UNIQUE SELLING POINT WITH THIS PRODUCT IS THAT IF THE INNER GETS DAMAGED THEN ONLY THIS NEEDS TO BE REPLACED YOU DO NOT NEED TO EXCAVATE THE COMPLETE UNIT
Where a physical presence to protect from ramming, this Anti Ram Raid Bollard ideally suits. It is specially designed to withstand significant force, they protect buildings from deliberate vehicle collisions.
This extremely strong ram raid telescopic post is a proven deterrent against vehicle theft and ram attack, and are very effective in protecting banks, jewellers, warehouses, shops, stores, and property against ram raiders. It has been approved by both Police and Local Government Authorities and recommended by insurance companies.
Anti-Ram Raid Bollards provide an excellent means of preventing attacks from vehicles crossing boundaries. It is particularly important where large amounts of cash are being held near an entrance, also store fronts which are mostly built of glass to make their interior more attractive to customers. This also means that most shops tend to have their tills near the entrance, which also makes the area prone to attacks.
Not only will they enhance the security of a building but will also reduce the risk of damage. They will also act as a strong visible deterrent.
Manually retractable bollards (lowered by a key mechanism) are found useful in some cases since they do not require retro fitting into existing landscapes, or any electrical hook ups or hydraulic systems
The unit is secured by a padlock (not supplied)situated inside the flanges to make it difficult for access.
Raising and lowering can be achieved by using a "T Key”. Once the post is lowered it should lie flush with the ground surface.
The inner of the post can be removed and replaced when damaged or needs servicing (reducing the time needed to excavate).
Replacement inners are available under our Accessories heading.
The post is manufactured from mild steel and is galvanised to offer a level of protection against corrosion.
The photographs shown of the padlocks (not supplied by us) are a Shutter Padlock and Discus Padlock, both of which have been recommended by customers both old and new.
SPEC:
HEIGHT ABOVE GROUND: 720mm (open)
LENGTH OF UNIT O/A: 950mm (closed)
FINISH: Hot dipped galvanised

We recommend that these posts should be positioned no more than 1.2M – 1.3M apart to prevent vehicle access.
Additional T Keys are available under our Accessories head
The Security Screws used are shown in a separate photograph.
Galvanising
The basic specification for hot dip galvanized coatings on iron and steel articles is defined by a single standard, EN ISO 1461 ‘Hot dip galvanized coatings on iron and steel articles – specifications and test methods’. However, there are some exceptions to this standard (see thicker coatings below).
BS 729 was the old British galvanizing standard for hot dip galvanizing. It is now superseded by (BS) EN ISO 1461.
When hot dip galvanizing is specified, the surface of the steel is completely covered with a uniform coating whose thickness is determined principally by the thickness of the steel being galvanized (see Graph 1 below).
This is an important advantage of the galvanizing process; a standard coating thickness is applied almost automatically. The actual thickness of galvanized coating achieved varies with steel section size, surface profile and surface composition. Actual coating weights are often much more than the minimum specified in the standard. As coating life expectancy figures quoted are based on the minimum coating thickness, they are therefore usually very conservative.

Guidance on the design and performance of hot dip galvanizing is contained in EN ISO 14713 Part 1 and 2.
EN ISO 1461: coating minimum masses/ thickness on articles that are not centrifuged.
EN ISO 1461:coating minimum masses/thickness on articles that are centrifuged.
Thicker coatings than those set out in EN ISO 1461 can give additional protection for use in particularly aggressive environments and can be specified in conjunction with EN ISO 1461. It should, however, be emphasised that for most applications, thicker coatings are rarely necessary.
Grit blasting prior to galvanizing is usually the most appropriate method and a requirement for a nominal coating thickness of 1000 g/m² (140 µm) has been successfully specified for steel of 6 mm section thickness. For structural steelwork, it is advisable to ascertain whether thicker coatings could be achieved through their greater section thickness and without grit blasting.
Achieving thicker coatings through specification of a reactive steel is normally only appropriate for specific applications.
