What Is A Bollard?

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

Today, the phrase bollard also describes many different structures utilized on streets, around buildings, and in landscaping. Based on 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. If the supply of former cannons was utilized up, similarly shaped iron castings were designed to match the same functions. Bollards have since become many varieties that are widely employed on roads, especially in urban areas, as well as outside supermarkets, restaurants, hotels, shops, government buildings and stadiums.

The most typical form 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 only simple posts, but also numerous decorative designs. Some feature square or rectangular cross-sections, but many are cylindrical, sometimes with a domed, angled, or flat cap. They are available in a selection of metallic, painted, and sturdy powder coat finishes.

Removable bollards are utilized where the requirement to limit access or direct traffic changes occasionally. Both retractable and fold-down styles are employed where selective entry is often needed, and therefore are designed therefore the bollard can be easily collapsed to ground level and quickly re-erected. Both retractable units could be manually operated or automated with hydraulic movements. Movable bollards are large, heavy objects – frequently stone or concrete – that depend on how much they weigh instead of structural anchoring to stay in place. They are designed to be moved rarely, then just with heavy machinery for instance a fork-lift.

Bollards generally fall under three varieties of applications:

Decorative Bollards – decorative bollards for architectural and/or landscaping highlights;

Traffic and Safety Bollards – bollards which provide asset and pedestrian safety, in addition to traffic direction; and

Decorative Bollards

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

Decorative bollards are produced to harmonize with both traditional and contemporary architectural styles. The latter lean toward visual simplicity – often straight-sided posts with several reveals close to the top. Styles made to match various historic periods normally have more elaborate shapes and surface details. Included in this are flutes, bands, scrolls along with other ornamentation.The post-top is a distinctive feature; traditional bollard design often includes elaborate decorative finials, whereas contemporary versions frequently feature a simple rounded or slanted top to deter passersby from leaving trash or making use of them for impromptu seating. On the other hand, these 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 frequently made of iron or aluminum casting. Aluminum bollards are desirable for applications where weight is a problem, such as a removable bollard. Aluminum units tend to be slightly more expensive than iron. For applications when a decorative bollard could be subject to destructive impact, ductile iron is a safer choice than more brittle metals, as force will deform the metal instead of shatter and transforming it into possible hazardous flying projectiles.

Iron and aluminum bollards are often manufactured by sand-casting – a traditional foundry technique that is certainly economical and well-suited 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 will machine 100% in the surface after casting to create units having a uniform surface for maximum visual appeal.

Finish is a crucial consideration in a decorative bollard, from functional in addition to aesthetic standpoints. Bollards are, by their nature, vulnerable to being scratched or nicked by pedestrians and vehicles. Those located near roadways are in contact with a relatively aggressive environment; petrochemical residues and splashes of diluted road de-icing salts may compromise wygcgg painted finishes. Factory-applied powder coating – which is available 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 method that completes the conclusion gives it additional toughness and abuse resistance.

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