一、前期准备阶段

　　1、 Pre preparation stage

　　表面清洁处理

　　Surface cleaning treatment

　　在开始涂装作业之前必须彻底清除铁艺护栏表面的灰尘油渍等污染物，建议使用专业清洁剂配合无尘布进行深度清洁，以确保后续漆层能够均匀牢固地附着在金属基材上。

　　Before starting the painting operation, it is necessary to thoroughly remove dust, oil stains, and other pollutants from the surface of the wrought iron guardrail. It is recommended to use professional cleaning agents and dust-free cloths for deep cleaning to ensure that the subsequent paint layer can be evenly and firmly attached to the metal substrate.

　　基材打磨工序

　　Substrate polishing process

　　采用砂纸、钢丝球或电动打磨设备对护栏表面进行系统性打磨处理，通过创造适当粗糙度的基底面来显著提升油漆涂层与金属之间的结合力，这是确保涂装持久性的关键步骤。

　　Using sandpaper, steel wire balls, or electric polishing equipment to systematically polish the surface of the guardrail, significantly improving the adhesion between the paint coating and the metal by creating a base surface with appropriate roughness. This is a key step in ensuring the durability of the coating.

　　二、涂装实施流程

　　2、 Painting implementation process

　　底漆涂布工艺

　　Primer coating process

　　在正式涂刷面漆前需要先施作具有防腐防锈功能的专用底漆，这不仅能优化面漆的流平性和覆盖效果，更能通过化学转化层显著增强涂层体系的整体附着力，建议根据环境腐蚀程度选择合适的底漆类型与色系。

　　Before formally applying the topcoat, a specialized primer with anti-corrosion and anti rust functions needs to be applied first. This not only optimizes the leveling and coverage effect of the topcoat, but also significantly enhances the overall adhesion of the coating system through a chemical conversion layer. It is recommended to choose the appropriate primer type and color scheme according to the degree of environmental corrosion.

　　面漆施工要点

　　Key points for topcoat construction

　　待底漆完全固化后即可进行面漆涂装，应选用耐候性优异的专用金属漆，使用优质毛刷或滚筒工具采用十字交叉法施工，确保漆膜厚度均匀且无流挂现象，特别注意边角部位的覆盖完整性。

　　After the primer is completely cured, the topcoat can be applied. Special metal paint with excellent weather resistance should be selected, and high-quality brushes or roller tools should be used for cross cross construction to ensure uniform film thickness and no sagging phenomenon. Special attention should be paid to the integrity of the coverage of the corners.

　　装饰细节处理

　　Decorative detail processing

　　对于护栏上的雕花镂空等复杂造型部位，需提前选用特制细尖毛笔进行预涂装，沿着花纹轮廓精细作业以避免出现漏涂死角，建议在光线充足环境下操作以保证细节处理精度。

　　For complex shapes such as carved and hollowed out parts on guardrails, it is necessary to use a specially designed fine tipped brush for pre coating in advance. Fine operation should be carried out along the contour of the pattern to avoid blind spots. It is recommended to operate in a well lit environment to ensure the accuracy of detail processing.

　　面漆强化涂层

　　Topcoat reinforced coating

　　为获得更理想的装饰保护效果，可在首层面漆表干后追加第二遍涂装，这样既能增强色彩饱和度呈现更鲜艳的视觉效果，又能通过增加整体漆膜厚度来提升护栏的长期防护性能。

　　To achieve a more ideal decorative protection effect, a second coat of paint can be added after the first layer of topcoat has dried. This can enhance color saturation and present a more vivid visual effect, while also improving the long-term protective performance of the guardrail by increasing the overall paint film thickness.
