Everything you need to know about getting a certified temporary fencing AS4687

2 MINUTE READ

There can be many components that make up your temporary fencing hire. Some parts are required and important components that form part of the standard install while other parts are additional components that help to enhance the look or security of the fence while they are erected on your site.

Read on for an overview of all the components available that make up temporary fencing.

Temporary Steel Fencing Panels

The temporary fencing panels are the most visible component of the fencing install. The panels come in several sizes and types but generally, you will find they are 1200mm or 2100mm high by 2500mm wide

We recommend a 2100mm high fence for around construction sites and 1200mm high panels for use during events and around pool constructions.

Standard temporary fencing panels are made up of a galvanised steel frame with a mesh infill.

Quality fence panels, such as the ones we use on all our installs, would have 40mm pipe diameter and are hand welded at every join for added durability.

Crowd Control Barriers

Another type of fencing panel is the crowd control barriers. These panels, are made of aluminium, are smaller in size, lighter in weight and consist of vertical bars rather than the square mesh infills.

Crowd control barriers are designed as more of a barrier to instruct the public on where they can and cannot go. The lightweight design of the panels does this while also making the panels easy to assemble, remove, stack and store.

It should also be pointed out here that when hiring your temporary fencing, it is possible to combine a mixture of panel sizes and types to achieve the best result for your site requirements.

Reg 126 Temporary Steel Fencing Feet

Fencing Feet

The foot of your temporary fencing hire is an important component for the overall security and stability of the install. The standard feet for temporary fencing is constructed of a plastic coated concrete. The weight of the concrete allows for stability, ensuring your fencing will not blow over in the slightest breeze.

The UV plastic coating is also important as it helps to maintain the longevity of the feet, protecting them from being degraded in the harsh Australian conditions.

The plastic coating also has two other benefits. It allows for the concrete to stand out by using highly visible colours (orange in our case), meaning it will less likely be a trip hazard and it prevents your site from being damaged by the raw concrete footing. This is particularly important if you have a finished floor, such as a tile or paver that you don’t want to be marked or damaged.

These concrete feet are often used when temporary fencing is being installed on construction sites and in public spaces and generally weigh around 25kgs.

Other feet available include steel plate fence feet. These are constructed of a flat steel plate with vertical bars welded to the base to allow the fencing panels to slip over the top and be secured in place.

Steel plate feet also designed to minimise the risk of a trip hazard and are mainly used on the shorter panels (temporary fencing around swimming pools for example).

Event fencing or crowd barriers work well with the steel plate feet as they are more streamlined, are easier to move and will not damage any existing finished surface.

The image above shows an analysis for the potential wind effects onto the braced panels. Stays, also known as wind braces, are an additional component to temporary fencing and are used as extra support. They are added to one side of the fence where the panels meet for increased strength and stability.

Stays help the panels to stay! They act as reinforcement particularly in high wind areas or where the temporary fencing install has a particularly long run and needs extra support.

Stays are also a good idea to be used if the temporary fencing install includes shade cloth, bunting or banner mesh advertising, as there is more chance of the panels becoming unstable during windy conditions.  In high wind prone areas, the use of shade cloth and printed banner mesh can create a “sail” type effect which can topple a fence with what might only be considered a mild breeze. The minimum standard according to AS-4687 is that a fencing installation must be able to withstand a windspeed of 54 km/hr.

To combat this, we have engineered different bracing solutions to suit multiple wind speeds, from servicing the minimum requirement of Stability Class fence at 54km/hr right up to 147km/h depending on your site’s specific requirements.

Clamps

Clamps are the components that tie your temporary fencing install together. They play an important role by keeping the panels erect secure and stable.

Each clamp consists of a pair of moulded metal pieces that are placed around the edge bars on the fencing panels and tightened securely by a nut and bolt in the centre.

Generally there is one set of clamps placed between each fencing panel towards the top, however, more clamps can be added for extra security and stability.

Clamps, just like the fencing panels are constructed of a quality galvanised steel.

Dog Bars

The 2100mm construction fence has a 150mm gap under the bottom bar, which can enable small dogs to squeeze under the fence. Dog bars are another additional component to add to your temporary fencing hire. Just like the name suggests, they are added to the bottom of the fencing panels to keep dogs in or out of your site.
