Can your WPC products be used in salty environments, for example near the ocean?

November 30, 2021

Yes, Salt does not damage COOWIN composite decking under normal circumstances. In fact, we suggest our customers use rock salt to melt ice on the decking. The salt has little drying effect on the decking. This makes composite decking especially convenient if you live near saltwater. While composite decking is susceptible to abrasive substances, salt, which can often serve as a scouring powder, is not coarse enough to damage composite decking. Regardless, don’t rub or press salt into composite decking.
