Galvanized Small Spangle Corrugated Roof Sheet Hot Dip Gauge 22 Zinc Coated


The dictionary defines “spangle” as a glittering object. When the word spangle is used to describe the surface appearance of galvanized steel sheet, it means the typical snowflake-like or six-fold star pattern that is visible to the unaided eye.


feature of galvanized sheet. Spangle size can be affected not only by the zinc chemistry and cooling rate, but also by other factors such as the smoothness of the substrate. Consistently controlling spangle formation to a specified size, and then verifying compliance, would be an extremely difficult task. For this reason, spangle size terminology is qualitative. It is defined in ASTM A653/A653M, Specification for Steel Sheet, Zinc-Coated (Galvanized) as follows:

What is Hot Dip


Hot-dip galvanization is a form of galvanization. It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 450 °C (842 °F).


Surface Finish:



NameCodeInstructions
Ordinary surfaceFAOrdinary surface
Higher finish surfaceFBSmall corrosion points, dark spots, band marks, zinc particles, passivation defects are allowed
High finish surfaceFCNo corrosion spots are allowed, but minor indentation, scratch, zinc flow ripple, minor passivation defects are allowed in a small area, and the FA surface is maintained on the other side at least

Nameother nameInstructions
No Spangle0 Spangle; Spangle Freezinc-coated steel sheet with a uniform finish in which the surface irregularities created by spangle formation are not visible to the naked eye. The finish is produced by a combination of coating bath chemistry, or cooling.
Small SpangleMinimized spanglezinc-coated steel sheet in which the grain pattern is visible to the unaided eye, and is typically smaller and less distinct than the pattern visible on regular spangle. The zinc crystal growth is arrested by special production techniques, or is inhibited by a combination of coating bath chemistry plus cooling.
Regular SpangleSimple Spanglezinc-coated steel sheet with a visible multifaceted zinc crystal structure. The cooling rate is uncontrolled, which produces a variable grain size.
