Corrugated Culvert Bunker Set — 6ft & 4ft Sections - 1/48

Corrugated metal culvert sections were a battlefield constant from the trenches of WWI through to the firebases of Vietnam — cheap, modular, and brutally effective as overhead cover.

This 1/48 set gives you four sections in two sizes to build everything from fighting positions and personnel bunkers to drainage infrastructure and logistics revetments.

Kit contains:
2 × 6-foot sections
2 × 4-foot sections

The 6-foot sections mirror real-world military-specification corrugated steel pipe (CSP), used by combat engineers for rapid-construction bunkers, command post shells, and blast-resistant sleeping quarters.

The 4-foot sections are perfect for drainage culverts, secondary entrances, tunnel approaches, or tight fighting positions. Mixed into a diorama, the two sizes create a natural sense of scale and improvised field construction.

Historically accurate corrugation profile and surface texture. Compatible with all major 1/35 Vietnam-era US and ARVN firebase dioramas, and equally at home in WWII Pacific, Korean War, or modern FOB builds.
