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 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://entrancemats80210.blogdiloz.com/38428898/understanding-coir-door-mats
