电梯门套厂家良莠不齐——有的用非标薄板几个月就生锈，有的焊接打磨粗糙接缝明显，有的产能不稳定供货周期一拖再拖。选对厂家，这5个维度一个不能少。

The quality of elevator door frame manufacturers varies - some use non-standard thin plates that rust within a few months, some have rough welding and grinding with obvious joints, and some have unstable production capacity and delayed supply cycles. Choose the right manufacturer, and none of these 5 dimensions should be omitted.

维度一：板材等级与厚度——材质报告是“照妖镜”

Dimension 1: Board grade and thickness - the material report is a "magic mirror"

国标304不锈钢含镍量≥8%，201或430材质耐腐蚀性差一大截。厚度方面，家用0.8mm-1.0mm，商用及高人流场所1.2mm-1.5mm。要求厂家提供材质检测报告或现场测量厚度，很多低价厂家以薄充厚。

National standard 304 stainless steel has a nickel content of ≥ 8%, and 201 or 430 materials have poor corrosion resistance. In terms of thickness, it is 0.8mm-1.0mm for household use and 1.2mm-1.5mm for commercial and high-altitude flow fields. Manufacturers are required to provide material testing reports or on-site thickness measurements, and many low-priced manufacturers use thin to fill thickness.

电梯门套专用标准更严——材料厚度建议保证1.5mm（实际厚度不得小于1.38mm）。

The standard for elevator door frames is stricter - the material thickness must be guaranteed to be 1.5mm (the actual thickness must not be less than 1.38mm).

维度二：加工工艺——激光切割+数控折弯是标配

Dimension 2: Processing technology - laser cutting+CNC bending is standard equipment

激光切割精度可达±0.1mm，数控折弯角度误差±0.5°。手工打磨的门套容易出现波浪纹，而自动化的焊接打磨能保证平整度。表面处理方面，要求厂家提供盐雾测试数据——国标要求不锈钢表面经72小时盐雾测试后无锈点。

The laser cutting accuracy can reach ± 0.1mm, and the CNC bending angle error is ± 0.5 °. Hand polished door frames are prone to wavy patterns, while automated welding and polishing can ensure flatness. In terms of surface treatment, manufacturers are required to provide salt spray test data - the national standard requires stainless steel surfaces to have no rust spots after 72 hours of salt spray testing.

维度三：生产规模与定制能力——日出货量和原料库存是关键指标

Dimension Three: Production Scale and Customization Capability - Daily Production Volume and Raw Material Inventory are Key Indicators

规模化厂家拥有自动化生产线，能快速调整模具参数，支持小批量定制与大批量订单并行。考察日出货量（如日产500套以上）和原料库存（常备国标板材现货）。

Large scale manufacturers have automated production lines that can quickly adjust mold parameters and support parallel small batch customization and large batch orders. Assess the daily production volume (such as over 500 sets per day) and raw material inventory (regularly stocked with national standard boards).

维度四：安装工艺——门头横料建议用竖料收口

Dimension four: Installation process - the horizontal material of the door head must be closed with vertical material

这是专业和业余的分水岭：门头横料建议用竖料来收口；制作基层要小于门套包边尺寸5mm左右，保证安装和打胶空间；门头板宽度略小于竖料宽度1-2毫米。能做到这几条的厂家，至少是有经验的。

This is the watershed between professional and amateur: the horizontal material at the entrance must be closed with vertical material; The base layer should be about 5mm smaller than the edge size of the door frame to ensure installation and adhesive space; The width of the door panel is slightly smaller than the width of the vertical material by 1-2 millimeters. The manufacturers who can achieve these are at least experienced.

维度五：行业口碑与案例——近三年批量工程是硬通货

Dimension 5: Industry reputation and cases - Batch engineering has been a hard currency in the past three years

查厂家近三年参与过的批量工程（住宅小区、写字楼、医院、学校等），了解交货准时率、返修率。专注电梯门套超过5年的企业，品控体系相对成熟。

Check the batch projects (residential communities, office buildings, hospitals, schools, etc.) that the manufacturer has participated in in in the past three years to understand the on-time delivery rate and repair rate. A company that has been focusing on elevator door frames for over 5 years, with a relatively mature quality control system.
