The prominence of bollards has dramatically increased during the past decade due to heightened concerns about security. They may be a basic, practical, and cost-effective way of erecting anti-ram perimeter defense without making a visual sense of a fortified bunker. Bollards are widely 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 amounts of access restriction for many different circumstances. They frequently tell us where we are able to 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 perhaps seating. Decorative bollards are made in a number of patterns to harmonize with a wide range of architectural styles. The prevalence of the most common form of security bollard, the concrete-filled steel pipe, has encouraged the manufacturing of decorative bollards made to fit as covers over standard steel pipe sizes, adding pleasing form for the required function.

What Exactly 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 normal marine bollard is manufactured in cast iron or steel and shaped somewhat such as a mushroom; the enlarged top is made to prevent mooring ropes from slipping off.

Today, the term bollard also describes a number of structures utilized on streets, around buildings, as well as in landscaping. Based on legend, the initial street bollards were actually cannons – sometimes said to be captured enemy weapons – planted in the earth as boundary posts and town markers. Once the flow of former cannons was utilized up, similarly shaped iron castings were created to fulfill the same functions. Bollards have since evolved into many varieties which can be widely employed on roads, specifically in urban areas, as well as outside supermarkets, restaurants, hotels, shops, government buildings and stadiums.

The most common type of bollard is fixed. The simplest is definitely an unaesthetic steel post, about 914 to 1219 mm (36 to 48 in.) above-grade. Specially manufactured bollards include not just simple posts, but in addition a wide variety of decorative designs. Some feature square or rectangular cross-sections, but a majority of are cylindrical, sometimes with a domed, angled, or flat cap. They are offered in a number of metallic, painted, and sturdy powder coat finishes.

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

Bollards generally belong to three varieties of applications:

Decorative Bollards – decorative bollards for architectural or landscaping highlights;

Traffic and Safety Bollards – bollards that provide 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 could border, divide, or define an area. They can 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 second lean toward visual simplicity – often straight-sided posts with several reveals close to the top. Styles designed to match various historic periods normally have more elaborate shapes and surface details. Such as 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 deter 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 frequently made of iron or aluminum casting. Aluminum bollards are desirable for applications where weight is a problem, for instance a removable bollard. Aluminum units are generally a little more expensive than iron. For applications in which a decorative bollard might be susceptible 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 that is economical and well-suited to objects this size. However, sand-cast objects frequently bear surface irregularities that often leave the finished product less attractive to the attention. If high-finish consistency is desired, seek a manufacturer which will machine 100% in the surface after casting to produce units with a uniform surface for max appearance.

Finish is a crucial 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 subjected to a fairly aggressive environment; petrochemical residues and splashes of diluted road de-icing salts may compromise wygcgg painted finishes. Factory-applied powder coating – that is seen on iron, aluminum, and steel – is an especially durable type of painted finish. The application 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 manufactured from aluminum might be a better option than iron. When the finish coat is damaged, aluminum oxidizes to your color that is generally more acceptable compared to the red rust made by iron. Aluminum and stainless are also offered in a variety of bare metal finishes. Functionality could be included in the otherwise decorative bollard. As an example, common choice is the chain eye – linking 2 or more bollards with chain, making a simple traffic direction system. A big metal loop or arm on the side of 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, like motion sensors or cameras.
