It almost goes without saying Crash rated gates are heavy and solid !

The one shown in the photo is no exception, this gate would weigh in at around 2 ton, there was a requirement for relatively fast opening and reliable operation.

Even though this is a crash rated gate made in the UK, the gate is used extensively during the day for a new car storage yard, so the requirement was to have a 100 % duty cycle and open at around 600mm/sec, this model GDS 630 Li CH does exactly that !
