Tiles for hotels, shopping malls and airports must survive heavy, constant foot traffic and wheeled loads, stay safe when wet, and look uniform over a large area. Specify low water absorption, a high abrasion class, an appropriate slip rating and tight shade and calibre control.
These are commercial buyers who follow specifications closely. A weak submission loses the order before the tile is seen.
Which abrasion rating should you ask for?
For glazed tiles, the PEI rating measures surface abrasion resistance from class I to V. Heavy commercial areas such as lobbies and concourses normally call for class IV or V; see PEI rating for tiles. Unglazed and full-body porcelain is rated by a different abrasion test, since there is no glaze to wear through. Full-body tiles show wear less, because the colour runs through the thickness; full-body vitrified tiles explains the construction.
For the full list of properties, read floor tiles for commercial heavy traffic.
How should slip resistance be handled?
Entrances, washrooms, pool surrounds and spaces that are cleaned wet need a higher slip class than dry lobbies. The R scale, from R9 to R13, is used in many markets, and other markets rely on pendulum or dynamic coefficient of friction values. The right requirement is set by local regulation and the project specification, not by the tile supplier. See R11 and R12 slip rating for what the classes mean.
A very rough surface raises grip but is harder to clean. Balance both with the project team.
What else do project specifiers check?
Expect questions on the following:
- Water absorption, normally 0.5% or less for porcelain, with a test report from a recognised lab.
- Breaking strength and modulus of rupture for the thickness proposed.
- Stain and chemical resistance, since cleaning products in public buildings are strong.
- Size accuracy, with rectified edges for narrow grout joints on large formats.
- Shade range and the number of faces, so a large floor looks even.
Why do quantities and phases matter?
A hotel or mall needs thousands of square metres of one tile, often delivered in phases over months. The risk is a shade or calibre change between batches. Order enough from one production run if you can, record the batch numbers, and agree an overage for future repairs. One shade, one calibre per shipment explains how to control it.
What should you plan for maintenance and spares?
Public buildings need repairs without matching problems years later. Order a spare allowance from the same production run, label the boxes with the batch and shade, and store them on site. Agree with the factory how long it will keep the design in production. Ask for the manufacturer's cleaning guidance, because wrong cleaning agents and machines can damage polished and textured surfaces. A short maintenance sheet handed over with the project is a sign of a serious supplier and helps the facility team keep the floor in good condition.
