3003 H24 2.4mm Color Coated Aluminum Sheet for Building & Construction Projects
Product Overview
Engineered for high-demand building and construction projects, our 3003 H24 2.4mm color coated aluminum sheet integrates exceptional structural strength, long-lasting weather resistance, and versatile aesthetics. As a China-based manufacturer with 20 years of export experience in aluminum products, we adhere to international quality standards (ASTM, EN, GB/T) to deliver a reliable solution for commercial, residential, and public infrastructure projects. This sheet stands out for its balanced performance—combining the lightweight advantage of aluminum with the durability required for construction scenarios, making it a preferred choice for architects, contractors, and project managers worldwide.
Core Specifications
Key Advantages for Building & Construction
1. Superior Alloy & Thickness Performance
3003 H24 Alloy: The aluminum-manganese composition delivers excellent corrosion resistance (critical for outdoor construction) and moderate strength, while the H24 temper ensures optimal formability—supporting bending, cutting, welding, and punching for complex architectural designs (e.g., curved facades, custom-shaped panels).
2.4mm Thickness: Thicker than standard 1.4mm sheets, it offers enhanced structural stability and impact resistance, making it suitable for load-bearing applications like roofing, wall cladding, and structural panels without sacrificing lightweight benefits. It reduces transportation and installation costs compared to steel or other heavy materials.
2. Durable & Weather-Resistant Coating
-
PVDF Coating: Designed for high-end construction projects, it provides ≥18 years of outdoor color retention, resisting UV radiation, fading, chalking, and chemical erosion (acid rain, coastal salt spray). Passes 1500-hour salt spray test (ASTM B117) with no rust or peeling.
-
PE Coating: Cost-effective yet reliable, offering ≥10 years of service life, ideal for interior applications or low-rise buildings. Meets 800-hour salt spray test standards.
-
Both coatings feature strong adhesion (cross-cut test: Grade 0) and scratch resistance (≥4H pencil hardness), ensuring long-term performance in high-traffic or harsh environments.
3. Aesthetic Versatility & Design Freedom
Custom colors, finishes, and sizes allow seamless integration with any architectural style—from modern minimalist skyscrapers to traditional residential complexes.
Textured or wood grain coatings mimic natural materials (wood, stone) while maintaining aluminum’s durability, eliminating the need for frequent maintenance.
Anti-fingerprint finish option keeps surfaces clean during installation and daily use, reducing post-construction cleaning costs.
4. Eco-Friendly & Cost-Efficient
100% recyclable aluminum aligns with green building standards (LEED, BREEAM), reducing environmental impact.
Lightweight design (6.48 kg/m²) lowers transportation fuel consumption and simplifies on-site installation—cutting labor time by 30% compared to heavy materials like steel or concrete.
Low maintenance requirements: No painting or rust treatment needed, reducing long-term operational costs.
5. Wide Temperature & Environment Adaptability
Withstands extreme temperatures (-40℃ to 90℃) and harsh conditions (high humidity, salt spray, UV exposure), making it suitable for diverse construction projects globally—from coastal cities to arid regions, high-altitude areas to tropical zones.

We implement a strict 7-step quality management system to ensure consistency and reliability:
-
Raw Material Inspection: High-purity 3003 aluminum ingots (GB/T 3880-2012) are tested for chemical composition and mechanical properties.
-
Cold Rolling: Precision rolling to 2.4mm thickness with uniform grain structure (thickness tolerance controlled within ±0.08mm).
-
Tempering Treatment: H24 heat treatment (annealing + partial hardening) to achieve specified tensile strength and elongation.
-
Surface Preparation: Degreasing, alkaline washing, chromating/passivation to remove impurities and enhance coating adhesion.
-
Automated Coating: Computer-controlled roller coating for PVDF/PE, ensuring uniform thickness and color consistency (color difference ΔE ≤1.0).
-
Curing: High-temperature baking (230-250℃) for coating solidification, ensuring durability.
-
Final Inspection: Dimensional accuracy, coating thickness, color matching, adhesion, corrosion resistance, and tensile strength tests—100% inspection before packaging.
Customization Options: Tailor sheet sizes, colors, finishes, and processing (cutting, bending, punching, welding) to match project drawings and requirements.
Sample Provision: Free 100mm×100mm samples (shipping cost borne by the client) for quality verification and color confirmation.
Lead Time: 10-15 days for standard orders; 20-30 days for custom orders (depending on complexity and quantity).
Shipping Terms: FOB, CIF, EXW, DDP supported; global door-to-door delivery via sea, air, or land transport.
Technical Support: Professional engineers provide installation guidelines, material compatibility advice, and after-sales consultation (24-hour response for urgent issues).
Warranty: 15-year warranty for PVDF-coated sheets; 8-year warranty for PE-coated sheets (covering coating fading, peeling, and corrosion).
Q: Is this sheet suitable for coastal areas with high salt content?
A: Yes. The 3003 alloy’s corrosion resistance and PVDF coating (1500-hour salt spray test) make it highly resistant to salt spray erosion, ideal for coastal construction projects.
Q: What is the minimum order quantity (MOQ)?
A: MOQ is 1000 kg per color; flexible MOQ for bulk long-term orders (negotiable).
Q: Can you provide fire-resistant coating?
A: Yes, we offer fire-retardant PVDF/PE coating that meets Class A fire resistance standards (GB 8624-2012), suitable for high-rise buildings and public facilities.
Q: How to ensure color consistency for large projects?
A: We use computer color matching systems and batch production—all sheets for a single project are manufactured in the same batch to ensure color uniformity (ΔE ≤1.0).
