1.  Pre-Painted Galvanized/Aluzinc Steel Coil--Chinese Best in Low Price

With GI as base material, after pretreatment (degrease and chemical treatment ) and liquid dope with several layers of color, then after firing and cooling, finally the plate steel is called pre-painted galvanized (aluzinc) steel. Pre-painted galvanized steel is good capable of decoration, molding, corrosion resistance. It generally displays superior workability, durability and weather resistance.

2.Main Features

• Excellent process capability

• Smooth and flat surface

• Workability, durability

• High strength

Q:Cold rolled steel coil steel, what is the difference?
Cold: hot rolled steel coil as raw material by pickling descaling after cold rolling, the finished rolling hard volumes, due to continuous deformation caused by cold hardening the volume rolling hard strength, hardness, toughness index rise decline, so the stamping performance will deteriorate, only for a simple deformation of parts. Rolled hard rolls can be used as raw material for hot galvanizing plants. Because the hot galvanizing units are equipped with annealing lines, the steel coils are rolled continuously at room temperature. Its strength is very high, but toughness, weldability is slightly worse, bright surface, not easy to corrosion, in order to prevent rust, the factory surface is coated with a protective layer of oil (hot rolling did not). Because of the complexity of the process, the price is higher.
Q:Measures to prevent cold rolling of packaged cold rolled steel coils? Who can give some professional opinions oh?
In order to prevent rusting in the process of storage or transportation of steel roll, steel mills generally take the following packing: inner gas antirust paper wrapped with tape wrapped in plastic film sealing, intermediate, involute cardboard seal lining, cardboard corner, with iron and steel outer package corner protector, strapping fixed. If the inner package seal, so the steel coil is sank into the water, will not rust out.
Q:Aluminum alloy rolling doors and color steel shutter door that good
Aluminum Alloy shutter door instead of the traditional rolling door noise inherent shortcoming, the process of opening and closing of windleavesthe sound {(Note: the design of Aluminum Alloy shutter doors from the beginning not to seal, but the curtain sheet with a silencing strip sealinghas been improved, but still did not have the seal. ) the existing Aluminum Alloy shutter door curtain film have two Aluminum Alloy hollow extrusions and Aluminum Alloy filled polyurethane foam materials, extrusiontypecurtain, hardness, making width, protective performance are better than the filling profiles, in accordance with the free choice profile door curtain sheet to the different needs of users.
Q:The difference between aluminized color steel roll and ordinary color steel roll
Aluminized color coated sheet is a new type of material produced in China in recent years due to its high end applications. It is often used as an indication of CCLI. It is made of galvanized steel sheet (55% aluminum, 43% zinc and 1.6% silicon), which is more galvanized and more corrosion resistant. It is processed by surface degreasing, phosphating and complexing treatment, and is coated with organic coating.
Q:The strip tower height
Definition and appearance: the ends of the steel coils are uneven, one circle higher than the circle, showing a different degree of pagoda shape or bread shape.
Q:How are steel tape measures installed?
The spring piece is fixed on the shaft, the other end is connected with the measuring tape core, fixed tape shell with a shaft, the spring plate and a circle around the axis of the ruler core, wrapped after the ruler core extends from the outer end of the incision length of the shell, gently pull, the spring is tightened, the pull out the part from the incision and then removed around the shaft, then gently pull out, and then put the ruler core tied to the shaft, removed from the incision so repeatedly, until the spring to put all the ruler core recovery. Then a cotter pin on the central shaft installed on the lid, will tighten the screws.
Q:What is the maximum width of galvanized steel strip, please? The galvanized coat is 275, and how long is one coil?
But this kind of steel coil is not well processed in the market. At the beginning of Wuhan, several processing plants are good at processing, and other processing plants usually process 1850 at most.
Q:What's the length of a coil of cold rolled steel? Is there a standard?
Generally, according to the volume measurement, each roll weighs 3~15 tons.
Q:Why can hot rolled coils be placed outside?
Because hot-rolled steel coils are generally used as raw material for semi-finished products, they have to be further used for pickling and cold rolling to make more use. The rust and dust can be removed after pickling
Q:Why cold rolled stainless steel sheet is lower than cold rolled stainless steel coil?
Hello! The reason is: 1. cold rolled flat plate is Kaiping;2. cold-rolled plates are negative tolerances.
