Coir mats are produced from natural coconut fibre. 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. They are often used in doorways and porches. They are used inside buildings and under canopies. https://troybpbkv.bleepblogs.com/39810643/what-are-coir-mats
