One of the main benefits of U-channel sign posts is that installation of signs can be done at any height because of perforated holes along the entire length of the post. Unlike round and square posts, there is no need to dig a hole in the ground first to mount U-channel posts. The design of a U channel post is such that it withstands rough use and weathering. Also these are more affordable post options.
Our U channel sign post kit contains everything you need to mount a sign i.e. a U-Channel Post, two bolts (5/16" x 2"), two nuts, two metal lock washers and two plastic washers. All sized posts (3, 4, 5, 6, 7, and 8 feet) are offered individually as well as in kits. Choosing a kit over individual posts saves you a lot of time and money.
Economy and municipal quality U-channel posts mostly differ in their weights. Ideal for private parking lots and indoors, economy posts weigh 1.12 lbs per foot while municipal quality sign posts weigh 2 lbs per foot. Municipal posts are 3-1/16" wide whereas economy posts are a little narrower (2-1/4"). Municipal quality posts are heavy duty and are a standard at municipalities. These are ideal for traffic signs, signs measuring 18” x 24” and larger.
The amount of sign post that should be buried inside depends on the length of the post. For example, a 4-foot sign post should be inserted 1.5 feet inside the ground, while an 8 to 10-foot post should be set 3.5 feet under the ground. Ideally, one-third of the post should be fixed below the ground.
The galvanized finish offers more resistance against rust as compared to baked enamel coating. Galvanized posts are a better option in terms of durability. A typical galvanized U channel sign post lasts at least 10 years outdoors. Galvanized U channel posts are made of steel and protected by a rustproof zinc barrier. Even when the sign posts are nicked or chipped, they do not rust and last for years.
18” + 6” = 24 inches. So, you have a total sign height of 24 inches or let’s say 2 feet. You can combine two 6 feet sign posts to give you 7 feet height between the bottom of supplemental sign and the ground.
An 8 feet post will give you about 5 feet of distance between the ground and the bottom of a parking sign because at least 3 feet goes under the ground.
