Products Description

Galvanized roofing sheet is a steel plate with a layer of zinc on the surface. Galvanized roofing sheet is commonly used economical and effective anti rust surface treatment. and it is used to prevent corrosion of metal sheet from prolonging its service life.

There are mainly five kinds of metal plate:

1. Alloying galvanized steel sheet

2. Electro galvanized steel sheet (EGS)

3. One side galvanization and double side differential galvanized steel plate

4. Alloy and composite galvanized steel sheet

5. Galvanized roofing sheet

Here we mainly introduce galvanized roofing sheet

The cold roof is immersed in the molten zinc pot to make the surface covered with zinc. The main technology is continuous galvanizing process which is sending roofing coil into the zinc bath. During the production, one important
process is finishing.

The finishing of GI roof can be achieved as follows:

(1) To improve the flatness and smoothness of the galvanized roofing sheet, and also to smooth the surface of the zinc particles to make the strip smooth, which
is particularly favorable for the future deep drawing and other applications with high precision.

(2) After finishing, the surface of the galvanized roofing sheet has certain roughness. It can improve the adhesion force of the zinc coating, and store a certain amount of oil, which is beneficial to the lubrication
of the stamping die when deep drawing.

(3) For the prepaint, the small zinc flower can still be visible through the paint layer though
the surface is controlled by small zinc spangle. Therefore, for some galvanized plates with high demand, the surface of small zinc spangle should be treated by finishing. This will make the galvanized metal sheet get a more uniform silver appearance.

(4) The lower yield point can be reduced and the yield platform can be disappearing or not too obvious. The slip line can be prevented in the subsequent
drawing or deep drawing process, and the possibility of deep drawing can be improved.

Galvanized Roofing Sheet in Ethiopia

Galvanized roofing sheet is normally used in African buildings, especially in Ethiopia. The full name is The Federal Democratic Republic of Ethiopia. It is located in the northeast of Africa. The East of Ethiopia is Djibouti and Somalia, the west is Sudan and South Sudan, the south is Kenya and North Eritrea. Ethiopia is one of the least developed countries in the world. Based on agriculture and animal husbandry, the base of industry is weak.

In 2013, the average tax rate for the import of Ethiopia was 50%.

The main exporting commodities are coffee, oil seeds, hash grass, leather and gold, import machinery, automobiles,
petroleum products, fertilizers, chemicals and so on.

The main trading partners are China, Germany, Japan, Italy, the United States, India, Saudi
Arabia and so on. The main products imported from China is GI roof. The main size is GI roof 0.19 x 900 x 2000 mm and 0.2 x 900 x 2000 mm .Usually the
quantity is very large and payment term is 100% irrevocable letter of credit. The destination port to Ethiopia for GI roof is Djibouti port. The shipping days is 32 days or 48 days depending on different shipping line. Ethiopia is the  landlocked country and they require the Ethiopia BIYA shipping company which is  requested by their government. The sea freight will be paid in the destination port, and GI roof is transferred in Djibouti.The destination port is usually COMET/GELAN/MODJO DRY PORT.

Since 1970, Ethiopia has built good cooperation and relationship with China in Economics and Military. We believe that China will always keep on the good cooperation with Ethiopia and more and more galvanized roofing sheet will be exported to Ethiopia. These two countries will create new and brilliant future.
