U-DEK marine decking is owned, manufactured and distributed around the world by Ultralon International Foams. 

Over the past forty years, Ultralon has established itself as a niche manufacturer of high quality closed-cell cross-linked foams, with a very tight consistent cell structure. As a result, Ultralon has focused on market sectors where foam performance is key, and includes supply to the world’s top 12 ski and snow board boot manufacturers and to various companies making protective head gear for rugby union and rugby league head gear. The company also supplies PE and EVA foam to the orthotic, construction and packaging sectors around the world. U-DEK is the company’s marine brand which is focused on the production and supply of foam for marine decking in the USA, APAC and EU regions.
