Coir entrance mats use fibres taken from coconut husks. 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. They are often used in doorways and porches. They perform well in covered external spaces. https://coirentrancemats47887.blogspothub.com/38314330/an-overview-of-coir-entrance-mats
