Frequently Asked Questions
Are they solid or hollow?
EnduraPost Square Pickets and Droppers and PLUSpost's are solid recycled PP (polypropylene) plastic.
Do they break easily?
Whilst it is possible to break them, it is not easy to do so when installing correctly. They are made to be installed the same way as timber or steel pickets are. Drive them in the ground using either manual, petrol, pneumatic or hydraulic impact drivers. Avoid using heavy duty pole driving drop hammers or sledgehammers. Download the install guide for more details and if they are breaking, please contact EnduraPost.
Do they burn easily in a bushfire?
They have been tested to withstand fire up to 350⁰C which is usually hotter than a grass fire that normally reaches between 200-250⁰C. Some larger bush fires can burn hotter particularly if the fuel load is wood. Keeping wood away from fence lines should provide adequate protections, meaning that if a fire happens to pass through it is likely going to be a grass only fire. They are also NOT susceptible to ember attacks unlike wood.
Will they last against the hot sun in Australia?
They have been treated with a UV treatment to last 50+ years
Will they bend over in the hot sun?
Although they are made of plastic, they are not going to bend over in the hot sun. Plastic can change shape when there are temperature differences from one side to the other. If pickets are laid down on the ground in direct sunlight, they may start to warp or bend but that is because the polymers move due to temperature variations from one side to the other. If this occurs, you can turn them over and they will straighten once again. This does not impact the strength or durability of the picket, and once they have been driven into place the temperature variations are not severe enough for them to warp or bend.
How do I run barbed wire through the holes?
Although the photos show plain wire run through the holes, many prefer to use the holes to tie back to instead. Both methods work well for plain wire, whereas, for barbed wire or hinge-joint / ring-lock simply tie back to the appropriate holes provided. You may want to use the award winning Davo's clip to easily attach any kind of wire.
Can I drive them in with a petrol driver?
Yes, they are tough and can be driven using mechanical or motorized drivers, or, by hydraulic drivers.
Can I build my entire fence with the EnduraPost Square Pickets?
As they are made from plastic, we only recommend they are used as an in-line picket. They are not suitable as a weight bearing post like a strainer or in-line stiff post. It’s recommended that EnduraPost Square Pickets be combined with End Strainers or similar. Then we recommend that a stiff line post or similar is installed as support after every 6 to 10 EnduraPost Square Pickets in a straight line, or, when the fence should make a turn.
Are they harder to drive in than a steel picket?
They are slightly harder to drive in due to the surface area difference compared to steel pickets.
How should I drive them into stony or tough ground?
For stony or very hard ground we recommend helping them by predrilling a pilot hole using a 24-35mm x 450mm earth auger or masonry drill before driving them in.
Do they loosen in the ground?
Due to their unique design allowing them to have some flex with strong memory bounce back, they do not typically loosen in the ground. For this reason they also do not need to be inserted into the ground as deeply, we recommend a min 300mm is sufficient for most applications in most soil types.
