Corrugated Steel Pipe

• 6" thru 138" diameters
• All gauges and corrugations
• Domestic steel annular corrugated riveted pipe

Coatings

ZINC COATED (GALVANIZED)

This has been the standard for corrugated metal pipe for over 100 years and has been used by Wyatt Resources since 1913. The steel is coated on both sides with 2 oz. per sq. ft. of surface area. This coating produces a protective layer of .0017 inch on each surface.

ALUMINIZED TYPE 2

A pure aluminum coating is applied to the bare steel instead of a galvanized coating; this produces a coating thickness of .0019 inch on each surface.

ALUMINUM PIPE

BITUMINOUS COATED

A bituminous, or asphalt coating is applied to the corrugation on steel pipe to a thickness of 1/8 inch above the crest of the corrugations.

POLYMER COATED

A polymer film coating is laminated over the galvanized coating on steel pipe to a thickness of .0010 inch on the entire surface.
