Heavy Duty Range of Traffic Barrier, Bollards & Fencing

OSA has been manufacturing its Heavy duty range of traffic control products for many years yet the popularity of this product has been increasing, not decreasing.

Traffic Control Products

Bollards
Bollards with a cross section of 190x90mm are available in heights 1.2m, 1.5m and 1.8m. See below left.

Some clients ask us to customise the design and produce a design which is only available to them. We are happy to accommodate this. Bollards 1.2m long are normally available ex. stock.

Galvanised Bases for lift out bollards are available. See below right.

Specify: OSA Bollard 12, OSA bollard 15, OSA Bollard 18

Traffic Barrier
Posts matching the bollards are fabricated with a 195x45 hole straight through the post to receive the rail.

The rail is 190x44mm and the standard length is 3.6 metres. They are machined with a rounded top to shed water.

Where a shorter rail is required a 2.7 metre length of the same profile can be substituted from our two rail fence system. A neater finish can be achieved by using blanking ends at the end of a run.

Free standing sets are also available. The rail is normally 3.6m and the protrusion should not extend more than 450mm.
