This photo shows our PPGL coil to Dominican, you can see the painting thickness is 42μm, which is higher than client's requirement.

Characteristic

Examples of products in practical application are as follows:

Base plate selection: az150 (aluminum zinc plating amount 150g / m2) G345a high strength aluminum zinc plated steel plate (55% aluminum, 43% zinc and 1.6% silicon)

Corrosion resistance data: 5% NaCl 35 ℃, 1000hrs, good field, scribe no blister less than 2mm

Q. At U.V.: 2000hrs, the color difference is max.2, and the light retention rate is more than 90%

The above data show that the aluminum zinc color coated plate (az150, g345a, PVDF) is very suitable for buildings or other facilities in extreme environments, with great corrosion resistance and weather resistance, and the major steel mills of this kind of steel plate can guarantee the service life of more than 20 years. In addition, high-strength steel plate has been widely used abroad, which has good economy and is also the development trend in China.

This photo shows part of our PPGL workshop, you can see the finished PPGL coils in this photo, and another side is our PPGL production line.

Our PPGL coils well packed with standard seaworthy packing: kraft paper, plastic bage to prevent water and dust, the outside is metal sheets and fasten with steel strip.

Economy

The base plate adopts galvanized 100g / m2 (Z100) and aluminized zinc 70g / m2 (AZ70) for comparison:

Note: the density of aluminum zinc alloy is 3.72 and the density of zinc is 7.12 (g / cm3)

It can be seen from the above that the thickness of 70g aluminum zinc plated single-sided coating is greater than 100g zinc plated, and the special structure of aluminum zinc alloy provides better durability. In addition, on the premise of superior durability and under the condition of the same weight, the length of 1 ton of aluminized zinc color coated plate is greater than that of galvanized color coated plate, so it has better economy.
