Flexible rods for softbox frames
Shaoxing Longfan started in 2021. We make fiberglass products. Softboxes need rods to hold the diffuser fabric. The rods go into the corners of the softbox. They push the fabric out. The fabric becomes flat and smooth. Metal rods can scratch the fabric. They are also heavy. So we use thin fiberglass rods. The diameter is 2.5 to 3 mm. They are very light. They are also smooth. A photography accessory factory in Shenzhen bought our Softbox Diffuser Rods. They said assembly time went down by 30%. Their softboxes sell very well on Amazon. We have 14 patents. Our annual production is 3000 tons.
Pre-bent rods and smooth surface
We use solid fiberglass rods. The diameter is 2.5 to 3 mm. The length is 200 to 800 mm. The length depends on the softbox size. Each rod is pre-bent. The bend is slight. When you insert the rod into the softbox corner, the rod pushes against the fabric. The fabric becomes flat and smooth. The rod surface is smooth. It will not scratch the diffuser fabric. The rod ends are rounded. They will not poke through the fabric.

The rods are very flexible. They bend easily. But they also return to their shape. You can use them thousands of times. The rods will not lose their spring. The length tolerance is very tight. Each rod is cut to the exact length. This makes assembly easy. You do not have to force the rods. The Softbox Diffuser Rods are very consistent.
Light weight and easy storage
A full set of rods weighs less than 20 grams. That is for 4 to 8 rods. The softbox becomes very light. You can carry it anywhere. The rods are small. They fit into the softbox bag. You can also replace a single rod. If one rod gets lost, you order just one. You do not need to buy a whole new set.
