Points to Consider When Choosing Sign Posts

Sign PostsSigns remind us where we are and where we are headed. Without signs, there would be utter chaos in the streets and highways. Navigation would be virtually impossible in our complex modern world.

Sign posts, bases and stanchions are just as important as the signs they hold up. Without proper accessories and hardware, your signs might just as well be as temporary as a cardboard marker that flies away with a sudden gust of wind.

Traffic Sign Posts

Road signs are especially vulnerable to weather conditions, graffiti, and accidents. You need strong sign posts that can withstand these elements if you don’t want to keep spending money trying to replace your signs.

According to the Manual of Standard Traffic Signs & Pavement Markings by the Ministry of Transportation and Highways in British Columbia, traffic sign posts may be made of wood, metal or plastic, though they recommend plastic be used for highway delineators only.

The ministry also recommends:

  • To position signs against the wind, plowed snow and be high enough to discourage displacement by vandals
  • To install signs behind barriers or breakaway footings to prevent vehicles from hitting them
  • To drill a hole through a 15 cm x 15 cm (6 sq in) post above ground to allow breakage if hit (in accordance with Standard Specifications for Highway Construction)
  • To check for underground utility lines before excavation
  • To ensure concrete sign bases are level and are behind roadside barriers
  • To install more than 1 post for large signs at least 1.2 me wide
  • To install uniform posts (same material and style) across highway sections for aesthetic purposes

Types of Sign Posts

The market offers a variety of sign posts to choose from. There are permanent posts that you can drive through the ground using a post driver and there are portable sign systems with stable bases you could position in different locations around your facility.

Permanent Sign Posts

There are different materials, sizes, and styles of permanent sign posts. There are u-channel posts which are made of perforated galvanized steel or dry coat steel, tubular posts made of rust-proof steel, and fixed-base posts that can be mounted on the ground using bolts.

Temporary Sign Posts

Portable sign posts can be made of rubber, cast iron, polyethylene, etc. These sign posts are especially useful for facility driveways and parking lots.

Flexible Sign Posts

Flexible sign posts are ideal for locations where vehicle impact is expected. These special posts bend and bounce right back up after contact with vehicles.


Sign PostsReflective Sign Posts

Reflective panels on posts and bases increase visibility that’s critical during low light and night time conditions. The reflectivity allows drivers to avoid hitting signs that may cause unnecessary damage to both vehicle and sign post.  Reflective sign post options are recommended for areas with high vehicular traffic.

Signs are incomplete without the proper sign posts to hold it up. Consider these points when choosing sign posts for your facilities, streets, or highways.
