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 clientsmay help you sincerely: 

1.How about your company

A world class manufacturer & supplier of castings forging in carbon steel and alloy steelis one of the large-scale professional investment casting production bases in China,consisting of both casting foundry forging and machining factory. Annually more than 8000 tons Precision casting and forging parts are exported to markets in Europe,America and Japan. OEM casting and forging service available according to customer’s requirements.

2.How to guarantee the quality of the products

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

3. 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:Are lead contained in galvanized steel plates and plain steel plates?
Steel plate is made of molten steel, cooled and compressed into flat steel.
Q:What is hot and cold rolled steel plate? How to distinguish? What high hardness? Which will produce noisy eye?
As the name suggests, hot rolling, rolling temperature is high, so the deformation resistance is small, can achieve large deformation in rolling steel plate. For example, the general continuous casting slab thickness is about 230mm, and after roughing mill and finishing mill, the final thickness of 1~20mm. at the same time, because the steel plate width thickness ratio is small, the size precision is relatively low, not easy appear the flatness problem, mainly to control the convexity. For the organization required, generally through controlled rolling and cooling control is realized, microstructure and mechanical properties of the rolling temperature, finishing temperature and coiling temperature to control strip finishing. Cold, generally in the heating process is not open before rolling. However, because the strip thickness is small, it is easy to appear the flatness problem. Moreover, after cold rolling is finished, therefore, in order to control the dimensional accuracy and surface quality of steel strip, using a lot of tedious process. The cold rolling production line, equipment, process complex With the user to improve the shape and surface quality of the strip size precision, plate, cold rolling mill control model, L1 and L2 system, the shape control means relative to hot. And temperature is one of the important control index of rolls and strip.
Q:What does steel plate "A3" mean?
Using Q235 steel as punch material, after quenching without tempering, direct use, hardness of 36~40HRC, solved the punch in use in the phenomenon of fragmentation
Q:What is AO steel plate?
The locking plate is fixed to connect without bone friction, but rely entirely on the steel plate interlocking structure to achieve. The steel plate and the bone surface can leave the gap, to eliminate the adverse effects of contact with bone plate stress, greatly improve the blood supply and the growth of periosteum and recovery. Screw and plate angle fixed, plate and screw and the backbone form the stereo than ordinary AO plate fixation, locking plate fixation is more stable.
Q:Is 5mm thick steel plate tapping M8 thread reliable?
With 5mm steel plate upside M8 thread, with M8 screw, that depends on what you use it to do? Check the strength of the screws at M8 (different grades, different intensities) to see if you are reliable and unreliable.
Q:Is galvanized iron sheet the same as galvanized steel sheet? solve
The same thing is done to slow down the rate of oxidation. Because the zinc is more active than the iron, the zinc first responds, the zinc reaction is finished, iron should. Thereby slowing down its oxidation.
Q:What material is steel plate against drilling?
All high nickel, high tungsten, or both titanium (tungsten carbide and titanium carbide), cobalt, molybdenum, niobium and other elements of the steel can be drilled.
Q:What is the thickness of the paint board?
Paint plate generally in accordance with the "block" as the unit sales, not only as a wall decoration, doors, tables and chairs can do the shelves, cabinets bearing surface, the thickness of 1-2 cm in length, 50 - 120, 30 cm wide case is 55*30*1.5cm
Q:Which is good, z15 grade steel plate and z25 grade steel plate?
Both Z15 and Z25 are the properties of steel against lamellar tearing. Their properties are marked by the fracture shrinkage index of tensile specimens in thickness direction (15 and 25 in Z15 and Z25 are the minimum values of fracture shrinkage)
Q:Why should the back of the steel sheet pile cofferdam be pumped after the construction of the pile cap?
The appearance of surface defects of steel sheet pile, length, width, thickness, end rectangle ratio, flatness and lock shape content of inspection, do not meet the requirements of steel sheet pile is corrected, in order to reduce the difficulties in piling process.
