BLUE RIBBON > POSTS AND POLES BLUE RIBBON™ Posts and Poles are the environmentally sound choice for agriculture. They have a life cycle that starts green, stays green and remains green for years to come. We start green by using wood, the world's only renewable building material. All Blue Ribbon wood products come from sustainably managed forests. We stay green by pressure-treating with environmentally friendly AQUA SEAL® waterborne preservatives. Blue Ribbon wood products pressure-treated with AQUA SEAL have been EPA approved for use in agriculture. We remain green by producing pressure-treated wood products that last substantially longer than untreated wood products. Treated Blue Ribbon wood products have the longest service life in agriculture. When you specify Blue Ribbon posts and poles, fewer trees are used, and you help conserve our forests.
