鋁合金卷簾門實現低價主要依賴以下三種方式：

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

規模化生產：通過批量生產攤薄單位成本；

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;

管理優化：壓縮人工、倉儲等運營費用。

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

對于小型作坊式生產者而言，雖然無法實現真正的規模化生產，但仍可通過以下方式壓低：

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

采購低價型材進行簡單加工組裝

Purchase low-priced profiles for simple processing and assembly

使用非標或回收鋁材（如廢鋁替代原生鋁）

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

省去檢測、研發等必要環節

Eliminate necessary steps such as testing and research and development

然而，這種低價背后隱藏著嚴重隱患：

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

風險：劣質材料易導致門體變形、軌道脫落，已發生多起"卷簾門吃人"事故；

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

防盜缺陷：多數廉價產品僅配備2個鎖點，且無報警裝置，防盜性能形同虛設；

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：初期節省的費用很快會被頻繁維修抵消，常見問題包括：

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

電機壽命不足正常產品的1/3

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

導軌變形導致無法正常啟閉

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

表面涂層半年內出現褪色剝落

Surface coating fades and peels off within six months

特別需要警惕的是，市場上存在用廢鋁冒充6063鋁合金的情況。這類材料：

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:

抗拉強度降低40%以上

Reduce tensile strength by more than 40%

耐腐蝕性不足正規產品的1/5

Corrosion resistance is less than 1/5 of regular products

使用壽命縮短2-3年（正規產品可達8-10年）

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

建議消費者在選購時：

Consumers are advised to:

① 要求出具材質檢測報告

① Request for Material Inspection Report

② 檢查型材截面是否密實無氣泡

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

③ 確認滑軌厚度≥1.5mm

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

④ 優先選擇配備四鎖點+防撬結構的產品

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

真正的性價比=初始+使用年限+維護成本，而非單純的購買。那些便宜30%卻只能用1/3時間的"低價門"，終成本往往是產品的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
