What types of messaging do facilities include on custom mats?

The most common type of messaging we’ve seen is brand/logo or sometimes just design elements that match the aesthetic of the facility. Sometimes caution markings are used for safety reasons. There are also some interesting carpet patterns or textures that can be used on mats that make for interesting and aesthetically pleasing flourishes in the facility.

Facilities usually include a standard company logo on custom mats. In large downtown markets like Chicago and New York City, it is also very common to include the street number and building name.

Mainly, personal branding and safety notifications. Logo mats reinforce your company message and safety mats are great reminders of what hazards to be aware of around your workplace.

Messaging most often includes a logo, company name, building name or street address.

Logo matting is very popular in many commercial settings, including banks, health care settings and anywhere else where the business has a need to keep the floor both clean and safe. Entrance mats designed with the businesses’ logo are very popular, as are mats specifically designed to help employees avoid fatigue when their jobs require standing for long periods of time. Employees appreciate custom matting in copy rooms, break rooms and in individual workstations, and these types of placements offer a unique opportunity to provide a customized message, such as a safety reminder or a “customers first” pledge.

A large portion of the artwork used for custom logo mats is simply the customer’s logo and some add a tag line if applicable. Safety and public service messages are a popular choice as well.
  — Mark Roberts, National Accounts Specialist, The Andersen Company

Mostly this is about branding and first impression.  Generally is either a company logo or simply a design that improves the appearance of the entry and coordinates with other design elements in the lobby.
