铝合金卷帘门实现低价主要依赖以下三种方式：

The realization of low prices for aluminum alloy rolling shutter doors mainly relies on the following three ways:

规模化生产：通过批量生产摊薄单位成本；

Scale production: diluting unit costs through mass production;

原材料控制：采用低成本型材和配件；

Raw material control: using low-cost profiles and accessories;

管理优化：压缩人工、仓储等运营费用。

Management optimization: Reduce operating costs such as labor and warehousing.

对于小型作坊式生产者而言，虽然无法实现真正的规模化生产，但仍可通过以下方式压低：

For small-scale producers, although true scale production cannot be achieved, prices can still be lowered through the following methods:

采购低价型材进行简单加工组装

Purchase low-priced profiles for simple processing and assembly

使用非标或回收铝材（如废铝替代原生铝）

Using non-standard or recycled aluminum materials (such as scrap aluminum replacing primary aluminum)

省去检测、研发等必要环节

Eliminate necessary steps such as testing and research and development

然而，这种低价背后隐藏着严重隐患：

However, behind this low price lies a serious hidden danger:

风险：劣质材料易导致门体变形、轨道脱落，已发生多起"卷帘门吃人"事故；

Safety risk: Poor quality materials can easily cause door deformation and track detachment, resulting in multiple incidents of "rolling shutter door cannibalism";

防盗缺陷：多数廉价产品仅配备2个锁点，且无报警装置，防盗性能形同虚设；

Anti theft defects: Most cheap products are only equipped with 2 locking points and do not have alarm devices, making anti-theft performance virtually non-existent;

使用成本：初期节省的费用很快会被频繁维修抵消，常见问题包括：

Cost of use: The initial cost savings will soon be offset by frequent repairs, and common issues include:

电机寿命不足正常产品的1/3

The lifespan of the motor is less than one-third of that of a normal product

导轨变形导致无法正常启闭

The deformation of the guide rail leads to the inability to open and close normally

表面涂层半年内出现褪色剥落

Surface coating fades and peels off within six months

特别需要警惕的是，市场上存在用废铝冒充6063铝合金的情况。这类材料：

It is particularly important to be vigilant that there are cases in the market where scrap aluminum is used to impersonate 6063 aluminum alloy. This type of material:

抗拉强度降低40%以上

Reduce tensile strength by more than 40%

耐腐蚀性不足正规产品的1/5

Corrosion resistance is less than 1/5 of regular products

使用寿命缩短2-3年（正规产品可达8-10年）

The service life is shortened to 2-3 years (regular products can reach 8-10 years)

建议消费者在选购时：

Consumers are advised to:

① 要求出具材质检测报告

① Request for Material Inspection Report

② 检查型材截面是否密实无气泡

② Check if the cross-section of the profile is dense and free of bubbles

③ 确认滑轨厚度≥1.5mm

③ Confirm that the thickness of the slide rail is ≥ 1.5mm

④ 优先选择配备四锁点+防撬结构的产品

④ Prioritize products equipped with four locking points and anti pry structure

真正的性价比=初始+使用年限+维护成本，而非单纯的购买。那些便宜30%却只能用1/3时间的"低价门"，终成本往往是产品的2-3倍

The true cost-effectiveness is the initial price+service life+maintenance cost, rather than just the purchase price. Those "low-priced doors" that are 30% cheaper but can only be used for one-third of the time often have a final cost 2-3 times that of high-quality products
