What Is A Bollard?

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

Today, the term bollard also describes a number of structures used on streets, around buildings, and then in landscaping. Based on legend, the very first street bollards were actually cannons – sometimes reported to be captured enemy weapons – planted in the ground as boundary posts and town markers. Once the availability of former cannons was applied up, similarly shaped iron castings were designed to match the same functions. Bollards have since evolved into many varieties which can be widely employed on roads, especially in urban areas, in addition to outside supermarkets, restaurants, hotels, shops, government buildings and stadiums.

Both retractable units might be manually operated or automated with hydraulic movements. Movable bollards are large, heavy objects – frequently stone or concrete – that rely on how much they weigh as opposed to structural anchoring to remain in place.

Decorative Bollards

Some bollards are intended purely to become an ornament. As standalone architectural or landscaping features, they could border, divide, or define an area. They may 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 latter lean toward visual simplicity – often straight-sided posts with a number of reveals nearby the top. Styles made to match various historic periods normally have more elaborate shapes and surface details. Such as flutes, bands, scrolls as well as other ornamentation.The post-top is a distinctive feature; traditional bollard design often includes elaborate decorative finials, whereas contemporary versions frequently include a simple rounded or slanted top to discourage passersby from leaving trash or making use of them for impromptu seating. On the contrary, they may be sometimes made flat and broad specifically to encourage seating. Common decorative bollard materials include iron, aluminum, stainless, and concrete.

Ornamental designs with elaborate detail are frequently made of iron or aluminum casting. Aluminum bollards are desirable for applications where weight is an issue, such as a removable bollard. Aluminum units are generally slightly more expensive than iron. For applications where a decorative bollard might 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 usually manufactured by sand-casting – a regular foundry technique that is certainly economical and well-suited to objects this size. However, sand-cast objects frequently bear surface irregularities that often leave the finished product less popular with the attention. If high-finish consistency is desired, seek a manufacturer that can machine 100% in the surface after casting to generate units having a uniform surface for optimum appearance.

Finish is a crucial consideration in a decorative bollard, from functional as well as aesthetic standpoints. Bollards are, by their nature, prone 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 – that is on iron, aluminum, and steel – is surely an especially durable kind of painted finish. The application form process builds up a coating with very consistent coverage. During coating, any bare metal has a tendency to attract the powder, eliminating pinholes in coverage. The baking process that completes the finish gives it additional toughness and abuse resistance.

In applications where greater physical abuse is predictable, decorative bollards manufactured from aluminum might be a better option than iron. When the finish coat is damaged, aluminum oxidizes to some color which is generally more acceptable compared to the red rust created by iron. Aluminum and stainless are also available in a number of bare metal finishes. Functionality may be included in the otherwise decorative bollard. As an example, common option is the chain eye – linking 2 or more bollards with chain, creating a simple traffic direction system. A large metal loop or arm on the side from the post allows parking and locking of bicycles, an extremely popular choice as increasing numbers of people seek alternative green transportation. Bollards may also contain lighting units or security devices, including motion sensors or cameras.
