济南卷帘门因结构紧凑、防盗性强，广泛应用于商铺、仓库等场所，其制作需经多环节精细把控，以适应频繁使用与复杂环境。

　　Jinan roller shutter doors are widely used in places such as shops and warehouses due to their compact structure and strong anti-theft capabilities. Their production requires precise control in multiple stages to adapt to frequent use and complex environments.

　　原材料选择与预处理是基础。帘片多选用 0.3-0.8 毫米镀锌钢板或铝合金板材，镀锌钢板适合潮湿环境，铝合金适合对外观要求高的场所；复合板材则兼具保温隔音性。导轨与卷轴用型钢制作，卷轴需经调质处理增强强度。原材料进场后，钢板需去油污锈迹，型材切割后打磨去毛刺。

　　The selection and pretreatment of raw materials are the foundation. 0.3-0.8mm galvanized steel plates or aluminum alloy plates are commonly used for curtains. Galvanized steel plates are suitable for humid environments, while aluminum alloys are suitable for places with high appearance requirements; Composite panels also have thermal insulation and sound insulation properties. The guide rail and scroll are made of steel sections, and the scroll needs to undergo quenching and tempering treatment to enhance its strength. After the raw materials enter the site, the steel plates need to be cleaned of oil and rust, and the profiles need to be cut and polished to remove burrs.

　　帘片加工成型是关键。数控剪板机将板材裁成条料，精度控制在 ±1 毫米内。条料经辊压成型机压制成弧形或槽型帘片，兼顾强度与灵活性。需实时监测尺寸，偏差时及时调整。防盗卷帘门会嵌入加强筋，连接后处理焊接点防腐蚀。

　　The processing and shaping of curtain pieces is crucial. The CNC shearing machine cuts the sheet metal into strips with an accuracy controlled within ± 1 millimeter. The strip material is pressed into curved or groove shaped curtains by a roll forming machine, balancing strength and flexibility. Real time monitoring of dimensions is required, and adjustments should be made promptly in case of deviations. The anti-theft rolling shutter door will be embedded with reinforcing ribs, and the welding points will be treated to prevent corrosion after connection.

　　表面处理提升美观与耐腐蚀性。镀锌处理形成不小于 80 微米的锌层，适合户外；喷涂处理先磷化增强附着力，再用静电粉末或氟碳喷涂，颜色可定制，氟碳涂层耐候性强，适合临街商铺。部分高端产品会做木纹转印，兼具强度与美观。

　　Surface treatment enhances aesthetics and corrosion resistance. Galvanizing treatment forms a zinc layer of not less than 80 microns, suitable for outdoor use; Spray treatment involves phosphating to enhance adhesion, followed by electrostatic powder or fluorocarbon spraying. The color can be customized, and the fluorocarbon coating has strong weather resistance and is suitable for street facing shops. Some high-end products will undergo wood grain transfer printing, which combines strength and aesthetics.

　　传动系统组装保障运行顺畅。卷轴与轴承座配合，轴承选耐磨型，安装时涂润滑脂减噪。电机与减速器连接需高同心度，偏差不超 0.1 毫米，连接后检查是否卡滞。导轨安装保证垂直度与平行度，间距误差 ±2 毫米，内侧贴耐磨条，底部装限位块防损坏。

　　The assembly of the transmission system ensures smooth operation. The scroll is matched with the bearing seat, and wear-resistant bearings are selected. Lubricating grease is applied during installation to reduce noise. The connection between the motor and the reducer requires high concentricity, with a deviation of no more than 0.1 millimeters. After connection, check for any jamming. The installation of guide rails ensures verticality and parallelism, with a spacing error of ± 2 millimeters. Wear resistant strips are attached to the inner side, and limit blocks are installed at the bottom to prevent damage.

　　帘片连接与整体组装整合部件。帘片通过铰链或嵌套结构连接，铰链连接适合弧形轨道，嵌套结构抗风性强，连接点涂防锈油。帘片固定在卷轴上，螺栓连接便于维修，焊接更牢固。安装限位器控制升降行程，确保。

　　Curtain connection and integral assembly components. The curtain pieces are connected by hinges or nested structures. The hinge connection is suitable for curved tracks, and the nested structure has strong wind resistance. The connection points are coated with anti rust oil. The curtain is fixed on the scroll, bolted for easy maintenance, and welded more firmly. Install limiters to control the lifting stroke and ensure safety.

　　装置与调试是环节。防坠装置在帘片坠落时能迅速制动，制动距离不超 10 厘米。红外感应装置可检测障碍物并反向运行。连续升降门体 10-20 次，检查运行平稳性、噪音、电机温升及限位准确性，达标后方可完成制作。

　　Safety devices and debugging are the final steps. The anti fall device can quickly brake when the curtain falls, with a braking distance not exceeding 10 centimeters. The infrared sensing device can detect obstacles and operate in reverse. Finally, lift and lower the door body continuously 10-20 times, check the running stability, noise, motor temperature rise, and limit accuracy. Only after meeting the standards can the production be completed.

　　济南卷帘门制作围绕 “、耐用、顺畅”，各环节细节把控使成品能适应本地气候，提供可靠防护。

　　Jinan roller shutter door production revolves around "safety, durability, and smoothness", with detailed control of each link to ensure that the finished product can adapt to the local climate and provide reliable protection.
