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

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:What is a cold rolled sheet with plastic sprayed?
First, cold rolled steel sheet:Cold rolled steel plate is cold-rolled steel plate, commonly known as cold plate. Cold rolling is a steel plate that is further rolled to the target thickness at room temperature. Compared with hot rolled steel sheets, cold-rolled steel sheets are more accurate, smooth and beautiful in appearance and superior in mechanical properties, especially in terms of machinability. The minimum thickness of cold rolling is below 0.1--8.0MM, and the minimum thickness and width are determined by the equipment capacity and market demand of each plant.
Q:What is the difference between an open plate and an original plate?
From the point of view of two kinds of steel material without distinction, general specification of thin strip, narrow width, tolerance requirements are high, but the strip roughness was poor single open flat rolled steel plate. And it is exactly the same as the original flat material, but because the plate is after uncoiling, leveling, shear processed steel belt, the comprehensive mechanical performance is not as good as the original flat, so some important occasions the use of the original plate, should pay attention to in the procurement
Q:What is the hardness of the wear-resistant steel plate?
The microhardness of the wear-resisting layer of the wear-resisting steel plate can reach HVl700 ~ 2000, and the surface hardness can reach HRc58 to 62. The wear-resistant layer of the wear-resistant steel plate is mainly made of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbides in the metallographic structure are distributed in a fibrous direction, and the direction of the fiber is perpendicular to the surface.
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:Are there any restrictions on the thickness of the steel plate, such as the minimum thickness of the steel plate?
No minimum, no maximum, no requirements, what kind of plate can be welded, but the welding method is not the same as welding equipment.
Q:What kind of steel plate is HIC?
Hydrogen sulfide corrosion resistant steel plate is generally used in some specific occasions, LONCIN steel grid plate for you to answer
Q:How much is one meter for laser cutting steel plates?
The above price is for low carbon steel. The price of stainless steel is lower than that of low carbon steel. Mainly nitrogen, a large amount.Of course, the specific price with the processing capacity of the size, the shape of the parts (compare all holes can not be completely by the meter, whether to count) freight, whether it is with material processing have a great relationship.
Q:What is the width of carbon steel coil and the width of stainless steel coil, one is 1250 and the other is 1219?
But the technical content of carbon steel with stainless steel is different, our country in more than 10 years ago the ability of continuous rolling of stainless steel is not high, equipment are imported, the stainless steel mill is dominated by 1219-1300, but also the development of national wide stainless steel 1500-2050, but the price is expensive at least thousands of dollars a ton, after all put the equipment to recover the cost, and the number of business orders is not much, it is difficult to find a spot on the market. Carbon steel countries have developed for many years, technology and equipment are mature, so the market has 1250 as production standards.
Q:What's the difference between hot-rolled seamless steel tube and cold-rolled seamless steel tube?
Cold rolled seamless steel pipe (DIAL) in general, steel pipe for low and medium pressure boiler tube, high-pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking tube and other steel tube, including carbon thin-walled steel, alloy thin-walled steel, stainless steel, thin steel tube.
Q:What is the difference between Q235A steel and Q235B steel?
Materials Q235A and Q235B belong to carbon structural steel. In the national standard GB700-88, the distinction between Q235A and Q235B material mainly in the carbon content of steel, the material is Q235A of steel, carbon content between 0.14-0.22%, Q235B of carbon content of steel between 0.12-0.20%;
