普通建筑、地产小区项目：以常规镀锌、普通钢制桥架为主，优先核对载荷、接地、屏蔽性能；项目有消防要求，同步匹配防火桥架，确认消防验收相关资料。

Ordinary building and real estate community projects: mainly using conventional galvanized and ordinary steel cable trays, with priority given to checking load, grounding, and shielding performance; The project has fire safety requirements, and the fire-resistant bridge frame should be matched synchronously to confirm the relevant materials for fire safety acceptance.

化工、冶金、沿海高腐蚀项目：可根据腐蚀等级选择热浸锌、不锈钢、玻璃钢、铝合金桥架，核心核验防腐工艺与材质牌号，不可选用普通电镀锌产品。

Chemical, metallurgical, and coastal high corrosion projects: Hot dip galvanizing, stainless steel, fiberglass reinforced plastic, and aluminum alloy cable trays can be selected according to the corrosion level, with a focus on verifying anti-corrosion processes and material grades. Ordinary electroplated galvanized products cannot be used.

大型厂房、高铁站、体育场馆大跨度空间：优先评估大跨距桥架，结合实际跨距计算载荷，确认支架配套方案，保障长期使用结构稳定。

Large scale factory buildings, high-speed railway stations, and sports venues with large-span spaces: Priority should be given to evaluating large-span bridge structures, calculating loads based on actual spans, confirming support matching schemes, and ensuring long-term structural stability.

数据中心、医药、航空机房场景：网格桥架、不锈钢桥架较为常用，关注散热、线缆防护、洁净要求。

Data center, pharmaceutical, and aviation data center scenarios: Grid cable trays and stainless steel cable trays are commonly used, and attention should be paid to heat dissipation, cable protection, and cleanliness requirements.

光伏电站、新能源项目：户外工况优先选用热浸锌、玻璃钢等耐候防腐产品，评估抗老化能力。

Photovoltaic power station, new energy project: hot dip galvanizing, glass fiber reinforced plastic and other weather resistant and anti-corrosion products are preferred for outdoor working conditions, and the anti-aging ability is evaluated.

医院、公共建筑：兼顾防火、洁净需求，可选用防火桥架、不锈钢桥架，满足消防与卫生环境要求。

Hospitals and public buildings: Taking into account the needs of fire prevention and cleanliness, fire-resistant cable trays and stainless steel cable trays can be selected to meet the requirements of fire protection and hygiene environment.

通用采购参考要点：明确项目腐蚀等级、电缆总重量、实际跨距、防火设计要求；优先核验供应商资质、材质报告、检测文件；标准化产品优先评估批量一致性，非标项目做好图纸技术确认；将交付周期匹配施工计划，明确全流程技术对接渠道。

General procurement reference points: Clearly define the corrosion level of the project, total weight of the cable, actual span, and fire protection design requirements; Prioritize verifying supplier qualifications, material reports, and testing documents; Prioritize the evaluation of batch consistency for standardized products, and ensure technical confirmation of drawings for non-standard projects; Match the delivery cycle with the construction plan and clarify the channels for technical integration throughout the entire process.
