Hi I'm writing this because I'd really like to see inclined steel railing with classical stairs too, is this possible? I'll wait for a reply! ^^
Also thank you in advance!

Salute, this is unfortunately not possible I'm afraid because the tailings on the metal stairs of the mod are actually part of the stairs block itself, and I tell the stairs to show the railings when clicked with one.
For adding railings to any stairs, the way how Chisels & Bits works would have to be implemented, that is too big for Engineer's Decor. Sorry :/

Oh don't worry! It's not an important thing to me, just an idea ^^
