As we know, there are a few roof deck systems out now which have a 700mm cover.
Our PACE600 aluminium walkway system has always shown a maximum span of 670mm. However, what has not been made clear, is that for a continuous span (fixed to more than 3 battens) the span can be increased to 700mm.
So, when installing walkway on a roof deck with 700mm cover, the span can increase to 700mm.
