aluminum tube fabric a-frames are frequently used outdoors as the aluminum frame and dye sublimated fabric graphics won't be harmed by moisture, so they are great in any weather. when used in windy weather, sandbags or other types of weight can be used on the bottom cross bars to keep them in place, but since they're heavier and more stable than the pop-up style, these won't be needed in most cases. in addition to outdoor uses, they are also good for use indoors at trade shows and events where they can be placed to direct foot traffic or display marketing messages close to the target audience.
