Type of coating		Density d/(g/cm³)	Coating form	Recommended Nominal Coating Weight/(g/m²)
type	code name
Pure zinc coating	Z	7.1	Equal thickness plating	80
		Coating Surface Structure	code name	feature
		Ordinary spangle	N	The zinc flower structure visible to the naked eye obtained by solidification of the zinc layer under natural conditions.
		Small spangle	M	Visible fine spangle structure obtained by special control method.
		Zinc free	F	The fine spangle structure invisible to the naked eye obtained by a special control method.
		Typical Application
		Pure zinc coating (Z) is one of the most commonly used coating types in manufacturing and construction. It is suitable for a range of applications where steel requires a coating that sacrifices protection to prolong the life of the article or structure. Typical applications include: Building and construction components, such as steel structures (purlins and girders); Steel frame decoration; Painted rainwater fittings; Auto parts and body panels; pipes and profiles; engineering components; Household appliances (washing machine frames and panels, cooker plates, dryers, speaker stands, etc.); Industrial products (oil pumps, oil tanks, heat exchangers, fan housings, trapezoidal profiles, cable tray systems); Electronics and agricultural machinery components.
