Road Flexi Post

Quick Answer: The Road Flexi Post is a flexible delineator post: a tall plastic post on a base fixed to the road, carrying reflective bands, that bends over when a vehicle hits it and springs back upright afterwards. The listing photograph shows orange-red posts with white or yellow bands.

Posts That Bend Instead of Break

Rigid bollards stop vehicles but can damage them, and they are costly to repair once hit. A flexi post is moulded from an elastic plastic that folds under a tyre or bumper and recovers its shape, so it can separate lanes, protect a footpath edge or narrow a road without becoming a hazard itself. Posts of this type are commonly made of polyurethane or a similar resilient plastic.

The coloured body and retroreflective bands make each post visible in daylight and in headlights, and a row of posts reads as a continuous line from a distance. In the photograph the posts carry either white or yellow bands; which colours go where is usually set by local road conventions. The base is normally bolted or bonded to the road, which lets the post stand firm yet flex.

Heights, base type and fixing kit are not given in the listing. Flexi posts are often combined with road studs along the same line, so drivers see the lane marking both at road level and at eye level.

Specifications

Where Flexi Posts Are Installed

• Separating entry and exit lanes at campus gates.
• Protecting pedestrian walkways and cycle lanes from vehicles.
• Narrowing roads to slow traffic near school entrances.
• Outlining parking area edges and turning islands.

Installation and Maintenance

• Install on a sound, clean surface and follow the fixing instructions supplied with the base.
• Inspect posts after impacts, and replace any that stay bent, have split or have lost reflective bands.
• Wash posts periodically to keep the reflective bands bright.
• Check base fixings for looseness, especially at busy entrances.

Why Choose LabEquip

Estates departments and campus contractors choose flexi posts to guide traffic without the vehicle damage that rigid bollards cause. LabEquip lists them in General Lab Products, and heights and colours can be discussed through the contact page.

Frequently Asked Questions

Will a flexi post stop a vehicle?

No. It is designed to guide traffic and bend if struck. Where vehicles must be physically stopped, for example to protect a building entrance, rigid bollards or barriers are needed.

What happens when a vehicle runs over a flexi post?

The post folds down and then recovers its upright position once the vehicle has passed. Repeated heavy impacts eventually leave it bent or split, and then it should be replaced.

How is a flexi post fixed?

The base is usually bolted into drilled holes or bonded to the surface with adhesive. A firm fixing is essential, because the post must flex around its base rather than tearing it loose.

What do the reflective bands do?

They are retroreflective and return headlight beams towards the driver, so the posts show up at night as bright bands in a line.

Can flexi posts be moved later?

Posts fixed to the road are semi-permanent. Some designs have a post that locks into a fixed base and can be lifted out to open the lane, so check the base design if you need that option.

Are flexi posts suitable near school gates?

Yes, they are often used to narrow the road, separate drop-off lanes and protect footpaths. Combine them with signs and markings so drivers understand the layout.
