交通标志杆制作工艺流程

交通标志杆制作主要分为以下步骤：

‌材料准备‌：选用Q235低碳钢或铝合金等原材料，进行切割下料，精度控制在±0.5mm内。

‌成型加工‌：通过折弯机将钢板或钢管冷弯成型，折弯角度误差≤±0.5°。

‌焊接组装‌：采用二氧化碳气体保护焊，确保焊缝牢固，焊后打磨光滑无毛刺。

‌表面处理‌：先除锈，再进行热镀锌（锌层厚度≥85μm）或喷塑处理，防腐寿命可达15年以上。

‌质量检测‌：检查尺寸精度、防腐性能（盐雾测试）和反光膜附着力，确保符合国标。

‌安装验收‌：基础浇筑强度≥C25，杆体垂直度误差≤1/1000，反光膜无气泡。

The production of traffic sign posts mainly involves the following steps:

Material preparation: Use Q235 low-carbon steel or aluminum alloy and other raw materials for cutting and cutting, with an accuracy controlled within ± 0.5mm.

Forming processing: Steel plates or pipes are cold bent into shape using a bending machine, with a bending angle error of ≤± 0.5 °.

Welding assembly: Carbon dioxide gas shielded welding is used to ensure that the weld seam is firm and polished smooth without burrs after welding.

Surface treatment: First remove rust, then perform hot-dip galvanizing (zinc layer thickness ≥ 85 μ m) or spray coating treatment, and the anti-corrosion service life can reach more than 15 years.

Quality inspection: Check the dimensional accuracy, anti-corrosion performance (salt spray test), and adhesion of reflective film to ensure compliance with national standards.

Installation acceptance: The foundation pouring strength is ≥ C25, the verticality error of the pole body is ≤ 1/1000, and the reflective film has no bubbles.
