How quickly do rapid roller doors open and close?

While rapid doors can open and close at 2 to 2.5 metres per second,their speed is largely influenced by the opeining size and the environment(whether external or internal)in which it's installed.

For example,a smaller internal door that deals only with low air pressure can have fibreglass(GRP) battens and will open quickly.On the other hand,a larger external door exposed to wind will need to be more robust(with more mass),and therefore will need to run a little more slowly.
