1. Material selection: Common materials for parking sheds include steel, aluminum alloy, and plastic. The steel structure is sturdy and durable, suitable for long-term use; Aluminum alloy is lightweight and has corrosion resistance, suitable for coastal areas; Plastic materials are lightweight, waterproof, and easy to clean, making them suitable for temporary installation or places with low cost requirements. Choose appropriate materials based on actual needs and budget.

2. 尺寸和形狀：根據停車位的大小和數量，選擇適當的停車棚尺寸，確保能夠覆蓋到停放的車輛，并留有一定的空間操作。同時要考慮停車棚的形狀，常見的有單斜頂、雙斜頂和彎曲頂等。選擇適合場地和個人喜好的形狀。

2. Size and shape: Select an appropriate parking shed size based on the size and quantity of parking spaces to ensure coverage of parked vehicles and leave a certain amount of space for operation. 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. 安裝方式：停車棚的安裝方式主要有固定式和可移動式。固定式停車棚需要進行深基礎固定，穩定性好但不易搬遷；可移動式停車棚則較為靈活，可以根據需求更換位置，但需要注意固定和連接方式的牢固性。

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.

4. 防風和防雨性能：停車棚作為戶外設施，需要具備一定的防風和防雨能力。選擇具有結構穩固、材料耐用、防水防曬等特性的停車棚，能夠有效保護車輛免受惡劣天氣的影響。

4. Wind and rain resistance performance: As an outdoor facility, parking sheds need to have certain wind and rain resistance capabilities. Choosing a parking shed with stable structure, durable materials, waterproof and sunscreen characteristics can effectively protect the vehicle from adverse weather conditions.

5. 施工質量和售后服務：選擇信譽良好的供應商或制造商，確保停車棚的質量可靠。詢問關于產品質量保證和售后服務的信息，以便在安裝、維修和保養時能夠得到及時幫助和支持。

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.

在購買停車棚時，建議根據實際需求，綜合考慮以上因素，并在多家供應商之間進行比較和評估。同時，如果不具備安裝技巧和經驗，好委托的安裝師傅進行安裝，確保和穩固性。

When purchasing a parking shed, it is recommended to consider the above factors comprehensively based on actual needs, and compare and evaluate them among multiple suppliers. At the same time, if you do not have installation skills and experience, it is best to entrust a professional installation technician for installation to ensure safety and stability.
