Which umbrella bone is more durable and windproof?

The aluminum alloy material is generally rigid but has good corrosion resistance, is not easy to rust, and is relatively light in weight. However, it is fragile, easy to break, and has poor wind resistance.

The iron is hard and not easy to break, and the wind resistance is general. However, too thin umbrella bone is also easy to break. The beauty is that it is easy to rust. It needs good wind resistance, and the umbrella bone will be slightly bulky.

Steel has high strength, good plasticity, good toughness, impact resistance and good tensile strength. It is not easy to break and has a relatively long service life.

After the glass fiber is drawn and shaped by a special process, it has strong toughness, is not rusty and not easy to deform, and is also very light.
