What Is A Bollard?

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

Today, the phrase bollard also describes many different structures utilized on streets, around buildings, and then in landscaping. Based on legend, the very first street bollards were actually cannons – sometimes said to be captured enemy weapons – planted in the earth as boundary posts and town markers. When the flow of former cannons was utilized up, similarly shaped iron castings were designed to fulfill the same functions. Bollards have since become many varieties which are widely employed on roads, particularly in urban areas, as well as outside supermarkets, restaurants, hotels, shops, government buildings and stadiums.

Both retractable units may 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. They are created to be moved rarely, and after that simply with heavy machinery like a fork-lift.

Decorative Bollards – decorative bollards for architectural and landscaping highlights;

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 can 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 several reveals nearby the top. Styles made 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 using 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 manufactured from iron or aluminum casting. Aluminum bollards are desirable for applications where weight is a concern, such as a removable bollard. Aluminum units are usually a little more expensive than iron. For applications when a decorative bollard could be subject to destructive impact, ductile iron is actually a safer choice than more brittle metals, as force will deform the metal rather than 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 certainly economical and well-suitable for objects this size. However, sand-cast objects frequently bear surface irregularities that tend to leave the finished product less attractive to the attention. If high-finish consistency is desired, seek a manufacturer that can machine 100% of the surface after casting to produce units having a uniform surface for max visual appeal.

Finish is a crucial consideration in a decorative bollard, from functional along with aesthetic standpoints. Bollards are, by their nature, susceptible to being scratched or nicked by pedestrians and vehicles. Those located near roadways are exposed to a fairly aggressive environment; petrochemical residues and splashes of diluted road de-icing salts may compromise wygcgg painted finishes. Factory-applied powder coating – which can be on iron, aluminum, and steel – is surely an especially durable kind of painted finish. The applying 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 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 can be a better option than iron. If the finish coat is damaged, aluminum oxidizes to your color that is certainly generally more acceptable compared to red rust created by iron. Aluminum and stainless can also be found in a quantity of bare metal finishes. Functionality could be included in the otherwise decorative bollard. For instance, common option is the chain eye – linking 2 or more bollards with chain, making a simple traffic direction system. A large metal loop or arm on the side from the post allows parking and locking of bicycles, an increasingly popular choice as more people seek alternative green transportation. Bollards could also contain lighting units or security devices, such as motion sensors or cameras.
