Brief Introduction

1. Prepainted Galvanized Steel Coil is coated with organic layer, which provides higher anti-corrosion property and a longer lifespan than that of galvanized steel sheets.

2. The base metal for Prepainted Galvanized Steel Coil is HDGI Steel. The finish coats of Prepainted Galvanized Steel Coil can be classified into groups as follows: polyester, silicon modified polyesters, polyvinylidene fluoride, high-durability polyester, etc.

3. The production process has evolved from one-coating-and-one-baking to double-coating-and-double-baking, and even three-coating-and-three-baking.

4. The color of the Prepainted Galvanized Steel Coil has a very wide selection, like orange, cream-colored, dark sky blue, sea blue, bright red, brick red, ivory white, porcelain blue, etc.

5. The Prepainted Galvanized Steel Coil can also be classified into groups by their surface textures, namely regular prepainted sheets, embossed sheets and printed sheets.

 

Edit

Because there is no after annealing treatment, the hardness is very high (HRB greater than 90), mechanical processing performance is poor, only a simplebending process has less than 90 degree directional (direction perpendicular to the rolled).

3, use three

Edit

Hot rolled products with high strength and good toughness, easy processing and good forming can be excellent performance of welding, which is widely used in ships, cars, bridges, buildings, machinery, boiler, pressure vesselmanufacturing industry.

The scope of application:

(1) after annealing processing into the common cold;

(2) processing galvanized galvanized unit before the annealing treatment;

(3) the basic do not need to process the panel.

Edit

Carbon steel plate, carbon plate, low alloy plate, ship plate, bridge plate, boiler plate, container plate etc.. Rolling hard volumes: under normal temperature,the hot pickling volumes of continuous rolling.

Hot rolled steel strip products include steel (roll) and the shear of steel plate.And steel (coils) can be divided into straight and finishes volume (the volume,smooth rolling and slitting roll).

 

Q:What is the difference between a hot rolled and cold rolled galvanized steel sheet?
The main difference between a hot rolled and cold rolled galvanized steel sheet is the process in which they are made. Hot rolled galvanized steel sheets are produced by rolling the steel at high temperatures, which results in a rougher surface and less precise dimensions. On the other hand, cold rolled galvanized steel sheets are processed at lower temperatures, allowing for a smoother surface finish and more precise dimensions. Additionally, the cold rolling process also tends to make the steel stronger and more durable.
Q:How do steel sheets compare to glass sheets?
Steel sheets and glass sheets have distinct properties that make them suitable for different applications. Steel sheets are known for their strength, durability, and resistance to corrosion, making them ideal for construction, automotive, and industrial purposes. On the other hand, glass sheets are transparent, allowing light to pass through, making them well-suited for windows, mirrors, and decorative elements. While steel sheets provide security and structural integrity, glass sheets offer aesthetics and visual appeal. Ultimately, the choice between steel and glass sheets depends on the specific requirements and intended use of the material.
Q:Can steel sheets be used in architectural or decorative applications?
Yes, steel sheets can be used in architectural or decorative applications. Steel sheets offer durability, versatility, and a sleek aesthetic that make them suitable for various architectural and decorative purposes such as cladding, roofing, wall panels, and interior design elements.
Q:Can steel sheets be used for insulation in buildings?
No, steel sheets cannot be used as insulation in buildings. Steel is a highly conductive material, meaning it allows heat to pass through it easily. Insulation, on the other hand, is designed to resist the flow of heat, keeping the interior of a building warm in winter and cool in summer. Materials such as fiberglass, foam, or cellulose are commonly used for insulation as they have low thermal conductivity.
Q:Are steel sheets resistant to extreme weather conditions?
Yes, steel sheets are generally known for their high resistance to extreme weather conditions. Due to their durable and robust nature, they can withstand harsh temperatures, heavy rain, strong winds, and even hailstorms without significant damage.
Q:What is the difference between a perforated and non-perforated steel sheet?
A perforated steel sheet is a type of sheet metal that has small holes or perforations evenly spaced throughout the surface. These holes serve various purposes such as allowing for better airflow, drainage, or filtration. On the other hand, a non-perforated steel sheet does not have any holes and has a solid surface throughout. The main difference between the two is the presence or absence of these perforations, which determines their specific functions and applications.
Q:Can steel sheets be used for insulation?
Steel sheets are not suitable for insulation as they lack the ability to retain heat or prevent effective heat transfer due to their good conductivity of heat and electricity. Instead, steel sheets can even conduct heat and cold, rendering them ineffective as insulators. On the other hand, materials like fiberglass, foam, or cellulose are far superior for insulation as they excel at trapping and preventing the transfer of heat, making them the ideal choice for insulation purposes.
Q:How are steel sheets protected during transportation by sea?
To ensure the safety and prevent damage of steel sheets during transportation by sea, various measures are taken. One commonly used method involves applying a protective coating to the sheets. This coating acts as a barrier against moisture and saltwater, which are the main culprits behind corrosion during sea transportation. The coating can be a temporary solution, such as a layer of oil or wax, or a more permanent option, such as a layer of paint or zinc. Moreover, steel sheets are often bundled or placed in shipping containers for added protection. These bundles are secured with straps or wires to prevent movement and potential damage in rough sea conditions. The shipping containers themselves are designed to withstand the challenges of sea transportation and shield the steel sheets from exposure to the elements. Additionally, the sheets may be wrapped in plastic or other waterproof materials to provide an extra layer of defense against moisture. This helps prevent direct contact with seawater or rain, thus reducing the risk of corrosion. During the loading and unloading processes, proper handling techniques are employed to minimize the risk of damage. Cranes or forklifts are carefully used to lift and move the steel sheets, ensuring that they are not dropped or subjected to excessive force that could cause dents or bends. Overall, a combination of protective coatings, secure packaging, and proper handling techniques is utilized to safeguard steel sheets during sea transportation. This reduces the likelihood of damage and ensures that they reach their destination in optimal condition.
Q:How are steel sheets protected during storage in humid environments?
Steel sheets are protected during storage in humid environments by applying a protective coating, such as a layer of oil or zinc, which acts as a barrier against moisture and prevents corrosion. Additionally, proper packaging and storage techniques, such as using moisture-absorbing materials and maintaining appropriate temperature and ventilation, are employed to minimize the exposure of steel sheets to humidity.
Q:What is the difference between a painted and laminated steel sheet?
A painted steel sheet is coated with a layer of paint, while a laminated steel sheet has a layer of plastic or other material laminated onto the surface. This makes laminated steel sheets more resistant to scratches and damage, while painted steel sheets offer a wider range of color options.
