Duty Bulkhead
What’s a Duty Bulkhead?
A Heavy Duty Bulkhead is an 11-gauge solid steel panel welded to the truck body for structural integrity.
What It Does:
- Strengthens the truck for heavy-duty operations
- Protects the cab from shifting loads in the bed
- Ensures durability in rugged highway environments
- Welded directly to the truck body.
- Provides a stable base for mounted equipment
- Built to withstand harsh conditions.
Available Types:
- Standard Bulkhead – Basic 11-gauge steel design
- Reinforced Bulkhead – Thicker steel for added strength
- Modular Bulkhead – Allows attachment of accessories


Additional information:
Western Highways Traffic Safety Products highlights their quality construction, and the Heavy Duty Bulkhead exemplifies their focus on building robust trucks. The 11-gauge steel is thicker than standard truck panels, providing extra protection.
The bulkhead’s solid construction likely offers additional impact resistance, protecting the cab if the MASH Attenuator is struck by a vehicle. This is a critical safety feature for highway trucks, and Western Highways’ emphasis on saving lives suggests they prioritize such protective elements.
Practical Application:
During a high-speed collision with the MASH Attenuator, the Heavy Duty Bulkhead prevents debris or equipment from crashing into the cab, keeping the driver safe.
