Graduated Steel Tubing System
SportsPlay builds its modular playground components from a graduated family of steel tubing sizes it labels Type #1 through #5, ranging from 1 inch O.D. 14-gauge tube up to 2-3/8 inch O.D. 11-gauge tube, with each size assigned to specific structural roles like rungs, rails, or main support posts across its product line. Type #3 tubing is cross-hatched in a diamond pattern for improved hand grip on climbers.
The published specification sheets state that most tubing is FloCoat galvanized steel, produced through what SportsPlay describes as a patented in-line triple zinc coating process, which finishes the tube before fabrication rather than only coating it after welding. Components are then electrostatically powder-coated with an oven-cured polyester finish over the galvanized base.
This layered galvanize-then-powder-coat approach is a meaningful spec detail for New England buyers because it protects the steel at the cut edges and weld zones, the points most vulnerable to rust once a powder coat alone gets chipped by sledding, plows, or de-icing salt drift near equipment. It's the kind of underlying detail worth asking for on a bid spec rather than assuming from the color finish.
