一、材质选择

1、 Material selection

牌号识别：优先选用 304 奥氏体不锈钢（含 8% 镍），通过磁铁测试初步验证（弱磁或无磁），要求供应商提供材质检测报告（如 SGS 认证）

Brand identification: Priority should be given to using 304 austenitic stainless steel (containing 8% nickel), which has been preliminarily verified through magnetic testing (weak magnetic or non-magnetic). The supplier is required to provide a material testing report (such as SGS certification)

厚度控制：门套 / 窗套包口建议≥1.2mm，台面收边≥0.8mm，潮湿区域（如卫生间）需加厚至 1.5mm

Thickness control: It is recommended that the door/window cover cover should be ≥ 1.2mm, the countertop edge should be ≥ 0.8mm, and the damp area (such as the bathroom) should be thickened to 1.5mm

耐候性适配：针对皖南潮湿气候，可定制 316L 不锈钢（含钼元素），盐雾测试需达到 1000 小时以上

Weather resistance adaptation: For the humid climate in southern Anhui, 316L stainless steel (containing molybdenum element) can be customized, and the salt spray test needs to reach more than 1000 hours

二、工艺标准

2、 Process standards

焊接工艺：采用激光焊接技术，焊缝均匀无气孔，现场可通过强光手电侧照检查

Welding process: Laser welding technology is used, and the weld seam is uniform without pores. It can be inspected on site by strong light flashlight side illumination

表面处理：

Surface treatment:

拉丝工艺（HL）：适合易脏区域，耐刮擦

Wire drawing process (HL): suitable for easily dirty areas, scratch resistant

镜面抛光（8K）：需确认是否做防指纹处理

Mirror polishing (8K): need to confirm whether anti fingerprint treatment is done

仿古做旧：需考察涂层附着力，可现场用 3M 胶带测试

Antique and antique style: coating adhesion needs to be examined, which can be tested on-site with 3M tape

折弯精度：内角 R 角≤2mm，对角线误差≤0.5mm，可携带直角尺现场测量

Bending accuracy: Inner angle R angle ≤ 2mm, diagonal error ≤ 0.5mm, can be measured on-site with a right angle ruler

三、适配性考量

3、 Adaptation considerations

模数匹配：适配安徽常用门窗规格（如 108 断桥铝），包口宽度建议 6-8cm，特殊尺寸需定制

Modular matching: Suitable for commonly used door and window specifications in Anhui (such as 108 broken bridge aluminum), recommended package width of 6-8cm, special sizes need to be customized

安装方式：

Installation method:

预埋式：需在泥瓦阶段预留 5mm 安装槽

Pre embedded: 5mm installation groove needs to be reserved during the mud tile stage

明装式：检查膨胀螺丝间距（≤30cm）及防锈处理

Surface mounted: Check the spacing between expansion screws (≤ 30cm) and rust prevention treatment

排水设计：阳台等露天区域需设置 3° 排水坡度，包口底部做滴水线处理

Drainage design: Balconies and other outdoor areas need to have a drainage slope of 3 °, and the bottom of the package should be treated with drip lines

四、本地化服务

4、 Localized services

售后响应：选择合肥、芜湖等产业集群地企业，要求 48 小时内上门维修

After sales response: Select enterprises in industrial clusters such as Hefei and Wuhu, and require on-site maintenance within 48 hours

案例验证：考察本地工程案例（如滨湖新区安置房项目），观察 2 年以上使用效果

Case verification: Investigate local engineering cases (such as the Binhu New Area resettlement housing project) and observe their usage effects for more than 2 years

价格体系：当前安徽市场价：拉丝款 180-220 元 / 米，镜面款 280-350 元 / 米，含安装费

Price system: Current Anhui market price: brushed version 180-220 yuan/meter, mirror version 280-350 yuan/meter, including installation fee
