They are a basic, practical, and cost-effective method of erecting anti-ram perimeter defense without making a visual feeling of a fortified bunker. Bollards are popular for traffic direction and control, and in purely decorative applications. However, bollards can serve many functions beyond security. They can be used for purely aesthetic 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.

Bollards can incorporate other functions like lighting, security cameras, bicycle parking as well as seating. Decorative bollards are created in a variety of patterns to harmonize with a wide range of architectural styles. The prevalence of the very most common form 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 for the required function.

What Is A Bollard?

A bollard is a short vertical post. Early bollards were for mooring large ships at dock, and they are generally still being used today. An average marine bollard is produced 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 word bollard also describes a variety of structures applied to streets, around buildings, as well as in landscaping. In accordance with legend, the very first street bollards were actually cannons – sometimes reported to be captured enemy weapons – planted in the earth as boundary posts and town markers. When the availability of former cannons was used up, similarly shaped iron castings were created to fulfill the same functions. Bollards have since become many varieties which are widely employed on roads, specifically in urban areas, as well as outside supermarkets, restaurants, hotels, shops, government buildings and stadiums.

The most typical 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 merely simple posts, but also numerous decorative designs. Some feature square or rectangular cross-sections, but most are cylindrical, sometimes using a domed, angled, or flat cap. They come in a selection of metallic, painted, and durable 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 frequently needed, and therefore are designed so the bollard can be simply collapsed to ground level and quickly re-erected. Both retractable units may 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 as opposed to structural anchoring in which to stay place. They are designed to be moved rarely, then just with heavy machinery such as 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 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 be an ornament. As standalone architectural or landscaping features, they can border, divide, or define a place. 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 second lean toward visual simplicity – often straight-sided posts with several reveals near the top. Styles created to match various historic periods will often have more elaborate shapes and surface details. These include 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 include a simple rounded or slanted top to discourage passersby from leaving trash or utilizing 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 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 slightly more expensive than iron. For applications in which a decorative bollard may be subject to destructive impact, ductile iron is really 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-suited to objects this size. However, sand-cast objects frequently bear surface irregularities that often leave the finished product less popular with the eye. 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 maximum 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 – which can be available on iron, aluminum, and steel – is surely an especially durable kind of painted finish. The application form process builds 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 made of aluminum can be a better option than iron. In the event the finish coat is damaged, aluminum oxidizes to some color which is generally more acceptable than the red rust created by iron. Aluminum and stainless are also offered in a variety of bare metal finishes. Functionality can be included in the otherwise decorative bollard. For instance, common option 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 in 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, including motion sensors or cameras.
