Coir entrance mats use fibres taken from coconut husks. The raw material is treated and shaped into firm matting. The finished mat has a rough texture. The fibre texture scrapes mud and debris from shoes. Coir mats are commonly placed at entrances. They are used inside buildings and under canopies. https://natural-coir-entrance-mat39009.loginblogin.com/47891701/understanding-coir-door-mats
