The first picture is the old deck.
We removed the decking and enlarged the size of the main deck. The decking is ironwood that comes from South America. The rails are iron pipe 2″ top rails and 1″ lower rails that can be painted or copper cladded.
When using cedar decking the cedar looks dirty and unfinished, even though you stain and treat it. You don’t want to use treated lumber for decking or rails because the wood is treated with copper arsenic, that will pass through the skin into your body. I’ve built decks out of Trex decking, but the decking is unstable, in some cases it has expanded so much that the deck looks like a lake when it rains. Also trex molds you have to clean it yearly, but you can not use a power washer. So I’ve switched to Ironwood for decking with great results.
