3ds Max Industrial Steel Exterior Stairs
A multi-flight external steel staircase bolted to a building: painted box-section stringers, open grating treads, tube-and-bar guardrails and intermediate landings wrapping a central column, read as a fire-escape or plant-access route. Modeled in 3ds Max (.max) with V-Ray shading, it suits exterior visualizations of factories, warehouses, car parks and commercial blocks that need a code-style egress stair.
