Coir mats are produced from natural coconut fibre. These fibres are cleaned, dried, and pressed into matting. The fibres create a stiff brushing action. The fibre texture scrapes mud and debris from shoes. Many homes and premises install them at access points. They are used inside buildings and under canopies. https://antislipmatting82501.blogchaat.com/39742339/understanding-coir-door-mats
