Introduction to Umbrellas Umbrellas are daily necessities used to shield against rain, sunlight, and wind and snow. They are primarily composed of three parts: the canopy, ribs, and handle, making them the most common portable tool for sun and rain protection in daily life. I. Basic Structure Canopy: Made of waterproof fabric, responsible for blocking rain and sun. Ribs: The supporting framework of the canopy, determining its sturdiness. Handle: The part to hold, available in long handles, folding handles, etc. Top/Bottom Cap: Protective pieces at the top and bottom. II. Main Types Straight Umbrella Sturdy frame and good wind resistance, suitable for heavy rain and strong winds, but bulky and inconvenient to carry. Folding Umbrella Available in two-fold, three-fold, and five-fold styles, compact and lightweight, easy to carry in a bag, and the most commonly used in daily life. Sunshade Umbrella (Parasol) Features a sun protection coating, focusing on UV protection and heat insulation, generally not suitable for heavy rain and strong winds.
