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://anti-slip-matting95261.wizzardsblog.com/39771168/an-overview-of-coir-entrance-mats
