Description:
JISG3302 Z18 1.95mm*1000mm Galvanized Steel Sheet Regular Spangle for Automobile Industry
Regular spangle galvanized steel sheet is a type of galvanized steel that displays a characteristic spangle pattern on its surface.
Regular spangle forms during the hot-dip galvanizing process when the steel sheet is immersed in a bath of molten zinc. As the steel is withdrawn from the bath, the zinc coating solidifies and forms distinct zinc crystals on the surface. Regular spangle is characterized by larger and more widely spaced zinc crystals compared to mini spangle or zero spangle.
Regular spangle galvanized steel sheet exhibits a visible and prominent spangle pattern on its surface. The zinc crystals appear as shiny, reflective spots or specks, creating a distinctive, almost star-like pattern. The spangle pattern can vary in size and density, depending on factors such as the zinc bath composition, temperature, and withdrawal speed.

Benifits Of Galvanized Steel:
1. Galvanizing is lower in first cost than many other commonly specified protective coatings for steel. (The application cost of labour intensive coatings such as painting has risen far more than the cost of factory operations such as galvanizing.)
2. Even in cases where the initial cost of galvanizing is higher than alternative coatings, galvanizing is almost invariably cheapest in the long term (because it lasts longer and needs less maintenance). And, maintenance causes problems and adds to costs when structures are located in remote areas, and when plant shutdown or disruption to production is involved.
3. The life expectancy of galvanized coatings on typical structural members is far in excess of 50 years in most rural environments, and 20 to 25 years plus, even in severe urban and coastal exposure.
4. A galvanized coating has a unique metallurgical structure which gives outstanding resistance to mechanical damage in transport, erection and service.
5. Galvanized coatings corrode preferentially to steel, providing cathodic or sacrificial protection to small areas of steel exposed through damage. Unlike organic coatings, small damaged areas need no touch up, etc.
Application:
1. Regular spangle galvanized steel is widely used in the construction industry for applications such as roofing, siding, wall panels, facades, and structural components. Its corrosion resistance, durability, and aesthetic appeal make it a popular choice for both residential and commercial buildings.
2. Regular spangle galvanized steel is utilized in the automotive sector for manufacturing parts such as body panels, chassis components, reinforcements, and exhaust systems. The corrosion resistance of galvanized steel ensures the longevity and protection of automotive parts, even in harsh environments.
3. Regular spangle galvanized steel is commonly used in electrical enclosures, cabinets, and control panels. The corrosion resistance of galvanized steel ensures the protection of sensitive electrical components from environmental factors, etc.
FAQ:
Q1: What is regular spangle galvanized steel?
A1: Regular spangle galvanized steel refers to galvanized steel that exhibits a visible and prominent spangle pattern on its surface. The spangle pattern consists of larger and more widely spaced zinc crystals, giving the steel a textured and decorative appearance.
Q2: How is regular spangle galvanized steel produced?
A2: Regular spangle galvanized steel is produced through a process called hot-dip galvanizing. In this process, the steel sheet or coil is immersed in a bath of molten zinc. As the steel is withdrawn from the bath, the zinc coating solidifies and forms a spangle pattern on the surface.
Q3: How to order?
A3: Buyer sends the inquiry → Buyer gets the quotation → Order confirmation → Buyer send the deposit → Seller prepares goods → Seller makes the strict inspection → Buyer Arranges Balance Payment → packing and delivery.
Q4: Do you have large amount of steel products in stock?
A4: Do you have large amount of steel products in stock?
