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 fibre texture scrapes mud and debris from shoes. They are often used in doorways and porches. They perform well in covered external spaces. https://codyywpvo.nizarblog.com/40037265/an-overview-of-coir-entrance-mats
