铁艺大门，又称铁艺门、庭院门，是一种建筑装饰艺术，其初始功能以防盗为主，后逐步发展为兼具实用性与装饰性的多元化功能金属构件。在国内，铁艺大门主要应用于小区入口、别墅庭院入口、新农村、大型建筑外部入口、工厂大门等场所。作为建筑装饰艺术，铁艺大门出现在17世纪初期的巴洛克建筑风格盛行时期，一直伴随着欧洲建筑装饰艺术的发展。

Iron gate, also known as iron gate or courtyard gate, is a type of architectural decorative art. Its initial function was mainly anti-theft, and it gradually developed into a diversified functional metal component that combines practicality and decoration. In China, wrought iron gates are mainly used at entrances to residential areas, villa courtyards, new rural areas, external entrances to large buildings, factory gates, and other places. As an architectural decorative art, wrought iron gates appeared during the prevalence of Baroque architectural style in the early 17th century and have been accompanying the development of European architectural decorative art.

铁艺大门按工艺分两大类： 铁艺大门按工艺分为铸铁与锻打两类。锻打工艺采用专用铁艺材料，通过高温加热后手工锻打成型，纹理自然流畅，每一件作品都具有独特性。铸铁大门则是将铁水浇入模具成型，适合批量生产，成本相对较低但艺术表现力不如锻打。

Iron gates are divided into two categories based on their craftsmanship: cast iron gates and forged gates. The forging process uses specialized iron materials, which are manually forged and formed through high-temperature heating. The texture is natural and smooth, and each piece has its own unique characteristics. Cast iron gates are formed by pouring molten iron into molds, which are suitable for mass production and have relatively low costs, but their artistic expression is not as good as forging.

按风格划分： 从风格上可分为古典型和现代型。古典型多采用复杂图案、仿古色调并展现粗犷艺术风格；现代型以简洁方管结构为主。别墅铁艺大门还衍生出传统吉祥中国风、欧洲奢华等细分类型。

Divided by style: It can be divided into classical and modern styles. Classical styles often use complex patterns, antique color tones, and showcase rough artistic styles; The modern model mainly features a simple square tube structure. The villa's wrought iron gate has also spawned traditional auspicious Chinese style, European luxury and other sub types.

按结构划分： 分为栏杆通透型与实心门扇型。前者以方管框架镶嵌铁艺配件，通透感强、采光好；后者以铁板为基底结合装饰配件，私密性和防盗性更优。

Divided by structure: divided into railing transparent type and solid door leaf type. The former is embedded with iron fittings in a square tube frame, which has strong transparency and good lighting; The latter is based on iron plates combined with decorative accessories, providing better privacy and anti-theft performance.

按开启方式划分： 主要有平开和推拉两种。平开大门分为4种类型，每种类型包括900～8400mm共12种门洞宽度、1500～3000mm共6种门扇标志高度，共72种门型供设计选用。平开门适合跨度≤4m的场合，开启角度≥90°；推拉门适合跨度＞4m的大门。

Divided by opening method: there are mainly two types: flat opening and push-pull. There are 4 types of swing doors, each including 12 door opening widths ranging from 900mm to 8400mm, 6 door leaf sign heights ranging from 1500mm to 3000mm, and a total of 72 door types for design selection. Flat doors are suitable for situations with a span of ≤ 4m and an opening angle of ≥ 90 °; Sliding doors are suitable for large doors with a span greater than 4m.

选材是铁艺大门的核心： 钢材的质量直接决定大门的坚固程度和使用寿命。大门主框架钢材厚度应不小于3mm。常见钢材有普通碳素钢和不锈钢——普通碳素钢价格相对较低，但防锈性能较差，需进行严格的防锈处理；不锈钢具有优异的防锈、耐腐蚀性能，适用于沿海地区或潮湿环境，但成本较高。优先选用Q235/Q345碳素结构钢（厚度≥3mm），钢材需满足《碳素结构钢》（GB/T700）要求，表面无裂纹、夹渣等缺陷。

Material selection is the core of wrought iron gates: the quality of steel directly determines the strength and service life of the gate. The thickness of the main frame steel for the gate should not be less than 3mm. Common steels include ordinary carbon steel and stainless steel - ordinary carbon steel has a relatively low price, but its rust prevention performance is poor and requires strict rust prevention treatment; Stainless steel has excellent rust and corrosion resistance, suitable for coastal areas or humid environments, but the cost is relatively high. Priority should be given to using Q235/Q345 carbon structural steel (thickness ≥ 3mm), which must meet the requirements of "Carbon Structural Steel" (GB/T700) and have no defects such as cracks or slag inclusions on the surface.

配件同样关键： 合页作为连接大门与门框的关键部件，应选择承重能力强、材质厚实的合页，建议采用不锈钢或铸铁材质。门锁和拉手不仅要实用，还要与大门整体风格相协调，选择经过防锈处理、机械性能良好的产品。锁具、合页、把手建议选用304不锈钢或铜合金，避免电化学腐蚀。

Accessories are equally crucial: hinges, as key components connecting doors and door frames, should be selected with strong load-bearing capacity and thick materials. It is recommended to use stainless steel or cast iron materials. Door locks and handles should not only be practical, but also coordinated with the overall style of the door. Choose products that have undergone rust prevention treatment and have good mechanical performance. It is recommended to use 304 stainless steel or copper alloy for locks, hinges, and handles to avoid electrochemical corrosion.

防锈处理是铁艺大门的“生命线”： 铁艺大门最有效、最实用的防锈方法是热浸镀锌。热浸镀锌是将铁艺大门浸入熔化的锌中，在表面生成锌铁合金层及纯锌层，用以隔绝铁艺工件被氧化的机会，防锈期长达20-50年以上。镀锌层厚度应≥85μm。面层可选用氟碳漆、丙烯酸聚氨酯漆（耐候性≥10年）。沿海地区强烈建议选择316不锈钢材质或热镀锌+氟碳漆双重防护，抵抗氯离子腐蚀。

Rust prevention treatment is the "lifeline" of wrought iron gates: the most effective and practical rust prevention method for wrought iron gates is hot-dip galvanizing. Hot dip galvanizing is the process of immersing a wrought iron gate in molten zinc to form a zinc iron alloy layer and a pure zinc layer on the surface, which is used to isolate the opportunity for the wrought iron workpiece to be oxidized. The rust prevention period can last for more than 20-50 years. The thickness of the galvanized layer should be ≥ 85 μ m. The surface layer can be coated with fluorocarbon paint or acrylic polyurethane paint (weather resistance ≥ 10 years). It is strongly recommended to choose 316 stainless steel material or hot-dip galvanized+fluorocarbon paint for dual protection in coastal areas to resist chloride ion corrosion.
