Coir entrance mats use fibres taken from coconut husks. These fibres are cleaned, dried, and pressed into 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://coir-matting27269.educationalimpactblog.com/61111306/what-are-coir-mats
