The prominence of bollards has dramatically increased during the past decade due to heightened concerns about security. They are a simple, practical, and cost-effective way of erecting anti-ram perimeter defense without making a visual feeling of a fortified bunker. Bollards are commonly used for traffic direction and control, and in purely decorative applications. However, bollards can serve many functions beyond security. They can be used purely artistic purposes, functioning as landscaping elements. Bollards can create visible boundaries of a property, or separate areas within sites. They can control traffic and they are often arranged to permit pedestrian access while preventing entry of vehicles.

Removable and retractable bollards can allow different levels of access restriction for a variety of circumstances. They frequently tell us where we could and cannot drive, park, bike, or walk, protect us from crime, shield vehicles and property from accidents, and add aesthetic features to our building exteriors and surrounding areas. Bollards can incorporate other functions like lighting, surveillance cameras, bicycle parking or even seating. Decorative bollards are made in a number of patterns to harmonize with a wide range of architectural styles. The prevalence of the very most common type of security bollard, the concrete-filled steel pipe, has encouraged the manufacturing of decorative bollards created to fit as covers over standard steel pipe sizes, adding pleasing form towards the required function.

Exactly What Is A Bollard?

A bollard is really a short vertical post. Early bollards were for mooring large ships at dock, plus they are still in use today. An average marine bollard is produced 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 term bollard also describes many different structures applied to streets, around buildings, as well as 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. If the supply of former cannons was used 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, along with outside supermarkets, restaurants, hotels, shops, government buildings and stadiums.

The most frequent kind of bollard is fixed. The easiest is an unaesthetic steel post, about 914 to 1219 mm (36 to 48 in.) above-grade. Specially manufactured bollards include not just simple posts, but also a multitude of decorative designs. Some feature square or rectangular cross-sections, but a majority of are cylindrical, sometimes using a domed, angled, or flat cap. They are offered in a number of metallic, painted, and durable powder coat finishes.

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 often needed, and therefore are designed so 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 count on their weight as opposed to structural anchoring to remain in place. They are designed to be moved rarely, then only with heavy machinery like a fork-lift.

Bollards generally fall under three kinds of applications:

Decorative Bollards – decorative bollards for architectural and landscaping highlights;

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

Security Bollards and Post Covers – decorative, impact-resistant bollard enhancements

Decorative Bollards

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

Decorative bollards are manufactured to harmonize with both traditional and contemporary architectural styles. The latter lean toward visual simplicity – often straight-sided posts with several reveals near the top. Styles created to match various historic periods normally have more elaborate shapes and surface details. Included in this are 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 feature a simple rounded or slanted top to discourage passersby from leaving trash or utilizing them for impromptu seating. On the other hand, they may be 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 often made from iron or aluminum casting. Aluminum bollards are desirable for applications where weight is a concern, for instance a removable bollard. Aluminum units tend to be a little more expensive than iron. For applications where 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 conventional foundry technique which is economical and well-fitted 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 which will machine 100% in the surface after casting to generate units with a uniform surface for optimum visual appeal.

Finish is a vital consideration in a decorative bollard, from functional in addition to aesthetic standpoints. Bollards are, by their nature, susceptible to being scratched or nicked by pedestrians and vehicles. Those located near roadways are in contact with 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 available on iron, aluminum, and steel – is definitely an especially durable kind of painted finish. The application process builds up a coating with very consistent coverage. During coating, any bare metal tends to attract the powder, eliminating pinholes in coverage. The baking method that completes the finish gives it additional toughness and abuse resistance.

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