What does MUTCD stand for?
The Manual of Uniform Traffic Control Devices is a manual that was written in 1935 to standardize road signage and make it uniform from state to state. Signage evolved through a combination of experiment, testing and much research. Through the year’s traffic sign sizes have changed, signs have been added, new reflective technologies have made signs much brighter and last longer. To learn more checkout the MUTCD website.

How deep should I pound my sign post?
Sign posts should be pounded 18” to 42” into the ground depending on the length of post, soil conditions, and how deep the frost line is in your area. Since burial guidelines vary from state to state we recommend reaching out to your local road department for their recommendation.
What type of Reflective Sheeting do you use?
Dornbos Sign & Safety has been using 3M Matched Component Products for over 60 years. Most signs available on our site are offered in a variety of reflective materials such as Engineer Grade Prismatic, High Intensity Prismatic, and Diamond Grade. Traffic signs meant for use on public roads must be High Intensity Prismatic or Diamond Grade reflective in order to meet MUTCD requirements for reflectivity.

When should I use 3M Diamond Grade Cubed Signs?
Local and state road agencies use 3M Diamond Grade Cubed Reflective sheeting when the MUTCD calls for it. Certain signs in the MUTCD and on certain signs and/or road projects might specifically call-out 3M Diamond Grade Cubed Reflective Sheeting.
FLOURESCENT YELLOW –GREEN TYPE XI is used for pedestrian and school crossings, school buses and building evacuation signs.

What is the difference between FLAT & EXTRUDED STREET SIGN?
FLAT street signs are made of our regular MUTCD compliant signs stock and are .080 thick 5052-H38 aluminum.
EXTRUDED street sign blanks have a thick ridge on the top and bottom of the sign blade and measures .090 thick between the ridges.
What liability do I have if my sign is fading and no longer reflective?
If your parking lot or road is “Open to Public Travel” your signs must follow the MUTCD standards for reflectivity. Roads that are built or maintained privately may not need to follow these guidelines. Installing the proper reflective signs is the best way to protect yourself from legal action.

- What is the difference between rail steel u-channel sign posts and billet steel u-channel sign post.
Answer. A lot of states, counties, and cities use U-CHANNEL SIGN POSTS. U-Channel Sign Posts are made of steel. DOT-Grade Rail Steel Sign Posts are made using either rail steel, from railroad tracks or BILLET STEEL. Billet steel is a semi-finished product that is formed by casting or continuous casting steel into long, square-shaped bars or rods. It serves as an intermediate product in the steelmaking process before being further processed into more specific shapes and sizes, such as bars, rods, or plates.
U-Channel Sign Posts from rail steel are 100% high-quality recycled rail steel. It is lightweight and long-lasting. Rail steel is a good choice for the harsh conditions of rain, salt, snow, and ice. Franklin Industries in Franklin Pennsylvania has been manufacturing quality u-channel signs posts since 1901. Dornbos Sign Inc. has been working with Franklin Industries for over 50 years.
