Can these mats be used in a walk-in freezer? They would have four-leg shelving units on them with heavy frozen food items.

Our Extreme Mats can be used as flooring in a walk-in freezer. These mats are very durable and will be able to withstand the weight of heavy shelving units. Since these mats are made from rubber, they are very slip resistant even when wet and are very easy to clean and maintain. They are also mold and mildew resistant and can be sealed to create a non-porous surface that can be easily sanitized.
