Coir entrance mats use fibres taken from coconut husks. The raw material is treated and shaped into firm matting. The finished mat has a rough texture. 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://coir-matting74847.blogdemls.com/39519147/an-overview-of-coir-entrance-mats
