Product Description:

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.

Q:How is the normalized steel plate produced?
Normalizing, also known as normalizing, is to heat the workpiece between 727 and 912 degrees Celsius. 40~60min, after a period of heat preservation, is removed from the furnace and cooled by air or by spray, spray, or blow cooling. Its purpose is to make grain refinement and carbide distribution homogenization, to remove the internal stress of materials.
Q:What material can be used for A36 steel plate?
Q345 is a kind of steel material. It is low alloy steel, widely used in bridges, vehicles, ships, buildings, pressure vessels, special equipment and so on.
Q:Must the welding between steel sheets be opened?
Not necessarily, very thin plate, no opening, but also guarantee penetration, but also through nondestructive testing
Q:What type of welding rod is used for steel Q245R and Q235B material?
If the smaller diameter of the cylinder, the inner wall of the can go in welding, open V groove on the weld position, the use of manual TIG welding primer (ER50-6 wire), welding electrode (J507 electrode) filling cover, if the wall thickness is more than 10mm, you can also consider the use of submerged arc welding (filling cover H08MnA HJ431 solder wire);
Q:Why is the water stop steel plate placed in the middle of the wall?
A water stop steel plate is an ordinary thin steel plate, not a waterproof coiled material, not a rubberized fabric, but imagine if a steel plate is placed on the outside of the concrete wall
Q:Bathroom washing machine, galvanized steel and color steel which good?
The outer shell of a washing machine, even if it is a zinc plated steel sheet, usually adds a beautiful coating to the surface, equal to double protection
Q:What are the driving methods for steel sheet piles?
Mechanical hand general construction pile length of less than 12m steel pile; more than 12m length generally use crawler crane combined with vibration hammer construction, if the surrounding environment is sensitive to vibration, can use Japanese static pressure pile driving machine construction. The vibration hammer: DZ40 DZ45DZ60 DZ90 DZJ120; ordinary steel sheet pile, DZ60 type vibrating hammer.
Q:What is the difference between a steel strip and a coil? The steel strip is flat steel, and the steel coil is made of steel. Is that correct?
A steel strip is a steel strip of relative range, and can be called a steel strip when the width is less than 1000.
Q:What is a water stop steel plate?
The joint position is called the new and old concrete construction joints, the waterproof concrete belongs to the weak links, increase the sealing plate, the water along the slit Jiecha position of the new and old concrete permeability met when the sealing plate can not leaking, sealing steel plays a role to cut off the water penetration path. In time, the steel plate is penetrated along the gap between the water stopping steel plate and the concrete, and the water stopping steel plate has a certain width, and the seepage path of the water is prolonged, and the utility model can also play a waterproof role.
Q:What is the difference between color steel plate and hot galvanized sheet?
Color coated substrate of galvanized plate, color coated sheet is coated galvanized plate, some color is aluminium zinc substrate, but now on the market only a few in the Al Zn substrate coated board.
