3.3.Salt spray tests of W.R.Alstar, 55% Al-Zn and Galvanized:
	• Photo-3 shows surface appearances after salt spray test of different hot dip coated steel sheets shown in Table-2 and two kind of specimens shown below Table-2 were tested. The areas of each coated sheet affected by rust are shown in Table-3. • The results indicate that W.R.Alstar has better corrosion resistance properties than 55% Al-Zn and Galvanized.
	Table-2. Test materials
	Remarks: 1.Post treatment values relate to the tested surface 2.Test specimens are 70mm x150mm
	Table-3. The ratio of areas affected by rust after salt spray test (sealed edge)
	(Unit : %)
	Remarks: Values in the table above indicate the percentage of white rust and values in ( ) indicate the percentage of red rust
	Photo-3. Surface appearance of several coated steel sheet after salt spray test
	• Top three in above table was tested in Nisshin steel. All edges were sealed. • Bottom two in above table was tested in High polymer test and evaluation center/Japan chemical innovation institute (test no. O0-0193). One edge was not sealed.
