Legacy Durability: Circle D Steel Pickup Flatbeds
Replacing a standard factory pickup box with a heavy-duty Circle D flatbed gives your vehicle maximum deck strength and long-term structural integrity. To prevent deck sagging ("oil-canning") under heavily palletized or gooseneck loads, Circle D utilizes heavy-gauge 4" x 2" rectangular tubing crossmembers spaced on ultra-tight 12-inch centers, backed by 3-inch structural channel stringers and a heavy steel treadplate deck.
Popular Circle D Models: Standard & Special Deluxe (SD)
We carry Circle D’s premier steel flatbeds engineered for SRW, DRW, and Commercial Cab & Chassis trucks:
- Circle D Standard Flatbed: The classic steel replacement body equipped with a 3" x 2" rectangular tubing louvered headache rack, a recessed gooseneck hitch plate with a hinged flush lid, integrated side stake pockets, steel tie straps, and rubber-mounted LED lights.
- Circle D Special Deluxe (SD) Flatbed: Purpose-built for heavy commercial towing. Adds tapered rear corners for significantly improved turning clearance when pivoting heavy trailers, an integrated rear receiver bumper, a factory-pre-installed 30,000 LB gooseneck ball, and an extra set of LED lights embedded in the headache rack.
- Optional Point-of-Sale Add-Ons: Customize your bed with optional fold-down side rails that instantly convert the open deck into a secure stake-body, underbody toolboxes, and poly mud flaps.
