What Is A Bollard?

A bollard is actually a short vertical post. Early bollards were for mooring large ships at dock, plus they are still in use today. A typical marine bollard is created in cast iron or steel and shaped somewhat just like a mushroom; the enlarged top is designed to prevent mooring ropes from slipping off.

Today, the word bollard also describes a variety of structures used on streets, around buildings, and in landscaping. In accordance with legend, the initial street bollards were actually cannons – sometimes reported to be captured enemy weapons – planted in the earth as boundary posts and town markers. Once the supply of former cannons was utilized up, similarly shaped iron castings were made to fulfill the same functions. Bollards have since evolved into many varieties which can be widely employed on roads, specifically in urban areas, along with outside supermarkets, restaurants, hotels, shops, government buildings and stadiums.

The most common type of bollard is fixed. The easiest is definitely an unaesthetic steel post, about 914 to 1219 mm (36 to 48 in.) above-grade. Specially manufactured bollards include not just simple posts, but additionally numerous decorative designs.

Removable bollards are utilized where the necessity to limit access or direct traffic changes occasionally. Both retractable and fold-down styles are employed where selective entry is frequently needed, and therefore are designed and so the bollard can easily be collapsed to ground level and quickly re-erected. Both retractable units might be manually operated or automated with hydraulic movements. Movable bollards are large, heavy objects – frequently stone or concrete – that count on their weight rather than structural anchoring to stay in place. They are created to be moved rarely, then just with heavy machinery for instance a fork-lift.

Bollards generally fall into three types of applications:

Decorative Bollards – decorative bollards for architectural or landscaping highlights;

Traffic and Safety Bollards – bollards that provide asset and pedestrian safety, as well as traffic direction; and

Decorative Bollards

Some bollards are intended purely to get an ornament. As standalone architectural or landscaping features, they could border, divide, or define a place. They can also be accents, sentries, or supporting players to larger, more dramatic architectural gesture.

Decorative bollards are made to harmonize with both traditional and contemporary architectural styles. The second lean toward visual simplicity – often straight-sided posts with a number of reveals near the top. Styles created to match various historic periods will often have more elaborate shapes and surface details. Included in this are flutes, bands, scrolls and other ornamentation.The post-top is really a distinctive feature; traditional bollard design often includes elaborate decorative finials, whereas contemporary versions frequently come with a simple rounded or slanted top to discourage passersby from leaving trash or utilizing them for impromptu seating. On the other hand, they are sometimes made flat and broad specifically to encourage seating. Common decorative bollard materials include iron, aluminum, stainless steel, and concrete.

Ornamental designs with elaborate detail are usually made from iron or aluminum casting. Aluminum bollards are desirable for applications where weight is an issue, such as a removable bollard. Aluminum units are usually a little more expensive than iron. For applications when a decorative bollard could be subjected to destructive impact, ductile iron is really a safer choice than more brittle metals, as force will deform the metal as opposed to shatter and transforming it into possible hazardous flying projectiles.

Iron and aluminum bollards are frequently manufactured by sand-casting – a traditional foundry technique that is economical and well-fitted to objects this size. However, sand-cast objects frequently bear surface irregularities that tend to leave the finished product less appealing to the attention. If high-finish consistency is desired, seek a manufacturer that can machine 100% from the surface after casting to create units having a uniform surface for max appearance.

Finish is an important consideration in a decorative bollard, from functional in addition to aesthetic standpoints. Bollards are, by their nature, prone to being scratched or nicked by pedestrians and vehicles. Those located near roadways are subjected to a reasonably aggressive environment; petrochemical residues and splashes of diluted road de-icing salts may compromise wygcgg painted finishes. Factory-applied powder coating – that is on iron, aluminum, and steel – is definitely an especially durable form of painted finish. The application form process builds a coating with very consistent coverage. During coating, any bare metal has a tendency to attract the powder, eliminating pinholes in coverage. The baking procedure that completes the conclusion gives it additional toughness and abuse resistance.

In applications where greater physical abuse is predictable, decorative bollards made of aluminum might be a better option than iron. In the event the finish coat is damaged, aluminum oxidizes to some color that is generally more acceptable than the red rust produced by iron. Aluminum and stainless-steel are also available in a variety of bare metal finishes. Functionality can be put into the otherwise decorative bollard. For example, common choice is the chain eye – linking 2 or more bollards with chain, developing a simple traffic direction system. A sizable metal loop or arm on the side of the post allows parking and locking of bicycles, a progressively popular choice as more people seek alternative green transportation. Bollards may also contain lighting units or security devices, like motion sensors or cameras.
