Natural coir mats are made using coarse coconut fibres. These fibres are cleaned, dried, and pressed into matting. The fibres create a stiff brushing action. The design supports effective dirt control at the door. They are often used in doorways and porches. They are used inside buildings and under canopies. https://emiliojjbql.pages10.com/an-overview-of-coir-entrance-mats-74959299
