Flat aluminum panel is the most mature, versatile and cost-effective standardized metal decorative material for modern building curtain wall decoration. Adopting national standard high-quality aluminum alloy as the substrate, the product is manufactured through integrated processes including CNC precision cutting, precision bending, stiffener reinforcement and professional surface coating. With multiple leveling and correction treatments, the panel features high flatness, square corners and straight lines without waves, warping or deformation. Different from shaped aluminum panels, flat aluminum panels focus on neat and concise facade effect with stable structure, balanced performance and excellent weather resistance. It integrates waterproof, dustproof, self-cleaning, lightweight, safe and low-maintenance advantages, and adapts to minimalist, modern, public and commercial architectural styles. It is the fundamental core material for exterior curtain walls, indoor fine decoration and renovation projects.
Flat aluminum panels usually adopt 3003 anti-rust aluminum alloy or 5052 high-strength aluminum alloy substrate with good toughness, high flatness and crack resistance, suitable for large-area wall laying. Conventional thicknesses include 1.5mm, 2.0mm, 2.5mm, 3.0mm and 4.0mm, and thickened panels can be customized according to building floor height, wind load and exterior wall span. The whole production process adopts CNC precision equipment with accurate cutting size and vertical and unified flanges. Large-size panels are equipped with galvanized stiffeners to offset thermal expansion and wind vibration, fundamentally solving the problems of bulging, shaking and warping. Customizable surface treatments include outdoor PVDF fluorocarbon coating, electrostatic powder coating, anodizing, wood grain, stone grain and matte wire drawing. The coating features strong adhesion and uniform color with excellent stain and weather resistance.

Flat & Neat High-end Appearance: With multiple leveling and correction processes, the panel achieves ultra-flat surface and square edges. Large-area installation presents a seamless, clean and grand facade effect, perfectly matching modern minimalist, light luxury and public building styles.
Strong Structural Rigidity & Anti-deformation: Equipped with standard stiffeners, large panels gain enhanced overall rigidity to resist wind pressure, thermal expansion and temperature stress, avoiding common defects such as vibration, bulging and edge warping for long-term stable performance.
All-weather Weather & Corrosion Resistance: The dense and tough high-polymer coating features strong adhesion, resisting long-term UV radiation, wind and rain erosion, sand impact and acid-base salt spray. It maintains stable performance without fading, chalking, cracking or peeling under extreme temperature changes.
Lightweight & High Safety: Lightweight and high-strength aluminum alloy greatly reduces building load compared with stone and cement panels, improving the overall seismic and wind resistance safety factor, suitable for high-rise and super high-rise new construction and renovation projects.
Strong Versatility & Ultra-high Cost Performance: With mature technology, simple structure and stable mass production, it features controllable cost and strong practicability, covering more than 90% of commercial exterior and interior decoration projects, serving as the most stable and cost-effective mainstream curtain wall material.
Self-cleaning & Low Maintenance: The flat and dense surface is not easy to accumulate dust and dirt, with excellent rain self-cleaning performance. Natural rain washing can keep the wall clean, greatly reducing manual cleaning and renovation costs.
Eco-friendly & Recyclable: Non-radioactive and free of harmful volatile substances with pollution-free production. 100% recyclable, fully complying with green building and low-carbon energy-saving standards.
Flat aluminum panels have a wide range of applications, covering public buildings, commercial buildings, civil buildings and old city renovation projects. Exterior applications: government office buildings, office buildings, schools, hospitals, bank outlets, commercial complexes, storefronts, hotel exteriors, factory facades and urban facade renewal projects. Indoor applications: large engineering ceilings, exhibition walls, subway, airport and station passages, elevator cladding, corridor walls, indoor flat decoration and office background walls. It is a universal all-purpose curtain wall material for interior and exterior building decoration.
All flat aluminum panels are precisely customized and produced with factory drawing deepening, with tiny dimensional error and unified flatness. Large-size panels are equipped with standard stiffeners to ensure finished product quality. Adopting industry-standard dry hanging assembly construction, the installation structure is stable with uniform and flat joints for a neat and unified overall facade. Full personalized customization of thickness, color, size and surface technology is supported, with professional node deepening, closing optimization and on-site technical docking. Strict multi-channel factory inspection ensures stable quality. Mass engineering orders are supported with full-process technical guidance and after-sales service to guarantee project quality.
Storage & Handling Standard: Finished panels must be stacked flat with wooden or soft cushions at the bottom. Single-point heavy pressure, vertical placement and collision are prohibited to avoid depression, scratch and deformation. The storage area shall be dry and ventilated, far away from acid-base, corrosive chemicals and humid environment.
Construction Environment: Avoid outdoor construction in severe weather such as heavy rain, strong wind, sand dust and high-temperature exposure. The base surface shall be dry, solid and free of dust and oil to ensure firm installation of keels and hangers and prevent hidden dangers of loosening, water seepage and falling off.
Standard Construction Process: Construct in strict accordance with layout numbers to ensure uniform joints and flat panels. Forcible prying and pulling are prohibited. Unauthorized adjustment of hanging points and simplified fixing procedures are not allowed to ensure uniform stress and stable overall structure.
On-site Processing Prohibition: Random on-site cutting, grinding, welding and hole opening on finished panels are forbidden to prevent coating damage, substrate corrosion, paint peeling and color difference. Local size adjustment must be completed by factory prefabrication.
Cleaning & Maintenance Rules: Clean only with clean water or neutral detergent. Strong acid, alkali and organic solvents are prohibited. Avoid hard sharp impact and scratching. Regularly check the tightness of hangers and bolts to eliminate loosening risks.
Temperature Expansion Treatment: Standard expansion joints shall be reserved for large-area wall installation to adapt to thermal expansion and contraction, effectively avoiding common construction problems such as arching, uneven gaps and edge warping caused by temperature changes.
