滨州的住宅项目和写字楼项目有个共同特点：精装交付比例越来越高。电梯口两侧的瓷砖已经贴好了，门套才进场安装。这个顺序颠倒过来，麻烦就来了——瓷砖贴得不平整、左右不对称、洞口尺寸比设计值宽出几公分，常规门套装上去要么缝隙太大，要么压不住瓷砖边。

The residential and office projects in Binzhou have a common feature: the proportion of high-end decoration delivery is increasing. The tiles on both sides of the elevator entrance have been pasted, and the door frame has only been installed upon entering the site. The order is reversed, and trouble arises - the tiles are not evenly laid, not symmetrical, and the opening size is several centimeters wider than the design value. Conventional door sets either have too large gaps or cannot press the edges of the tiles.

已施工瓷砖的洞口，尺寸往往和图纸对不上。

The size of the holes in the constructed tiles often does not match the drawings.

瓦工贴砖时受基层平整度、瓷砖厚度、留缝宽度影响，电梯口的实际净尺寸和图纸偏差一两公分是常事。更麻烦的是左右不对称——一边贴了5公分，另一边贴了8公分，门套如果按标准尺寸做，装上去一边紧密贴合，另一边露出基层。滨州不少改造项目和老盘翻新都会遇到这个问题。

When tiling, it is common for the actual net size of the elevator shaft to deviate by one or two centimeters from the drawing due to factors such as the flatness of the base layer, the thickness of the tiles, and the width of the gaps left. What's even more troublesome is the asymmetry between the left and right sides - one side is pasted with 5 centimeters, and the other side is pasted with 8 centimeters. If the door frame is made according to the standard size, it fits tightly on one side and exposes the base layer on the other side. Many renovation projects and old buildings in Binzhou will encounter this problem.

针对这种情况，门套需要可调节的安装结构。诚耐金属的装配式电梯门套配备了专用安装配件，针对已施工瓷砖、左右不对称、距离过宽等工况，通过调整配件位置来补偿洞口偏差。门套的覆盖边宽度也要留有余量，15公分的造型能盖住大部分瓷砖边，避免露出毛边。

In response to this situation, the door frame requires an adjustable installation structure. Chengnai Metal's prefabricated elevator door frame is equipped with specialized installation accessories, which compensate for the deviation of the opening by adjusting the position of the accessories for working conditions such as already installed tiles, left-right asymmetry, and excessive distance. The width of the cover edge of the door frame should also have a margin, and a 15cm shape can cover most of the tile edges to avoid exposing burrs.

装配式安装和传统打底，差别在防火和工期。

The difference between prefabricated installation and traditional base installation lies in fire prevention and construction period.

传统门套安装用木龙骨或木工板打底，外面再包不锈钢。这种做法有两个隐患：一是木材不防火，高层建筑的电梯口属于疏散通道，消防验收对材料燃烧等级有要求；二是木龙骨受潮后变形，门套跟着歪。装配式门套淘汰了木龙骨和木工板，改用专用防火木塑纤维板做基层，防火性能更高，不易腐化，现场直接拼装，不需要等待打底干燥。滨州的一些精装项目反馈，装配式安装能有效缩短工期，而且施工现场没有木工板切割的粉尘污染。

Traditional door frames are installed with wooden keel or wooden board as the base, and then wrapped with stainless steel on the outside. There are two hidden dangers to this approach: firstly, wood is not fire-resistant, and elevator entrances in high-rise buildings are evacuation routes, so fire safety inspections have requirements for material combustion levels; The second reason is that the wooden keel deforms after being damp, and the door frame follows suit. Prefabricated door frames have replaced wooden keels and wooden boards with specialized fire-resistant wood plastic fiberboard as the base layer, which has higher fire resistance and is not easily corroded. They can be assembled directly on site without waiting for the base to dry. Feedback from some high-end decoration projects in Binzhou shows that prefabricated installation can effectively shorten the construction period, and there is no dust pollution from cutting wooden boards on the construction site.

表面耐磨处理，决定门套用几年还像新的。

The surface wear-resistant treatment determines that the door frame will still look like new after several years of use.

不锈钢门套的表面处理通常是拉丝或镜面。拉丝面耐磨但容易留下划痕，镜面好看但指纹和污渍明显。电梯口是人流量非常大的位置，推车、行李箱、装修材料进出都可能磕碰。诚耐金属的做法是在表面增加耐磨涂层，保护金属花纹，延长使用寿命。选购时可以问清楚表面处理工艺和耐磨层的具体做法。

The surface treatment of stainless steel door frames is usually brushed or mirrored. The brushed surface is wear-resistant but prone to scratches, while the mirror surface looks good but has obvious fingerprints and stains. The elevator entrance is the location with the highest flow of people, and carts, suitcases, and decoration materials entering and exiting may collide. The approach of Chengnai Metal is to add wear-resistant coatings on the surface to protect the metal patterns and extend their service life. When making a purchase, you can inquire about the specific surface treatment process and wear-resistant layer.

滨州项目的选型建议： 先确认电梯口瓷砖是否已施工，已施工的选带可调节配件的装配式门套；确认洞口左右是否对称，偏差大的需要定制覆盖边宽度；确认消防要求，疏散通道附近的门套基层建议用防火材料；确认售后承诺，安装质量影响长期使用，3年维修服务比低价更有价值。

Suggestions for the selection of Binzhou project: First confirm whether the elevator entrance tiles have been constructed, and for those that have been constructed, choose prefabricated door frames with adjustable accessories; Confirm if the left and right sides of the opening are symmetrical, and if there is a large deviation, customize the width of the covering edge; Confirm fire safety requirements, and fireproof materials must be used for the base layer of door frames near evacuation routes; Confirm after-sales commitment, installation quality affects long-term use, and 3-year maintenance service is more valuable than low price.
