What Is PPGL Steel Coil?

PPGL is short for “pre-painted-galvalume-steel”, which uses galvalume steel as substrate. The galvalume coating is similar to galvanized coating. It is made of 55% aluminum, 43.4% zinc, and 1.6% silicon. Due to the aluminum, the galvalume steel has excellent heat resistance durable ability, and anti-oxidation performance. They will not leech into the water and mud with higher corrosion resistance. Hot-dip galvalume steel coils are the ideal steel materials for water heating machines, food dehydrators, exhausted tubes, automobile mufflers, and structural sections. So the PPGL steel contains several layers, including top painting, primer coating, chromate coating, Al-Zn alloy coating, base metal (cold rolled steel sheet), Al-Zn alloy coating, chromate coating, and back painting (top and primer coatings).

Benefits of PPGL Steel

1. Wide Applications

Pre-painted galvalume steel coil is an innovative product made in recent years by combining the strength of steel with the anti-corrosive capabilities of metal coatings like aluminum and zinc. The material is exceptionally resistant to environmental degradation. PPGL coils exhibit a high degree of strength and are used in a wide variety of applications such as roofing & cladding, automatic doors, fencing, lighting, internal partition, ceiling accessories, vehicle manufacturing industry, and steel furniture industry, home appliance industry, and shipbuilding industry.

2. Easy to Process

Pre-painted galvalume steel can be pressed, punched, roll-formed, or joined in any way to provide some of the best steel products on the market today. They are strong but lightweight for easy placement and are long-lasting. This superior quality steel product doesn’t easily crack under pressure and is manufactured to display high strength and tolerance. This article provides information on the many benefits of using PPGL steel coil for your commercial and residential construction projects.

3. Great Adhesion

One of the biggest advantages of investing in PPGL steel coils is the superior quality of its coating. The coating can be applied to both sides of the material to produce uniform results. The product is consistent in color, thickness, texture, and performance. This superior steel product is more eco-friendly compared to many other steel products on the market today. It eliminates imperfections such as uneven applications and oil and dirt residue. That is why you need to invest in PPGL steel for your construction projects.

4. Excellent Corrosion Resistance

PPGL steel is uniformly treated with two coats of paint to make sure the material has a tight bonding to resist corrosion and enhance long-term durability. This corrosion-resistant product easily outperforms most of the other steel products on the market today. On the other hand, PPGL steel is proven to be extremely versatile for your construction projects. You won’t regret the decision to invest in pre-painted galvalume steel for your construction project because of the numerous benefits provided by the product.

Distinction Between PPGL Steel Coil and PPGI Steel Coil

PPGI and PPGL sheets are two various kinds of color coated steel, which are extensively utilized in numerous markets, for example, marketing, building and construction, transport, home appliance market, etc. They are really comparable. However, there are still some differences. So, what are the distinctions between PPGI as well as PPGL sheets? Keep reading for details.

1. Various Base Metal

PPGI is short for pre-painted galvanized steel, while PPGL is short for pre-painted galvalume steel. As the name suggests, PPGI steel makes use of galvanized sheet (with a layer of zinc covering) as the base metal. While PPGL is with galvalume sheet as substrate, which is coated with 55% aluminum, 43.3% zinc, and also 1.6% silicon. This is the main distinction between PPGI as well as PPGL, which will further influence their attributes and also applications.

2. Life Span

As mentioned, both zinc coating, as well as Al-Zn covering, are made of to secure the metal from rusting to lengthen its life span. For the GI sheet, the base metal will certainly be harmed when the zinc coating is all worn away. Typically, a galvanized sheet might last for 10 to 15 years. While lightweight aluminum and also zinc alloy kind of tiny bit locations. The Zn-rich phase will certainly rust preferentially, while the Al-rich stage will certainly corrode very slowly. So Al-Zn layer is more corrosion-resistant than zinc-coated steel sheet. According to data, the service life of PPGL steel is 3 times longer than that of PPGI steel. Below are some pictures for you.

3. Appearance

The surface area of the PPGL sheet is smoother than that of the PPGI sheet. It is due to the far better attachment of light weight aluminum than zinc. For the exact same reason, PPGL sheets can be painted straight without pre-treatment. Nonetheless, it is required to be pre-treated for galvanized sheets.

4. Various Attributes

The warm resistance of the PPGL sheet is better than that of the PPGI sheet. PPGL sheet can stand up to temperatures of 315 ℃. Additionally, PPGL sheets have better deterioration resistance than PPGI. It is since the dense layer made from light weight aluminum can avoid the base steel from additional wearing down.

Since there is a difference when it comes to their coatings, the PPGL steel coil and the PPGI steel coil also vary when it comes to their properties:

– PPGL steel coil provides a more refined and smoother finish when compared to the PPGI steel coil.

– Corrosion that occurs in PPGL steel will spread. While in PPGI steel the corrosion will remain localized, meaning that it won’t spread as easily.

– PPGL steel is more resistant to corrosion when compared to PPGI steel, however, the cut edges will be less protected. This has to do with the honeycomb structure of the steel coating, which fails to provide enough protection to the exposed edges.

Which One Is Right for Me?

Except for the differences, PPGI & PPGL sheets are likewise very similar. Both of them have useful features, such as excellent deterioration resistance, formability, and also relieve to repaint on. Both are commonly made use of in building and construction, shipbuilding, vehicle production, furniture, electric industry, and so forth.

What Are PPGL Steel Coils Used For?

The PPGL coil is a cold-formed product that is processed into a metal roofing product with the use of a roll-forming machine, mainly used in commercial, industrial, residential and civil buildings. The PPGL with a wood grain color or effect is also commonly used for exterior doors to mimic or resemble wood.

How To Choose PPGL Products?

Before choosing PPGL steel coils, color and thickness are usually the main considerations to keep in mind. Another important consideration to keep in mind is the mechanical characteristics of the actual substrate, including yield strength.

Other considerations also include how much the coating weighs on the galvanized steel sheets, along with the painting performance of the PPGL which includes durability, powder resistance, and thickness.

PPGL is a versatile and innovative product that combines the anti-corrosive abilities of coatings and strong and robust steel. These materials are especially resistant to high temperatures and corrosion and can withstand temperatures up to 315 degrees Celsius.

PPGL coils are commonly used for many applications including windows and doors, cladding and roofing, fencing, internal partitions, lighting, furniture, ceilings, ship manufacturing, the building sector, and automobile manufacturing industry. Wanzhi Steel is a reliable and reputable manufacturer of PPGL coils and PPGI coils. The coils that they produce are available in widths that range from 600 to 1,250mm, and thicknesses that range from 0.12 to 1.2mm. These products are also available in a wide range of attractive and eye-catching patterns and colors, to match a wide range of building applications.
