Custom Street Signs

Official street signs are DOT-grade rustproof aluminum laminated with 3M retroreflective sheeting that meets ASTM D4956. The blank is.080-inch (80 mil) aluminum in a 5052-H38 or 3105-H191 alloy - the standard-duty gauge that stays rigid against wind load without oil-canning (warping). You can choose the reflectivity grade: Engineer Grade (Type I) for low-speed local roads, High Intensity Prismatic (Type IV) for brighter nighttime return, or Diamond Grade (Type XI) for the highest visibility. The sheeting carries a 3M 10-year warranty.

Letter height depends on the road under MUTCD Section 2D.06. Local roads at 25 mph or less can use 4-inch letters; the MUTCD recommends 6-inch letters for general use, multilane roads over 40 mph need 8-inch letters, and overhead signs use 12-inch letters. Taller letters read from farther away, which is why faster roads require them.

To install a street sign, you need a post and a matching bracket - round pipe, square, or U-channel, with a street-sign bracket sized to the post. MUTCD Section 2A.18 puts the bottom of the sign at least 7 feet above the curb in urban areas and at least 5 feet above the road surface in rural areas. Because the blade is double-sided, mounting it at an intersection allows it to be read from both directions.

Custom street signs ship in about 3 to 5 business days. The order is released to production the next business day after you approve the proof, then it's 3 to 5 business days in production before it goes to the carrier. Approving your proof quickly is the fastest way to move the order.

Yes - you can place a logo or pictograph to the left of the text on a D3-1 street name sign, following MUTCD Section 2D.43. The image should not exceed the uppercase letter height of the street name, so it stays balanced and legible.

MUTCD-compliant street name signs come in green, blue, brown, or white. Green, blue, and brown signs use white lettering; white signs use black. The color often signals the area - brown is common for parks and recreational districts, for example.

Official street signs are reflective, DOT-grade aluminum built to MUTCD standards for real roads and years of weather. Keepsake novelty signs share the classic look but are decorative - made for homes, garages, and offices as indoor or light-duty outdoor pieces, not road-legal signage.
