About this file
This document is a Louisiana Department of Transportation and Development (DOTD) specification for aluminum extruded supports and stiffeners, specifically detailing three product types for sign installation and mounting. The products include Product ID 53051 (Extruded Aluminum Sign Backing Channel), Product ID 53052 (T-shaped Extruded Aluminum Stiffener with Track), and Product ID 53053 (T-shaped Extruded Aluminum Stiffener without Track). Each product has specific dimensional requirements, with lengths ranging from 9' to 12' and variations in width and thickness.
The specifications require the supports to be manufactured from aluminum alloy 6061-T6, anodized to produce a corrosion-resistant aluminum oxide coating in conformance with ASTM B449, Class 1 or 2. Delivery requirements mandate that supports must be shipped in securely banded bundles of no more than 50 pieces per product ID, transported via open bed truck and tarped during shipment. A certification letter from the manufacturer must accompany each shipment, which will be kept on file by the Department. Product dimensions are allowed a variance of ± 1/8 inch from the attached technical drawings, and all supports must be free of grease, dirt, and loose phosphate coating with burrs removed from edges.
