This Galvanised low cost Fold Down Hinged Residential Bollard is designed to restrict access to car parking spaces, driveways etc, and acts as a visual deterrent.
SPEC: 63.5mm diameter x 620mm o/height.
GROUND CLEARANCE: 102mm.
Padlock and Fixings Bolts are included in the price.
The floor mounted base is secured using 4 No. M10 Anchor Bolts to a prepared concrete foundation. It is lockable in the upright position by means of a padlock.
Should you require this post to be set in either Tarmac or Block Paving, then the M10 Anchor Bolts will be unsuitable, has any would be thief can quite easily remove the post by pulling from these types of surface and taking away with the post part of the groundwork.
We do offer a solution to this, it is called a Build in Base and this just needs to be concreted into the ground, thus preventing the removal of the post and groundwork.
This post is now FULLY manufactured within the United Kingdom, and the base is manufactured from Mild Steel, therefore making this more sturdy, also 4 No. M10 Through bolts are now required instead of 3,making this more secure when fitted on the ground.
A drop down or fold down driveway security post uses a padlock to secure it in place and give security when upright. They can be padlocked in the down position when not in us to stop theft of the post. There are variations with different makes and models of drop-down security posts.Some can be hinged and are not removable.
These kinds of security post must be manually dropped down on the driveway when access is needed in and out the driveway with a vehicle.
They should always be fitted to your own private driveway and never fitted to a public highway, pavement, or road.
The drop hinged or fold down security post are fixed to the ground by bolts screwed into the paving surface or by fixing abase with concrete within the driveway for the post to fit into.
Fold down, hinged, or drop-down driveway posts are usually the cheapest security posts for driveways you can have fitted. They give good security against being rammed with another vehicle. There is also a good selection to choose from. Although they are not as strong as a pull up telescopic post.
SPEC: POST - 63.5mm diameter x 620mm o/height.
BASE -Mild Steel as opposed to Aluminium, as these can easily be damaged.
FINISH: POST - Galvanised
BASE - Powder coated Black
GROUND CLEARANCE: 102mm.
Size of the hole on the base for the padlock to go through is 12mm.
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.
