What is the best material for umbrella bone?
The umbrella bone refers to a skeleton to support the umbrella, the previous umbrella bone is mostly wood, bamboo umbrella bone, then there are iron bone, steel bone, aluminum alloy bone (also known as Fiber bone), electric bone and resin bone, they mostly appear in the form of shrinkage bone, with the characteristics of carrying light and convenient.
Steel bone is the strongest and most durable, not easy to break, longer service life. Iron bone is tough and not easy to break, good wind resistance, is easy to rust over time. Aluminum alloy bone weighs light and the price is cheap. Chemical fiber bone light weight, durable, wind resistance is stronger. Carbon fiber bone light weight, wind resistance in general, the price is the highest of all materials. Electric bone and resin bone are relatively light and portable.
The disadvantage is that they are easy to fold and have poor wind resistance.
Is it better to have more bones in an umbrella?
The number of bones is not fixed, but adjusted according to different needs, there is no absolute statement whether more or less is better.
For the quality of the umbrella not only depends on how many bones, but also depends on what material is used to make.
How many umbrella bones can not directly identify the umbrella good or bad, but the more the number of umbrella bones, the more comprehensive the umbrella, the more beautiful the umbrella bones, the more the number of roots relatively firm, the more roots are relatively firm, but also relatively heavy. The full skeleton is generally 6-8, the most can reach 24 bones, mainly used in the straight pole of the two full.
The sunshade is generally 6 roots, 8 roots mainly, we most often see 8 bones of iron and steel bones. 8 bones of 16 bones in two umbrellas and sunny two umbrellas used more, but
In order to reduce the cost now there are many clear two umbrellas with 7 bones to do. 6 bones 7 bones in the shade of the ultra-light umbrella used more, the material mostly with aluminum alloy bone (fiber bone) resin bone.
Lastly, the price of resin bone is relatively high, so often used in high-grade umbrellas. High-grade umbrellas pay attention to style, and will consider the umbrella shape when designing umbrellas.
