中东不是「运过去就行」的市场：涂层选择、彩钢板耐候、螺栓温度应力都有讲究。The Middle East is not a ship-and-forget market: coatings, panel weathering and bolt temperature effects all matter.
中东是我们出货量第二大的区域市场，但它的环境条件常被低估。给准备进入这一市场的采购商四点提醒：
一、涂层体系：沿海地区（如吉达、迪拜）属于高盐雾环境，建议 C5-M 级防腐涂层，普通 C3 涂层三到五年就会出现锈蚀。
二、彩钢板：浅色高反射涂层的屋面能降低室内温度 3–5℃，空调费用差异非常可观。
三、温度应力：夏季构件表面温度可达 70℃ 以上，超长构件的螺栓连接要考虑温度变形余量。
四、认证：沙特 SABER/SASO 认证周期约 4–6 周，请把它排进项目时间表，而不是发货前才想起。
The Middle East is our second-largest export region, yet its environment is often underestimated. Four reminders for buyers entering this market:
1. Coatings: coastal areas (Jeddah, Dubai) are high-salinity environments. Specify C5-M corrosion protection — standard C3 systems will show rust within 3–5 years.
2. Panels: light-colored, high-reflectance roof sheets cut indoor temperature by 3–5°C — a very noticeable difference in air-conditioning bills.
3. Temperature effects: member surfaces can reach 70°C in summer; long bolted connections need allowances for thermal movement.
4. Certification: Saudi SABER/SASO takes 4–6 weeks. Schedule it into the project plan — don't remember it right before shipment.
