Automatic straight umbrellas are typically constructed from durable materials to withstand everyday use and adverse weather conditions. Some of the most common and durable materials used in the construction of automatic straight umbrellas include:

1. Canopy Fabric: The canopy fabric is a crucial component of the umbrella, and durable materials such as polyester, nylon, or pongee fabric are commonly used. These materials are water-resistant, quick-drying, and provide protection against UV rays, making them suitable for use in both rain and sunshine.

2. Frame Material: The frame of an automatic straight umbrella is usually made from metal or fiberglass. Metal frames, such as steel or aluminum, provide strength and stability, while fiberglass frames offer flexibility and durability, making them resistant to bending or breaking in strong winds.

3. Ribs: Ribs are the supports that extend from the shaft to the canopy and hold the umbrella's shape. They are typically made from materials such as fiberglass, aluminum, or steel. Fiberglass ribs are lightweight, flexible, and resistant to breaking, while aluminum and steel ribs offer durability and strength.

4. Shaft: The shaft of an automatic straight umbrella can be made from various materials, including steel, aluminum, or fiberglass. Steel shafts provide strength and stability, while aluminum shafts are lightweight and corrosion-resistant. Fiberglass shafts offer flexibility and durability, making them suitable for withstanding windy conditions.

5. Handle: The handle of an automatic straight umbrella is often made from materials such as rubber, plastic, or wood. Rubber or plastic handles offer a comfortable and non-slip grip, while wooden handles provide a classic and aesthetic appeal.
