The choice between a flexible bollard and a rigid kerb or bollard essentially comes down to how often the protected zone is expected to be hit. As soon as a traffic point faces regular scraping or impacts, whether from forklift manoeuvres in a warehouse, vehicles cutting a corner in a car park, or building site machinery operating close by, the flexibility of the unit completely changes the economics. A rigid bollard cracks or works loose after a few impacts and needs replacing, whereas a flexible model absorbs the impact and keeps working with no intervention needed. In low-impact-risk areas, on the other hand, a conventional fixed unit remains a sensible choice and avoids over-investing in a technical solution whose flexibility would never be called upon.
Spacing and layout for an effective line of delineators
The effectiveness of a line of delineators depends as much on the spacing between units as on the model chosen. Spacing that is too wide lets a vehicle pass between two units without touching them, cancelling out the intended deterrent effect, while spacing that is too tight unnecessarily increases the number of units and the installation cost. On a warehouse traffic aisle, positioning delineators slightly back from manoeuvring corners prevents them from being struck systematically during tight forklift turns, extending their useful service life even under flexible-duty conditions.
Ground fixing: planning for the existing surface
The type of ground directly determines the fixing method used. A concrete slab in good condition accepts a standard bolted fixing, the most stable option for intensive use. On a thinner asphalt surface, a fragile industrial floor covering or an area where the fixing should not be permanent, a weighted or removable base avoids damaging the ground while still offering good resistance to side impacts. Checking the nature of the surface before choosing the fixing method avoids the base coming loose prematurely, the most common cause of early replacement.
Maintenance and service life under heavy use
The flexible material forming the body of the delineator remains exposed to UV, to hydrocarbons in a logistics environment, and to abrasion from repeated impacts. A periodic visual check helps spot the start of cracking or a loss of elasticity before it compromises the unit's ability to spring back upright after an impact. Regular cleaning of the reflective bands also keeps them effective at night, a point that is often overlooked despite directly affecting safety in a vehicle traffic zone.
Mistakes to avoid during deployment
Several mistakes crop up repeatedly when installing flexible delineators at a logistics site or car park:
- Choosing a height that is insufficient for night-time driver visibility, particularly in poorly lit areas
- Fitting a permanent model in a zone whose traffic layout changes regularly
- Underestimating the actual frequency of impacts and defaulting to a rigid solution out of habit rather than site analysis
- Overlooking the spacing between units, which determines the real effectiveness of the system far more than the total number installed
Planning ahead, with consistent spacing and a fixing method suited to the ground, ensures a flexible delineator that stays effective over time without multiple replacements caused by wear or poorly anticipated impacts.
