Galvanized coil is a thin steel plate with Q235 as the base material dipped into a melted zinc groove, so that its surface is adhered to a layer of zinc. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously dipped in the melting zinc bath to make galvanized steel coil.
Rail steel is usually used for railway fixed on the sleeper, sleeper for ballast. It is fastened by rail support, fastener, rail press, track splint, elastic bar, railway spike and other railway accessories. The bottom of the track is the track bed, which provides elasticity and drainage function for the track. Rails can also be laid on bases made of concrete, or even embedded in concrete. In order to withstand the pressure, impact load and friction of train operation, it requires sufficient strength and certain toughness. Quality requirements are strict, in addition to the guarantee of its chemical composition, but also require the inspection of mechanical properties, drop weight test and acid leaching of low-power tissue.

Different concepts C-section steel is processed by hot coil plate cold bending, thin wall and light weight, excellent section performance, high strength, compared with the traditional channel steel, the same strength can save about 30% of the material. Channel steel is hot rolled production, directly supplied by the steel plant, and the thickness of the larger, the section shape of the groove shaped strip of steel.
