Posted By Bob Youel manufacturers do not like their systems being mixed with other manufacturers stuff Even where differing systems are supplied by the same manufacture mixing is still not [usually] the way to go Ask the supplier etc

Posted By david sheehan Hi Paul, I was on a Bovis site recently and noticed the same thing.I spoke to the scaffolder and he said that they use the different stairs on the same system to achieve the correct angles as the scaffold was being used by brickies who need half lifts on some levels to lay their block. The mix and match question will probably only come into dispute if a failure of any sections occured and the individual manufactures looked liable.
