We shouldn't be using Steel Beams, when Alloy ones are available, which are easier to work with and just as strong, but you still see hundreds of jobs about, with Steel beams in them.
Scaffolding firms dont care what is easier or safer - or about our backs.
They only care that THEIR arse is covered and THEY earn as much money on a job as possible.
The HSE are using the Scaff-Step because of recommendations from the NASC (The very same firms, that we work for), without having any kind of feedback from the man on the street...
Their attitude is: 'Your going to use this Step and get used to using it - end of story.'
