Coated steel sheets for ship interiors are specialized composite materials designed for the unique environments of ships, including high humidity, high salt spray, and confined spaces. They use marine-grade galvanized steel sheets, zinc-aluminized steel sheets, or stainless steel sheets as the base material, laminated with a weather-resistant polymer film (PVC, PET, or modified fluorocarbon film). A thermal bonding process achieves a tight bond between the base material and the film. The core performance fully meets the stringent requirements of ship interiors, specifically:
Corrosion Resistance
The coating completely isolates the steel from corrosive media such as moisture, salt, acids, and alkalis. The base material undergoes marine-grade anti-corrosion treatment, achieving a salt spray resistance of over 1000 hours. This effectively resists salt spray corrosion in ship cabins and coastal and open-ocean environments, preventing steel plate rust and extending the material’s service life.
Fire-retardant and flame-retardant standards met
Strictly compliant with the IMO SOLAS Convention and the fire-resistant standards of major classification societies such as CCS, LR, and BV, the coating uses a flame-retardant formula, releasing no toxic gases during combustion and exhibiting excellent fire-resistant properties. It meets the fire-resistance requirements of various areas on board ships, including passenger cabins, corridors, and galleys, ensuring navigational safety.
Moisture and heat resistance and weather resistance
It can withstand a wide temperature range of -30℃ to 80℃ in ship cabins, as well as long-term high-humidity environments. The coating layer will not soften, deform, or crack due to alternating hot and cold temperatures, nor will it mold or peel due to moisture. It also has UV resistance, preventing fading and aging caused by sunlight exposure.
Easy to clean and stain-resistant
The smooth and hydrophobic surface of the coating makes it difficult for oil, water stains, dust, and other contaminants to adhere. Cleaning is as simple as wiping with a damp cloth, eliminating the need for strong cleaning agents. It is especially suitable for easily soiled areas such as galleys, restrooms, and dining areas, resulting in low maintenance costs.
Structural Strength and Processability
The metal substrate provides excellent tensile strength and rigidity, meeting the structural requirements of ship interiors for wall panels, partitions, and door panels, and is not easily deformed. It also possesses good processability, allowing for stamping, bending, and cutting. The coating is resistant to peeling and wrinkling during processing, adapting to complex interior design needs.
Environmentally Friendly, Safe, and Odorless
Using marine-grade environmentally friendly adhesives and coating materials, it contains no formaldehyde, heavy metals, or other harmful substances, meeting the “low VOC” requirements for ship interiors. There is no odor release during use, ensuring a healthy living environment for crew and passengers. Furthermore, the materials are recyclable, aligning with the trend of green ship development.
Ease of Installation
Supports modular prefabrication installation, allowing for on-site assembly after factory prefabrication. Installation is fast and efficient, effectively shortening the ship interior construction period. It also has low requirements for the construction environment, reducing on-site construction pollution.
