Market umbrellas and divided into two lightweight alloy skeleton skeleton, the general idea of ??the selection of lightweight skeleton, due to the use of lightweight aluminum frame or add acrylic material, light weight, long life expectancy, the number of ordinary life can reach 6 years or so, but the drawback is that the skeleton thick robust; alloy skeleton slim, pencil umbrella generally used sun umbrellas, but the weight of the robust than thick umbrella also heavy rain and I can not use, due to the simple iron rust, so if used as an umbrella , life expectancy as long as a year, although the low purchase price, but life expectancy is low. 3, multi-folding aluminum frame are generally chosen, feel good, is not significant on the bag, easy to take, but this sturdy umbrella poor, only a simple shade, if they were suddenly winds, very simple damage . A folding steel skeleton are generally the most strong, but the volume is "great", not storage. 4, parasol best not used as an umbrella, it will greatly shorten the life expectancy using umbrellas, sun umbrellas due to relatively umbrella umbrella umbrella light, together, parasol and umbrella fabric is different, can not stand the rain leaching.
