This is the strongest wood decking on the market. Meet Ipe. Imported from Brazil, Ipe can last 50-75 years even when exposed to the sun. Ipe is so dense, it sinks in water. Overseas Hardwoods Company (OHC) Ipe has been famously used in roller coasters, The Houston Zoo, Ponce City Market, and Suntrust Park. For projects built to outlast you, choose Ipe.
