工程采购里，电梯门套常被归到“小项”，等瓷砖贴完、门套装上，缝隙歪、边角锈、已贴砖的电梯口左右不对称，才知道它直接决定电梯厅的“第一眼档次”和后期维修费。

In engineering procurement, elevator door frames are often classified as "minor items". It is only after the ceramic tiles are pasted and the door frames are installed that the gaps, rust on the edges, and asymmetry of the already tiled elevator shaft are found to directly determine the "first glance grade" and later maintenance costs of the elevator hall.

先按场景定材质：

First, determine the material according to the scene:

不锈钢门套：商用楼宇、写字楼、医院优选，防火、防水、抗冲击，拉丝/镜面/古铜/玫瑰金大多能做；核心看板材牌号（304比201耐锈）、厚度（门套用0.8–1.2mm较稳）、折弯公差，差0.5mm拼缝就难看。

Stainless steel door frame: the preferred choice for commercial buildings, office buildings, and hospitals. It is fire-resistant, waterproof, and impact resistant, and can be made in brushed/mirrored/antique copper/rose gold; Focus on the plate grade (304 compared to 201 rust resistant), thickness (0.8-1.2mm is more stable for door frames), and bending tolerance. If there is a difference of 0.5mm, the joint will be unsightly.

大理石/石材门套：酒店大堂显贵，但重、易裂、运输和基层要求高，住宅公区现在用得少了。

Marble/stone door frames: The hotel lobby is expensive, but it is heavy, easy to crack, requires high transportation and base requirements, and is now used less in residential public areas.

铝合金门套：轻、不生锈、造价低，适合住宅批量精装；痛点是背层不打底、木工板受潮，装完容易翘边变形。

Aluminum alloy door frame: light, rust free, low cost, suitable for bulk decoration of residential buildings; The pain points are that the back layer is not bottom, the wooden board is damp, and it is easy to warp and deform after installation.

石塑/装饰线板：只做收边美化，不承撞，别拿来当电梯口主护角。

Stone plastic/decorative wire board: only used for edge beautification, not collision resistant, do not use it as the main protective corner of the elevator entrance.

潍坊、济南、临沂这类工地常踩的坑是：瓷砖先贴、门套后量。正确做法是门洞尺寸、墙厚、瓷砖完成面一起出图，用装配式门套（卡扣式/开槽式+防火木塑纤维板打底），不靠木龙骨，防潮又防火，装完不返工。

The common pitfalls on construction sites such as Weifang, Jinan, and Linyi are: tiling first, door frames measured later. The correct approach is to draw the door opening size, wall thickness, and ceramic tile finish together, using prefabricated door frames (snap fit/slotted+fireproof wood plastic fiber board as the base), without relying on wooden keel, moisture-proof and fireproof, and without rework after installation.

采购别只问“一套多少钱”，要问：是否按电梯口实测出图、板材厚度写不进合同、阳角是不是整料折弯、售后几年。门套是装配式建筑里非常像“细活”的构件——图省事，后面工人拿胶枪补缝，越补越丑。

Don't just ask "how much does one set cost" when purchasing, ask: whether the drawing is measured according to the actual elevator opening, whether the thickness of the board cannot be included in the contract, whether the corners are bent as a whole, and how many years of after-sales service. Door frames are the most delicate components in prefabricated buildings - designed to save time, with workers using glue guns to mend the seams at the back, making them look even uglier as they are repaired.
