Hot-dipped galvanized C beams are made by dipping in liquid zinc based on black carbon steel C channels. Then the C beams are with a heavy zinc coating which can prevent the C channel from becoming rusty. The length is usually is 5.8 meters and 6 meters for option. The zinc coating for the hot dipped galvanized C channel is usually 140g/m2-600g/m2 and the zinc coating thickness is 20microns-120 microns.

Hot-dipped galvanized C channel is an effective way of preventing metal get corrosion. Hot dipped galvanized c channel is mainly used for metal structure industry facilities. Hot dip galvanized C channel according to the different can be divided into hot dip galvanizing technology on zinc steel channel and hot galvanized C channel is after cleaning of steel in 440 ~ 460 ℃ melting liquid zinc and the zinc layer adhered on the surface of the steel members, which have the purpose of corrosion protection.
Now the surface of the C channel steel galvanized mainly USES the method is hot dip galvanized. Hot dip galvanized is developed by older hot plating method. French apply hot galvanizing industry since 1836, has a history of 170 years. For nearly 30 years, however hot dipped galvanized C channel is with the rapid development of cold rolled steel strip, hot dip galvanized c channel industrial large-scale development.
Among various kinds of plating way to protect the steel substrate, hot-dip zinc is a very good one. It is under the conditions of zinc liquid, after a fairly complex physical and chemical action, not only on the plating on steel thicker pure zinc layer, but also produce a zinc-iron alloy layer. This kind of plating method, not only have the corrosion characteristics of electricity galvanized, and because of the zinc alloy layer. Also has is unable to compare to the galvanized strong corrosion resistance. So the plating method is especially suitable for all kinds of acid, alkali corrosive environments, such as the fog.
Packing method for hot dipped galvanized C channel is standard seaworthy export packing such as in bundled with firm steel straps, easy for loading and unloading. As for other types of packing can be customized as every requirement.
