Same signs used by professionals
We manufacture the highest quality regulatory traffic signs made to the FHA guidelines (Federal Highway Administration) for traffic control devices. These R3-4 No U Turn Sign are professional sign grade aluminum, finished for long lasting performance and designed for easy detection, recognition, and legibility.
Long lasting and rust free
We use ASTM 3105 sign grade aluminum alloy that is long lasting and rust free even in harsh weather extremes. The heavy gauge sign grade aluminum is .080 inches thick and is not easily vandalized or bent. The aluminum is cleaned and degreased to ASTM B-499 specifications as pretreatment for sheeting applications. A chromic acid conversion coating is applied for weather resistance and the edges are smoothed to prevent injury.
The stroke and spacing of the letter style for these R3-4 No U Turn Sign are also designed and field-tested for maximum readability and conform to the design requirements of the Federal Highway Administrations Manual on Uniform Traffic Control Devices.
Reflective background - three options
All traffic signs must now be reflective, according to the Federal Highway Administration. The signs come in three grades of reflectivity (technically named retro reflectivity as a measure of reflecting light back to its source); Type I Engineer Grade, Type IV High Intensity Grade, and Type XI Diamond Grade. This product conforms to USDOT FHA standard specifications for construction of roads and bridges on federal highway projects, 1985 FP-85, Type II, Section 718.01. The reflective sheeting is chemical resistant and can withstand temperatures up to 160°F.
The Type I Engineer Grade Reflective is made from Nikkalite EG reflective sheeting. It exceeds ASTM D4956 Type 1 standards for retro reflectivity which is visible in daytime or nighttime from a wide range of angles. The reflective sheeting has 7 year durability.
The Type IV High Intensity Reflective is made from 3M Series 3930 and exceeds specification ASTM D 4956-04. It has a tougher topcoat that aids against scuffs and scratches. The vivid daytime colors provide 24 hour performance and the improved optical package increases nighttime visibility. The reflective sheeting has 10 year durability.
The Type XI Diamond Grade Reflective is made from 3M Series 4000 and exceeds specification ASTM Type XI proposed. It delivers optimal performance at all sight distances, as well as all light and weather conditions. It overcomes declining illumination from newer headlights, provides the level of luminance needed by older drivers, and accommodates drivers of larger vehicles. The reflective sheeting has 12 year durability.
Larger size is more readable
We offer signs in optional sizes. The size of the sign required is a function of speed and viewing distance. The faster a motorist is traveling then the further distance they will need to see the sign from. A larger sign can be read from a further distance. The MUTCD has correlated sign sizes by the type of road a motorist travels; Bike Path, Minimum, Standard, and Expressway.
For all roads open to public travel including parking lots
Title 23 of the Code of Federal Regulations, Part 655.603 states that for the purpose of MUTCD applicability, the phrase "open to public travel" includes toll roads and roads within shopping centers, parking lots, airports, sports arenas, and other similar business and recreation facilities that are privately owned but where the public is allowed to travel without access restrictions.
Holes in sign for easy mounting
We also punch holes in the sign for easy mounting. The holes are 3/8 inch wide and are centered in the middle of the sign, top and bottom. These holes match standard sign posts.
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. It can also be recycled for future use. Product life impacts the environment more than any other factor and this product is known for its reliability over competitor's products. This item is Made in America which reduces transportation costs, supply time and its environmental impact. Signs are recyclable and use recycled materials.
This item comes with a limited manufacturer's guarantee on the reflective sheeting. Product life listed above is for normal use.
This item is Made in America which reduces transportation costs, supply time and its environmental impact and keeps American jobs.
