When the sun is scorching, and when going out shopping, ladies like to bring the beautiful and lightweight Outdoor Patio Umbrella. There are many kinds of umbrellas on the market nowadays, the quality varies, and the price ranges from more than ten yuan to hundreds of yuan. So how to choose a parasol? The following are some precautions for the production of umbrellas:

1. When choosing umbrella surfaces, umbrellas with obviously sparse fabrics generally have poor UV resistance, so consumers should buy them carefully.
2. 
   Due to the shrinkage of the fabric, when buying a parasol, the surface of the umbrella should be large rather than small.
3. The color of the fabric is related to the UV protection performance. Under the same conditions, the darker the fabric, the better the UV resistance. In contrast, black, navy blue, dark green and light blue, light pink, and light yellow have better UV resistance.
4. Before purchasing, you should carefully check the protection grade mark of Custom Leisure Furniture. The "Assessment of Textile Anti-ultraviolet Performance" issued by the General Administration of Quality Supervision, Inspection and Quarantine stipulates that only when the UPF (ultraviolet protection factor value) is greater than 30 and the UVA (long-wave ultraviolet) transmittance is less than 5%, can it be called an anti-ultraviolet product. The standard is "UPF30+"; when the UPF is greater than 50, it indicates that the product has excellent UV protection performance, and the protection level is marked as "UPF50+". Consumers should carefully check the protection level signs when purchasing, and then choose the umbrella that suits them according to the local sun exposure.
