Allowed slope on walkway ramp

I'm looking at getting a stairs made for an external access into an existing industrial plant.

I'm fairly constrained with clearances in all directions - between block walls, conveyor belts and fixed items on the ground but I'm happy I can get a width of 1,000mm between handrails, keep below 38 deg on the flight and stay within rise and going recommendations for semi-public stairways.

The stairs will take one flight onto a landing and then a short flight onto an existing landing on the side of the plant. The second flight is coming in at a fairly shallow slope of 22 deg and I'm wondering instead of stepping it, I could just lay something like GRP flooring along the length of the flight and make a ramped walkway of it. The length of the second flight is 3,500mm.

Does anyone know to hand if a ramped walkway at this slope would be allowed? Also, is it allowed to have a stairway and ramped walkway on the one rise of stairs?

You could start with reading TGD K. The latest edition can be downloaded here. You should also read BS 5395:3 which you will find here

Thanks @muffler

I have TGD K in front of me and surely enough, there's a small piece at the rear about ramps ... and a quick glance tells me I might be outside the slope allowed

I'll have a re-read of K and a read of BS 5395:3 in the morning
