what is a bulkhead is a strong wall used in the transportation and automotive sectors to divide the cargo compartment of trucks, vans, and trailers from the driver's cabin. In addition to increasing temperature management in refrigerated vehicles and boosting noise insulation, this separation also increases safety by keeping changing cargo out of the driver's compartment. To withstand the shock of moving cargo, trucks' bulkheads are frequently constructed from reinforced materials like steel, aluminum, or composite panels. Bulkheads are used in passenger cars as well as specialized transport vehicles like police vans and ambulances, where they offer safe compartments or help shield passengers from potentially dangerous substances.
