Weathered Cast Iron Rectangular Drain Grate

This 2K PBR texture set provides a realistic, weathered cast iron rectangular drain grate for urban and industrial site planning. This photogrammetry-based asset captures the rugged, worn aesthetic of a heavy-duty industrial drain grate. The surface exhibits characteristic oxidation, pitting, and natural debris accumulation, reflecting its typical service in an urban environment. The design features a robust, rectangular frame with parallel structural ribs and integrated cast lettering, providing high visual fidelity for close-up shots. The inclusion of displacement and normal maps ensures that the depth of the metal bars and the surrounding concrete interface is accurately represented, offering a convincing, tactile quality that stands up to detailed architectural rendering and site analysis.

The download is a 14.4 MB compressed archive with the texture set at 2K with colour, normal, roughness, metalness, ambient occlusion, displacement and opacity maps, ready for any metal/roughness PBR workflow in Blender, 3ds Max, SketchUp, Unreal Engine or D5.

Apply this PBR material to planar geometries in your rendering engine by utilising the provided albedo, displacement, normal, roughness, opacity, ambient occlusion, and metalness maps. The tileable nature of the texture allows for consistent mapping across large paved surfaces or streetscape models. For optimal results, ensure your displacement modifier is set to a reasonable subdivision level to capture the height information, and use the opacity map to correctly mask the voids between the metal ribs.
