The most important factor to consider when choosing the best steel gazebo is the type of steel used for the gazebo frame. You will want to pick a steel gazebo made from galvanized steel to prevent rusting and corrosion during exposure to the elements. If you are choosing a collapsible steel gazebo, make sure you choose one that is made with other durable materials that can be compacted and stored easily, such as nylon or vinyl. Avoid materials such as cotton that will be susceptible to developing mold and mildew, and if you plan on moving the structure frequently, avoid heavy materials such as canvas.
Galvanization is a process through which steel is coated with another material, commonly zinc or aluminum, to prevent it from rusting when exposed to moisture. Your steel gazebo should be made from galvanized steel to keep it from rusting during exposure to rain, snow, or other types of moisture. If the steel is not galvanized, be sure it has been treated in some other way to protect it from rust.
Steel is a wise choice of material for a gazebo, both collapsible versions and permanent structures, because it is quite strong and can be bent back into shape should it become damaged or bent for any reason. Other types of metals, such as aluminum, are lighter; should the aluminum become bent for any reason, it cannot be easily bent back into place without risking permanent damage. When choosing the best steel gazebo, you should try to choose one with thicker gauge steel to avoid the possibility of damage and bending, unless you are looking for a lightweight gazebo, in which case you can choose a thinner gauge of steel. Permanent structures should be made from heavier gauge steel, however, since it is unlikely that you will need to move the structure at any time.
Before purchasing a steel gazebo, be sure to determine the size you need as well as the level of visual appeal you are trying to accomplish. Steel gazebos can be quite simple or more elaborate, and the price of the gazebo may depend on its decorative features. The size of the gazebo will also determine its price. Be sure to consider both round and square gazebos and consider which would work best with the space given.
