Galvalume Steel Coil Manufacturer and Factory Leading Supplier from China

Taian Geruis New Material Co.,ltd. is one of China leading galvalume steel coil manufacturers and supplying chain supplier for galvalume coils which also called aluzinc steel coils with 55% aluminum, 43.5% zinc and 1.5% silicon alloy metal coating layers, we are manufacturing, packaging, warehousing, logistics, and financing. We produce more than 3 million MTs annually with maximumly production ability. n various types of construction and industrial projects, it’s vital to have materials that have been shown to be extremely durable and resistant to such factors as rust, corrosion, and other problems. As technology has evolved over the years, one of the most durable materials that have become popular for a wide array of applications is galvalume steel coil. Galvalume steel plate & sheet owns the most premium corrosion resistance property among the coating metals with the metal-plating ratio. The aluminum-zinc alloy coating structure of the galvalume steel sheet is composed of 55% aluminum, 43.4% zinc and 1.6% silicon which is solidified at 600 ℃ temperature. Its whole structure is composed of aluminum-iron-silicon-zinc to form a dense quaternary crystal. Thus forming a layer of strong anti-corrosion factor to prevent corrosive penetration through the barrier.What is Galvalume Steel

The hot-dip galvalume steel sheet is made by a kind of cold-rolled steel coil with different strength and thickness specifications as the base metal which is pre-coated by hot-plating for Al-Zn coatings on both sides and has a mass percentage of about 55% 43.5% zinc, 1.5% Si, combined with physical protection and integration of high durability and electrochemical protection features of Al and Zn to obtain the substrate metal’s strength and ductility but also corrosion resistance of the coating.It not only can protect the inner metal base from corrosion but also the surface was highly decorative bright silver gray and the regular spangle and has a bumpy sense. And this Aluzinc layers coating has very good corrosion resistance ability which offers it 2-6 times the life span versus galvanized steel coils. Developed from hot dipped zinc galvanized and hot-dipped aluminum galvanization tech, galvalume steel combines with excellent characteristics of both products, premium corrosion and oxidation resistance of hot dipped aluminum galvanization and exceptional electrochemical properties of hot dipped zinc coated galvanization, which gives galvalume steel strong anti-rust and anti-corrosion ability at the edge and on the scratched surface. The corrosion resistance property of the 55% aluminum zinc steel roll is from the aluminum layer barrier protection function and the sacrificial protection function of zinc layer. When the steel roll happens trimming, scratches and abrasions, the zinc will take the role of sacrificial coatings to protect the steel’s anti-corrosion, the aluminum will form an oxide insoluble protection barrier layer. Aluminum zinc alloy steel coil has been in a variety of different atmospheric environment, carried out more than 20 years of outdoor exposure test, it is confirmed that 55% galvanized steel roll trimming protection function is better than galvanized steel and 5% aluminum zinc steel.Main Advantage of Galvalume Steel

1. More fluent and smoother surface and superior corrosion resistance property than hot dipped zinc galvanized steel coils.

2. Excellent heat resistance durable ability and anti-oxidation performance. It can bear temperature under 315℃ without tarnish and can be applied normally under 500℃ for long period. They could reject erosion from water and mud. They are the ideal steel materials for water heating machines, food dehydrators, exhausted tubes, automobile mufflers. And its heat reflection ratio is more than 75% which is double of zinc coated galvanized steel. Heat resistance of the 55% aluminum-zinc alloy steel plate is better than that of the galvanized steel sheet, similar to the high-temperature oxidation resistance of the aluminum plate.

3. Excellent performance for coating and machinability. It is highly adhesive to organic color pre painted coatings, and it could be welded and processed as the zinc galvanized steel metals. And it could be cold bent and punching while getting beautiful outlooks. It is also cost savings as a smaller amount of base metal consuming for the same thickness, as aluminum is lighter than zinc density. It also usually gets PVDF resin to get superior chalk resistance and gloss retention as well as stain and chemical resistance. This PVDF (Poly Vinyl Irene Fluoride) is softer than polyester, making it highly formable without risk of cracking. This pretreatments and primers along with superior paint coating have increased product warranties dramatically.Industrial Applications

Galvanized Steel Supplier – Sheet & Coil

Galvanized Steel Supplier – Sheet & Coil

GRS Steel is a leading supplier of galvanized steel sheet & coil.  Galvanized steel is defined as a carbon steel sheet coated with zinc on both sides. There are two main processes used to produce galvanized steel: continuous hot dipping and electro-galvanizing.  

The hot dipping process consists of passing the steel through a bath of molten zinc, while the electro-galvanizing process consists of the application of zinc through electrolytic disposition.  The result is a layer of zinc tightly adhering to the base metal through an iron-zinc bonding layer.  Our hot dipped galvanized products are manufactured to ASTM A653 specifications; our electro galvanized products conform to ASTM A879 specifications. 

galvanized steel

A zinc coating is one of the most effective and economical methods of protecting bare steel from a corroding environment. The zinc not only serves as a barrier between the steel and the environment, but it will also sacrifice itself to protect the underlying steel sheet. Sacrificial or galvanic protection occurs when two dissimilar metals are in contact and coupled with water and oxygen. Zinc corrodes preferentially to the iron in steel. This protection prevents corrosion of the steel at areas not covered with zinc. Thus, the spread of corrosion from cut edges, drill holes, etc. is minimized.

PPGI PPGL steel coil

The prepainted steel sheet in coil is a product obtained by subjecting a hot-dipped galvanized steel sheet, an galvalume steel sheet, or an aluminum sheet to a surface chemical treatment (coating) , followed by baking and curing.

  • The total thickness of the pre-panted galvanized steel coil is composed of the base steel – coating -primer – top paint – protective layer thickness. The top paint thickness is 10-25μm, and the back paint thickness is 5-20μm. The thinner the base steel thickness, the higher the price of the ppgi steel coil, because the processing cost becomes higher.
  • Usually the paint coating material is polyester (PE) and the color of the back paint is white grey. The color can be customized according to the RAL color card or customer samples. Special patterns can be made, such as wood grain, flower print, camouflage, brick.

1) PPGI also known as prepainted galvanized steel coil and color coated steel coil, with a hot dip zinc coated steel sheet substrate.

Pre Painted Metal Coils

Coil coating has revolutionized architectural and industrial design. It is a high performance technique for applying a continuous coating to sheet metal, which results in vivid look while the base metal exhibits higher durability even in tough weathering conditions.

Advanced processing and coating techniques ensure that the coating adheres firmly to the base metal and does not peel off during roll forming, bending or any other process

Uniform thickness of the coating, extra smooth surfaces, availability in attractive colors and value for money make Manaksia’s product range truly valuable in comparison with any conventional product.

All our Units follow TQM and are ISO 9001:2000 system certified.

We currently have an operational annual production capacity of approx. 60,000MT of color-coated coils. The color-coated steel sheets & coils are available in a wide spectrum of attractive colors, styles, and gloss or matt finishes, wrinkle finishes, varying thickness of substrate & coatings.

Pre Painted Galvanized Steel Coils ( PPGI Coils )

When hot-dip galvanized steel is painted, the duplex system provides a more sophisticated manner of corrosion protection. The galvanized coating protects the base steel by providing both cathodic and barrier protection. The paint coating acts as a barrier protection for the hot-dip galvanized coating and significantly reduces the corrosion rate of the zinc.

The increased lifetime that can be provided with a combination of paint over galvanized steel makes this type of corrosion protection system very attractive for structures designed to last a long time in aggressive atmospheres.

Pre Painted Alu-Zinc Steel Coils ( PPGL Coils )

Aluzinc is cold rolled galvanized steel with metal coating composed of Aluminum (55%), Zinc (43.4%) and Silicon (1.6%). It is formable, weldable and readily accepts paint finishes. Aluzinc coated steel has superior long-term corrosion resistance in most atmospheric conditions. This is achieved through the combination of the sacrificial protection of the zinc and the barrier protection of the aluminum.

Pre Painted Aluminium Coils (PPAL Coils)

Aluminium corrosion resistance is very good in untreated aluminium. Untreated aluminium has very good corrosion resistance in most environments. This is primarily because aluminium spontaneously forms a thin but effective oxide layer that prevents further oxidation.

Pre painted Aluminium combine the metal’s anti corrosive properties along with a layer of further paint protection giving the lightweight metal a longer lifespan and a vibrant look.

What is PPGI steel coil?

PPGI is pre-painted galvanised iron, also known as pre-coated steel, coil coated steel, color coated steel etc., typically with a hot dip zinc coated steel substrate.

The term is an extension of GI which is a traditional abbreviation for Galvanized Iron. Today the term GI typically refers to essentially pure zinc (>99%) continuously hot dip coated steel, as opposed to batch dip processes. PPGI refers to factory pre-painted zinc coated steel, where the steel is painted before forming, as opposed to post painting which occurs after forming.


The hot dip metallic coating process is also used to manufacture steel sheet and coil with coatings of aluminium, or alloy coatings of zinc/aluminium, zinc/iron and zinc/aluminium/magnesium which may also be factory pre-painted. While GI may sometimes be used as a collective term for various hot dip metallic coated steels, it more precisely refers only to zinc coated steel. Similarly, PPGI may sometimes be used as a general term for a range of metallic coated steels that have been pre-painted, but more often refers more precisely to pre-painted zinc coated steel.

Zinc coated steel substrate for PPGI is typically produced on a continuous galvanizing line (CGL). The CGL may include a painting section after the hot dip galvanising section, or more commonly the metallic coated substrate in coil form is processed on a separate continuous paint line (CPL). Metallic coated steel is cleaned, pre-treated, applied with various layers of organic coatings which can be paints, vinyl dispersions, or laminates. The continuous process used to apply these coatings is often referred to as Coil Coating.

The steel thus produced in this process is a prepainted, prefinished and ready for further processing into finished products or components. to use material.

The coil coating process may be used for other substrates such as aluminium, or aluminium, stainless steel or alloy coated steel other than “pure” zinc coated steel. However, only “pure” zinc coated steel is typically referred to as PPGI. For example, PPGL may be used for pre-painted 55%Al/Zn alloy-coated steel (pre-painted GALVALUME(r) steel*)

Over 30 million tons of such coated steel is produced today in over 300 coating lines just in Boxing which is a little county in North of China.
