Traction Tread® Specifications

Traction Tread® Safety Grating Specifications

Notes to architect

  1. Traction Tread® is intended for general purpose use in plants and process facilities by industry, commerce, and public facilities, for both mobile and stationary equipment.
  2. Traction Tread® stair treads are intended for utility stairs and fire escapes in commercial, public and private buildings where local code permits.
  3. These specifications are presented as a general guide to the architect or structural engineer in preparing project specifications.
  4. Allowable loads, spans and other limiting conditions presented in this catalog offer product data for use in design and construction.
  5. All supports should provide a smooth, level, 1 1/2” minimum bearing surface, free of burrs, bridging, welds or other irregularities.
  6. Random cut ends and diagonal or circular cut exposed edges should be banded with a bar at least 1 /8” thick and equal to the overall side channel depth of grating welded at contact points at the discretion of the design engineer.
  7. Bolted connections, except stair or ladder tread attachment to stringer channels, may be replaced by welded connections that develop the same strength.

Part 3: Execution

3.1 Condition of surfaces

Prior to Traction Tread® installation, contractor shall inspect supports for correct size, layout and alignment and verify thats urfaces
to receive grating are free of debris. The contractor shall report to the design or consulting engineer or ownesr’ agent in writing any
defects considered detrimental to proper application of traction tread so defects can be remedied before grating is applied.

3.2 Traction Tread® installation

Install TRACTION TREAD in accordance with manufacturer’s recommendations and shop drawings. Sheet goods by their nature are
intended to cover surface only. They require adequate support and hold down. Position traction tread planks flat and square with
ends bearing min. 11/2” on supporting structure. Keep traction tread sections at least 1/4” away from vertical steel sections and 1/2”
from concrete walls. Installation clearances are built into this product. Allow clearance at joints between sections of max1. /4” at side
channels and max. 3/8” at ends. When specified, band random cut ends and diagonal or circular cut exposed edges with a min.
1/8” thick bar welded at contact points.

3.3 Stair Tread Installation

Install Traction Tread® stair treads as shown on the drawings. Fasten treads to stair stringers with 3/8” x 1” machine bolts and nuts.

a. For stair treads, intermediate stringer is recommended for spans over 4 feet.
