Security Bollards – See Us ASAP To Find Out Extra Specifics..

The prominence of bollards has dramatically increased during the past decade because of heightened concerns about security. They are an easy, 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 aesthetic purposes, working as landscaping elements. Bollards can create visible boundaries of the property, or separate areas within sites. They can control traffic and they are often arranged to allow pedestrian access while keeping entry of vehicles.

Removable and retractable bollards can allow different levels of access restriction for a variety 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 our own building exteriors and surrounding areas. Bollards can incorporate other functions such as lighting, security cameras, bicycle parking or even seating. Decorative bollards are produced in a number of patterns to harmonize with a variety of architectural styles. The prevalence of the very most common form of metal bollards for sale, 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 to the required function.

Exactly What Is A Bollard?

A bollard is actually a short vertical post. Early bollards were for mooring large ships at dock, and they are still used today. An average 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 applied to streets, around buildings, and in landscaping. Based on legend, the first street bollards were actually cannons – sometimes said to be captured enemy weapons – planted in the ground as boundary posts and town markers. When the supply of former cannons was applied up, similarly shaped iron castings were designed to match the same functions. Bollards have since evolved into many varieties which can be widely employed on roads, specifically 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 numerous decorative designs. Some feature square or rectangular cross-sections, but most are cylindrical, sometimes having a domed, angled, or flat cap. They are available in a selection 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 frequently 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 rely on their weight as opposed to structural anchoring to remain in place. They are designed to be moved rarely, then simply with heavy machinery such as a fork-lift.

Bollards generally belong to three varieties of applications:

Decorative Bollards – decorative bollards for architectural and/or landscaping highlights;

Traffic and Safety Bollards – bollards which provide asset and pedestrian safety, along with 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 an area. They may also 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 latter lean toward visual simplicity – often straight-sided posts with several reveals nearby the top. Styles created to match various historic periods normally have more elaborate shapes and surface details. These include 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 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, 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, for instance a removable bollard. Aluminum units tend to be slightly more expensive than iron. For applications where a decorative bollard may be subjected to destructive impact, ductile iron is really a safer choice than more brittle metals, as force will deform the metal as opposed to shatter and transforming it into possible hazardous flying projectiles.

Iron and aluminum bollards are usually manufactured by sand-casting – a conventional foundry technique that is certainly economical and well-suited to objects this size. However, sand-cast objects frequently bear surface irregularities that tend to leave the finished product less attractive to the eye. If high-finish consistency is desired, seek a manufacturer that will machine 100% from the surface after casting to generate units using a uniform surface for optimum visual appeal.

Finish is an important 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 subjected to a fairly aggressive environment; petrochemical residues and splashes of diluted road de-icing salts may compromise zuhjvq painted finishes. Factory-applied powder coating – which is available on iron, aluminum, and steel – is surely an especially durable form of painted finish. The applying 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 procedure that completes the conclusion gives it additional toughness and abuse resistance.

In applications where greater physical abuse is predictable, decorative bollards made from 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 can also be found in a number of bare metal finishes. Functionality may be included in the otherwise decorative bollard. For example, common choice 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 of 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, such as motion sensors or cameras.
