External Staircase

Bolt-on exterior steel staircase for a facade, a single straight 3 m floor-pitch flight 0.9 m wide with open treads, a slim tube handrail and a small top landing that meets a doorway.

风格：low-poly, flat-shaded vertex colors, no textures, single shared material, so any set of these merges to one draw call; shares palette and scale with its kit
