There is one other option for mezzanine floors which is preferred in many applications because of the insurance benefits. Welded grating, is a common choice in the waste management, mining, and food service industries. Steel grating allows for air, light, heat, and fluids to pass through the deck surface. It is strong, durable and virtually maintenance free. Welded grating is a system of interlocking, perpendicular bars; it provides a smooth clean look and excellent lateral support. Steel grating can be an economical choice due to the fact that in many cases, insurance companies will only require sprinkler systems above the mezzanine, since the open grating allows the water to reach lower levels.

The most durable type of mezzanine flooring by far is concrete. With a high point load and minimal transmission of noise through the deck, concrete should be used in high capacity industrial and military applications where the mezzanine is considered to be permanent. Steel decking is provided with pour stop needed to pour up to a 6-inch concrete floor.
