Aluzinc Steel Coil

aluzinc steel coil

Aluzinc Steel Coil is a flat carbon steel product coated on both sides with an aluminium-zinc alloy. The coating is composed of 55% aluminium, 43.4% zinc and 1.6% silicon and applied by means of a continuous hot dip galvanising process. Aluzinc Steel Coil is available in a wide range of steel grades: steels for cold forming and deep drawing applications, and structural steels.

Aluzinc Steel Coil 


The excellent corrosion resistance of Aluzinc Steel Coil is a result of the properties of its two metallic constituents: the barrier effect of the aluminium present on the surface of the coating and the sacrificial protection of zinc.

The characteristic spangled silver colour of Aluzinc Steel Coil gives it a very attractive appearance. Thanks to a thin transparent layer of aluminium oxide on the top surface of the coating, this appearance is preserved over time.

Aluzinc Steel Coil 

Aluzinc Steel Coil offers additional advantages:

Good corrosion resistance at high temperatures

Good abrasion resistance because of its surface hardness Excellent thermal and light reflectivity

Applications Aluzinc Steel Coil coated steels are used widely in both indoor and outdoor applications: Construction: roofing, cladding, structural sections, composite panels, tiles etc Domestic appliances: washing machines, tumble dryers, refrigerators, toasters, microwave ovens etc Miscellaneous: boiler casings, air ducts, electrical cabinets, lighting, computer casings etc Aluzinc Steel Coil can be supplied oiled and/or with a chemical surface treatment, or with an AFP thin organic coating (please see data sheet E80 for the specific properties of AFP). DX56D AM FCE +AZHFX +AFPis suitable for standing seam applications in roofing and cladding.

Aluzinc Steel Coil


Aluzinc Steel Coil Florelis is a product with improved uniformity, with the result that there is no visible difference between the sheets. It is specially designed for facades of buildings with the highest aesthetic requirements.

Recommendations for use Storage

Aluzinc Steel Coil is supplied passivated or oiled to temporarily limit any risk of black rust formation. During transport and storage, all necessary precautions must be taken to keep the material dry and to prevent the formation of condensation. Improved protection can be obtained by the application of an AFP coating.

Forming and joining

The forming and joining techniques currently used for uncoated steel sheets are also suitable for Aluzinc Steel Coil The coating thickness must therefore be compatible with both the desired degree of corrosion protection and the requirements of the forming and welding processes envisaged. Forming performance is improved if Aluzinc Steel Coil is coated with an AFP thin organic coating.

Aluzinc Steel Coil Roofing

Painting Aluzinc Steel Coil can be painted after degreasing and surface treatment when delivered oiled. Aluzinc Steel Coil coated with an AFP thin organic coating can be painted directly, without any prior surface treatment. However, the paint must be compatible with the AFP resin.


In electrical resistance welding, the welding current must be suitably regulated and regularly adjusted. Electrode life can be extended by regularly stepping up the welding current and periodically dressing (machining) the electrodes.

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.

galvalume steel coils

Galvalume Steel Coil 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.

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

2. Galvalume Steel Coil 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. Galvalume Steel Coil 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.

Our experience in the field means that we approach each project with the same dedication and determination, and the three-step process our cold rolled steel sheet in coils are treated with (as detailed below) makes sure that each and every one of our steel coils is durable and dependable for the long haul.

What is Cold Rolling?

cold rolled steel coil

Cold rolling is the process whereby steel is treated below its recrystallization temperature which is versus to hot rolled steel to produce uniform, flat steel coils. Not only does this compress the thickness of the material, but it also boosts tolerance, improves tensile strength, and smooths surface finishing by hardening the inner strains of the metal. The cold rolling process results in an estimated 20% improvement in overall steel strength, so it’s easy to see why cold rolling is coming into higher and higher demand among industry professionals, engineering firms, and product designers.

Cold Rolled High-Quality Carbon Structure Steel Strip

​Our cold rolled steel coils undergo a thorough picking process on a continuous picking line that removes any and all mill scale from the steel. This produces a clean surface prior to cold rolling so that the end result is a strong and durable material with a high-quality surface.​Today, Cold rolled steel Coil is used in products that span the whole of human industry, from metal desks and filing cabinets to motorcycle exhaust pipes, from fan blades and frying pans to computer cabinets and components. No matter what line of business your company specializes in, it is likely that you use cold rolled steel. Sinowell Metal offers the highest quality cold rolled steel coils at the most competitive prices. The professionals at Sinowell Metal have the experience and the expertise necessary to custom design cold rolled steel coils to accommodate your needs.

Cold Rolling Dual Phase Steel Coil


After the cold rolling process has been completed, we use annealing to make our steel coils extra workable. Annealing involves heating the metal above its recrystallization temperature and then cooling it back down again. This resettles the microstructure of the steel, improves the mechanical properties of the metal, and relieves the internal stresses that build up during cold rolling. The annealing process means that our steel coils are especially customizable and can be easily worked to meet the specifications of the project at hand. This is only the second stage of our three-step process: now that the metal has been made more elastic, we need to toughen it back up again.


Once the metal has been annealed, we put it through a multi-stage tempering process that uses light pressure to flatten the steel so that our premium surface finish can be applied. This ensures that the metal not only looks good, but avoids the stretcher strains that tend to occur during forming and deep drawing.

Cold Rolled Strength Low Alloy Steel Coil

Our tempering process uses precise instrumentation and detailed supervision to achieve just the right elemental balance in each and every steel product we make. We subject all of our products to the same process and the same meticulous quality inspection each time, every time. The end result is a steel coil that you can depend on, one that is strong, malleable, and resistant to wear and tear.

steel coil for producing Corrugated Galvanized roof sheet 

The cladding elements are manufactured from coils of coated Corrugated Galvanized Roof Sheet or stainless Corrugated Galvanized roof sheet. The sheet is uncoiled, flattened and sheared length wise. Then, it is cold processed on a roll- forming,panel bending line. The elem ents are then stacked and packaged attheend of the manufacturing line. The adhesion of the zinc to the base metal (iron- zinccom bination) occurs during the continuous galvanization process and guarantees increased resistance to corrosion,and so does the cathode protection provided by the zinc.

Iron- zinc cathode protection checks the spread of rust on the sheared edgesorin the fixing holes via a transfer of zinc by electrolysis.An important feature ofm etallic coated Corrugated Galvanized roof sheet on a continuous process is that it is rust- resisting,not only on the zinc coated sides but also w hen cut. In use of non prepainted galvanised Corrugated Galvanized roof sheet should there be any efflorescent (white rust) caused by a deposit of hydrated zinc oxide, zinc hydro carbonate or zinc oxychloride, it w ill not alter the mechanical properties of the profiles Corrugated Galvanized roof sheet sheeting.The galvanised Corrugated Galvanized roof sheet sheets are passivated in a chromium VI- free chemical solution in order to resist against white rust during the transport and the storage.Depending the manufacturing,a whitening discoloration could occurs. This phenomenon does not modify the properties of the material.In prepainted Corrugated Galvanized roof sheet,small scratches are protected by zinc.Even though we recommend to retouch with an appropriated paint. Highly elaborated techniques are used to manufacture Arval by Baosen Corrugated Galvanized roof sheet Construction pre- painted Corrugated Galvanized roof sheet,which have solved m any painting problem s, thus giving a high performance product.

For more than a quarter of a century, ZINCALUME Steel has demonstrated its outstanding resistance to atmospheric corrosion. This protection against corrosion, which is remarkable for an exclusively metallic coating, is the result of the combined action of aluminium and zinc. The aluminium protects the steel substrate, creating a shield between the surface and the atmosphere. This aluminium barrier is very stable, as the aluminium oxide coating that forms on the surface is insoluble in most environments, thus ensuring a long-lasting resistance to corrosion. The zinc provides the same protection as it does for galvanised steels whenever the steel substrate is exposed (e.g. by accidental cuts or scratches). In practice, the zinc corrodes instead of the steel, a phenomenon known as sacrificial cathodic protection. The combined effect of these two protective mechanisms ensures that ZINCALUME Steel performs better than steel sheets protected with either pure zinc or pure aluminium.
