What is DX51D Z40 galvanized steel coil?
The dx51d z40 galvanized steel coil is highly malleable and flexible and is utilized in cold roll forming with BS EN 10346:2015. Additionally, it is useful in drainage systems, window profiles, roofs, household appliances, road barriers, and bridges. On top of that, it is also used in agricultural equipment, including barns and granaries.
zinc content is at least 99%.

What does z40 mean?
Z40 is a coating designation that shows that the approximate coating thickness of both sides is 40g/m2.
Z40 galvanized steel coil is a low-weight zinc layer, which is only suitable for areas that do not require high corrosion resistance or do not require high durability. For example, galvanized corrugated sheets processed with Z40 galvanized steel coils can be used for about 3-5 years and will rust in 2 years in coastal areas. For the requirement of using more than 10 years, it is recommended to use Z275 galvanized steel coil.
- Product Process
1 The crane lifts the coil to the inlet saddle, and the roll-up trolley takes the steel coil from the saddle and sends it to the unwinder drum.
2 The uncoiler rotates, the unwinding knife swings, and the steel head enters the pinch straightening machine
3 The strip runs forward, and the upper roll and the next roll are sheared and welded on the narrow seam welder.
4 strip steel is sprayed by alkali solution, lye scrubbing, electrolytic degreasing, water scrubbing, spray cleaning and drying, then enters the inlet looper
5 strip steel through the correcting roller, steering roller, tension roller into the vertical reduction annealing furnace
6 The strip steel is heat treated in an annealing furnace and then enters the zinc pot along the nose of the furnace.
7 The strip steel is attached with a layer of zinc liquid from the surface of the zinc pot. The compressed air blown by the air knife blows off the excess zinc liquid to ensure uniform thickness of the zinc layer.
8 strip steel enters air cooling, and then enters water quenching tank to cool
9 Strip steel through the finishing machine, tension leveler, enter the chemical treatment section for passivation treatment (line 5 has fingerprint resistance)
10 The strip enters the export looper, and the loop is inspected and oiled into the coiler for winding. When the required coil weight is reached, the coil is divided.
11 The unloading trolley removes the steel coil from the coiler, and the crane lifts the steel coil to the finished product warehouse for packaging.
