　　Umbrellas are daily necessities for people. Everyone should have the experience of buying umbrellas. But have you really understood umbrellas when you buy them? Do you think you can choose an umbrella? Is the umbrella you choose suitable for you? Do you know what to pay attention to when choosing an umbrella? Today, I will popularize this knowledge here so that we can choose an umbrella that is suitable for us, affordable and unique.In view of the actual needs of society, carbon fibre umbrella We need to change some original problems to better serve the society and benefit people. https://topumbrella.cc/

　　

　　umbrella quality

　　

　　The quality of the ribs:

　　

　　determines the quality of an umbrella. The ribs are mainly divided into fiber ribs and steel ribs. Fiber rib umbrellas are more wind-resistant and rust-proof. The number of ribs is divided into 8 ribs, 10 ribs, 16 ribs, etc. The more the better.

　　

　　The density of the umbrella cloth:

　　

　　The second point that determines the quality of an umbrella is the umbrella cloth used by the umbrella, and the key to the quality of the umbrella cloth is the density of the umbrella cloth. The umbrella cloth on the market is generally divided into 170T, 190T, and 210T. The higher the density, the higher the water repellency of the umbrella, and the longer the service life of the umbrella.

　　

　　Straight-pole umbrellas are more durable:

　　

　　Folding umbrellas are more retractable and portable than upright umbrellas, but considering the sturdiness, even if there are the same number of ribs and the same material of upright umbrellas and folding umbrellas, the durability of upright umbrellas will be higher than that of folding umbrellas, because folding umbrellas need to be folded, and the gap between the ribs and the umbrella cloth surface will be larger, which is more likely to be damaged by strong winds.

　　

　　Turn the top of the umbrella to see the tightness:

　　

　　Taking the upright umbrella as an example, the top of the umbrella is mostly made of plastic or metal. The plastic top of the umbrella is easy to crack after long-term exposure to the sun and rain; the metal top of the umbrella is easy to rust if it is not kept dry. When purchasing, you can use your fingers to slightly turn it. If it can be turned, it means that the density is poor and it is easy to fall off. If there is a metal ring under the top of the umbrella, called a rim, you can also turn the rim to check its firmness. Additionally, it is better if there are rivets on the rim to secure it, as this adds extra stability.

　　

　　Turn the umbrella to test the handle:

　　

　　Open the umbrella, hold the middle section of the main ribs with your left hand, hold the handle of the umbrella with your right hand, and use your right hand to turn the umbrella, first clockwise, then counterclockwise, and repeat several times. In this way, you can know whether the handle and the ribs are firm.

　　

　　Folding and pulling trial:

　　

　　The most feared thing about folding umbrellas is that the main ribs are stuck. It is best to try the action of pulling the main ribs several times when purchasing. If it feels smooth when pulling, the quality of the umbrella is good. If it feels stuck, don¨t buy it.
