Details

The Perforated Square Tube support systems are designed to meet NCHRP 350 breakaway standards. In addition, the square design allows the user to easily install posts into the ground that would otherwise require digging or driving from a raised platform. Perforated Square Tube comes in widths from 1-1/2”, 1-3/4”, 2”, 2-1/4” and 2-1/2”. 7/16” Diameter holes on 1” hole centers. Galvanized steel conforming to ASTM Specification A653 DES G90.

In-line, galvanized zinc coating per AASHTO M-120, followed by a conversion coating and a clear organic topcoat. These different sizes allow different size pieces to be “sleeved” into one another. With this system, an anchor post (2-1/4” x 36” or 2-1/4” x 30”) is driven into the soil with a “drive cap” using a sledge hammer or power driver. The anchor post is left slightly above or flush with the ground. The installer can then insert a 2”x 10’ square tube (or any desired length) sign p ost into the 2-1/4” anchor post.Square Tube Signposts are stocked in 10 foot and 12 foot lengths. If you need to order another size, please call for assistance.10 Gauge = .135 Wall Thickness 12 Gauge = .105 Wall Thickness 14 Gauge = .083 Wall Thickness
