    Product Description

    Made to OSHA Guidelines for safety

    We manufacture the highest quality Warning signs made to the Occupational Safety and Health Administration's (OSHA) guidelines for safety control devices, Standards - 29 CFR, Part 1910.145. The stroke and spacing of the letter style along with the header for these Warning OSHA safety signs are designed and field-tested for maximum readability.

    These are the same signs used by professionals and government agencies.

    Material

    These safety signs are made from professional grade sign aluminum, finished with a painted enamel background that is baked on for long lasting durability. We use a .040 inch thick aluminum alloy that is long lasting and rust free even in harsh weather extremes. The sign can withstand temperatures from -40°F up to 160°F.

    Larger is more readable

    These safety signs also available in three sizes of 10W x 7H, 14W x 10H and 20W x 14H. The size of the sign required is a function of the viewing distance. A larger sign can be read from a further distance. The 10"W x 7"H can be viewed up to 12 feet, 14"W x 10"H can be viewed up to 18 feet, and a 20"W x 14"H can be viewed up to 25 feet.

    Holes in sign for easy mounting

    We also punch holes in the sign for easy mounting. The holes are 1/8 inch wide and are in the corner of the safety sign. The aluminum is cleaned and degreased, the corners are rounded, and the edges are smoothed to prevent injury.

    Green Policy

    ASTM 3105 aluminum is environmentally friendly because of its high recycled content; 24.86% post consumer, 65.2% secondary content and only 9.89% virgin aluminum ingots. Signs are recyclable and use recycled materials.
