Where To Buy Bollards – Look At The Opinions..

The popularity of bollards has dramatically increased in the past decade because of heightened concerns about security. They are an easy, practical, and cost-effective method of erecting anti-ram perimeter defense without making a visual sense 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, working as landscaping elements. Bollards can create visible boundaries of the property, or separate areas within sites. They can control traffic and are often arranged to permit pedestrian access while keeping entry of vehicles.

Removable and retractable bollards can allow different amounts of access restriction for a number of circumstances. They frequently inform us where we can and cannot drive, park, bike, or walk, protect us from crime, shield vehicles and property from accidents, and add aesthetic features to the building exteriors and surrounding areas. Bollards can incorporate other functions such as lighting, surveillance cameras, bicycle parking or even seating. Decorative bollards are created in a selection of patterns to harmonize with an array of architectural styles. The prevalence of the very most common type of plastic safety bollards, 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 Is A Bollard?

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

Today, the phrase bollard also describes many different structures applied to streets, around buildings, and in landscaping. Based on legend, the very first street bollards were actually cannons – sometimes said 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 fulfill the same functions. Bollards have since evolved into many varieties that are widely employed on roads, particularly in urban areas, along with outside supermarkets, restaurants, hotels, shops, government buildings and stadiums.

The most common form 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 also a multitude of decorative designs. Some feature square or rectangular cross-sections, but many are cylindrical, sometimes having a domed, angled, or flat cap. They are available in a variety of metallic, painted, and durable powder coat finishes.

Removable bollards are used where the need to limit access or direct traffic changes occasionally. Both retractable and fold-down styles are employed where selective entry is frequently needed, and they are designed and so the bollard can be easily 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 depend on their weight instead of structural anchoring in which to stay place. They are designed to be moved rarely, and after that just with heavy machinery like a fork-lift.

Bollards generally belong to three kinds of applications:

Decorative Bollards – decorative bollards for architectural and landscaping highlights;

Traffic and Safety Bollards – bollards that offer asset and pedestrian safety, in addition to 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 are able to border, divide, or define a space. They can 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 second lean toward visual simplicity – often straight-sided posts with a number of reveals near 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 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 making use of 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 of iron or aluminum casting. Aluminum bollards are desirable for applications where weight is an issue, like a removable bollard. Aluminum units are generally slightly more expensive than iron. For applications when a decorative bollard might be subjected 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 often manufactured by sand-casting – a conventional foundry technique that is certainly economical and well-suitable for 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 that will machine 100% of the surface after casting to produce units using a uniform surface for optimum 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 relatively aggressive environment; petrochemical residues and splashes of diluted road de-icing salts may compromise zuhjvq painted finishes. Factory-applied powder coating – that is seen on iron, aluminum, and steel – is surely an especially durable kind of painted finish. The application form process increases 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 conclusion gives it additional toughness and abuse resistance.

In applications where greater physical abuse is predictable, decorative bollards made of aluminum may be a better choice than iron. If the finish coat is damaged, aluminum oxidizes to your color that is certainly generally more acceptable than the red rust produced by iron. Aluminum and stainless steel are also offered in a quantity of bare metal finishes. Functionality can be included in the otherwise decorative bollard. As an example, common option is the chain eye – linking 2 or more bollards with chain, making a simple traffic direction system. A sizable metal loop or arm on the side in the post allows parking and locking of bicycles, an increasingly popular choice as more people seek alternative green transportation. Bollards may also contain lighting units or security devices, like motion sensors or cameras.
