Concrete Lines have a huge selection of over 100 unique decks, including old school boards, longboards, cruiser boards, Pro models and decks from local Brisbane and Tweed artists, plus Australian brands. Concrete Lines have been in the business of skaters serving skaters since 2006. They�ve been in Tweed Heads, just south of the Queensland border promoting skateboarding, helping to get skateparks built, sponsoring local crew, doing some crazy downhill longboarding, and of course, selling some sick boards.
