Tolerance for thickness,width,flatness and so on conform to the requirements of JIS G3302 or ASTM A653M/924M

Coil ID can be either 508mm or 610mm, maximum coil OD is 2000mm

The speicfication of ASTM Such as A653m,A924 M and so on have been updated to the latest revisions

Excellent film adhesion

The coating layer is manufactured with fine porous surfaces so as to be high in surface vitality and be very excellent in film adhesion without phosphate treatment.

Excellent corrosion resistance

The surface layer is finer and harder than electrically galvanized steel sheets by using a hot-dip coating method so as to be excellent in white rust resistance at constant temperature and humidity as well as in red rust resistance. Especially, the adhesion with paint is good so as to be very excellent in paint corrosion resistance.

Excellent powdering resistance

This is manufactured in a short time heating and long time heat treatment method so as to be very excellent in powdering resistance.

Diverse mechanical property and high formability

The passing length of heating, crack and cooling zone of furnace before coating is made longer than the existing equipment so as to secure diverse mechanical property and high formability so that diverse desires of consumers can be satisfied.

Beautiful appearance

The flatness equal to the cold rolled steel sheet was realized by completely removing unevenness in the surface layer occurring during iron-zinc alloy using a temper rolling mill of high pressure load ratio after coating. Besides, this has no spangle and has a white gray color similar to EGI so as to be very beautiful in appearance

Corrosion resistance

The improved corrosion resistance of 55% AI-Zn alloy-coated steel coils is derived from the unique combination of the barrier protection of the aluminum and the sacrificial protection of the zinc. The formation of an insoluble aluminum oxide layer provides the barrier protection while the zinc provides a sacrificial protection at cut edges, scratches and areas of coating damage. Outdoor exposure testing of 55% AI-Zn alloy-coated steel onus has been conducted for over 20 years in various atmospheric environments. This testing also demonstrated a superior cut edge protection of 55% AI-Zn alloy-coated steel sheet than the galvanized steel sheet.

Heat resistance

Similar to the aluminum coated steel sheet that can resist high temperature oxidation, 55% AI-Zn alloy-coated steel sheet demonstrates better resistance to high temperature than the galvanized steel sheet.Benlog 55% AI-Zn alloy-coated steel sheet can be used in temperatures up to 315ºC.

Heat transmission and reflectivity

55% AI-Zn alloy-coated steel coil has a high reflectivity value making it an effective barrier against heat.

Surface Treatment:

Chromate treatment,Oiled or Anti-finger print

Surface Finished:

REGULAR SPANGLE:

Regular spangle is also called normal spangle which is naturally formed without any additional treatment during galvanizing.

MINI SPANGLE:

The spangle is restrained and formed as mini spangle by reducing the lead content in the zinc liquid or by blowing the zinc powder from the equipment installed on the zinc pot.

EXTRA SMOOTH:

The mini spangle is further skin-passed to produce the extra smooth surface

Application:

Q:what can i do to polish steel or iron?
Look for buffing compound at the hardware store. Home depot lowe's od even Wal-mart/ There is a compound for steel and for iron. I t will not make iron real shinny but it will make it look good. This stuff is to be used with a buffing wheel but I have used it on rags and it work great.
Q:is tool steel reliable steel in construction of a sword?
Tool okorder.com for some ideas on stuff that tool steel can be made into.
Q:Are some firearms stainless steel coated or finished while others are all stainless?
Stainless guns are made out of stainless steel. Now there are also guns that are coated in nickel. Those are made of the usual gun steel. Stainless steel isn't really that much more expensive than normal steel when bought in large quanities.
Q:What steel type Pokémon should I choose?
Metagross would help out a lot, Excadrill id you are not doing double battles... (two of his best moves for him hit his team and are ground.. ) if you do not want to rick excadrill use a Lucario instead for hs massive damage output.
Q:How to bend stainless steel?
Hope this helps!
Q:Conductivity question for electricity through stainless steel?
Stainless Steel Conductivity
Q:What is the molar mass of Steel?
Molar Mass Steel
Q:quality of steel ..................!!?
Various ways: Carry out mechanical testing on it to see how strong it is. eg. Tensile testing, hardness testing, impact testing. Examine a cleaned up sample on the steel under a microscope to see what the steel grain structure is like and what condition it is in (hardened etc.) Or the easiest way is to ask the supplier what it is and then find a specification sheet giving you all the above information.
Q:steel and heat treating?
Go to junkyard get old leaf spring, cut out knife, start sharpening. Why waste time heat treating steel when the spring steel as already be done.
Q:Is acrylic plastic good for bath tubs or steel ?
Steel and cast iron are the premium types of tubs. Acrylic will scratch and dull if you don't use proper cleaners. If they are not installed with the proper support, they will flex and tear loose the caulking around the edges.
