Fencing : Getting it Straight.

We realise that many properties are not perfectly level, often on a steep or undulating slope.  When ordering your fence you can provide us with the gradient, or step down.  Our fabrication team can then customise your panel to suit your individual situation.  This will ensure no time wasting with less time cutting and fabricating on site.  We will take the guesswork out of building your fence.  Saving you time and money.

Our picket fence panels are made in standard lengths of 2340mm or 2400mm depending on the style.  When you order your fence we will round up the number of panels supplied, so that you will never run short on site. Therefore, if during installation you find that a planned post is situated above a service such as a water main or power cable, you can cut one of the panels short to avoid the service.

And that is our unique way of Thinking about solving any contingencies before they arise.

In fact, that is Think Fencing , straight talk!


You are reading this for one of two reasons, reason one is you have just purchased a beautiful new fence and are excited to work out how to put it together correctly.  Or you are considering a new Think Fencing fence and want to see how it goes together.

Like building anything careful planning and preparation is the key to a quality job.


If you need to remove an old fence or clean up the area, do this before you start marking out your new fence.


When you fence arrives you will have a pack of posts, rails, pickets, caps, Gates and other hardware.

It is important to lay all of your components and position them in roughly the correct spot along the fence line.  By doing this you can visually identify where everything goes.


You can see how the posts have slots to slide the rails into.  Before you slot the rails into the posts you must crimp the ends of the rails with the crimper supplied.  4 crimps per rail (2 crimps per end).  The crimps lock the rails into the posts.


All Think Fencing rails are supplied in either 2340mm or 2400mm.  We always round up with our panels making sure you always have extra length.  This gives you the flexibility to cut the rails to size in between your posts.

This is important if you find yourself with a planned post position right above a service such as a water main.  You can cut the rails and move the post position to make this panel shorter and avoid the obstacle.

You also have the flexibility to adjust the panels so that they are all the same length, ie an even post spacing across your fencing run.  Rather than a short panel at one end.


Now you have worked out where your fence is going to go and how it’s going to fit together you can start to mark out where you holes are going to be.

Always work on center of post measurement.

Helpful hint:  After you have calculated the center of post spacing simply cut a piece of plastic or timber 127mm shorter than the calculated length and that spacer should fit perfectly in between your posts.

If you have a gate opening of 1200mm you will need to set the posts 1327mm center to center.  And the gate required to fit this 1200mm opening will be less 25mm for the hinge and 30mm for the latch.  So overall gate size will be 1145mm for a 1200mm opening.


Using an auger or shovel you need to dig the hole at least 300mm wide and 650mm deep.  The post will only sit 600mm into the hole with a 50mm solid foundation of concrete below.

Note: 25Mpa concrete recommended.

In soft sandy areas it may be necessary to dig the hole deeper to achieve a solid footing for your post. You must always have at least 500mm of the post set into the concrete footing to ensure the post will not move in the footing.


Gate installation

When you provide us with the measurements of your fence and if you are ordering a gate we need to know the gate opening. This is so we can manufacture the gate correctly, taking into consideration a gap for the hinges and latch. When installing a gate there are 4 simple steps that if done accurately will result in a perfect gate installation every time.


Mark out your posts to the correct spacing.  So if you have a 1200mm opening it is critical to measure the distance in between the posts to be exactly 1200mm.   Dig the holes


If you have the fence attaching to a gate post you must seal the end of the rails going into the post.  Meaning stuff the end of the rails with paper, foam or simply use sticky tape.  (this prevents concrete from flowing into the rails.   Insert the rails into the post


Mark out your posts to the correct spacing.  So if you have a 1200mm opening it is critical to measure the distance in between the posts to be exactly 1200mm.   Dig the holes


Using 2 x 12mm Steel REO bar, drive the bars into the ground 100mm below, and level with the top.  Set the bars so that they are both spaced evenly apart. (not running along the side of the post) and fill the post with concrete.

Let the concrete set overnight if possible then fit the gate.  If you are not able to allow the concrete to set overnight you can prop the gate up so it is not bearing weight on the post.  Allow the concrete to set hard before you put any weight on the post.
