Heavy Structural Steel Protection System

This advanced surface treatment system is engineered specifically for heavy structural steel frameworks operating in aggressive marine and industrial environments. Utilizing high-density polymer resins combined with zinc-rich primers, it creates an impenetrable barrier against accelerated galvanic corrosion and moisture infiltration.

The multi-layer application process ensures uniform coverage even on complex geometries, providing long-term durability under extreme conditions including salt spray, chemical exposure, and high humidity. Each layer is formulated to bond molecularly with the substrate, preventing delamination and extending service life significantly beyond conventional coatings.

Key Specifications

• Dry film thickness: 250–400 microns per coat
• Zinc content in primer: 85% by weight in dry film
• Operating temperature range: -40°C to +120°C
• Salt spray resistance: 3,000+ hours per ASTM B117
• Impact resistance: 10 Joules minimum
• Flexibility: passes 3 mm mandrel bend test
• Application method: abrasive blasting to Sa 2.5 (ISO 8501-1)
• Curing time: 24 hours at 25°C (full cure in 7 days)

Advantages Over Standard Coatings

Compared to conventional epoxy or polyurethane systems, this solution offers superior adhesion to blasted steel surfaces, exceptional resistance to cathodic disbondment, and enhanced chemical resistance against acids, alkalis, and solvents. The high-build formulation reduces the number of coats required, saving labor and material costs while achieving greater protection.

Field tests in offshore platforms and chemical processing plants have demonstrated a 40% reduction in maintenance intervals and a 60% decrease in corrosion-related failures over a five-year period. The system is fully compatible with cathodic protection systems and meets NORSOK M-501 and ISO 12944 C5-M standards.

Pricing & Availability

Pricing is based on project scope, surface area, and required coating thickness. Standard pricing starts at $18.50 per square meter for a three-coat system (primer + intermediate + topcoat). Volume discounts are available for orders exceeding 500 square meters. Lead time is typically 10–14 business days from order confirmation.

Each order includes a comprehensive technical data sheet, application guidelines, and a certificate of conformity. On-site technical support and training can be arranged for an additional fee.
