Hongda Sun Umbrella is a very good brand and worth recommending. Hongda is an older parasol brand with a very good reputation for quality. Hongda Umbrella is an old domestic brand, and its quality is naturally guaranteed. Except for the relatively low-looking appearance of the umbrella, the quality and price are great. The price-performance ratio is very high, and you won’t feel bad if you replace it every year.
Hongda parasol products are exported to Japan, Southeast Asia, Europe and the United States, and have received many awards from local governments. In 1990, they won the title of National Foreign Investment "Double Excellent" Enterprise. Because of the reliable quality of this top parasol brand, it passed the "Excellent Ultraviolet Protection" test by the China Institute of Metrology in 2001, and has established a good reputation among consumers.
Related to the sun protection effect is the fabric of the umbrella. Most sun protection umbrellas use black tape and are made of polyester fiber. Professional umbrella cloth is usually coated with black glue. The density of other materials such as colored glue, silver glue, and pearl glue is not as high as that of black glue. Hongda sun umbrellas use high-performance vinyl sunscreen coating.
UPF index is the ultraviolet protection index. Generally speaking, the higher the UPF value, the better the ultraviolet protection effect. The general UPF value of Hongda sun umbrellas is 50, and the UV coefficient rate can reach 99.9. The national standard "Evaluation of UV Protection Performance of Textiles" clearly stipulates products with sun protection functions. Only UPF (ultraviolet protection factor value) is greater than 30.
Only when the UVA (long-wave ultraviolet) transmittance is less than 5 can it be called an anti-UV product. In addition, it is also stipulated that UV protection products should clearly indicate the UPF value, 30 or 50. The higher the value, the better the sun protection effect. These Hongda sun umbrellas can achieve that.
The interior of the umbrella uses a new seventh-generation coating technology, which can effectively prevent ultraviolet rays and heat. When the outdoor temperature is about 35.4 degrees, the temperature inside the umbrella is actually only 19.3 degrees, which is nearly ten degrees lower. It is definitely indispensable when traveling in summer. The UV value tested was 143, but when the instrument was placed in the umbrella, it quickly dropped to 0. The real "0" light transmission is true sun protection!
The 180T high-density impact cloth can form a super waterproof film on the surface, making raindrops fall on it like pearls, and the umbrella surface cannot get in, let alone leakage. . Raindrops on the umbrella will quickly form water droplets and slide down. You only need to flick the umbrella before closing it, and the water will fall away.
