Before you start building your fence you need to lay out the area properly to get a good idea for where the fence is going to sit in proportion to the house and surrounding area.It can be helpful to run string lines at the elevation that the fence will be at in terms of its finished height. You can run these string lines both at the top and at the bottom of the finished height of the fence wrought iron fences.
You will also want to spray paint the ground where the fence will be installed so that you can see where the post holes will need to be dug approximately. This can help you to determine any potential difficulties that you may encounter when actually installing the fence such as obstructions or grade issues with the property that you will need to account for in the design stage of your fence.
Setting the posts in place for your fence is one of the most critical components of the project. If the posts are not set correctly or are set out an angle or offset slightly the end results will be very noticeable in the Esthetic of the fence. Be sure to double and triple check your measurements before committing to digging your post holes. You need to be sure that you have even spacing of the post holes in that you have accounted properly for any intrusions such as the gate on the fence. Also you must consider the length of material that you’ll be using for the rails or stringers in the fence. The rails of the fence are the horizontal pieces that you attach the fence boards themselves to. If you put the post holes too far apart the stringers will not be long enough to reach from one post to the next. This is one of the most major problems that you certainly want to avoid when installing your own fence. The spacing for your fence posts should be equal so that is a quick and easy way to double check your spacing but nothing is a substitution for proper measurement with the correct tools.
When it comes time to dig the post holes you have a few different options. There are hand tools that can do the job however these require fairly extensive physical effort and should only be considered for smaller jobs. There are gas powered tools which can make quick work of even large jobs requiring many post holes to be drilled however this powerful machinery can be dangerous to use and has a bad reputation as being something that has the potential to cause injury.
It is regarded in the fencing industry that the diameter of the post hole itself should be 4 inches larger than the post. For example if you are setting 4 x 4 posts into place then you would want to drill and 8 inch diameter hole for the post hole.
The depth of the post hole is very significant as this will determine the overall strength and longevity of the fence. In the areas where the ground can freeze during the winter season. It will be extremely important to set the posts a minimum of 6 inches below the frost line. For all other applications. The post hole should be one third the height of the fence. For example a 6 foot fence should have a minimum of 2 foot deep post holes. If you were looking for an area that you can overbuild on this project. This is it. If you drill the holes and deeper than need be or use extra concrete. This amounts to extra cost and extra labor for your project but ultimately will result in a stronger, longer lasting fence.
