Specialized Pipe Supports
Sunrise has been directly licensed with ANVIL International to sell expanded products in ANVIL. Anvil Pipe Hangers and Supports are manufactured in three primary U.S. locations: North Kingstown, Rhode Island’ Henderson, Tennessee and Columbia, Pennsylvania, each with its own unique capabilities.
Anvil offers 3 basic forms to zinc coating on its hanger components as given below:
Electro-Plated Zinc (ASTM B633)
This type of coating is recommended for use indoors in relatively dry areas. The steel is submersed in a bath of zinc salts, through the process of electrolysis, is a coating of pure zinc adheres to the steel with a molecular bond. A maximum of .2 mills of zinc can be applied using this method. The threaded components and fasteners for Anvil hangers are furnished electroplated.
Pre-Galvanized Zinc (ASTM B653)
This type of coating is suitable for extended exposure in dry or mildly corrosive atmospheres, but not generally recommended for use outdoors in industrial environments. Also known as “mill galvanized” or “hot-dipped mill galvanized”. Pre-galvanized zinc coatings are produced by rolling the steel coils or sheets through molten zinc at the steel mill. The material is then cut or slit to size. Coating thickness is 90 ounces per square foot of steel surface. Zinc near the uncoated edges or weld areas becomes a sacrificial anode which protects the bare areas. Anvil uses this type of material on our shields and swivel ring hangers.
Hot-Dip Galvanized (ASTM 123)
Recommended for prolonged outdoor exposure and will usually protect steel in most atmospheric environments. After fabrication, the part is immersed in a bath of molten zinc. A metallurgical bond is formed, resulting in a zinc coating that coats all surfaces including edges.
