Product Description

Product Description

Zinc - Aluminum- Magnesium Steel  

Zinc-aluminum-magnesium coating is a ternary alloy coating whose main component is zinc, and the content of aluminum and magnesium is between 1.5-8% (where the magnesium content is not less than 0.2%).

Compared with traditional coatings such as hot-dip galvanizing, galvanized aluminum, and zinc-iron alloys, zinc-aluminum-magnesium coatings have better corrosion resistance.

(1) Since the zinc-aluminum-magnesium alloy coating is relatively thin and dense, it is not easy to peel off the coating;
(2) The corrosion products will flow and wrap around the cuts, so the protection performance for cuts and defects is better;
(3) It also has good corrosion resistance in some harsh corrosive environments (such as animal husbandry, coastal areas, etc.);
(4) It can replace some stainless steel with low requirements, or be galvanized after processing, etc., which can simplify the user's processing procedures.

Steel coil measurements

The size of a steel coil is typically expressed through three main measurements; width, thickness, and length.

• Width - refers to the measurement from one edge to the other across its flattened surface. This is a vital measurement, as it determines the maximum distance between the edges of the sheet (or if the coil needs to be slit).
• Thickness - indicates the depth of each "layer" of the steel coil, or the thickness of the sheet once unrolled. Can be measured in gauges or inches.
• Length - the full length of the steel coil when completely unrolled. This is important to determine how many coils a project may need, or as an indicator of a coil's weight.
