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. The fibre texture scrapes mud and debris from shoes. They are often used in doorways and porches. They are used inside buildings and under canopies. https://coirentrancemats35431.elbloglibre.com/39823522/understanding-coir-door-mats
