鍍鋅橋架板材有哪些分類

        云南橋架廠分為普通鍍鋅橋架、熱浸鋅橋架、合金化鍍鋅鋼板橋架等，根據(jù)不同的場合使用不同的板材。

        云南熱浸鍍鋅橋架鋼板。將薄鋼板浸入熔解的鋅槽中，使其外表粘附一層鋅的薄鋼板。目前次要采用延續(xù)鍍鋅工藝消費(fèi)，即把成卷的鋼板延續(xù)浸在熔解有鋅的鍍槽中制成鍍鋅鋼板;

　　云南合金化鍍鋅橋架鋼板。這種鋼板也是用熱浸法制造，但在出槽后，立刻把它加熱到500℃左右，使其生成鋅和鐵的合金薄膜。這種鍍鋅板具有良好的涂料的密著性和焊接性;

       云南電鍍鋅橋架鋼板。用電鍍法制造這種鍍鋅鋼板具有良好的加工性。但鍍層較薄，耐腐蝕性不如熱浸法鍍鋅板;

      云南單面鍍和雙面差鍍鋅橋架鋼板。單面鍍鋅鋼板，即只在一面鍍鋅的產(chǎn)品。在焊接、涂裝、防銹處置、加工等方面，具有比雙面鍍鋅板更好的適應(yīng)性。為克制單面未涂鋅的缺陷，又有一種在另面涂以薄層鋅的鍍鋅板，即雙面差鍍鋅板;

Yunnan bridge plant is divided into ordinary galvanized bridge frame, hot dip zinc bridge frame, alloyed galvanized steel bridge frame, according to different occasions to use different plates.

Yunnan hot dip galvanized bridge steel plate. The sheet is immersed in a molten zinc tank to externally adhere to a sheet of zinc. At present, the secondary use of continued galvanized process consumption, that is, the coil of steel continued immersion in the melting of zinc plating bath made of galvanized steel;

Yunnan alloyed galvanized bridge frame steel plate. This steel plate is also made by hot dip method, but after the tank, it is immediately heated to about 500℃, so that it produces zinc and iron alloy film. This galvanized sheet has good coating tightness and weldability;

Yunnan Electric galvanized bridge frame steel plate. There is good processability in making this galvanized steel sheet by electroplating. But the coating is thinner, corrosion resistance than hot dip galvanized sheet;

Yunnan single - sided and double - sided galvanized bridge steel plate. A single galvanized steel sheet is a product that is galvanized on only one side. In welding, painting, rust treatment, processing and other aspects, has better adaptability than double galvanized sheet. In order to control the defect of uncoated zinc on one side, there is another galvanized sheet coated with thin layer of zinc on the other side, namely two-sided differential galvanized sheet;
