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. 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://rylanhhgbv.oblogation.com/38464931/what-are-coir-mats
