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 fibre texture scrapes mud and debris from shoes. They are often used in doorways and porches. They perform well in covered external spaces. https://entrancemats39146.fireblogz.com/71051663/an-overview-of-coir-entrance-mats
