The following aspects should be considered when selecting the brace of automobile hood:

1. Material: The common materials of automobile cover struts include steel, aluminum alloy and plastic. Steel poles have high strength and durability, and are suitable for supporting large automobile covers. Aluminum alloy strut is light and corrosion-resistant, which is suitable for improving the appearance of cars; Plastic poles are light and easy to install, and are suitable for supporting the cover of small cars. Select the appropriate material according to the actual demand and use environment.

2. Size: Select the brace that matches the size of the car cover to ensure that the cover can be firmly supported without shaking. Too long or too short strut size will affect the support effect. It is suggested to measure the support position size of the cover in advance and select the appropriate strut size.

3. Durability: Choose a brace with good durability, which can keep the effect of firmly supporting the machine cover for a long time. The poles with poor durability are easy to deform or break, which leads to the failure of normal support of the machine cover and affects driving safety.

4. Installation mode: Considering the installation mode of the strut, there are generally pneumatic, hydraulic and mechanical modes. Choose a brace that is convenient to install, stable and reliable, so as to ensure that it will not loosen or fall off after installation.

5. Brand and quality: select the poles with well-known brands and guaranteed quality to ensure reliable product quality and avoid accidental closure or damage of the machine cover due to the quality problems of poles. It is recommended to choose formal channels to avoid buying inferior products.

Considering the above factors comprehensively, consumers can choose the appropriate automobile hood brace according to the actual demand and use environment to ensure the normal support of the hood and driving safety. When replacing the strut, it is suggested to choose according to the model and specification specified by the automobile manufacturer, or consult the advice of professional technicians to ensure that the suitable strut is selected.
