Description of Aluminum Zinc Rolled Coil
Aluminum zinc coils is a kind of coated steel coil/sheet. With the cold rolled steel of different strength and thickness as substrate, it is produced through applying Al-Zn coat on both faces by hot dip process. In its coating, Al accounts for about 55%, Si 1.6%, while the remaining is Zn. Aluminum zinc coils enjoys both the physical protective feature and durability of Al and the electrochemical protective property of Zn. And its surface has bright silver color and regular embossed-like figure, which are highly decorative.
Main Feature of Aluminum Zinc Rolled Coil for Construction Roof

- Q:what do we use steel for and whyand why do we use brass for instrumentsplz help its homework and i cant find the answer anywhere : (
- By instruments do you mean musical instruments? Brass is used for musical instruments because it's strong but very malleable. It's easy to hammer and roll into sheets, or form into tubes and complex shapes. It's easy to work with using hand tools. It's also very corrosion resistant and polishes very well. It has an attractive gold-like color. It also has some effect on sound, though the shape and design of an instrument is much more important to the sound than the material that's used. Apart from musical instruments, brass is used for items that need to be both durable, easy to manufacture, and resistant to the elements. For example plumbing items like valves and screw couplings.brass is a lot easier to cut with machine tools than steel. It's also traditionally used for hardware on doors and cabinets because of it's color, low friction properties, and corrosion resistance. Brass also is toxic to bacteria, and so brass doorknobs disinfect themselves after about 9 hours. Steel is very strong and very cheap. Steel is basically iron with a small amount of carbon added which makes it much stronger. Iron is the fourth most common element in the earth's crust, after oxygen, silicon, and aluminum. Brass being a mixture (an alloy) of copper and zinc, with other metals sometimes added. Copper and zinc are the 27'th and 26'th most common elements. Therefore, it make sense that brass is much more expensive than steel. Steel is used for too many things to be listed. The use of steel technology has impacts on almost every aspect of modern life. Nearly all of the man-made objects you touch on a regular basis were made using steel tools and steel machinery.

- Q:I have a steel garage, it looks worn out hauled away? How can I maintain / repair it?
- Maintaining Your Steel Garage: # Clean your garage doors with a mild detergent using a soft car brush four times a year. # Clean the doors whenever they wash you car (washing your garage doors regularly will reduce the build up of corrosive elements) #Avoid using any abrasive cleaners or corrosive chemicals on or around your garage doors. # Avoid using salt near the garage door as it may corrode the door elements / hardware. Or you can paint your steel garage: #Step 1 Clean the door using a low-pressure sprayer. Combine 5 gallons of warm water and 1 cup of low-phosphate detergent to clean the surface. Rinse well and dry the surface. #Step 2 Lightly sand and smooth the scratches which do not go through to the metal substrate. Dust off sand residue. For a door with a baked on finish, use a powdered cleanser (diluted with water) and a soft brush to rough up the surface for better paint adhesion; do not use sand paper. Rinse with water and allow it to dry. #Step 3 Apply primer to areas where scratches permeate to the metal substrate to avoid future rusting or corrosion. Allow it to dry. #Step 4 Paint the door with an even coat of latex exterior house paint. If your steel garage has a dent check out the site(the last source link at the bottom)
