Product Description:

Hot-dip Zinc Coating Steel Building Roof Walls 
1.Structure of Hot-Dip Galvanized Steel Sheet Description:


Hot-dip galvanized steel coils are available with a pure zinc coating through the hot-dip galvanizing process. It offers the economy, strength and formability of steel combined with the corrosion resistance of zinc. The hot-dip process is the process by which steel gets coated in layers of zinc to protect against rust. It is especially useful for countless outdoor and industrial applications. Production of cold formed corrugated sheets and profiles for roofing, cladding, decking, tiles, sandwich walls, rainwater protective systems, air conditioning duct as well as electrical appliances and engineering.


2.Main Features of the Hot-Dip Galvanized Steel Sheet:

• Excellent process capability

• Smooth and flat surface

• Workability, durability 

• Excellent anticorrosive property

• High strength

• Good formability

• Good visual effect

5.FAQ of Hot-Dip Galvanized Steel Sheet 

We have organized several common questions for our clients,may help you sincerely: 


1.How to guarantee the quality of the products?

We have established the international advanced quality management system,every link from raw material to final product we have strict quality test;We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.


2. How long can we receive the product after purchase?

Usually within thirty working days after receiving buyer’s advance payment or LC. We will arrange the factory manufacturing as soon as possible. The cargo readiness usually takes 15-30 days, but the shipment will depend on the vessel situation.

Q:The method of making spring steel for automobile?
The south is the car plate making machetes bow. Hardness enough. It is important to quench the heat. A big jump makes a big mouth. Soft edge. Special blacksmith needs to be quenched
Q:What's the difference between the three kinds of pickling plate, cold rolled plate and hot rolled plate?
Cold rolled plate: that is, the cold rolled base plate (that is, hot rolled plate) rolled in the normal temperature condition. Because of the great cold rolling stress, it usually goes through the annealing process
Q:How thick is steel filing cabinet usually made of steel plates?
A lot of people will hold 0.6 of the said 0.8 material, this is because the cold rolled plate after forming electrostatic spraying powder and environmental protection, so it is actually only 0.6mm 0.8mm bare steel, on this point, if you are purchasing large quantities of words, can use vernier caliper to card
Q:What is muotileaved spring? What is the little leaf spring?
Leaves: by the middle thick and thin steel sheet at both ends of the superposition of equal width. The plate section changes little leaf spring, from the middle to both ends of the cross section is gradually different, therefore the rolling process is more complex, the price is expensive than multi leaf spring. Compared with less leaf spring leaf spring, in the same stiffness (i.e. the same carrying capacity) under the condition of less than the spring leaf light is approximately 50%, reducing fuel consumption, increased ride comfort. And between the little leaf spring monolithic contact, reduces the relative friction and vibration, the ride comfort is increased.
Q:What does "rolled steel" mean?.
Rolling is a rolling process, the plate is kind of calendering material, not only some specific material, it can contain stainless steel and carbon steel materials, stainless steel with thickness of steel production for example, now the tolerance basic law, but in order to achieve a certain thickness
Q:Can Q460C steel plate be used as Q235 steel plate?
Q460 Q235 is not recommended when using their mechanical properties, the gap is too large, the yield strength of Q460 basically is 2 times that of Q235, the elongation is worse than that of Q235, but the problem is not used alone, if used in combination with other components, the effect is not very good, but also not conducive to the overall structure of the force transfer, like cotton in the wire, when the tensile force, most will function in the small deformation component, with low elongation, brittle fracture, which is why when substitute materials are used as close as possible. If you want to weld, it is even more troublesome, Q460 welding performance is poor, the welding process requirements are high, can not be treated as simple as welding Q235, which is also an increase in cost.
Q:Are there any restrictions on the thickness of the steel plate, such as the minimum thickness of the steel plate?
If the intensity is enough, you should be the first 4mm for the economy. Carbon steel plate, with electrode arc welding, 2 diameter welding electrode on line.If it is stainless steel, tungsten argon arc welding is better
Q:Stainless steel drawing plate, polishing plate, mirror panels of the three differences
Stainless steel polishing plate refers to: stainless steel polishing plate refers to the polished stainless steel polished plate through the polishing machine, this kind of polishing board generally brightness is not high, but also can shine out of fuzzy figure.
Q:STCC what's the quality of the cold rolled steel sheet?
Cold rolled steel: rolled without heating at room temperature (strictly speaking below the recrystallization temperature).
Q:What is the width of carbon steel coil and the width of stainless steel coil, one is 1250 and the other is 1219?
A continuous rolling mill is put in billions of dollars, but this is the rolling mill, and there are many gold furnaces.
