John Fairbankstainless steel strip with good quality and the Sales clerk service is very good.i like this company i hope can work with your again
FleuriauShipment speed is very fast, and the requirements can meet me. Salesman is very responsible.
Fierce Urchingood ,the galvanized steel coil quality is good and i donot see the broken on them.that is nice

Hot Dipped Galvanized Steel Coil ASTM A653 SGCC DX51D Q195 30-275g/M2
To create galvanized steel, cold rolled steel is submerged into a molten zinc bath, known as the hot-dip process (galvanization can also be achieved through continuous galvanizing). When the material is removed from the zinc bath and cooled a reaction to the oxygen in the air occurs. The reaction causes the zinc coating to become part of the steel creating the well-recognized spangled finish.
Galvanized Steel Coil gets coated in layers of zinc because rust won't attack this protective metal. The most external layer is all zinc, but successive layers are a mixture of zinc and iron, with an interior of pure steel. These multiple layers are responsible for the amazing property of the metal to withstand corrosion-inducing circumstances. Zinc also protects the steel by acting as a "sacrificial layer." If rust does take hold on the surface of Galvanized steel Coil, the zinc will get corroded first. This allows the zinc that is spread over the breach or scratch to prevent rust from reaching the steel. For countless outdoor, marine, or industrial applications, Galvanized steel Coil is an essential fabrication component.Galvanized coil, the thin steel plate immersed in the molten zinc bath, so that its surface adheres to a layer of zinc thin steel plate. At present, continuous galvanizing process is mainly used to produce galvanized steel sheet, which is made by continuously immersing coiled steel sheet in galvanized bath and alloying galvanized steel sheet. This kind of steel plate is also made by hot dipping method, but it is heated to about 500 C immediately after the trough is out to form zinc and iron alloy film. The galvanized coil has good adhesion and weldability of the coating.

Hot Dip Galvanized coil produced by JIN LAI,is coated with zinc using a continuous and controlled process. The tight metallurgical bond between the steel and coating takes place in a continuous galvanizing line. This process results in a material with the strength and formability of steel and with the corrosion protection provided by zinc. The zinc coating protects the base metal from external corrosive elements in two main ways, by acting as (1) a physical barrier and (2) a sacrificial anode.
