The choice of mat depends largely on the size of the building, the number of people entering and the environment in which it will be placed. For example, is the outdoor environment prone to rain, snow or soil? This can be a problem in Northern Europe, while in southern Europe you may have a bigger problem with sand and gravel.
Then you should consider: how many people will enter the entrance on a daily basis? This has a tremendous effect on carpet selection. Safety and aesthetics also play an important role.
For a company, a good first impression is vital and the building manager will probably choose an expensive high strength mat that will remain in good condition even in the most adverse weather conditions.
