- Dig holes where you will erect your posts. Make sure to dig deep enough so that the posts can go down 18 inches.
- Erect the 5 x 6 inches posts, setting them at 6 1/2 feet intervals.
- Erect the intermediate posts (3 1/2 inch square) for added strength.
- Pour concrete into the holes where the base of the posts are erected. This will strengthen and stabilize the posts.
- Screw or nail the planks into position. Place them in three rows in each section. Use galvanized screws or nails to ensure that they are rust proof.
- Use a spirit-level to make sure that the planks are horizontal.
- Connect or butt-join the planks at the center of a post. Try to stagger each plank on each row to make sure they are more stable.
- Fit a post cap on each post to give a finished over-all appearance. This can also help protect the posts.
