A Traffic Sign is Commonly Mounted on a Single Square Tubing Sign Post

The most typical square tube widths we sell are 1.5", 1.75", and 2". The vast majority of traffic signs are manufactured out of .080 aluminum - that's just eight one-hundredths of an inch! - with two holes, on center, for mounting to your sign post. The traffic sign sizes we sell most frequently are 12" x 18", 24" x 24", 36" x 36", and 48" x 48". That's quite a range in surface area!

How to Measure the Surface Area of a Traffic Sign

Multiply the width (in inches) by the height (in inches) and then divide by 144 (12" x 12" = 144" - or one square foot)

  • A 12" x 18" sign covers 1.5 square feet
  • A 48" x 48" sign covers 16 square feet

Both of these signs are mounted exactly the  same way, attached to a single sign post - that's maybe 2" wide - with 2 bolts or drive rivets, right through the center of the sign. One near the top and one near the bottom.

It has a relatively small surface area. But, with 16 square feet of area for the wind to target, that 48" sign has the potential to wind up folded in half around the post, like the lid of a sardine can, rendering it useless to motorists, since they will no longer be able to see or read it. That doesn't sound safe.

Luckily, there is a simple solution.
