Coir entrance mats use fibres taken from coconut husks. The husks are processed to form a dense mat surface. The finished mat has a rough texture. This structure helps remove dirt and moisture from footwear. Coir mats are commonly placed at entrances. They are used inside buildings and under canopies. https://coir-entrance-matting57764.blogoscience.com/46223483/an-overview-of-coir-entrance-mats
