很多老板觉得卷帘门就是一块铁皮往上一挂，谁便宜找谁做。结果用上半年就卡轨、异响、遥控器失灵，甚至扭簧断裂门帘直接砸下来。其实这门里藏着的门道，比门面装修还多。

Many bosses think that rolling shutter doors are just a piece of iron hanging up, and whoever is cheaper can find someone to make them. As a result, in the first half of the year, the track got stuck, there was abnormal noise, the remote control malfunctioned, and even the torsion spring broke and the door curtain fell down directly. In fact, there are more doorways hidden inside this door than just facade decoration.

先按场景选对类型：临街商铺要防盗和展示，彩钢或水晶帘片配防撬导轨；住宅车库别用工业厚板，选铝合金中空发泡+管状静音电机，半夜开关不扰邻；厂房仓库走货频繁，直接上抗风卷帘或PVC快速门，启闭速度0.6m/s起步；消防通道建议用带3C和烟温联动的防火卷帘，别拿普通门凑数，验收过不了。

First, select the right type according to the scene: street facing shops should be anti-theft and display oriented, with color steel or crystal curtains equipped with anti pry rails; Do not use industrial thick plates for residential garages, choose aluminum alloy hollow foam+tubular silent motor, and turn on and off at night without disturbing the neighbors; Frequent cargo flow in the factory warehouse requires direct access to wind resistant rolling shutters or PVC quick doors, with a starting speed of 0.6m/s for opening and closing; Fire exits must use fire-resistant rolling shutters with 3C and smoke temperature linkage. Do not use ordinary doors to make up for the number, as they will not pass the inspection.

再看三个非常容易偷工的地方：

Let's take a look at the three easiest places to steal work:

帘片厚度写进合同：商铺单层彩钢≥0.8mm，工业抗风款≥1.2mm，别信“加厚”口头承诺，让师傅带卡尺现场量裸板。

The thickness of the curtain should be included in the contract: the single-layer color steel of the shop should be ≥ 0.8mm, and the industrial wind resistant version should be ≥ 1.2mm. Don't believe the verbal promise of "thickening", let the master bring a caliper to measure the bare board on site.

电机和门体要匹配：小门用220V管状电机，宽大门洞换380V外挂电机，小马拉大车，电机一年就烧。

The motor and door body should be matched: a 220V tubular motor is used for the small door, a 380V external motor is replaced for the wide door opening, and a small horse pulls a large car. The motor burns out within a year.

导轨和扭簧别省：导轨垂直度每米偏差≤1.5mm，扭簧预紧力按门重调好。扭簧是平衡系统的“隐形心脏”，自己别乱拧，断簧下坠非常危险。

Save on guide rails and torsion springs: The deviation of guide rail verticality per meter is ≤ 1.5mm, and the pre tightening force of torsion springs should be adjusted according to the weight of the door. The torsion spring is the "invisible heart" of the balance system. Do not twist it randomly, as it is very dangerous for the spring to break and fall.

非常后提醒一句：空心砖墙、轻质隔墙不能直接打膨胀螺丝，建议做预埋件；报价问清是不是含测量、含电机、含售后，不然进场再加钱比门还贵。

Finally, a reminder: Hollow brick walls and lightweight partition walls cannot be directly screwed with expansion screws, and must be pre embedded with components; Please clarify whether the quotation includes measurement, motor, and after-sales service, otherwise the additional cost upon arrival is even more expensive than the door.
