Choose appropriate materials based on actual needs and budget.

2. 尺寸和形状：根据停车位的大小和数量，选择适当的停车棚尺寸，确保能够覆盖到停放的车辆，并留有一定的空间操作。同时要考虑停车棚的形状，常见的有单斜顶、双斜顶和弯曲顶等。选择适合场地和个人喜好的形状。

At the same time, the shape of the parking shed should be considered, commonly including single sloping roof, double sloping roof, and curved roof. Choose shapes that are suitable for the venue and personal preferences.

3. 安装方式：停车棚的安装方式主要有固定式和可移动式。固定式停车棚需要进行深基础固定，稳定性好但不易搬迁；可移动式停车棚则较为灵活，可以根据需求更换位置，但需要注意固定和连接方式的牢固性。

3. Installation method: The installation methods for parking sheds mainly include fixed and movable types. Fixed parking sheds require deep foundation fixation, which has good stability but is not easy to relocate; Mobile parking sheds are more flexible and can be repositioned according to needs, but attention should be paid to the firmness of fixation and connection methods.

Choosing a parking shed with stable structure, durable materials, waterproof and sunscreen characteristics can effectively protect the vehicle from adverse weather conditions.

5. Construction quality and after-sales service: Choose reputable suppliers or manufacturers to ensure reliable quality of parking sheds. Inquire about product quality assurance and after-sales service information in order to receive timely assistance and support during installation, repair, and maintenance.
