J&B’s standard bodies possess many upgrades others do not offer. We use premium roll-up doors, a 2” pine floor, and our rear door frames and uprights are constructed in conjunction with galvanneal steel. Our FRP walls are gel coated on both sides, whereas most companies only use gel coat on one side. All of our fasteners are zinc-plated to protect against corrosion. We use heavy-duty cast corner caps. Level entry rear threshold. All J&B’s bodies are tailored to our customers' specific needs.
