One of the most common options for decking a mezzanine is to use corrugated steel decking material covered by a layer of Advantech. Advantech is a high-quality product superior to ordinary plywood and OSB options due to its enhanced strength, stiffness, and moisture resistance. Its advanced density provides a solid and secure resistance to foot traffic and is designed to withstand weather conditions better than ordinary plywood. This decking method is considered to be our most economical selection and materials are readily available.
