济南很多老板打电话第一句就问"多少钱一平"，可卷帘门真不是按平米随便挂的铁皮。装完才发现门楣空间不够、导轨蹭墙、电机带不动——返工一次比买门还贵。

Many bosses in Jinan ask "how much does it cost per square meter" when they first call, but rolling shutter doors are not just iron sheets hanging randomly by square meter. After installation, it was discovered that there was not enough space for the lintel, the guide rail was rubbing against the wall, and the motor couldn't be moved - reworking it once was even more expensive than buying a door.

先量后选，顺序不能反

Measure first, select later, the order cannot be reversed

门洞量错一厘米，门体升降就卡顿。净宽取上中下非常小值，净高取左中右非常小值，顶留卷轴箱400–600mm，两侧各留100–250mm导轨位，地面高差超10mm先找平。轻质隔墙建议加钢立柱，别靠单钉吃力。

The measurement of the door opening is one centimeter wrong, causing the door to stall when lifted or lowered. Take the minimum value of the top, middle, and bottom for the net width, and the minimum value of the left, middle, and right for the net height. Leave a scroll box of 400-600mm at the top and 100-250mm guide rails on both sides. If the ground height difference exceeds 10mm, level it first. Lightweight partition walls must be equipped with steel columns, and do not rely on single nails to make it difficult.

按场景定类型

Type by Scene

临街商铺：双层中空铝合金电动卷帘，遥控高频开关，保温隔音；

Street facing shops: double-layer hollow aluminum alloy electric roller blinds, remote control high-frequency switch, thermal insulation and sound insulation;

车库：带遇阻反弹+断电手动离合，安全配置不能省；

Garage: Equipped with resistance rebound and power-off manual clutch, safety configuration cannot be omitted;

厂房仓库：抗风卷帘，帘片加强筋，抗风压≥600Pa；

Factory warehouse: wind resistant roller shutter, reinforced ribs on the curtain, wind pressure resistance ≥ 600Pa;

消防分区：防火卷帘（钢质/无机布），配3C认证、烟温联动，普通快速门不能替。

Fire zone: Fireproof roller shutter (steel/inorganic cloth), equipped with 3C certification, smoke and temperature linkage, cannot be replaced by ordinary quick doors.

硬参数写进合同

Write hard parameters into the contract

帘片彩钢≥0.8mm、双层铝≥1.0–1.2mm；导轨冷轧钢≥1.5mm；4m内220V管状电机800–1000W，大跨度上380V三相，带过热保护和手动释放。别信口头"加厚"，到货卡尺抽检。

Curtain color steel ≥ 0.8mm, double-layer aluminum ≥ 1.0-1.2mm; guide rail cold-rolled steel ≥ 1.5mm; 220V tubular motor 800-1000W within 4m, 380V three-phase over large span, with overheating protection and manual release. Don't believe in verbal "thickening", inspect with calipers upon arrival.

安装完当场测三件事

Three things to test on site after installation

升降无卡顿、遇阻自动回弹、断电手拉顺滑。后期每月清导轨灰尘、查链条张紧，别等门卡半空再硬拽。

Lifting without any lag, automatic rebound when encountering obstacles, smooth manual pulling when powered off. Clean the dust on the guide rail and check the tension of the chain every month in the later stage. Don't wait for the door card to be in mid air before forcefully pulling it.

找本地有实体厂、能复尺能打样的队伍，比电话里报低价、到货再增项稳得多。

Finding a local team with physical factories and the ability to replicate measurements and make samples is much more stable than quoting low prices over the phone and adding additional items upon arrival.
