The Ins and Outs of Bollards

Are you considering the installation of bollards to protect your business premises?   Here is some information on what bollards do and key considerations before moving forward with this security measure: 

How to Choose a Bollard for Your Purposes 

If the bollards are for security or protection, a strengthened impact-absorbing bollard would be the ideal choice as they provide the necessary strength and resilience. Asset protection bollards for banks, ATM’s, government assets and high risk buildings are more commonly filled with an anti-cutting and an anti-ram raid concrete like mixture. They are very heavy and have been known to stop heavy vehicles in an attack. They take longer to cut through making the risks higher for the perpetrator and therefore tend rarely to be attacked. 

These heavy bollards can also be used in glass shop fronts and warehouse door applications. In the warehouse roller door situation, have them close enough to the door to allow the locking cabling system (that most providers can install) to stop the doors being broken and pulled up. 

These bollards also come in a base plate model bolted into the ground but are less effective than the core drilled models. Other applications suitable for this bollard are where break-ins, vehicle theft or unauthorised parking are a risk or you wish to deter obstruction of driveway access or emergency exits. 

These bollards can also be removable but you will require a specially designed trolley that will be an extra cost alongside the cost of the bollard itself. Some consider these bollards to be aesthetically poor, so many councils and shopping centres have turned to using large pot plants. 

These are not easily removable and in some circumstances the pots have bollards concealed within them for added protection. For decorative use on the streetscape or in a public venue, a more stylish bollard that is less intrusive would be the best choice. Cast aluminium with a powder-coated finish can add colour and life to an otherwise dull bollard. When placed in a public venue or park where vehicular access is undesirable, then a sturdy cast aluminium or stainless steel tubular bollard would do perfectly as you wish only to stop accidental entry. 

Considerations Prior to Installation 

Will the bollards need to be removed at any stage to allow access? Are they positioned at least 1.4 m apart (inside to inside) to effectively repel an attack? If core drilled, do you have access of 600 l x 600 w x 600 d below ground for each bollard? What is under the concrete slab, pavers or terrazzo floor?  It may be necessary to have the floor x-rayed and cleared by a engineer to rule out gas lines, electricity cables, telecoms cables, reinforcing steel mesh or water mains.
