How-To Articles and Informational Features related to Signs, Bollards, Installation and Tools.
A bollard barrier or barricade is a line of bollards installed to inhibit vehicles from from crossing the line, while still allowing passage of non-vehicular traffic, such as pedestrians on foot, or people in wheelchairs or delivery persons with carts etc. Often called Perimeter Security Bollard Systems, Bollard Barriers have a multitude of applications and range widely in vehicle stopping capability. Here, we are talking specifically about Building Entrance and Store Front Protection from both errant vehicles and ram-raids.

With the Dome-Top Bollard Cover, the minimum height, measured on the straight part of the cover wall, is the same as the height of the bollard pipe steel, from the ground to the top edge. The dome of the concrete (if any) will fit inside the dome of the cover.
Remove the backing on a strip of the neoprene tape. Wrap firmly around the top of post about 6″ from the top. Make sure to leave about a 1″ gap between ends of the tape to allow airflow while installing the cover. You can cut the tape as needed.
Rarely, pipe bollards are out of the ordinary. In most cases, you will have 4″, 5″, or 6″ Pipe. These have outer diameters (OD) of 4 1/2″, 5 9/16″ and 6 5/8″ respectively. Your measurements will very likely be close to one of those common pipes. See the chart below the next diagram for pipe and cover sizes.
Assembling Pyramid Bases is fairly self explanatory, but these instructions will help you get it right the first time.
We are laying out the costs associated with the installation of quantity 20 of the most common bollards in an existing asphalt parking lot. We hope this transparency will help you understand why they cost what they cost. By adding up these costs, we will arrive at a ROUGH estimate that should be useful to you if you are planning such a project.
Confused about Pipe Schedule vs Tube Gauge meanings? Confused as to why 6" Pipe does not have a 6" diameter? Nominal Size Nominal pipe sizes are given by their inner diameter (ID) while nominal round tube sizes are given by their outer diameter (OD). So a 6" inch pipe...
Have you ever used a post level? What a great tool. It has 2 wings on it so you can level the X-direction and the Y-direction at the same time. And it has a big rubber band that you use to attach it to the post.
