Product Overview
Used in many architectural, commercial, and industrial applications, Grating Pacific’s durable, safe, and slip resistant stair treads are available in many styles.
Available in steel, aluminum, or stainless steel, treads are fabricated with a standard 1-1/4″ wide, visibly defined, slip-resistant nosing. Optional 2″ wide nosings are available for applications subject to California Title 24 and the California Building Code (must be specified at time of order).
Pre-punched end carrier plates or carrier angles facilitate prompt installation.
Types of Bar Grating Stair Treads
Steel Stair Treads
Steel grating stair treads are available in type “W” welded, type “SL” swage locked, or type “DT” dovetail pressure locked grating. Carrier plates are recommended for use with 19, 15, and 11 spaced gratings, while carrier angles are recommended for use with 8 and 7 spaced gratings. Nosing choices include checker plate, cast abrasive, FRP abrasive, and OnGrip surfaces.
