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.

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

• Excellent process capability

• Smooth and flat surface

• Workability, durability

• Good formability

• Good visual effect

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: What is the (balanced) chemical equation for steel?: Steel is about 5% carbon and about 89 % iron, the rest is impurities of all sorts That is considered low carbon steel There are precise formulas for other steels like High Speed Steel, High Tensile low carbon, and thousands of other steels. Specialty steels are a big business item with thousand of tons sold each year for specialty applications.

Q: What are the different types of steel coil packaging materials used during processing?: Some of the different types of steel coil packaging materials used during processing include steel strapping, plastic strapping, stretch film, shrink wrap, and coil covers.

Q: How are steel coils transported and stored?: Steel coils are typically transported using flatbed trailers, coil carriers, or railcars. These coils are securely strapped or banded to prevent movement during transportation. Once they reach their destination, they are usually stored in warehouses or outdoor storage yards. The coils are stacked on top of each other, often with the help of specialized equipment, to optimize space utilization. They may also be stored horizontally on racks or stored vertically in specially designed coil racks. Proper handling and storage procedures are followed to ensure the safety of personnel and to prevent damage to the steel coils.

Q: Suppose you made a sword out of diamond (just follow me here, it's only theoretical). Would it be lighter than a sword of the same size made out of steel?: steel is heavier. 6.5 mm/1 carat of steel is 7 grams, while diamond is 1/5 a gram

Q: a concrete or steel building?also, what is the density of concrete and steel? is concrete heavier in steel for the same volume?: Steel is heavier than concrete for the same volume, however steel buildings are generally lighter. This is because steel buildings utilize high strength of steel, so volume of steel in steel buildings is much smaller than volume of concrete in concrete buildings. In another words in steel buildings much less volume of material is needed for the same strength compared to concrete buildings.

Q: I want to know the special characters or the advantages of the corton steel. In what cases it is recommended to use?Thank you.: *It is Corten steel.Grade A B. *Weathering steel, best-known under the trademark COR-TEN steel, is a group of steel alloys which were developed to obviate the need for painting, and form a stable rust-like appearance if exposed to the weather for several years. United States Steel Corporation (USS) holds the registered trademark on the name COR-TEN. Although USS sold its discrete plate business to International Steel Group (now Arcelor-Mittal) in 2003, it still sells COR-TEN branded material in strip-mill plate and sheet forms. In some areas it may be known without the hyphen as Corten steel. The original COR-TEN received the standard designation A242 (COR-TEN A) from the ASTM International standards group. Newer ASTM grades are A588 (COR-TEN B) and A606 for thin sheet. All alloys are in common production and use. It is a weather-resistant steel which is used in containers and hot flue gas line. The American Corten A Steel has a composition of C, 0.12; Si, 0.5; Cu, 0.5; Cr, 0.8; P, 0.1 and Mn, 0.5%. Although the tensile strength is less than 494 MPa the yield is in the region of 371 MPa. The combination of copper and phosphorus also increases the resistance to atmospheric corrosion which is important when thinner plates are used. The original steel A suffers a decrease in yield strength and notch ductility in thickness over 25 mm, to overcome which Corten B was developed-C 0.14; P 0.04; Mn 1.1; Cr 0.5; Cu 0.4; V 0.1; Bol Al 0.02. *COR-TEN A applies to plates up to 12.5mm in thickness, COR-TEN B applies to plates up to 50mm in thickness. *It has been used in bridge and other large structural applications such as the New River Gorge Bridge, the newer span of the Newburgh-Beacon Bridge, and the creation of the Australian Centre for Contemporary Art (ACCA). It is very widely used in marine transportation, in the construction of shipping containers.

Q: What is the role of steel coils in the production of fencing materials?: Steel coils play a crucial role in the production of fencing materials as they serve as the primary raw material for manufacturing various types of fences. These coils are typically uncoiled, cut, and shaped into individual fence components, such as posts, rails, and pickets. The strength and durability of the steel make it an ideal material for fencing, ensuring that the final product can withstand harsh weather conditions and provide security for a long time.

Q: How are steel coils used in the marine industry?: Steel coils are commonly used in the marine industry for various applications such as shipbuilding, offshore drilling platforms, and marine infrastructure. These coils are used to manufacture hull structures, decks, bulkheads, and other components, providing strength and durability needed to withstand harsh marine environments. Additionally, steel coils are also utilized in the production of marine equipment and machinery, ensuring the reliability and performance of marine vessels and structures.

Q: How are steel coils coated to prevent corrosion?: Steel coils are coated to prevent corrosion through a process known as galvanization. This involves applying a protective layer of zinc onto the surface of the steel coils. The zinc acts as a barrier, preventing the steel from coming into contact with moisture and oxygen, which are the main causes of corrosion. This coating not only provides excellent corrosion resistance but also enhances the durability and longevity of the steel coils.

Q: The length of a steel beam increases by 0.78 mm when its temperature is raised from 22 degrees C to 35 degrees C. What is the length of the beam at 22 degrees C (in meters)?I used: L = (0.78 mm)/[(9/5)(.00000645 F)(13)] = 5.17 meters but Mastering Physics said Not quite. Check through your calculations; you may have made a rounding error or used the wrong number of significant figures. I'm confused because this is how we learned this kind of problem in class, so if anybody knows what I did wrong, feel free to correct my errors! Thanks: It seems you are trying to convert celsius to Fahrenheit, Why? There is no need. Delta L= alpha (initial length) (delta celcius) what you need is an alpha, it should be given in degrees celsius to the negative first (steel's alpha happens to be 0.000036 1/celsius). You also need the length of the beam at 35 degrees C. This answer (delta L) needs to be added (if heat is rising) or subtracted (if heat is dropping) to the original length.
