What is Pre-painted Galvanized Iron and How to Use It?
Galvanised Iron (GI) is a metal alloy; either steel or iron, that has a layer of protective zinc coating applied to the surface to prevent rust. Prized for its protective steel properties in its zinc coated form, GI makes the perfect finished steel product for the industrial and construction industry. The most commonly used processing method, which we use here at Camasteel, is through hot-dip galvanizing.
Galvanized Iron (GI)Galvanized Iron (GI)
Pre-painted galvanized iron (PPGI) is another form of GI, formed in a similar process. The process is extended where it refers to factory pre-painted alternative to the zinc coated steel. The hot dip metallic coating process, where the iron is submerged in molten zinc is typically used to coat steel sheet and coil which may all be factory pre-painted like PPGI.
What is Galvanized Iron (GI) and Pre-Painted Galvanized Iron (PPGI)?
PPGI is color coated GI steel, sold in coils or sheet forms, including profile sheets and plain sheets. It is one of many steel products offered here at Camasteel. This pre-painted steel has characteristics of high durability, and resistance against adverse weather and UV rays from sunlight.

Other uses of PPGI (prepainted galvanized steel coil) for the furniture industry are:
PPGI can be used to build electrical cabinets, which in turn are used to store and preserve electrical or electronic equipment.
The material structure of the pre-painted galvanized steel coil is composed of galvanized sheets as a metal base, with zinc coating serving as a layer. The overall thickness of Camasteel PPGI is 0.12mm to 2.0mm:
The base metal in PPGI is usually cold-rolled steel, Camasteel uses a hot-rolled technique which gives the galvanized iron its strength and durability.
A hot dip metallic coating process is applied to coat the steel sheet and coil. In this hot dip galvanizing method, the base metal is submerged into molten zinc to add the protective coating.
Chemical pretreatment, otherwise known as chemical conversion treatment is where the chromate coating is added for extra protection.
In prepainted galvanized iron, the product is painted before the hot dip metallic coating process.
Whilst the back paint thickness is roughly 5-20μm, the top paint thickness is 10-25μm. This helps to ensure the longevity of the product's beauty and use.

Choosing the correct pre-painted steel coil can be achieved by first assessing your natural environment, along with use environments, and structural characteristics of the building to match the appropriate steel grade are among the most important things to consider when choosing an appropriate pre-painted steel coil to match with the required specifications.
This is determined by properties of the chosen material (yield strength, elongation and malleability), performance of metallic coating, considering the metallic coating type, girth, and adherence, and coating performance; coating species, color, sheen, endurance, workability, etc.
The main consideration for the selection of color-coated steel sheets is geographical due to weather implications and how corrosive the environment may be.
Due to the beauty and durability being a key selling point for the use of PPGI on civil buildings, it is imperative that the coating resists discoloration and pulverization.
To understand the pricing of PPGI, you must first understand the characteristics and what to look for. The specifications of the prepainted galvanized iron will be an indicator of the price.
The thinner the base steel thickness, the higher the price of the ppgi steel coil, because the processing cost becomes higher. As a wholesaler, we will offer discounts for bulk-buy orders, book a call to hear our latest offer and promotions!
You can calculate the weight of your PPGI sheet steel, with just four pieces of data:
Length (m) * width (m) * thickness (mm) * density = (kg/pcs)is the ultimate formula for accurate measurement!
To ease the process, we have listed the densities of metals commonly bought in coil and sheet form:
Material Density (g/cm³) Steels 7.85 Stainless steel 7.9 Aluminum 2.7 Iron 7.87 Zinc-titanium 7.2 Copper 8.93Density variations in painted, alloy, or coated steels are minute and can be disregarded. It is imperative that any end results arrived at via self-calculation or utilizing steel calculator tools online, should be considered estimations, rather than exact calculations.
The approximate coil weight can be determined by measuring the Density (D), Thickness (T), along with the Outside (OD), and Inside Diameter (ID).

The first would have to be the Intact zinc coating on GI by Camasteel that prevents corrosive substances from breaching the surface of the underlying steel or iron. This longevity and resilience make PPGI the perfect building material!
The differences between PPGI and PPGL can be analyzed with regards to substrates, durability, weight, appearance, features, applications and price:
PPGI uses a galvanized steel substrate as base metal. These galvanized sheets have a layer of zinc coating. However, PPGL uses galvalume cold-rolled steel sheets as a substrate. Galvalume sheets for PPGL are coated in 55% aluminum, 43.3% zinc, and 1.6% silicon.
PPGL sheets have a higher resistance against PPGI sheets, due to the dense layer of aluminum, which prevents the base metal from eroding.
The surface of a PPGL sheet is smoother than PPGI sheets. This is because aluminum is more adhesive than zinc.
PPGL is 3x more durable than PPGI; AI-ZN coating in PPGL is more resistant to corrosion, in comparison to the ZN-rich in PPGI.
Due to the lesser weight of aluminum when compared to Zinc, PPGLs AI-ZN coating is lighter than PPGIs zinc coating. Although, AI-ZN coating can occupy 3% more space than the GI sheet, even with the same weight.
PPGI and PPGL can be used for industrial and commercial purposes, including; automobiles, wall paneling, roofing etc. However PPGL is more suitable for adverse outdoor environments, due to its high corrosion resistant features.
PPGI sheets are 3%-11% lower in cost than PPGL sheets, due to varied, but minute reasons of process and material variance, durability and feature differences.
PPGI steel coil proves more aesthetically pleasing due to the color and smooth appearance. It is light in weight, making it cheaper and easier to transport, especially in bulk! PPGL on the other hand is more expensive but the product lasts longer.
PPGL can also withstand up to 315 &#; temperatures, due to the higher density aluminum coating. Book a quick consultation/take a look at our pricing breakdown page to see how we can customize the selection and distribution process for you!
