A new and improved transfer cart, specifically for the transfer, delivery and retail display of bottled milk or other packaged goods, has a new base and a new bottle retainer guide. The base is formed of a single elongate strip rolled in to a recurved outwardly convex section and folded and welded into a continuous band with inward facing top and bottom flanges and an outward extending bumper; corner posts are welded into the base band, and base beams are formed into the same cross-section of the base band and have swagged ends fitted into and affixed into the base band. The gate guides hold a liftable gate on the rear of the cart, the guides extend contiguously from the second to the top shelf gusset reinforcing the cart, and shelf tabs extend from each guide over the back of each shelf, and each shelf is welded to a pair of respective tabs to strengthen the cart and enable usage of less steel. A new method of making a cart, and a cart base has the steps of blanking and piercing a flat strip for a base, rolling the base into a recurved convex section, bending the formed section into a closed band, and fabricating the cart using the closed band to save material and time while making a stronger, lighter-weight sanitary cart.
