Bollards For Sale – It’s Worthwhile To Understand This..

Bollards are used in a multitude of applications, for one of various purposes. One needs only to keep a sharp eye to see bollards around us each day. In parking lots, driveways, and drive-thru lanes, bollards are used to protect buildings, teller machines, utilities including gas meters, electrical equipment and fire hydrants, handicap parking signs, gate entry keypads, and to restrict usage of undesired areas. In factories and warehouses, bollards are very important for protecting pedestrians in addition to guarding storage racks and capital equipment from fork truck collisions.

Other industries which locate a heavy use of decorative bollards include automated car wash facilities, self-storage facilities, gasoline stations and convenience stores, propane dispensing, and parking garages, and others.

Foundation mounted bollards are generally placed in certainly one of two ways. The very first, most affordable way, is to use a plate mounted bollard. These bollards are steel pipes welded to some flat steel plate that may be anchored to some hard surface using concrete anchors. This technique of installation is quick and inexpensive, requiring the installer to drill four to eight holes inside the concrete and bolt along the bollard with expansion or screw anchors.

The downside for this installation method, when used in combination with a rigid bollard, is the fact that anchors are generally not strong enough to withstand anything greater than a minor collision. The plate anchors often are pulled up and perhaps the plate bends, leaving a post which leans and is no longer in a position to properly serve its purpose. Plate mounted bollards often require constant maintenance and replacement.

The second technique for installing bollards involves employing a longer steel pipe and burying a portion of this deep in the earth. This technique affords the bollard much more strength than surface mounted, however it may be very costly to install if the surface is concrete and already poured. Installation in this case requires coring a hole within the surface employing an expensive diamond bladed coring saw. These machines as well as their blades are expensive and require water cooling, developing a mess during installation. When the concrete is cored and the bollard is within place, the hole has to be backfilled with concrete to secure the bollard. For added strength, these bollards are frequently filled with concrete, too. Though the bollard pipe is comparatively cheap, this installation strategy is costly and time intensive.

Although very strong, you can find significant disadvantages to core installations. Most significantly, there is not any share with this system upon impact. Though desired in high security applications, any vehicle impacting this type of bollard will be significantly damaged along with its passengers vulnerable to injury. Loads carried by fork trucks can also be thrown because of the jarring impact likely to occur. Further, the bollard or its foundation may be damaged by such an impact, again leaving a tilted and much less effective barrier requiring costly maintenance to correct. Frequently the steel bollard itself is beyond repair and must be replaced with the entirely new bollard.

Another drawback to this kind of installation is that it is a permanent installation with little flexibility for movement. In factory applications, devices are often moved and rearranged. Bollards employed to protect equipment or storage racks which are core-installed usually are not easily moved. The concrete around the bollard must be broken out as well as the large remaining hole filled, leaving a factory floor full of unsightly patches. If the bollard itself is reusable after removal, the whole expensive installation process is started over at the new location.

Some designs happen to be created to try to solve these issues through the use of plastic or spring loaded bollards, however these designs are afflicted by an absence of strength. In the event the plastic is of insufficient stiffness, the whole function of access denial is lost. On the contrary, very stiff plastic designs have gotten difficulty with long-term durability. Minor collisions have a tendency to wear away at such devices, as well as in outdoor applications UV degradation becomes a concern.

Designed and patented in Europe by Belgian inventor Gerard Wolters is actually a unique system which solves lots of the problems connected with traditional foundation mounted bollards. To put it simply, the program utilizes a compressed rubber base to act as an energy absorbing mass. This elastomer allows the bollard to tilt slightly when impacted, in all the different 20 degrees from vertical, then return upright while still stopping the colliding vehicle.

This technique is attached to concrete using concrete anchor screws. These anchors affix the base component within the adapter, which pre-compresses the elastomer from the ground. The base and adapter pieces are made from a special ductile cast iron, making the pieces less brittle than typical cast iron, and has a really low (-40 degrees) brittleness temperature. The steel pipe which serves as the bollard post is actually a typical steel pipe inserted to the adapter. Standard pipe can be used to offer the conclusion user the flexibility to weld fencing using standard components if needed. Concrete fill is not required inside the bollard pipe, though is permitted. Actually, sign posts may be inserted in to the post and concrete filled in place.

Upon collision, the pipe and adapter are permitted to tilt inside the base, forcing the adapter to advance compress the elastomer toward the impact. The elastomer absorbs much of the energy in the impact and lengthens the deceleration duration of the automobile. The elastomer is of sufficient strength to then rebound, usually pushing the vehicle out of the bollard and returning to a vertical position. The tilt of the pipe is limited to approximately 20 degrees at which point the bollard can become rigid.

Bollards are made in a variety of sizes, every one of that is right for various expected collision speeds and masses. Further, modular connectors which can be used to create fencing and guards away from multiple base units have already been designed to eliminate welding. By using multiple base units, the ultimate strength of the rebounding bollard unit could be increased.

These new bollards utilize the much simpler method of surface installation, greatly reducing installation costs, while maintaining the flexibleness to move bollards as conditions warrant. This is accomplished with no normal disadvantage of absence of strength, because the elastomer in the bollard system greatly cuts down on the maximum impact forces applied to the base anchors. The reason being deceleration of an impacting vehicle is much less severe than throughout an impact having a rigid bollard. Energy is transferred to the elastomer instead of right to a rigid post, reducing the harsh impact of a relatively immovable object.

This leads straight to the most significant benefits of the brand new bollard system and that is certainly the lowering of damage to both offending vehicles and to the bollard system itself. Direct injury to vehicles is reduced due to the reduction of peak impact force seen from the vehicle. Not only will this avoid harm to the vehicle, but also the chance of trouble for a passenger is likewise reduced. In the case of a fork lift in a factory or warehouse, the chance of a thrown load is additionally reduced, avoiding the potential for bystander injury and stock loss.

Finally, damage to the bollard and its foundation is reduced. Since the post is constructed of strong steel pipe, it maintains its strength, but due to its forgiving nature, a lot less force is moved to the building blocks. This simplifies and eliminates maintenance while preserving an great looking facility.

These bollards has to be placed on concrete, as an asphalt surface will not be of adequate strength to anchor the bollard system. Taking into consideration the replacement costs of damaged bollards, however, it may be cost effective to pour a concrete pad and eliminate many years of costly maintenance and asphalt repair. As previously mentioned, each bollard is sized for expected loads in terms of mass and speed. Should that limitation be exceeded, it really is easy to break a part of the program. Most likely that concerns the post, adapter, or base. Fortunately, the system is modular and easily repaired. Posts could be replaced by loosening several set-screws, wwbpkl and replacing, and re-tightening the set screws. Adapter and Base components can be replaced by carefully taking out the concrete screw anchors and replacing the component.

The SlowStop Bollard system is a revolutionary cool product which solves most of the problems included in bollard collisions as well as installation and maintenance issues. Injury to vehicles, passengers, vehicle loads, as well as the locking bollards themselves is cut down tremendously because of the absorption of impact energy by an elastomer hidden inside the lower bollard. This elastomer allows the bollard to tilt when impacted and return upright afterward. SlowStop Bollards are fast and inexpensive to put in, flexible since they are easily moved, and uncomplicated to keep up should there be the need. Safety fencing and barriers are easily created using modular connectors, avoiding the requirement to weld pipe together.
