A wooden arch does not require too many skills to be built and when it is built in the treated lumber, it is going to make a lasting impression. The arch can be rounded, pergola like, flat or pitched. The procedure on how to make a wedding arch out of wood is still the same, you only need to mark a place, to assemble the wood and to erect the beams and posts. You can then place the rafters at a top. It is advised to use a treated lumber, rustproof screws and metal shoes for the posts, if you want the arch to last long. However, if you want a just one time arch, you can use any wood. You have to ensure always the safety of the people around you.
