两跨带 20t 吊车的机械加工厂房开工，C5-M 涂层应对沙漠高温盐雾环境。A two-span machining workshop with 20t cranes is underway — C5-M coatings for desert heat and salt.
中东机械加工厂房项目本周开工：建筑面积 9,800㎡，两跨各 24m，每跨配置 20t 桥式吊车，柱顶标高 11m。
环境适配是本项目重点：厂址距海岸 6 公里，属 C5-M 高腐蚀环境，主结构采用热浸镀锌 + 重防腐涂层双重防护；夏季极端高温下构件温差变形在节点设计中预留余量；屋面选用高反射浅色涂层降低室内温度。
生产排期 10 周，海运 18 天。项目配有 20t 吊车的厂房对吊车梁疲劳设计要求高，全部吊车梁按重级工作制验算，这是此类项目的安全核心。
A machining workshop in the Middle East broke ground this week: 9,800 m², two 24m spans each fitted with a 20t overhead crane, column height 11m.
Environment drives the design: 6km from the coast means C5-M corrosion class, so primary steel gets hot-dip galvanizing plus a heavy-duty coating system; high summer temperatures require thermal-movement allowances in the joints; and a high-reflectance light roof coating keeps indoor temperatures down.
Fabrication runs 10 weeks plus 18 days of shipping. A plant with 20t cranes demands rigorous girder fatigue design — every crane girder is verified for heavy duty, which is the safety core of this project type.
