Zinc coating surface finishNormal or regular spangle This finish is obtained during normal solidification of a hot-dip zinc coating on steel, and results in the formation of a coating which exhibits either no spangle or zinc crystals of different sizes and brightness. However, the zinc appearance has no effect on either the quality or corrosion resistance of the coating.

Flattened minimized spangleThis zinc coating finish is obtained by restricting the normal zinc crystal growth followed by the application of a skin pass process.This finish is recommended for applications where a high gloss paint finish is required. It is available for zinc coatings mass up to Z275, and a maximum material thickness of 1.20 mm if passsivation is required, or a maximum thickness of 1.60 mm if passivation is not required.

Notes:- DX 51D Bending and profiling quality in ASTM is CS Type B (Commercial Steel Type B)- Hot – dip galvanized steel is produced on continuous zinc coating lines from either cold rolled (thickness range 0.27 to 2.0 mm) or hot rolled (thickness range 2.01 to 3.0 mm) steel substrate; it is produced to the requirements of EN 10327, EN 10326, EN 10142, EN 10143, ASTM A 653M (Grade 33)- EN 10327 supersedes EN 10142- Hot rolled substrate Due to the nature of the hot rolling process, surface blemishes such as surface scratches and coil breaks which may be high lighted by the zinc coating, can occur on materials with a thickness of greater than 2.01 mm. Neither of these defects will affect the functionality of the materials.- Wet storage corrosion “white rust” Normally light white staining on galvanized steel is not a reason for concern. Either under a heterogeneous film of water, or under permanent condensation, white rust appears on the surface of the steel sheets. It is a precipitation of basic salts of zinc Zn (OH)2 that combines with CO2 to form a protective layer called Zinc Hydroxycarbonate.- In case of ASTM specification, the specification of hot-dip galvanized steel sheet was unified as ASTM A653. - However the former specifications likely to ASTM A526, A527, A528 are also used.- Bending Quality of EN specification is called Lock Forming Quality (LFQ) in JIS or ASTM.

Effect of Cold WorkThe working of austenitic stainless steel significantly increases the Proof Strength. Localized cold working arises during the forming of angle and channel sections.The benefits of this cold working are not taken into account in SFSP’s designs, but provide additional reserves of strength.

ALUMINIUM

G- Aluminium 5052 & 6063Aluminium is one of the most abundant metals and therefore cost – efficient. High strength – to – weight ratio combined with extraordinary corrosion resistance and flexibility make aluminium a desirable solution to product design.

Aluminium Extrusions vs. Roll Formed SteelAluminium Extrusions Roll Formed Steel

Strength (Tensile) Very good mechanical properties Very high mechanical properties

Density Light weight: about 1/3 that of copper or steel High density; high grams per cubic centimeter.

Strength-to-Weight Ratio Very Good Good

Corrosion ResistanceExcellent it can be further increased. Along with enhanced appearance.Through anodizing or other coatings.

Fair, usually requires protective coatings for corro-sion service.

FormabilityEasily formable and extruded in a wide variety of complex shapes including multi-void hollows. Formable to net shapes, and extrusions provide for the placement of metal where it’s needed.

Readily formable; thinner cross-sections than alu-minium extrusions; metal cannot always be located where best used in design.

FinishingA huge array of finishes can be applied including mechanical and chemical prefinishes, anodic coatings, paints and electroplated finishes.

Protective coatings such as paint finishes are em-ployed along with electroplated finishes.

Recyclability High scrap value; routinely reprocessed to generate new extrusions. Low scrap value.

Pure aluminium, has little strength, but possesses high electrical conductivity, reflectivity, and corrosion resistance. For this reason, a wide variety of aluminium alloys have been developed.

Some Aluminium Alloys:5052 Aluminium 6063 Aluminium

G.1- 5052 Aluminium 5052 is the alloy most suited to forming operations, with good workability and higher strength than that of the 1100 or 3003 alloys that are commercially available.5052 has very good corrosion resistance, and can be easily welded. 5052 is not a good choice for extensive machining operations, as it has only a fair machinability rating.

G.2-6063 Aluminium 6063 is often called architectural aluminium for two reasons – first, it has a surface finish that is far smoother than the other commercially available alloys, and second, its strength is significantly less (roughly half the strength of 6061), making it suited for applications where strength is not the foremost consideration.6063 is rated “Good” for forming and cold working operations, “Excellent” for anodizing, and “Fair” for machining.

Finishes1-Hot dip galvanization (H.D.G) After FabricationISO 1461 / ASTM A 123

H.D.G process consists of dipping steel in melted zinc at 450° Celsius tempera-ture at which iron and zinc share great affinity, and allowing an alloy to form where pure zinc prevails to the outside.

Due to the difference of electrochemical potential between zinc and steel (cathodic protection), a zinc coating can protect steel in such a way that vigor-ous forces, such as cutting, scratching or piercing, are equally protected against corrosion.

What considerably affects the appearance and gauge of galvanization is the contents of alloyable elements that are generally present in steel: Carbon, magnesium, and silicon. If the contents of these elements increase, the coating gauge also increases and it becomes matte grey. The greatest effect is produced by silicon in concentrations higher than 0.12%.

Renovation Methods:Thermal zinc spraying zinc rich paints and zinc alloy stick.

Dispute:Mean masses of HDG coating per unit area using gravimetric method and nominal density of the coating (7.2 g/ cm2)

Dispute:New sample taken randomly from the lot, which has twice the % of the test articles, Magnetic thickness test the sample.

Details:Steel chemistry and surface condition determine the metallur-gical reaction between zinc and iron (steel), therefor generat-ing a range of zinc coating thicknesses.Steel containing elevated amounts of silicon and phosphorus tend to exhibit thicker coatings. It is recommended that steels have a slilicon content below 0.04% or between 0.15 % anc 0.22%, as well as a phosphorus level less thsn 0.04%.

Notes:A1: 1/4-inch thick steel has at least 3.9 mils (99 microns) of zinc coat-ing, per ASTM A 123.A2: 1/4-inch thick steel will be protected for approximately 72 years in an industrial environment before any touch-up or repair will be required to extend the life of the steel in use.B1 and B2 : 1/2-inch thick steel often has a zinc coating of four mils or more, resulting in a maintenance-free performance for approxi-mately 85 years.Cost: The initial cost of hot-dip galvanized steel is equal to the final cost,thus there are no maintenance costs from year 0 to year 72.

Replaces BS7371-3:1993

Zinc plated products have an attractive appear-ance when new as the zinc coating is bright and smooth, where a hot-dip galvanized coating has a duller and less smooth surface. There is typically about 10 times as much as zinc applied to small parts in the hot-dip galvanizing process as with zinc plating. But zinc plating will not provide adequate corrosion resistance and will rarely provide more than 12 months protection in most of the coastal population centers.

Epoxy coating powder types (EP) (5-15 μm) / InternalEP coating powders possess very good chemical resistance and excellent mechanical values such as high elasticity or impact resistance. Epoxy powders are used for corrosion – resistant applications. They have no physiologically negative characteristics. One disadvan-tage is their tendency to “ go chalky” and turn yellow under external factors

Polyester coating powder (SP) (25 μm) / ExternalPolyester coating powders are weather proof and do not “go chalky”, so they can be used out – doors. They have good mechanical properties such as blow and impact resistance and good adherence, which means that such later processes as sawing, drilling, or machin-ing are also possible.

Polyester / Epoxy coating powder (SP / EP) / Internal & ExternalThe mixing ratio between epoxy resin and polyester resin varies between 60 / 40 and 10 / 90. The resultant powder films are far more resistant to yellowing and less liable to “ go chalky”, and also have excellent mechanical qualities.The range of colours includes the whole of the standard RAL pallet and many others.
