很多济南业主挑院门，先问“有没有欧式花纹”“能不能做古铜色”，却忽略了一个事实：铁艺门在室外真正的敌人不是颜值过时，而是焊缝处悄悄爬出来的红锈。

Many homeowners in Jinan choose courtyard doors and ask if they have European patterns or if they can be made in antique bronze, but they overlook a fact: the real enemy of wrought iron doors outdoors is not outdated appearance, but the red rust that quietly crawls out of the welds.

选门先卡三个硬指标：

Choose three hard indicators first:

管材别信“标称厚”：庭院门主框实厚≥1.5mm，厂区宽门立柱做到2.0mm以上，拿卡尺量管口，别信销售嘴里的“加厚款”。

Don't trust the "nominal thickness" of the pipe material: the actual thickness of the main frame of the courtyard door should be ≥ 1.5mm, and the width of the door column in the factory area should be above 2.0mm. Use a caliper to measure the pipe mouth, and don't trust the "thickened version" in the sales mouth.

防锈看工艺链，不看广告语：只刷漆的门，济南冬夏温差一折腾，两年准起皮。正经做法是整件热浸镀锌（锌层≥80μm）+静电喷塑或氟碳面漆，焊口和切割断面也要补锌打磨，这一套做到位，户外用十年不成问题。

Rust prevention depends on the process chain, not on the advertising slogan: A door that is only painted will peel after two years of temperature difference between winter and summer in Jinan. The proper practice is to hot-dip galvanize the entire piece (zinc layer ≥ 80 μ m)+electrostatic spraying or fluorocarbon topcoat, and the welded joints and cutting sections should also be repaired with zinc polishing. This set is done properly and can be used outdoors for ten years without any problem.

安装基础别外包甩锅：门柱预埋深度≥50cm，底部混凝土墩夯实，门扇四周留10–20mm伸缩缝。很多门用半年下垂异响，根子都在地基没浇牢。

Installation of foundation outsourcing: The pre embedded depth of the door post should be ≥ 50cm, the bottom concrete pier should be compacted, and 10-20mm expansion joints should be left around the door leaf. Many doors have been hanging for half a year with abnormal noise, and the roots are not firmly poured on the foundation.

顺手再盯一眼五金：合页用304不锈钢或轴承地轴，锁体别配几十块的杂牌芯，电动门一定加遇阻回弹。这些小件坏了，整扇门就得跟着拆。

Take another glance at the hardware: the hinges are made of 304 stainless steel or bearing shafts, and the lock body is equipped with dozens of miscellaneous cores. The electric door must have rebound when encountering resistance. If these small items are broken, the entire door will have to be dismantled.

别光盯着效果图下单，让厂家把“材质、镀锌、漆膜厚度、质保几年”写进合同，比砍两百块钱单价实在得多。

Don't just focus on the renderings when placing an order, asking the manufacturer to include "material, galvanizing, paint film thickness, and warranty for several years" in the contract is much better than cutting the unit price by 200 yuan.
