a slide Well for now lets just call it the straight escalator that doees not have stairs or the straight escalator

Marshall Steel Stairs are specialist in steel stairs. They are based in Leeds. You could go to their website and browse through their products or go straight to their showroom.

Try pouring some straight muriatic acid over them.

A "flight" of stairs may consist of differing numbers of steps. It depends on the architect, the engineer and/or the contractor and what there is to work with. We sometimes refer to a flight of stairs as the group of steps between two adjoining levels in a structure, but this is not set in stone. And a given flight of stairs between that pair of adjacent levels can be "broken" into two or more "sub-flights" depending on the area and geometry of the stairwell. There is probably a maximum number of stairs that will be set on a stringer, and a long, straight stringer may have a landing (one or more) to break it up for the benefit of the individuals who ascend or descend using this route. Consider the stairs on some of the ancient structures in South America. Hundreds of steps straight up with no breaks makes for a difficult climb, whether it be up or down.

You have to go in the castle, then you go straight, and turn right; and go up the spiral stairs, but if they're the long ones, you need to go to the other set of stairs closest to the big chair. Hope that helps. :)
