Rusted Perforated Steel Beam — master file A sculpted perforated industrial beam sized for -scale dioramas, layout scrap piles, and factory interiors. The piece features evenly spaced round perforations along the flange and web, sculpted pitting and flaking to suggest long-term corrosion, and slightly deformed ends to read as salvaged or cut sections. The perforations are sized to remain readable on common hobby printers when printed at while giving attractive negative space for weathering and shading. Included: one master digital file with conversion guidance to scale the piece for other hobby scales. The beam is intended as a ready scenic element: lay single lengths across broken roof trusses, stack multiple pieces for a salvage heap, or use short sections as barricades and cover for tabletop scenarios. For finishing, apply a dark wash into pitting and perforations, layer rust tones with pigments, then lightly abrade edges to simulate exposed metal. The sculpt accepts common weathering techniques and is sized to integrate cleanly with rolling stock and structures.
