Sign Installation
Every sign installation is different. The information on this page is to help you determine what is best for your sign installation situation. The photos provided are to help you and show you how our customers are installing their signs. Wood Product Signs does not install signs, we can provide posts for your signs when available. The information below is for recycled plastic signs, however some information may apply to our wood signs. We strongly recommend reading the information below if you have purchased or are considering purchasing a recycled plastic sign.
Expansion and Contraction
Due to fluctuation in weather temperatures this HDPE recycled plastic sign material will expand or contract at a maximum rate of .03" per foot depending on sign color selected. Installation design considerations must be applied in order to compensate for sign material expansion or contraction.
This material must have room to move freely.

Oversize All Drill Holes in HDPE Signs
All holes drilled must be oversized a minimum of 1/8 " to 1/4" than the bolt used. (This is to prevent the sign from cracking.) Use of bolts/fasteners is recommended and they should be loosely fastened to allow movement of expansion or contraction. DO NOT over tighten bolts! The recycled plastic sign material is very easy to drill. Recycled Plastic signs do not come pre-drilled.

Use Wood Crosspieces
We highly recommend mounting all hdpe recycled plastic signs to wood posts and using 2 or more wood crosspieces depending on the size of the sign. The maximum space between the crosspieces should be no more then 3 1/2 feet.
Deck screws may be used to attach the crosspieces to the sign, these holes do not have to be oversized. 12" - 18" is recommended for spacing of the deck screws.

Framework
If you are installing your sign into framework, please allow 1/4 " - 3/8" room
on each side of the sign to allow for expansion and contraction.
Do not trap your sign tightly into the framework.
*This also applies to 1 panel or 2 panel (spliced) signs.

Spliced Signs

If your sign contains 2 or more panels we recommend to use wood crosspieces across the splice of the sign for stability.

Failure to properly install your new recycled plastic sign may put excessive stress on the
sign and may result in warping or cracking.
