Galvanized Iron Sheet Cement Composite Board

Product Structural Design： The three-layer structure of the board is designed for long-term aging resistance, corrosion resistance, and deformation resistance, avoiding common problems of short-term rust, powdering, cracking, and delamination found in other wall panels on the market.The standard 9.5mm thickness is suitable for indoor and outdoor protective walls, ceilings, and partitions; thicker specifications can be customized for special applications

Hot-dip galvanized steel sheet with a durable surface layer

The surface layer uses thin steel sheet processed by hot-dip galvanizing.The zinc layer is evenly adhered to both sides of the steel sheet, isolating it from air, moisture, and acid/alkali mist corrosion.Compared to cold-dip galvanized sheets that develop rust spots after six months to two years, this sheet shows no significant rust in normal industrial environments.

Thicker galvanized versions suitable for coastal salt spray The interlocking perforated design on the sheet surface not only reinforces the composite layer but also disperses external impacts.Daily bumps only result in minor dents, preventing surface damage and core material exposure that could accelerate aging

Autoclaved High-Density Fiber Cement Long-Lasting Core Material： The core material undergoes high-temperature and high-pressure autoclaving, resulting in a completely stable internal fiber structure with no subsequent shrinkage or deformation.It exhibits excellent freeze-thaw cycle resistance, showing no delamination, cracking, or powdering after 25 freeze-thaw tests.The inorganic mineral raw materials prevent microbial and insect infestation, ensuring the boards will not rot or develop insect holes even in humid warehouses or enclosed underground environments, completely avoiding the large-scale damage and replacement issues associated with wood-based panels and gypsum boards within 10 years.The core material's A1-grade non-combustible properties remain stable throughout its lifespan, without decreasing fire resistance over time, ensuring no performance degradation when used as a firewall

Physically Locked Adhesive-Free Durable Composite Layer： Traditional adhesive-bonded composite wall panels experience adhesive aging and failure after 5-8 years, leading to large-scale delamination and detachment of the steel plate and cement core, requiring complete removal and replacement.Galvanized iron sheet cement composite board relies on perforated physical interlocking, eliminating the risk of organic adhesive aging.Its bonding strength remains stable throughout its lifespan under alternating wet and dry, hot and cold conditions, preventing delamination, fundamentally reducing the cost of overall wall renovation and demolition

Core Product Features： Ultra-low maintenance requirements, requiring only simple daily cleaning.The dense and smooth surface of the galvanized steel sheet allows for easy wiping of dust and oil stains with just water and a cloth, eliminating the need for special cleaning agents.It does not absorb moisture, fostering mold and black spots, thus eliminating the need for regular mold removal and repainting.Ordinary factory and warehouse walls require only basic cleaning once a year, compared to the need for complete repainting and renovation of ordinary calcium silicate boards every 2-3 years, significantly reducing labor, paint procurement, and maintenance costs

High resistance to external impacts, with an extremely low probability of damage and repair

Forklifts, transfer equipment, and goods constantly impact factory walls, causing ordinary lightweight wall panels to easily crack and requiring extensive repairs and replacements annually.The Galvanized iron sheet cement composite board, with its rigid-flexible structure, boasts outstanding impact resistance.Daily bumps and knocks will not cause cracks or perforations; only minor dents require no repair.Even if small areas of damage occur, only the affected area needs to be cut and replaced, eliminating the need for complete wall demolition and renovation, reducing maintenance material and labor costs by over 70%.Adaptive to temperature and humidity, eliminating seasonal cracking and repairs.Seasonal temperature differences and high humidity during the rainy season will not cause the boards to expand or contract, preventing repeated cracking at wall joints.No annual repairs are needed after completion.Dimensionally stable even in constantly damp conditions like underground tunnels and basements, preventing wall warping and deformation that could lead to ceiling collapse or tilting walls, eliminating safety hazards and repair costs caused by board deformation

Environmentally friendly and stable, with no aging or harmful substance release.Made entirely of inorganic raw materials, eliminating the problem of formaldehyde and VOCs released by organic coatings and resins over time.No irritating odors will be produced during long-term use in hospitals, office buildings, and enclosed factories.No need for periodic removal and replacement of aging boards, ensuring space safety while saving significant expenses on material replacements
