Corrosion Resistance 0.5 x 1220 Regular Spangle Galvanized Steel Sheet 

Galvanized Steel Sheet & Plates, are intended for use where greater corrosion protection is required

without painting. A lower cost alternative to stainless steel, galvanized sheet and plates have a rust

free protection for up to 30 years, while maintaining strength with a durable surface coating. 

2 kinds common used surface

On the surface of galvanized steel, we often see a pattern that looks like it has formed naturally. This

is called spangle. It is actually a pattern formed by the crystallization of zinc elements during the cooling

process after molten zinc is attached to the surface of steel. The formation of spangles is affected by the

cooling rate, temperature control and the chemical composition of the zinc layer.

♦ Regular spangle

regular spangle are known for their unique, rough, petal-like crystals, which give a very strong visual

impact. These spangles are suitable for applications that emphasize visual effects and decorations.

The rough spangle surface helps to improve corrosion resistance, especially in harsh environments

such as marine climates and high humidity areas.

♦ Zero spangle

Zero spangle means that there are almost no zinc crystals and no pattern can be seen, just like an

ordinary piece of metal sheet. The advantage of zero spangle is that the finish is extremely good, and

the coating will be denser and more even.

galvanized steel material application

• Building and Construction Industry

The sturdiness and durability that galvanized sheet metal offers make it popular in the construction industry.

It has been employed in various commercial and residential projects to the highest level.

• Automotive Industry

The use of galvanized steel on vehicles dates many years back. Using zinc-coated bodies on automobiles

has become the norm of car manufacturing. The rust-resistant nature of this material makes it a great 

marketing tool in the competitive market. Several makers leverage them to offer anti-rust warranties to

their customers.

• Telecommunication Industry

Maintaining phone lines isn’t an easy job. They require the toughest and most reliable materials for success.

Galvanized sheet metal offers its uses on phone wiring and equipment boxes. Therefore, there will be

decreased danger of injury and reduced maintenance cost.

• Electric Equipment and Appliances

When you look at most electric appliances around you, you may be able to notice the unique features of 

their casing. Most casings for electrical equipment use galvanized steel material. In fact, it is not surprising

that some interior parts of these appliances are made from this steel material.

export forms and common dimensions

We can export the galvanized steel material with 3 kinds form, coil, strip and sheet,

customers need to choose it accrording to their actual application.

For the sizes, it has some regular used widths, 24 inch  (610mm) 30 inch (762mm)
