The Q-Sign is the industry leader. The sign is extremely strong and durable. Manufactured from recycled Polypropylene, the sign has no metal parts. Although lightweight, the angled sign is designed to give a strong wind resistance.

Wind ResistanceAll temporary traffic signs must be able to withstand three different classes of wind speeds with the use of a ballast. The standard BS 8442:2015 states the three classes as the following:
Class A: 26.3 m/s (58mph)
Class B: 17.6 m/s (39mph)
Class C: 8.7m/s (19mph)
The Q-Sign was tested under strict conditions at the Full Scale Wind Tunnel at Mira to determine at which wind speeds the sign can withstand. Below are the results for the 600mm & 750mm Triangle and Circle Q-Sign. These results are a guide as to the recommended ballast weight for each Wind Class:
Withstood up to 26mph.
Recommended Ballast Weight: 0kg
Withstood up to 42mph.
Recommended Ballast Weight: 10kg
Withstood up to 59mph.
Recommended Ballast Weight: 30kg
