Coir entrance mats use fibres taken from coconut husks. The raw material is treated and shaped into firm matting. The fibres create a stiff brushing action. This structure helps remove dirt and moisture from footwear. Coir mats are commonly placed at entrances. They are used inside buildings and under canopies. https://antislipmats01097.blogrelation.com/45998617/understanding-coir-door-mats
