Strata-CAT

Strata-CAT is a unique copolymer coating system for structural corrugated steel bridges (including Bridge-Plate) that provides two layers of protection. The system is based on the industry standard, ethylene acrylic acid (EAA), as used and approved for culvert systems. The base coat zinc layer provides outstanding corrosion resistance while the top coat copolymer provides superior resistance to impact, corrosion, abrasion and inorganic acid or alkali (diluted). 

Product Features

• Extends long-term life of storm sewer and culvert structures
• Delivers a strong, durable barrier between the structure and the environment
• System is chemically bonded to substrate, preventing de-lamination
• Provides excellent corrosion resistance against diluted acids, salts and alkalis
• Prevents leaching of heavy metals into water streams
• Can be applied on full or partial structural components
• Adds virtually no weight to the structure
• Patchable film if damaged in field

Typical Applications

• Culverts
• Underpasses
• Bridges

Specifications

• Total coating system thickness of 20mils (10mils per plate side)
• Available for all steel thicknesses

Relevant Standards

• Designed to meet and exceed the industry standard of 75 years as per ASTM A742/A 742M-03
