Coloured Prepainted Galvalume Steel Coil And Sheets Full hard JIS G 3318
The production of Prepainted Galvalume Steel Coil is almost the same with Prepainted Galvanized Steel Coil which difference is only the base metal. The base metal for PPGL is GL. Galvalume is the result of an ideal alloy of aluminum and zinc. It consists of aluminum(55%), zinc(43.4%), and silicone(1.6%).
Characteristics of Galvalume:
1) Corrosion resistence:
At verious enviromental conditions, GL shows better corrosion resistence than GI if the thickness is same, its service life is 2 to 6 times than ordinary galvanized steel. The corrosion resistence in the machining parts is much better than that of hot-dip galvanized due to micro cracks demormation parts of aluminum zinc plate is smaller than hot-dip galvanized.
2) Heat resistence:
GL plate can be used for a long time even if under 315℃.
3) Heat reflective
The reflection coefficient is double than that of hot-dip galvanized steel, which can reduce the inner tempeture in summer.
2. Performance Of Antistatic PPGI/PPGL
1) Its machining property and durability match that of the PPGI with common polyester as its base metal.
2) Its resistance to chemicals and solvents is slightly higher than that of PPGI with common polyester
3) Its surface resistance (Ω/cm2) is 106-109Ω (PPGI with common polyester: 1013Ω )
3. Air exposure test for PPGI and PPGL
Principle: Assess the loss of gloss, color change, chalking, foaming, rusting, cracking and other aging features of the coating membrane after the prepainted steel sheet aged for being exposed in the air.
Result: 1. For the flat-sheet sample, assess the frade in loss of gloss, color change, chalking, foaming, rusting, cracking, etc. by the GB/T 1766 standard, and take the worst result as the final.
2. For the sample of destroyed steel sheet, assess the grade of all parts bended in T shape, shocked, scratched, riveted or curved in forming, rusting and outreach of corrosion, etc. by the GB/T 1766 standard, and take the worst result as the final
3. This test can also be performed by other labs of air exposure, and it is required that the lab should submit the relevant test report.
