Coir entrance mats use fibres taken from coconut husks. The husks are processed to form a dense mat surface. The fibres create a stiff brushing action. 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://entrance-mat60368.like-blogs.com/39329026/an-overview-of-coir-entrance-mats
