Coir entrance mats use fibres taken from coconut husks. These fibres are cleaned, dried, and pressed into matting. The finished mat has a rough texture. This structure helps remove dirt and moisture from footwear. They are often used in doorways and porches. They are used inside buildings and under canopies. https://donovanzvpih.shotblogs.com/an-overview-of-coir-entrance-mats-53125219
