We at Nam Kim steel joint stock company, are constantly trying to upgrade our products and improve our services to suit our customers' requirements. We have got the ISO 9001:2008 and ISO 14001:2004 Certificate. The following products standards we produce are JIS G3141/G3302/G3312/G3321/G3322 and the equivalent ones, we are pleased to introduce our Galvanized Steel Coil, Hot dip Zinc Coated Steel - GI & HGI, PPGI, GL, PPGL.
Continuous sheet galvanizing
is also a hot-dip process, but is only applied to steel sheet, strip,
and wire. A coil-to-coil process, steel sheets from 0.010 to 1.70
inches (0.25 mm to 4.30 mm) thick and up to 72 inches (1,830 mm) wide is
passed as a continuous ribbon through cleaning baths and molten zinc at
speeds up to 600 feet per minute. Preparing
the steel for the continuous galvanized coating begins with cleaning in
an alkaline liquid combined with brushing, rinsing, and drying. Then
the steel passes into the heating or annealing furnace to soften it and
impart the desired strength and formability. In this annealing furnace,
the steel is maintained under a reducing gas atmosphere, composed of
hydrogen and nitrogen, to remove any oxide that may be on the surface.
Just as in the batch hot-dip process, the steel must be completely clean
of oxides and contaminants for a successful coating.
As
the steel exits the furnace, it enters into a vacuum chamber, or snout,
before entering the molten zinc bath to prevent and air from
reoxidizing the heated steel product. The steel is then sent around a
submerged roll in the molten bath to create the bonded coating and
removed in a vertical direction. As the product is withdrawn from the
bath, precisely regulated, high-pressure air (air knife) is used to
remove any excess zinc to create a closely controlled coating thickness.
The steel is then allowed to cool and solidify before contacting
another roll to avoid transferring or damaging the coating.
How is the continuous process is used to make seven different types
galvanized (zinc)
galvannealed (90-92% zinc/8-10% iron alloy)
two alloys of zinc and aluminum (55% aluminum/45% zinc alloy and 95% zinc/5% aluminum alloy)
two aluminum based alloys (100% aluminum, 89-95% sluminum/5-11% silicon alloy)
terne coating (85-97% lead/3-15% tin alloy)
As
the name states, this process is only applied to sheet steels. The
most common applications are in car bodies, appliances, corrugated
roofing and siding, duct work, and culvert pipe. The smooth coating
does allow it to be treated for painting, which will increase service
life. Because of the relatively thin coating, unpainted continuous
sheet galvanizing is recommended for interior applications or where
exposure to corrosive elements is mild. ASTM A653 / A653M Standard Specification for Steel Sheet, Zinc-Coated (Galvanized) or Zinc-Iron Alloy-Coated (Galvannealed) by the Hot-Dip Process governs the coating of steel via the continuous process.
Coating Characteristics
Because
both are hot-dip processes, continuous sheet and batch hot-dip
galvanizing are often confused. One major difference in the two
coatings is the thickness. The continuous sheet galvanizing process has
greater control and preciseness when it comes to zinc thickness as the
air knife used after galvanizing ensures a uniform thickness across the
steel sheet. The coating is mostly unalloyed zinc, though minimal alloy
layers are present, and is ductile and able to withstand deep drawing
or bending without damage. This is important as the coating is applied
prior to final fabrication such as punching, bending, and cutting. Because
of the precise control of coating thickness, continuous sheet is
stocked in a variety of coating weights. One of the most common zinc
coatings is Class G90, which has 0.9 oz/ft2 of zinc (total both sides) or about 0.80 mils (20 μm) per side. Service life for all zinc coatings is linear to zinc th ickness;
however, because the continuous sheet coating is applied
pre-fabrication, final forming and placement often includes punching
holes, bending, cutting, etc. which creates uncoated areas. Like batch
hot-dip galvanizing, the surrounding zinc will provide cathodic
protection to these uncoated areas, but as there is much less zinc
present, best practice is to touch-up any exposed areas after
fabrication to extend service life.

Preliminary Affirmative Determination and
Imposition of Securities
Customs Act 1901– Part XVB
On 17 October 2014, I, Dale Seymour, the Commissioner of the
Anti-Dumping Commission (the Commission),nitiated an investigation into
the alleged dumping of steel reinforcing bar (rebar) exported to
Australia from the Republic of Korea (Korea), Malaysia, Singapore,
Spain, Taiwan, the Kingdom of Thailand
(Thailand) and the Republic of Turkey (Turkey), following an application lodged by OneSteel Manufacturing Pty Ltd.
The goods subject of the application are hot-rolled deformed steel
reinforcing bar whether or not in coil form, commonly identified as
rebar or debar, in various diameters up to and including 50 millimetres,
containing indentations, ribs, grooves or other deformations produced
during the rolling process. The goods covered by this application
include all steel reinforcing bar meeting the above description of the
goods regardless of the particular grade or alloy content or
coating. The following products are excluded from the goods:
• plain round bar;
• stainless steel; and
• reinforcing mesh.
The goods are currently classified to the following tariff subheadings in schedule 3 of the Customs Tariff Act 1995.
•Tariff subheading 7214.20.00 with statistical code47;
• Tariff subheading 7228.30.90 with statistical code 49;
• Tariff subheading 7213.10.00 with statistical code 42; and
• Tariff subheading 7227.90.90 with statistical code 42.
The goods, if imported from Spain under these tariff subheadings,
are subject to a general rate of duty of 5%; and the goods imported from
Korea, Malaysia, Singapore, Taiwan, Thailand and Turkey are subject to a
“free” rate of duty. A notice under subsection 269TD(4)(a) of the
Customs Act 1901 (the Act) advising that I had made a preliminary
affirmative determination was published in The Australian newspaper on
13 March 2015. In the making of that preliminary affirmative
determination, I was satisfied that there appears to be sufficient
grounds for the publication of a dumping duty notice in respect of the
goods exported to Australia from Korea, Malaysia, Singapore, Spain,
Taiwan,Thailand and Turkey. In reaching this preliminary decision, I
have had regard to the requirements of section 269TAE of the Act and am
satisfied that dumped goods appear to have caused material injury to the
Australian industry producing like goods. The preliminary analysis of
dumping margins is tabulated below. These margins were calculated under
the Act by establishing export prices under subsection 269TAB(1)(a) and
establishing normal values ascertained under either subsection 269TAC(1)
or 269TAC(2)(c) and com paring these results in accordance with
subsection 269TACB(2)(a). Margins for uncooperative exporters were
calculated under 269TAB(3).
Preliminary Affirmative Determination Report No. 264 (PAD 264) sets
out the reasons for making this preliminary determination, and has been
placed on the public record. Alternatively, it may be examined at the
Commission’s office by contacting the Case Manager on the details
provided below.
Under subsection 269TD(4)(b), I am satisfied that it is necessary
to require and take securities in order to prevent material injury
occurring to the Australian industry while the investigation continues.
The Australian Customs and Border Protection Service will require and
take securities under section 42 of the Act in respect of interim
dumping duty that may become payable in respect of the goods exported
from Korea, Malaysia, Singapore, Spain, Taiwan, Thailand and Turkey,
entered for home consumption on or after 13 March 2015. The security
that has been determined is an amount worked out in accordance with the
ad valorem duty method. The securities will be imposed in relation to
the goods exported to Australia from Korea, Malaysia, Singapore, Spain,
Taiwan, Thailand and Turkey by all exporters at the rate specified in
the above table of preliminary dumping margin assessments. Affected
parties should contact the Commission by phone 132 846 or +61 2 6213
6000 (outside Australia) or at clientsupport@adcommission.gov.au for further information regarding the actual security liability
calculation in their particular circumstance. I must report to the
Parliamentary Secretary to Minister for Industry and Science (the
Parliamentary Secretary) with final recommendations in relation to this
investigation on or by 7 May 2015. The Minister will then decide whether
to publish a dumping duty notice and, if relevant, the level of
measures to be imposed. Further, if dumped goods give rise to
retrospective notices being imposed on the goods under section 269TN of
the Act, the dumping duty notice will also include the duties to be
imposed retrospectively.
Enquiries about this notice may be directed to
the Case Manager on telephone number +61 3 9244 8268, fax number 1300
882 506 or +61 3 9244 8902

Standard Specification for Steel Sheet, 55 % Aluminum-Zinc Alloy-Coated by the HotDip Process
1. Classification of Aluminum - zinc Alloy - Coated by the Hot Dip process (Galvalume - GL)
The material is available in several designations, as follows:
- Commercial Steel—CS Types A, B, and C, - Forming Steel—FS, - Drawing Steel—DS, - High Temperature Steel—HTS, and - Structural Steel—SS. Structural steel is available in several grades based on mechanical properties. Structural Steel Grade 50 [340] is available in three classes based on tensile strength. Structural Steel Grade 80 [550] is available in two classes, based on chemistry. The product is available in several coating weights [masses] with the coating designation in accordance with this table
2. Mechanical Properties of Aluminum - zinc Alloy - Coated by the Hot Dip process (Galvalume - GL)
Many interrelated factors that affect the ability of a steel to cold form over a given radius under shop conditions. These factors include thickness, strength level, degree of restraint, relationship to rolling direction, chemistry, and base metal microstructure. Lists the suggested minimum inside radii for 90° cold bending for Structural Steels. They presuppose “hard way” bending (bend axis parallel to the rolling direction) and reasonably good shop forming practices. Where possible, the use of larger radii or “easy way” bends are recommended for improved performance. Fabricators should be aware that cracks may initiate upon bending a sheared or cold-worked edge. This is not considered to be a fault of the steel but is rather a function of the induced localized cold-work zone. Joshua
