Introduction: Meeting the Extreme Demands of Port Environments

Portal cranes operate at the interface of land and sea, exposed to salt spray, wave splash, industrial pollutants, and constant weather cycling. These conditions create some of the most aggressive corrosion environments in industry. FLD’s marine-grade epoxy coating for portal crane structures provides protection engineered specifically for these challenging conditions.

Core Benefits

Marine Atmosphere Protection

Our coating resists salt spray, chloride ions, and humidity cycles that rapidly degrade conventional coatings.

Splash and Immersion Tolerance

Areas subject to wave splash receive protection equivalent to immersion-grade coatings, preventing localized corrosion failure.

Structural Integrity Preservation

Prevents corrosion-induced section loss that reduces crane load capacity and service life.

Regulatory Compliance

Meets maritime safety standards and port authority specifications for crane structure protection.

Key Features

Epoxy-Polyurethane System

Epoxy primer and intermediate coats provide corrosion protection; polyurethane topcoat delivers UV resistance and aesthetics.

High Build Application

Thick-film system (300-500 microns total) provides robust barrier protection with fewer application coats.

Excellent Adhesion

Penetrates surface profile and bonds permanently to steel, maintaining protection under structural flexure.

Low Temperature Cure

Can be applied and cured at temperatures as low as 5°C, extending maintenance windows.

Application Areas

• Boom and jib structures
• Portal frame and legs
• Slewing platform
