Are these mats strong enough to be used in a barn holding the weight of an 1800 lb dairy cow? We are searching for stall mats for our milking room in our barn.

Our 3/4" Extreme Mats were designed to be used as agriculture mats and have been used in horse stalls, milking rooms, and the like for years before they became popular in gyms, Cross Fit to be specific. So, yes, these rubber mats will be able to withstand the weight of a cow and are perfect for this use. They are very easy to clean and maintain and are very slip-reisistant, even more so when wet. They also are resistant to mold and mildew growth and are anti-fungal.
