济南的庭院、别墅常以铁艺大门彰显独特风格，其制作融合了金属加工工艺与艺术设计，每一步流程都影响着大门的质感与耐用性。结合当地气候与审美需求，铁艺大门的制作需经过严谨的步骤，才能既美观又适应济南的天气特点。

　　The courtyards and villas in Jinan often showcase their unique style with iron gates, which integrate metal processing techniques and artistic design. Each step of the process affects the texture and durability of the gates. Combining local climate and aesthetic needs, the production of wrought iron gates requires rigorous steps to be both aesthetically pleasing and adaptable to the weather characteristics of Jinan.

　　设计与测量是制作的起点。首先需根据安装场地的尺寸，精准测量门洞的宽度、高度及墙体厚度，确定大门的整体规格。济南部分老城区的庭院空间有限，设计时需考虑大门开启方式（平开或推拉）与周边环境的适配性，避免占用过多空间。同时，结合业主的审美偏好，融入花纹、造型等艺术元素，如传统的祥云图案、简约的几何线条，或结合泉城文化的特色纹样。设计图纸需明确各部件的尺寸、连接方式及受力点，确保大门结构稳固，尤其要考虑济南冬季风雪对大门的压力，在关键部位增加承重设计。

　　Design and measurement are the starting points of production. Firstly, it is necessary to accurately measure the width, height, and wall thickness of the door opening based on the size of the installation site, in order to determine the overall specifications of the gate. The courtyard space in some old urban areas of Jinan is limited, and the design needs to consider the adaptability of the door opening method (flat opening or sliding) to the surrounding environment to avoid occupying too much space. At the same time, based on the aesthetic preferences of the owners, incorporate artistic elements such as patterns and shapes, such as traditional auspicious cloud patterns, simple geometric lines, or unique patterns of Quancheng culture. The design drawings need to specify the dimensions, connection methods, and force points of each component to ensure the stability of the gate structure, especially considering the pressure of winter wind and snow in Jinan on the gate, and adding load-bearing design in key areas.

　　材料选择与裁剪需兼顾强度与美观。常用材料为低碳钢或花纹钢板，低碳钢可塑性强，适合锻造复杂花纹，且经过处理后能抵御济南的潮湿气候；花纹钢板则自带纹理，可简化表面装饰工序。根据设计图纸，用切割设备将钢材裁剪成门框、花件、面板等部件，切割时需保证切口平整，避免毛刺影响后续加工。对于需要弯曲或锻造的部件（如弧形门框、立体花饰），需采用加热锻造工艺，将钢材加热至红热状态后，用模具压制成型，冷却后进行修整，确保造型精准。

　　Material selection and cutting should balance strength and aesthetics. The commonly used materials are low-carbon steel or patterned steel plates. Low carbon steel has strong plasticity and is suitable for forging complex patterns. After treatment, it can resist the humid climate of Jinan; The patterned steel plate comes with its own texture, which can simplify the surface decoration process. According to the design drawings, use cutting equipment to cut steel into components such as door frames, decorative parts, and panels. During cutting, ensure that the cut is flat to avoid burrs affecting subsequent processing. For components that require bending or forging, such as curved door frames and three-dimensional flower decorations, the heating forging process should be used. After heating the steel to a red hot state, it should be pressed into shape with a mold, cooled, and then trimmed to ensure precise shaping.

　　焊接与组装是塑造大门骨架的关键。先将门框的竖框与横框焊接成整体框架，焊接点需饱满牢固，焊后用角磨机打磨平整，避免凸起影响美观或造成磕碰。接着安装花件与装饰部件，根据设计图纸在框架上定位后，采用点焊固定，调整位置确认无误后再满焊，确保花件与框架连接紧密，在济南的强风天气中不会松动。对于有玻璃或板材镶嵌的大门，需预留相应的卡槽，卡槽尺寸需精准，保证镶嵌物安装后牢固不晃动。组装完成后，检查大门的平整度，用水平仪校准，确保门框垂直、对角线误差控制在 5 毫米以内，避免安装后出现开关不畅。

　　Welding and assembly are the key to shaping the framework of the gate. First, weld the vertical and horizontal frames of the door frame into a complete frame. The welding points should be full and firm. After welding, use an angle grinder to polish them flat to avoid protrusions that affect the appearance or cause collisions. Next, install the floral and decorative components. After positioning them on the frame according to the design drawings, use spot welding to fix them. Adjust the position and confirm that it is correct before fully welding to ensure that the floral components are tightly connected to the frame and will not loosen in strong wind weather in Jinan. For doors with glass or panel inlay, corresponding card slots should be reserved, and the card slot size should be precise to ensure that the inlay is firmly installed without shaking. After assembly, check the flatness of the door and calibrate it with a spirit level to ensure that the vertical and diagonal errors of the door frame are controlled within 5 millimeters, in order to avoid smooth opening and closing after installation.

　　表面处理决定了大门的耐候性与美观度。首先进行除锈处理，用砂纸打磨或喷砂工艺去除钢材表面的氧化层，露出金属本色，为后续涂装打好基础 —— 这一步对济南尤为重要，能减少潮湿环境下的锈蚀风险。除锈后涂刷防锈底漆，底漆需均匀覆盖所有表面及焊接点，形成隔绝水汽的第一道屏障。待底漆干燥后，根据设计选择面漆颜色（如黑色、古铜色），采用喷涂或刷涂方式施工，面漆需至少涂刷两遍，保证色泽均匀。对于追求复古质感的大门，可进行做旧处理，通过局部打磨、擦拭深色药剂，营造岁月沉淀的韵味，最后涂刷清漆增加光泽度并增强耐磨性。

　　The surface treatment determines the weather resistance and aesthetics of the gate. Firstly, rust removal treatment is carried out by sanding or sandblasting to remove the oxide layer on the surface of the steel, exposing the natural color of the metal and laying a foundation for subsequent painting - this step is particularly important for Jinan as it can reduce the risk of corrosion in humid environments. After rust removal, apply anti rust primer, which should evenly cover all surfaces and welding points to form the first barrier against water vapor. After the primer dries, choose the color of the topcoat (such as black or bronze) according to the design, and apply it by spraying or brushing. The topcoat should be applied at least twice to ensure uniform color. For doors that pursue a vintage texture, they can be treated with a distressed finish by locally polishing and wiping off dark agents to create a lingering charm of time. Finally, a clear coat can be applied to increase glossiness and enhance wear resistance.
