铁艺护栏看起来是“装饰件”，但在阳台、楼梯、空调位这些地方，它是实打实的安全构件。高度不够、间距过大、固定不牢，都可能出大事。

Iron railings may seem like decorative elements, but in places like balconies, stairs, and air conditioning units, they are solid safety components. Insufficient height, excessive spacing, and unstable fixation can all lead to major incidents.

阳台护栏的高度有硬性规定。 6层及以下建筑，护栏高度需高于1.05米；6层以上建筑，需高于1.1米。这个数字来自建筑规范，低于标准的护栏在验收时可能通不过。如果是自建房或老旧小区改造，尤其要核对高度是否达标。

There are strict regulations on the height of balcony guardrails. Buildings with 6 floors or less must have guardrails higher than 1.05 meters in height; Buildings with more than 6 floors must be higher than 1.1 meters. This number comes from building codes, and guardrails that are below the standard may not pass inspection. If it is a self built house or renovation of an old residential area, it is especially important to check whether the height meets the standards.

立柱间距决定整体稳定性。 建议立柱间距控制在1.5到2米之间。间距过大，护栏整体刚度下降，用力推搡时晃动明显；间距过小，浪费材料且影响通透性。对于有小孩的家庭，护栏的竖向杆件间距还要考虑安全因素，确保孩子的头部无法穿过。

The spacing between columns determines overall stability. It is recommended to control the spacing between columns between 1.5 and 2 meters. The spacing is too large, and the overall stiffness of the guardrail decreases, causing significant shaking when pushing and shoving forcefully; The spacing is too small, which wastes materials and affects permeability. For families with children, the vertical spacing of guardrails should also consider safety factors to ensure that the child's head cannot pass through.

表面处理决定能用多久。 铁艺护栏普遍采用热浸镀锌技术，防锈周期可达20-50年。但“镀锌”和“喷塑”是两回事——镀锌是防锈底子，喷塑是表面颜色。只有喷塑没有镀锌的护栏，在潮湿环境中很快会从内部生锈。检查时看焊口和弯折处，这些位置最容易暴露防锈处理的真实水平。

Surface treatment determines how long it can be used. Iron railings commonly use hot-dip galvanizing technology, with a rust prevention period of up to 20-50 years. But "galvanizing" and "spraying" are two different things - galvanizing is a rust proof base, and spraying is the surface color. Guardrails that are only spray painted but not galvanized will quickly rust from the inside in humid environments. When inspecting, look at the welds and bends, which are the most likely to expose the true level of rust prevention treatment.

风格选择要和建筑“说话”。 欧式古典风格适合铸铁护栏，花纹繁复；现代简约风格适合锻铁护栏，几何造型利落。中式庭院可融入云纹、回纹等传统纹样。护栏是建筑的“表情”，选对了提升气质，选错了格格不入。

Style selection should speak to the architecture. The European classical style is suitable for cast iron guardrails, with intricate patterns; The modern minimalist style is suitable for wrought iron guardrails, with sharp geometric shapes. Chinese style courtyards can incorporate traditional patterns such as cloud patterns and loop patterns. Guardrails are the "expression" of architecture. Choosing the right one enhances the temperament, choosing the wrong one is incompatible.

铁艺护栏的选购逻辑是“安全第一、美观第二”。高度、间距、固定方式达标了，再谈样式和颜色。顺序对了，才不出错。

The selection logic of wrought iron guardrails is "safety first, aesthetics second". Once the height, spacing, and fixing method meet the standards, we can discuss the style and color. The order is correct to avoid errors.
