injury and liability can be reduced by using vertical bar railings. This is part of Kay Park’s continuing effort to make good products even better. We urge you to plan your purchases on the side of safety.
4 Inch Spaced Vertical Bar Guard Rails (V4)
Kay Park’s engineers introduced vertical bar guard rails (Patented No. 404-141) to the outdoor portable bleacher industry, an innovation whose time had come. Vertical galvanized steel bars eliminate the “ladder effect” and a possible toe-hold for climbing on the guardrails.
Aluminum: Seat planks are 6063-T6 extruded aluminum which is clear anodized to standard 204-R1 specification. Standard 8″ rise per row uses 2”x10″ seats and new low rise 6″ rise uses 2″x12″ seats. Walk boards are 2″x10″ 6063-T6 extruded mill finish aluminum. End caps (anodized) and hold down clips are also extruded aluminum. Powder Coated Colors also available. Call for details
Wood: Seats and walk boards are 2″x10″ precision drilled, pressure treated and kiln dried specially selected No. 1, Southern Yellow Pine
Plastisol or Thermoplastic: in many colors (school colors etc.) can be applied to expanded metal for a more lively atmosphere.
BLG Series – Galvanized Steel Frame
Frames are fabricated from A36 alloy steel angles using full welds at all joints to give added strength. A combination of 2 x 2 x 3/16 inch and 1 3/4 x 1 3/4 x 3/16 inch angles are used, as required, for strength throughout each frame. Connecting “X” braces are 1 1/2 inch wide by 1/4 inch thick A36 alloy steel. For greatest protection and longest life, all parts are hot-dip galvanized after fabrication.
BLA Series – Aluminum Angle Frame
Frames are fabricated from 2 x 2 x 3/16 inch 6061-T6 alloy aluminum angles using a punched and bolted type construction for maximum strength and safety. All mainframe components are pre-assembled with large 1/2 inch diameter bolts, lock washers, and nuts. This bolted aluminum frame provides strong joints that will not develop weld cracks.
Full-Width Footboards with Riser Plank:
Many of the various recent codes for outdoor bleacher seating require any openings more than 30 inches above the ground be small enough so that a 4-inch sphere cannot pass through.
Kay Park has designed a new system using 2 footboards and one riser plate. This new system fills the space underneath the seats from the 4th row up to meet the 4-inch sphere guideline.
