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://natural-coir-entrance-mat70098.anchor-blog.com/19596460/an-overview-of-coir-entrance-mats
