What is the frame of an umbrella made of?

Umbrella ribs refer to the skeletons that support the umbrella. In the past, most of the umbrella ribs were made of wood or bamboo. Later, iron ribs, steel ribs, aluminum alloy ribs (also called fibrous ribs), electric ribs and resin appeared.

Bones, they mostly appear in the form of contracted bones, which are light and convenient to carry.

The steel frame is the strongest and most durable, not easy to break and has a long service life.

The iron frame is hard, not easy to break, and has good wind resistance, but it will easily rust over time.

Aluminum alloy frames are lightweight and cheap.

Chemical fiber bone is lightweight, durable and has strong wind resistance.

Carbon fiber bones are light in weight, have average wind resistance, and are the most expensive among all materials.

Electric ribs and resin ribs are relatively lightweight and portable, and are currently used more often in lightweight umbrellas. However, their disadvantages are that they are easy to break and have poor windproof performance.

Therefore, the number of ribs in a sunny or rainy umbrella does not necessarily mean that more is better.

The quality of an umbrella depends not only on how many ribs it has, but also on what material it is made of.

The number of ribs cannot directly determine the quality of an umbrella, but the more ribs the umbrella has, the rounder the umbrella surface will be, and the more beautiful the umbrella will be. The more ribs the umbrella has, the stronger it will be, but it will also be heavier.

Umbrella frames generally have 6-8 frames, and the most can reach 24 frames. They are mainly used in straight umbrellas.

Parasols generally have 6, 7 or 8 legs. The most common ones we see are 8-bone iron and steel frames.

8-rib and 16-rib umbrellas are more commonly used in umbrellas and sun umbrellas, but in order to reduce costs, many sun umbrellas are now made with 7 ribs.

6- and 7-ribs are often used in ultra-light sunshade umbrellas. Most of the materials are aluminum alloy bone (fibrous bone) and resin bone.

However, the price of aluminum alloy bone, fiber bone and resin bone is relatively high, so they are often used in high-end umbrellas.

High-end umbrellas pay attention to style. When designing umbrellas, they will consider the shape of the umbrella and will not consider the number of ribs to reduce costs, so umbrellas with more ribs are better for sunny or rainy umbrellas. Ultra-light umbrellas for sunshade do not need to consider the number of ribs.

How many.
