1：钢材厚度识别：

1: Steel thickness identification:

听声法：通过手指对济南集装箱钢板的敲打，0.8--1.5mm的材料声音清脆，材料越薄，声乐越脆，2-3mm材料敲击起来给人一种厚重的感觉，4-6mm材料有种敲击在实体上的感觉，具体还需要根据实际经验积累甄别。

Listening method: By tapping the Jinan container steel plate with fingers, the sound of 0.8-1.5mm material is clear and crisp. The thinner the material, the more crisp the vocal music is. The 2-3mm material gives a heavy feeling when struck, while the 4-6mm material has a feeling of hitting on the solid. The specific needs to be determined based on actual experience accumulation.

外观成型法：薄材料成型角尖锐，越厚的材料圆角越大，因为加工工艺的原因通常集装箱板材都是通过冷弯成型，越厚的材料成型后圆角越大。

Appearance forming method: Thin materials have sharp forming angles, and thicker materials have larger rounded corners. Due to processing technology, container plates are usually formed by cold bending, and thicker materials have larger rounded corners after forming.

2：喷漆质量识别：

2: Painting quality identification:

检查施工死角区域的喷涂质量如：集装箱上部，下部，阴角，阳角，百叶窗及隐藏部位。

Focus on inspecting the spraying quality of the construction dead corner areas, such as the upper and lower parts of the container, internal and external corners, louvers, and hidden parts.

焊道毛边处理不合格示意

Schematic diagram of unqualified、遗漏、气泡、划痕、污染、锈迹。

Check for the following phenomena: particles, flow marks, omissions, bubbles, scratches, pollution, rust.

LOGO清晰、无毛边

Clear logo without burrs

以上部位做的都很到位的工厂，质量管控很到位了，也就没必要浪费时间使用工具二次复检了。

A factory that has done all the above parts well and has implemented quality control measures, there is no need to waste time using tools for secondary inspection.

3：焊道质量

3: Weld bead quality

平整，无漏焊，砂眼，饱满，主要查看每道完整的焊缝断点不宜太多，断点连续处采用退焊，不能形成气孔。胶条安装不合格影响使用寿命。

Flat, without missing welds, sand holes, and plump. The main inspection is to ensure that there are not too many complete weld breakpoints in each weld seam. The continuous breakpoints should be welded back to prevent the formation of pores. The unqualified installation of the adhesive strip affects its service life.

4：打胶质量

4: Gluing quality

龟裂、漏打、不美观

Cracking, missing or unsightly appearance

5：门窗等安装附件：胶条安装到位、平整、门开关灵活

5: Installation accessories for doors and windows: the adhesive strips are installed in place, flat, and the door switches are flexible

门锁安装合理牢固。

The door lock installation is reasonable and firm.

焊道平顺，附件安装到位

Smooth welding bead, accessories installed in place

6：标识粘贴是否完整，清晰。

6: Check if the labeling is complete and clear.

安装美观预留线，接口，使用标识是否清晰配电箱、灯、开关、线路是否完整。

Whether the installation of beautiful reserved lines, interfaces, and usage markings are clear, whether the distribution box, lights, switches, and wiring are complete.
