Span 220x45 C24

[Derbyboy]

What is the longest span on a ramp/gently sloping staircase?

I was thinking of using two parallel 45x220 C24 beams but am considering the longest span. The distance between the parallel beams will be somewhere around 100-120 cm. Snow zone 2.

I read different things in the available guides.

I don't understand the question? Are you referring to the vangern of a staircase?

Edit: I missed that it said ramp. Someone else will have to answer that. But spontaneously, I think you could aim for the calculations in the dimensioning table for heavy flooring. Somewhere in that region, I think it falls.
