Product Description

Prepainted Galvanized Steel Sheet for sale

Prepainted galvanized steel sheet is a kind of colour coated steel sheet (PPGI sheet). It uses galvanized steel as the base metal. The zinc layer offers strong corrosion resistance. Plus with painting, it is more durable than galvanized steel.Metal in China® (XINTUOYUAN) mainly provides PPGI Roof sheet and PPGI Flat Sheet series products, which are available in various sizes, colors and designs. The most popular PPGI colors include Traffic Red (RAL 3020), Sky Blue (RAL 5015), Signal White (RAL 9003), Moss Green (RAL 6005), Traffic Black (RAL 9017), etc. You can also customize colors and patterns. As a wholesale manufacturer in China, we will also offer factory direct prices.

Calculate Weight of PPGI Sheet

You can estimate the weight of your PPGI sheets with the following formula:

Thickness (mm) * Width (m) * Length (m) * 7.85 = (kg/pcs)

Note: 7.85 is the density of iron. It means per cubic meter of iron weighs 7.85 tons.

Color coated Galvanized Steel Manufacturing Process

Color-coated galvanized sheets are generally produced by secondary cutting of color-coated galvanized coils. Color-coated galvanized corrugated sheet is mechanically pressed on the basis of color-coated galvanized sheet. With the most advanced facilities and technology, Metal in China®(XINTUOYUAN) has a set of manual and automatic production system for galvanized coils, which can meet customers’ requirements for different parameters and high performance of products.

production-process-of-Galvanized-steel-coil

1. Pre-Treatment Process

Some rolling oil and other contaminants remain on the surface of cold rolled steel sheets following processing. These are removed by passing the electrically charged sheet through an alkaline solution which induces an electrochemical reaction.

2. Annealing

The material properties of the pre-treated steel sheet can be altered and improved through recrystallization during the annealing process.

3. Hot-Dip Galvanizing

After passing through the annealing furnace, steel sheets are dipped into a zinc pot where molten Zn is coated onto the surface. The desired coating weight is achieved by removing excess zinc before solidification with high-pressure air from an air knife.

4. Galvannealing

The surface of a steel sheet, after the air knife, can be coated with a zinc compound prior to reheating in an annealing process. Zn atoms diffuse into the Fe to create a Zn-Fe series alloy.

5. SPM & Chemical Treatment

In order to achieve a flat surface and an elegant finish, the steel sheet is processed with a skin pass mill. In order to prevent the white rust, which often forms on the surface of activated zinc, and to improve corrosion resistance, the surface is coated with a Cr-free resin.

6. Inspection & Coiling

Located at the line’s exit section are a side trimmer, inspection table, oil coating machine and coiling equipment. At this station, all products are inspected and judged relative to material specifications required by the customer.

PPGI Sheet Applications

There are different designs of pre-painted GI sheets, including profile sheets and plain sheets. They are widely used in construction, household appliances, transportation, furniture, etc. The data shows that 31% is used in home appliances and 63% in construction. Below are some of the main industries where PPGI is used.

Additional steel processing services

cutting Service

For parts that require extremely high wear resistance, we use abrasive waterjet cutting to maintain hardness throughout the part without creating a heat-affected zone. For thicker plates up to 200mm, we use precisely controlled CNC oxy-fuel cutting. For products requiring high cut quality and dimensional tolerances, we use high-definition underwater plasma cutting to maximize plate performance in abrasive applications.

frequently asked questions

What is pre-painted galvanized steel?

What is the difference between galvanized and pre galvanized?

Pre-paint steel is a bare metal substrate or corrosion resistant substrate that has had paint applied to both sides through a continuous coil coating process, which produces a uniform paint finish. The metal is unwound, cleaned and chemically treated during the process.

As mentioned, pre-galvanized components are usually only immersed in the galvanizing bath for a very short time, resulting in a relatively thin coating. The thicker zinc coating produced by hot dip galvanization offers improved rust and corrosion protection versus pre-galvanization.
