No rust on your patio
Patio umbrella factories face a big problem. Metal ribs rust, and then the fabric tears. Customers return many products. Our factory is in Shangyu Zhangzhen, the heart of the umbrella industry. We make 500,000 Patio Umbrella Ribs every month. An exporter in Zhejiang used our product. Their return rate dropped from 8% to 1.5%. Shaoxing Longfan started in 2021. We have 14 patents for our technology.

The ribs can bend 30° in the wind. This absorbs energy and protects the fabric. The double grooves keep the fabric in place during sewing. Fiberglass does not rust. After 5 years of use, the ribs are still good. The stainless steel rivets at the connection are tight. The Patio Umbrella Ribs are very easy to sew.
