Hot-dip galvanized cable trays are cleaned in a槽 containing an ammonium chloride or zinc chloride aqueous solution, or a mixture of both, and then immersed in molten zinc at approximately 500°C, resulting in a zinc layer of 30-50 micrometers on the black steel angle steel surface to achieve corrosion resistance. Hot-dip galvanized cable trays are commonly used in curtain walls, building steel structures, power towers, railway and highway protection, ship components, substation auxiliary facilities, and light industry, etc.

Section II: Manufacturing Process of Galvanized Bridge Channels

(1) Material Selection: Hot-dip galvanized steel sheet is used, cut to the length required by the customer and flattened. For bridge supports, which are designed for ease of access by building elevators or for convenient transportation, the standard length is typically 2 or 3 meters per piece. In some steel frame projects without support or hoisting points, bridge connections are often reduced to increase the strength of the bridge, which we refer to as long-span bridge supports. The length varies depending on the distance between support points, usually 6 meters, 9 meters, 12 meters, and so on.

(2) Cutting: Cut the sheet materials to the specified width according to the bridge frame槽体 body and cover plate specifications and thickness.

(3) Pressing: Each bridge rail end requires pressing to create holes for rail connections.

(4) Forming: Bending forming, Rolling forming
