Natural coir mats are made using coarse coconut fibres. The raw material is treated and shaped into firm matting. The fibres create a stiff brushing action. The design supports effective dirt control at the door. Coir mats are commonly placed at entrances. They are used inside buildings and under canopies. https://emilianoedaoy.blog2news.com/40013072/an-overview-of-coir-entrance-mats
