The main difference between 3G and 4G pitches is that 3G pitches have infill, while 4G pitches do not:
Infill: 3G pitches contain sand and rubber infill, while 4G pitches do not.
Safety: 3G pitches are considered safer and more comfortable than 4G pitches because of the infill.
Maintenance: 4G pitches are lower maintenance than 3G pitches.
FIFA approval: 3G pitches are the only artificial turf technology approved by FIFA and other football governing bodies. 4G pitches are still in the early stages of development and have not been accredited by any major sporting body.
Usage: 3G pitches are suitable for many different types of sports, including football and rugby. 4G pitches are typically an option for indoor areas and limited access areas.
Cost: 3G pitches are cheaper than 4G pitches.
Other differences between 3G and 4G pitches include:
Pile height: 3G pitches have a longer pile height, usually between 40-60mm.
Weatherproof: 3G pitches are weatherproof and free-draining.
Wear and tear: 3G pitches can withstand intensive usage without showing signs of wear and tear.
