Nano Galvalume Steel Sheet| Heat Insulation & Anti-Corrosion Manufacturer

Over 10 years of foreign trade experience, proficient in international compliance and risk control.

Source factory, no middlemen. Factory-direct sales, remarkable price advantages. Customization available, controllable delivery lead time.

 Excellent thermal insulation and cooling: With high thermal reflectivity, it effectively blocks external heat, reducing indoor temperatures by 8-10°C compared to outdoor conditions when applied to roofs in summer.
 Outstanding corrosion and acid resistance: The special nano-coating on the surface provides superior resistance to acids and alkalis, surpassing that of ordinary PPGI/PPGL steel plates.
 Easy installation and cost-effective: Compatible with common accessories such as screws and nuts, the installation process aligns with standard pre-painted steel roof panels, enabling shortened construction timelines and reduced project costs.
 Wind-resistant structural safety: All components are rigidly connected, ensuring a stable structure capable of withstanding severe typhoons, providing safe and reliable operation.
 Lightweight design reduces construction difficulty: The lightweight design of the panels can lower the load-bearing requirements of steel structures, thereby reducing construction complexity.
 Long-lasting durability: The coating, prepared through specialized processes, boasts superior thickness compared to conventional paint finishes, ensuring a longer product lifespan.

 Substrate & anti-corrosion performance

Regular color-coated galvanized steel uses a pure zinc substrate with sacrificial anode protection; cut edges and minor coating scratches easily cause rust creep. Our nano galvalume steel sheet features a 55% Al-Zn alloy base plus a nano-scale pore-sealing layer, delivering 3–6 times higher corrosion resistance, especially reliable for coastal and industrial corrosive scenarios.

 Heat insulation & high-temperature resistance

Standard color-coated steel absorbs most solar infrared radiation with barely any thermal insulation effect, and supports continuous service at up to 230°C. Our product reflects over 75% of infrared rays, reducing indoor temperature by 8–10°C in summer, with a sustained temperature tolerance up to 315°C.

 Coating durability & formability

Conventional organic topcoats are prone to chalking, peeling and cracking during roll forming. The nano functional coating has a dense structure and strong substrate adhesion, retaining full integrity after deep processing and resisting surface abrasion.

 Pricing & lifecycle cost

The unit price of our nano galvalume steel sheet is slightly higher than regular color-coated galvanized steel, but its service life is over 3 times longer with minimal maintenance required, cutting total full-lifecycle cost by roughly 30% for long-term construction and industrial projects.

 Exterior applications

Widely used for roof panels, photovoltaic roofing systems, anti-corrosion insulated steel tiles, wall cladding, aluminum curtain walls, honeycomb panels, corrugated panels, modular prefab houses, sandwich panels, outdoor railings, awnings, garage doors, rolling shutters, advertising signs, light boxes, aluminum drainage systems and other construction metal components.

 Interior applications

Applied to cabinet doors, furniture doors, fire doors, indoor doors, medical doors, wall panels, metal railings, elevator cabs, ceilings, display racks, office furniture, home appliance panels, water heaters, air conditioner housings, lamp shades and other decorative metal products.

Standard Packaging: Waterproof paper + steel strip fixing + wooden pallet, ensuring safe transportation.
