Metal Deck Floor Plate

A 4 x 4 m floor module that lands on the steel frame bay's top flange at 3 m: profiled galvanised steel decking with 60 mm trapezoidal ribs running one way, an edge trim and a closure strip, shear studs welded through at 300 mm and a side lap.

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
