1. 安全性：河道護欄的先要目標是確保人們的安全。因此，護欄的高度和結構設計能夠有效防止人員從護欄中跌落。根據河道的高度和位置，選擇適當的高度和結構設計的護欄。

1. Safety: The primary goal of river guardrails is to ensure people's safety. Therefore, the height and structural design of the guardrail can effectively prevent personnel from falling from the guardrail. Select appropriate height and structural design guardrails based on the height and location of the river channel.

2. 耐久性：河道護欄處于室外環境中，需要承受各種天氣條件的考驗。確保選擇耐久性好的不銹鋼材質，以及經過良好防銹處理的護欄，可以確保護欄長時間使用而不受損。

2. Durability: The river guardrail is located in an outdoor environment and needs to withstand various weather conditions. Make sure to choose durable stainless steel materials and guardrails that have undergone good rust prevention treatment to ensure that the guardrails are protected from damage during long-term use.

3. 美觀性：河道護欄不僅僅是功能性的設施，也是城市景觀的一部分。選擇外觀設計簡潔、符合城市風格的護欄，能夠提升河道的美觀度，與周圍環境相協調。

3. Aesthetics: River guardrails are not only functional facilities, but also a part of the urban landscape. Choosing guardrails with a simple and urban style design can enhance the aesthetics of the river and coordinate with the surrounding environment.

4. 通風性：河道護欄往往位于水域附近，當河道水位上升時，水流會通過護欄。選擇適當間隔的護欄，能夠確保水流的暢通，并減少流經護欄時產生的沖擊力。

4. Ventilation: River guardrails are often located near water bodies, and when the water level in the river rises, water flows through the guardrails. Choosing appropriately spaced guardrails can ensure smooth water flow and reduce the impact force generated when passing through the guardrails.

5. 安裝便捷性：選擇易于安裝和維護的護欄，可以降低安裝成本和維護費用。不銹鋼材質的護欄通常較輕便，并且安裝過程相對簡單。

5. Installation convenience: Choosing guardrails that are easy to install and maintain can reduce installation and maintenance costs. Stainless steel guardrails are usually lightweight and the installation process is relatively simple.

6. 國家標準合規性：選擇符合國家相關標準的護欄，可以確保護欄質量和安全性符合規定。

6. National standard compliance: Choosing guardrails that comply with relevant national standards can ensure that the quality and safety of the guardrails comply with regulations.

7. 成本考慮：根據預算限制和需求，選擇性價比高的不銹鋼河道護欄。護欄的價格隨著材質、設計和規格的不同而有所差異，需要綜合考慮價格和質量。

7. Cost considerations: Based on budget constraints and needs, choose stainless steel river guardrails with high cost-effectiveness. The price of guardrails varies with different materials, designs, and specifications, and requires a comprehensive consideration of price and quality.
