Hot dip galvanized H-shaped steel is a process that forms a uniform zinc iron alloy layer on the surface of H-shaped steel after multiple processes such as acid pickling. It has the characteristics of corrosion resistance, good durability, high strength, good toughness, and good seismic performance. Its external dimensions are standardized and can meet various specifications. It has low density, light weight, and is easy to transport and install.

塑性強是熱浸鋅H型鋼的主要特點之一，其強度高、韌性好、抗震性好，比普通鋼材更具實用性。

Strong plasticity is one of the main characteristics of hot-dip galvanized H-beam steel, which has high strength, good toughness, and seismic resistance, making it more practical than ordinary steel.

在表面保護方面，熱浸鋅技術是H型鋼的核心特點。熱浸鋅工藝可以防止氧化和耐腐蝕，從而保障了鋼材的使用壽命，減少了維護和更換成本。

In terms of surface protection, hot-dip galvanizing technology is the core feature of H-beam steel. The hot dip galvanizing process can prevent oxidation and corrosion, thereby ensuring the service life of the steel and reducing maintenance and replacement costs.

二、應用領域

2、 Application field

熱浸鋅H型鋼廣泛應用于建筑、鋼結構工程和道路橋梁等領域。在建筑領域，它可用于建設高層建筑、大橋、地下站等；在鋼結構工程方面，可用于制造工業廠房、接觸網桿等；在道路橋梁方面，熱浸鋅H型鋼被廣泛用于橋梁結構中的梁、橋墩、橋臺等。

Hot dip galvanized H-shaped steel is widely used in fields such as architecture, steel structure engineering, and roads and bridges. In the field of architecture, it can be used to construct high-rise buildings, bridges, underground stations, etc; In terms of steel structure engineering, it can be used for manufacturing industrial factories, overhead contact system poles, etc; In terms of roads and bridges, hot-dip galvanized H-beams are widely used in bridge structures such as beams, piers, and abutments.

特別是在海洋環境和潮濕環境下，熱浸鋅H型鋼能夠保障鋼材的安全和耐用性，這讓其成為海洋工程中的首選材料。

Especially in marine and humid environments, hot-dip galvanized H-beams can ensure the safety and durability of steel, making them the preferred material in marine engineering.

三、優勢

3、 Advantages

與普通的鋼材相比，熱浸鋅H型鋼的優勢主要體現在幾個方面：耐腐蝕、性能持久、安全性高、施工簡單、易于維修和更換等，而這些優勢也成為了其在建筑和基礎設施工程中得到廣泛應用的原因。

Compared with ordinary steel, the advantages of hot-dip galvanized H-shaped steel are mainly reflected in several aspects: corrosion resistance, long-lasting performance, high safety, simple construction, easy maintenance and replacement, etc. These advantages have also become the reasons for its widespread application in construction and infrastructure engineering.

熱浸鋅H型鋼的價格主要受制造成本和市場需求的影響。  產規格和尺寸不同，熱浸鋅H型鋼重量和價格也會有所不同。熱浸鋅H型鋼（150*75*5*7）的重量為17.9公斤/米，每米的價格約為136元。而熱浸鋅H型鋼（200*100*5.5*8）的重量為31.5公斤/米，每米的價格約為225元。

The price of hot-dip galvanized H-beam is mainly influenced by manufacturing costs and market demand. The weight and price of hot-dip galvanized H-beams may vary depending on the production specifications and dimensions. The weight of hot-dip galvanized H-shaped steel (150 * 75 * 5 * 7) is 17.9 kilograms per meter, with a price of approximately 136 yuan per meter. The weight of hot-dip galvanized H-beam (200 * 100 * 5.5 * 8) is 31.5 kilograms per meter, with a price of approximately 225 yuan per meter.
