Tips Buying a Bollard


Bollards, by their very nature are highly vulnerable to impact, yet surprisingly are not made impact resistant!             

 

This only serves to line the pockets of the concrete suppliers and bollard manufacturers as every time a bollard is badly impacted or grows unsafe it must be removed and replaced.This is costly cycle that over the life of a development costs thousands for every bollard and results in literally tonnes of carbon intensive landfill.

We have developed a range of solutions including Smart Sustainable Foundations and Smart Impact Recovery System ( In-ground and Surface Mount) making the foundations and the bollard removable and re-usable impact after impact). Options avaiable that will stop a vehicle in it's tracks (Anti-terrorist bollards or Ram-raid Bollards).  VIEW CATALOGUE

In-ground Bollards

In-ground bollards are costly to install and even more costly to maintain. Until now this was the only way to stop a vehicle- but now it is just wasteful. If damaged they cost around $600 - 1000 + to replace (including removal of damaged bollard and foundations and reinstatement of a new bollard and new foundations). The bollard shown below was damaged 6 times in one year (until the entire traffic island needed replacing) costing the state more than ten thousand dollars in a single year  and as it has been reinstated using the same method, the process will be repeated year after year for the life of the development (50 + years x $10,000 = $500,000.00 for this one bollard)

In-ground bollards can be made from galvanised steel (not black steel as it will rust), stainless steel pipe (not tube, as tube is not impact-resistant and more likely to rust and corrode than stainless steel pipe) or more recently plastic bollards have become very popular as they require less maintenance and improve safety.

When a solid in-ground bollard is impacted by a vehicle the force will bend a steel bollard at the surface (by filling the bollard with solid concrete, transfers the force to the foundations). To make a bollard capable of taking the impact force from a vehicle without dislodging the concrete foundations, you will need to install the bollard in a solid concrete (not rapid set) foundation around 600 mm deep x 400 mm x 400 mm wide but impact from a heavy vehicle can easily result in this sort of damage. Even though filling the bollard with concrete adds little strength in resisting impact, it helps the pipe itself resist collapsing at the point of impact.  

  

We have developed a simple, permanent solution

We are unique in that we would rather help you to build a more sustainable future than sell you bollards over and over again. To demonstrate this commitment we developed a simple means of making both your bollards and the surrounding concrete foundations re-usable impact, year after year. Used by all major cities in WA you will wonder how you ever did without this system!  Click here for details

Surface Mount Bollards

If your bollard is likely to be impacted by shopping trolleys we highly recommend using steel, stainless steel pipe (heavy duty) and securing the base plaste using impact resistant concrete anchors. If your bollard is likely to be impacted by vehicles we highly recommend using the Smart Impact Recovery System to secure your bollard

Shown here is brand new bollard- already damaged (first week lost its cap and base is bent- entire unit must be replaced and reinstalled).Using these is locations where they may be vulnerable to impact from vehicles only serves to line the pockets of the bollard manufacturers as every time a bollard is badly impacted or grows unsafe it must be removed and replaced. This is costly cycle that over the life of a development costs thousands for every location.

We have developed a simple solution. Secure bollard using impact resistant concrete anchors. For Large bollards (140 - 168 mm diameter) you can us the Impact Recovery system to make bollards impact resistant, removable and re-usable following severe impact. Click here for details


 

Designer Bollards


Generally used for deliniation and not subject to vehicle impact you have a range of options for this application, or we can design a bollard specifically for your project.

We produce a range of designer bollards in steel, aluminium, stainless steel and stone look highly durable plastic (also available in large range of colours). These bollards can be secured in-ground or surface mounted.

If bollards will be vulnerable to impact from vehicles, we would suggest securing your bollards on sustainable foundations (protecting both the bollard and surrounding foundations from damage). Click here for details

 

 

Carpark Bollards

Carpark bollards are highly vulnerable to impact so you want the material to be impact resistant (not light walled stainless steel tube).

For this application we would suggest using HD min 4 mm wall thickness Steel, or low Impact Plastic Bollards that are far less likely to be damaged when impacted by a vehicle.

For any bollard vulnerable to impact we highly suggest you use large 165 mm bollards and secure them on sustainable foundations using the Impact Recovery System to reduce impact force on the bollard and surrounding foundations.  Click here for details

We also recommend slightly taller bollards, in safety yellow, with reflective striping to improve visability. If you want fancy bollards you can use galvanised steel or poly Bollards

 

 

Industrial Bollards

 


For industrial applications bollards, can be made from galvanised steel, stainless steel pipe (which has a wall thickness of 3.4 mm, as opposed to stainless steel tube that has a thin wall of around 1.6 mm) or more recently plastic bollards have become very popular as they require less maintenance and improve safety.

Bollards can be installed directly in-ground or surface mounted but if you need to protect something from impact (such as a furnace, a valuable machine or people) from vehicle impact, we suggest you install your bollards directly in-ground in a solid 600 mm deep foundation. This will stop a vehicle in it’s tracks but will more often than not, cause damage to surrounding foundations and require replacing.  If bollard is to act as a deterrent to protect a building, we suggest bollards surface mounted, or installed in-ground using the Smart Impact Recovery system (bollard has a potential deflection zone of around 800 mm)

Bike Path Bollard

Solid steel bollards provide a dangerous obstacle for bike riders and createa dangerous litigation risk for local authorities. Surface mount bolalrds create dangerous trip factors adn often become unstable.

We have a permanent solution... For this application, we recommend Low Impact Safety Bollards. Made from polyethylene they are highly visible and highly durable, providing a low impact surface when compared to Steel and to further reduce risk of injury these bollards.

When impacted by bike rider, the bollard will absorb the impact force and slowly self-recover. If bollard is badly impacted by vehicle, foundations will remain undisturbed and the bollard can be easily removed and re-used. When bollard is removed, ground socket can be capped, leaving no trip factors. More Info

 

 

Disabled Bay Bollard

 

Disabled Bay bollards, we recommend our Safety Bollards (will not scratch vehicles) 1200 mm high in Highly visible safety Yellow with red reflectors.

In this location bollards are highly vulnerable to impact so for this application if you do not want to be spending money repeatedly replacing the bollard and the surrounding foundations, we would suggest using Impact Recovery Bollards.

These bollards will not deflect by hand but if impacted by a vehicle will deflect enough to absorb the impact force and preserve the surrounding foundations. If badly impacted the foundations remain undisturbed and the bollard becomes removable and re-usable time and time again. In-ground (150- 650 mm) or surface Mount options). More info

 

 

Traffic Bollard

 

Traffic bollards must be highly visible. They are vulnerable to impact from vehicles, often at high speed, so we do not recommend using heavy steel or concrete filled bollards that could cause serious injury.

Plastic surface mount bollards are a short term solution and a long term headache. They do little to prevent vehicle access and simply create costly maintenance.

We recommend small 60 mm diameter bollards secured on sustainable foundations (no damage or costly maintenance). These bollards are easily removable using tools, for wide loads, events or maintenance. Approved by Road authorities.

Bollard to stop a vehicle

For this application, we recommend 165 mm diameter steel pipe (5mm wall thickness) filled with concrete and installed a minimum of 600 mm in a solid concrete foundation.

We have developed a Smart Safety bollard that will preserve the foundations and be re-usable following impact.

At last there is a new type of bollard that offers the protection rivaling embedded bollard, while maintaining the integrity of the structural concrete.

The patented Impact Recovery System is a bollard that absorbs impacts using a unique energy absorbing ring hidden inside the bollard system. The Impact Recovery Ring allows the bollard to deflect approximately 20 degrees upon impact, then slowly return to upright. (In-ground & Surface Mount options available)

Calculating the size and configuration of bollards uses the speed and weight of the vehicle you’re trying to stop, the amount that a vehicle “crushes” to absorb the impact, and the flexibility of the barrier itself. In September 2010, Structure magazine published an article, “A Rational Method to Design Vehicular Barriers” that included an involved formula for measuring the force that a bollard needs to stop based on those factors.

The most important factor affecting the amount of force the car exerts is the vehicle speed — the force increases with the square of the speed of the vehicle. In configuring bollards, both the IBC and ASCE-7 set a design force for bollards that assumes a 6,500-pound vehicle traveling at 5 mph. Using a chart in the article, we can approximate an impact load of about 10,000 pounds at 5 mph.

Note that an unreinforced concrete post by itself, even at 8 inches in diameter, has little bending strength. In other words, a car running into it would easily break through it. That means an effective bollard must be steel — ideally a steel pipe filled with concrete. Even though the concrete adds little strength in resisting impact, it helps the pipe itself resist collapsing at the point of impact.

 

Caps

Aluminium designer caps come in a matt finish. To really brighten up your bollards we suggest having them polished and adding a small white reflective strip around insert.

 

Galvanised bollards

are suitable for industrial applications and can be powder coated almost any colour to improve appearance and durability. If you want a more aesthetic bollard you can use a designer cap.

A NEW alternative to powder coated bollards are plastic bollards. They look like powder coated bolalrds but are more sustainable (great for bollards that may be prone to being scuffed or scratched as plastic is the same colour and scratches do not show) They also provide a soft impact force reducing risk of injury or vehicle damage and come in many colours including stone look finish.

Stainless steel bollards

are generally satin finish (No.4. which is the most durable finish and doesn't mark as easily as a shiny finish does). See below for more information on this finish. Stainless steel can be made shiny by electroplating your bollards to an almost mirror finish. If you want a more aesthetic bollard you can use a designer cap

 

 

 

No 4: Finish

No 4 finish stainless steel is the easiest of the finishes to maintain, No 4 finish is used for work surfaces, handrails and where appearance is important.A 'No 4' surface is produced by cutting the surface with abrasive belts to remove a very small amount of metal without affecting its thickness.

For architects and designers, No 4 finish gives low gloss and best apparent flatness of panels.  For fabricators, the No 4 finish is directional, allowing easy matching of surfaces and refinishing of welds. For end users, the surface can be repaired to remove any service damage.

 

Corrosion Resistance

The corrosion resistance of a No 4 finish is usually lower than that of a mill finish on the same grade.Corrosion resistance may be reduced depending on the stainless steel grade used. By using grade 316 with a No 4 finish in aggressive environments, the corrosion resistance is negated and may be less than on 304 with a 2B or BA finish.

 Electropolishing the surface can also improve the corrosion resistance and brighten the surface. The peaks on the surface are smoothed, reducing the Ra value and increasing the reflectivity or gloss. The sulphide inclusions may also be removed or reduced.

 

Cleaning

No 4 finish can usually be kept clean by wiping down with a damp soft clean cloth. For grease, moisten the soft cloth with ammonia solution, or with one of the household liquid grease removers. Very hot water is also quite effective.
