铁艺大门安装完成后，很多业主只是开关两下、看两眼外观就签字验收了。等到使用几个月后出现下沉、变形、异响、生锈等问题，再找厂家，对方一句“验收时你没提”就能把你堵回去。

After the installation of the wrought iron gate is completed, many homeowners only need to switch it on and off twice, take a look at the appearance, and then sign and accept it. After a few months of use, if there are problems such as sinking, deformation, abnormal noise, rusting, etc., then contact the manufacturer, and they can block you back with just one sentence: 'You didn't mention it during acceptance.'.

安装验收是铁艺大门品质的“最后一道关”。以下是7个必查项，一个都不能漏。

Installation acceptance is the 'last hurdle' for the quality of wrought iron gates. Here are 7 required items, none of which should be missed.

必查项一：垂直度与水平度。

Must check item one: verticality and levelness.

用水平尺和线坠检查门框的垂直度和水平度。垂直度偏差不应超过3mm/m，水平度偏差不应超过2mm/m。门框如果装歪了，门扇长期处于受力不均状态，合页会加速磨损，门扇会逐渐下沉，最终导致开关困难甚至拖地。

Use a spirit level and plumb line to check the verticality and levelness of the door frame. The vertical deviation should not exceed 3mm/m, and the horizontal deviation should not exceed 2mm/m. If the door frame is installed crooked, the door leaf will be subjected to uneven force for a long time, and the hinges will wear out faster. The door leaf will gradually sink, ultimately leading to difficulty in opening and closing or even dragging the floor.

必查项二：门扇开启灵活度。

Must check item 2: Door leaf opening flexibility.

反复开关门扇至少10次，检查是否存在卡顿、异响、晃动。正常状态下，门扇应开启顺畅、无杂音。关闭时应与门框贴合紧密，缝隙均匀且不超过5mm。如果开启时有“咯吱”声，说明合页安装不到位或缺少润滑；如果有明显晃动，说明铰链固定不牢。

Repeatedly open and close the door leaf at least 10 times, checking for any jamming, abnormal noise, or shaking. Under normal conditions, the door leaf should open smoothly and without any noise. When closed, it should fit tightly with the door frame, with even gaps not exceeding 5mm. If there is a "creaking" sound when opened, it indicates that the hinge is not installed properly or lacks lubrication; If there is obvious shaking, it indicates that the hinge is not firmly fixed.

必查项三：焊接点质量。

Must check item three: welding point quality.

逐一检查所有焊接点。优质焊接的标准是：焊缝饱满均匀、无气孔夹渣、无虚焊漏焊、焊点打磨光滑无毛刺。如果发现焊缝有裂纹、表面粗糙或有明显的焊接飞溅物，说明焊接工艺不过关。焊接点是铁艺大门受力最集中的部位，焊接质量不过关，后期可能从焊点处断裂。

Inspect all welding points one by one. The standard for high-quality welding is: the weld seam is full and uniform, without porosity or slag inclusion, without virtual welding or leakage, and the weld points are polished smooth without burrs. If cracks, rough surfaces, or obvious welding spatter are found in the weld seam, it indicates that the welding process is not up to standard. The welding point is the most concentrated part of the iron gate, and if the welding quality is not up to standard, it may break from the welding point in the later stage.

必查项四：表面涂层质量。

Must check item four: surface coating quality.

检查表面涂层是否均匀光滑、无流挂、无气泡、无色差。用手背轻触表面，感受是否有颗粒感或粗糙感。重点检查焊接处、边角、螺丝孔等易漏涂部位——这些地方如果涂层不到位，很快就会从这些位置开始生锈。涂层附着力可用“划格法”简单测试——用刀片在涂层表面划十字格，用胶带粘贴后撕下，如果涂层大面积脱落则不合格。

Check whether the surface coating is uniform, smooth, free of sagging, bubbles, and color difference. Lightly touch the surface with the back of your hand to feel for any grainy or rough texture. Focus on inspecting welding joints, corners, screw holes, and other areas that are prone to missed coating - if the coating is not in place, rust will quickly start from these areas. The adhesion of the coating can be simply tested using the "grid method" - using a blade to make a cross grid on the surface of the coating, sticking it with tape and tearing it off. If the coating falls off in a large area, it is not qualified.

必查项五：锁具与五金件。

Must check item five: Locks and hardware.

反复测试锁具的开启和关闭，确保锁舌伸缩顺畅、锁闭牢固无晃动。检查合页、拉手、插销等五金件的安装是否牢固，螺丝是否全部拧紧。合页的承重能力要与门扇重量匹配——重型大门至少使用3个合页，且合页厚度不低于3mm。

Repeatedly test the opening and closing of the lock to ensure smooth expansion and contraction of the lock tongue, secure locking without shaking. Check if the installation of hardware components such as hinges, handles, and pins is secure, and if all screws are tightened. The load-bearing capacity of hinges should match the weight of the door leaf - heavy-duty doors should use at least 3 hinges, and the hinge thickness should not be less than 3mm.

必查项六：密封与间隙。

Must check item six: sealing and clearance.

检查门扇与门框之间的间隙。顶部和两侧间隙应控制在3-5mm，底部间隙不超过10mm（考虑地面找平误差）。间隙过大，大门关闭后晃动空间大；间隙过小，热胀冷缩后可能卡死。如果设计了密封条，检查密封条是否完整粘贴、有无脱落。

Check the gap between the door leaf and the door frame. The gap between the top and sides should be controlled within 3-5mm, and the gap at the bottom should not exceed 10mm (considering ground leveling errors). The gap is too large, and there is a lot of room for shaking when the door is closed; The gap is too small, and it may get stuck after thermal expansion and contraction. If a sealing strip is designed, check whether the sealing strip is fully adhered and whether it has come off.

必查项七：固定件与预埋件。

Must check item seven: Fixed parts and embedded parts.

检查地脚螺栓、膨胀螺丝等固定件是否全部安装、紧固到位。预埋件与门框的连接是否牢靠。用手用力推拉门框，检查是否有松动感。固定不牢是导致大门下沉倾斜的主要原因之一。

Check if all anchor bolts, expansion screws, and other fixing components are installed and securely fastened in place. Is the connection between the embedded parts and the door frame secure. Push the door frame forcefully by hand and check for any looseness. One of the main reasons for the sinking and tilting of the gate is that it is not firmly fixed.

验收不合格怎么处理？ 验收合格后应要求厂家提供正式的验收确认单，注明验收结果和保修起始日期。建议在验收单中注明质保期内出现问题厂家无条件维修的条款，常见约定保修期1至3年。所有沟通和承诺尽量书面化，避免口头承诺难以追溯。

What should be done if the acceptance is not qualified? After passing the acceptance inspection, the manufacturer should be requested to provide a formal acceptance confirmation form, indicating the acceptance results and the start date of the warranty. It is recommended to indicate in the acceptance form the clause that the manufacturer will unconditionally repair any problems that occur during the warranty period, with a commonly agreed warranty period of 1 to 3 years. All communication and commitments should be written as much as possible to avoid verbal commitments being difficult to trace.
