Looks good to me. I like how you put the Facebook ‘LIKE’ button at the bottom of every page so if someone really likes it, then they can easily share it with their friends. It is a clean design and easy to follow and understand.
One thing you might want to consider, you might want to change your Permalinks. There is nothing wrong with what you have now, but if you try to refer people to a certain page of your site, it would be a lot easier to give them a cleaner address like ‘https://metalprovider.net/contact’ rather than ‘https://metalprovider.net/?page_id=23’. If you do want to change it, just put in ‘/%postname%/’ in the Custom Structure field and your done. Like I said just a suggestion. Good Luck.
