Light frame for food delivery boxes
Shaoxing Longfan started in 2021. We make fiberglass products. Delivery riders carry heavy food boxes. The boxes need to be light. But they also need to be strong. So we use hollow fiberglass tubes. The outer diameter is 8.0 mm. The inner diameter is 6.0 mm. The wall thickness is 1.0 mm. The tube is 40% lighter than solid rod. A supplier for a major delivery platform bought our 8.0 Hollow Delivery Box Support Frame. They calculated that each box is 200 grams lighter. Riders can do more deliveries. They now buy 100,000 frames per year. We have 14 patents. Our annual production is 3000 tons.
Hollow tubes and connector joints
We use hollow fiberglass tubes. Outer diameter is 8.0 mm. Inner diameter is 6.0 mm. Wall thickness is 1.0 mm. The tubes are straight. Some tubes are bent into curves. The tubes connect with plastic connectors. The connectors are T-joints, L-joints, and cross joints. The connectors are made of PA66 with 30% fiberglass. They are very strong. The frame forms a box shape. The size is custom. A common size is 40 x 30 x 30 cm. The whole frame weighs less than 400 grams.

Easy to assemble and repair
The frame comes as a kit. You push the tubes into the connectors. No glue is needed. The friction fit holds them. You can assemble a frame in 2 minutes. If a tube gets damaged, you replace just that tube. You do not need to buy a whole new frame. The connectors are reusable. The frame can also be taken apart for storage. This is good for riders who have multiple boxes.
