A unique signpost using tubular steel was observed at one of our projects. We did some investigation on installation and cost. An Internet steel supplier has 12” by 4” rectangular tubes in 10-foot lengths for $387 before tax and shipping. The Zimmer standard is a 2” by 2” square post inserted into a 6-inch diameter pipe and embedded in concrete. The pipe is covered with a plastic sleeve. Depending on the number of signs to be installed, the cost ranges from $800 to $1,750. The rectangular tube design is less involved could cost less than $800 installed. We’d recommend galvanizing the tube rather than painting, to minimize future maintenance costs.
