选电梯门套，大多数人第一反应是比价格、看效果图。但有一个更底层的判断维度被忽略了：这个电梯口，谁在用它、怎么用它。 住宅电梯、写字楼电梯、商场货梯，使用场景不同，门套的选型逻辑完全不同。

When choosing an elevator door frame, most people's first reaction is to compare the price and look at the rendering. But there is a more fundamental dimension of judgment that has been overlooked: who is using this elevator entrance and how it is being used. Residential elevators, office building elevators, and shopping mall freight elevators have completely different selection logics for door frames depending on their usage scenarios.

住宅电梯门套：防撞是第一需求。 家用电梯口是搬运家具、拿重物进出的必经之地。不锈钢的抗撞击能力在这里是硬指标——根据《GB7588-2003》规定，电梯门套需在5cm×5cm范围内承受300N静力和1000N撞击力。石材虽然质感出彩，但脆性大，搬运大件时磕在尖角上可能崩边甚至开裂，一旦碎了很难巧妙修复。不锈钢磕碰后抛光即可修复，对住宅场景更友好。

Residential elevator door frame: collision prevention is the primary requirement. The entrance of a household elevator is a necessary passage for moving furniture and carrying heavy objects in and out. The impact resistance of stainless steel is a hard indicator here - according to GB7588-2003, elevator door frames need to withstand 300N static force and 1000N impact force within the range of 5cm × 5cm. Although stone has a high-quality texture, it is highly brittle. When handling large items, if it hits sharp corners, it may break edges or even crack. Once it is broken, it is difficult to repair it perfectly. Stainless steel can be repaired by polishing after being bumped, which is more friendly to residential scenes.

写字楼电梯门套：高频清洁场景。 写字楼电梯厅每天承受大量人流触摸，镜面不锈钢的“指纹收集器”属性在这里是减分项。哑光拉丝工艺因能有效遮蔽指纹且避免光污染，成为公共空间的优选，纹理方向应保持一致。如果选择镜面，清洁频次需要成倍增加。

Office building elevator door frame: high-frequency cleaning scenario. The elevator hall of an office building is subjected to a large number of people touching it every day, and the "fingerprint collector" attribute of the mirror stainless steel is a reduced item here. Matte brushed technology has become the preferred choice for public spaces due to its ability to effectively mask fingerprints and avoid light pollution, and the texture direction should be consistent. If choosing a mirror surface, the cleaning frequency needs to be doubled.

商场货梯门套：耐磨比美观重要。 货梯口频繁进出推车、货物，门套受到的碰撞远比客梯剧烈。不锈钢的耐磨性使其成为更务实的选择，板材厚度建议不低于1.5mm。

Shopping mall elevator door frame: Wear resistance is more important than aesthetics. The frequent entry and exit of carts and goods at the cargo elevator entrance results in much more severe collisions on the door frame than on passenger elevators. The wear resistance of stainless steel makes it a more practical choice, and the recommended plate thickness is not less than 1.5mm.

底部收边是所有场景的“共同软肋”。 门套挨着地面的那一圈非常容易受潮和被推车撞击。不锈钢门套的底口一定要收边严密，如果底部处理不到位，水汽会从缝隙渗入基层，加速锈蚀和变形。

The bottom edge is a common weakness for all scenes. The circle of the door frame next to the ground is most susceptible to moisture and being hit by carts. The bottom of the stainless steel door frame must be tightly closed. If the bottom is not properly treated, water vapor will seep into the base through the gaps, accelerating corrosion and deformation.

选门套的本质，是判断“这个位置每天承受什么”。住宅选耐撞的，写字楼选好清洁的，货梯选耐磨的。把使用场景想清楚了，材质答案自然浮现。

The essence of choosing a door frame is to determine 'what this position bears every day'. Choose durable residential buildings, clean office buildings, and wear-resistant freight elevators. After thinking clearly about the usage scenario, the material answer naturally emerged.
