3003 H14 Aluminum Sheet 2-6mm Curtain Wall Facade Panel Fire Rated Class A

Our 3003 H14 aluminum sheet is produced in thickness from 2.0mm to 6.0mm and width up to 2200mm for curtain wall panels, facade cladding, column covers and soffit work. Manganese alloying gives about 20 percent higher strength than pure aluminum while keeping enough formability for folding and roll forming of large panels.

The sheet is tension leveled to better than 2mm per meter after rolling, so large modules stay flat without oil canning, and thickness tolerance is held at plus or minus 0.05mm to keep panel weight and structural calculation consistent. Class A non combustible performance is supported by a test report that can go into the building approval file.

The surface is clean and coating ready, so PVDF, polyester powder coating and anodizing AA15 all apply with even color and no orange peel. Sheets are packed with PE film, corner protection and ISPM 15 pallets for long distance shipment.

• Alloyed for facade life: 3003 keeps strength and corrosion resistance in coastal and industrial air, so panels resist pitting and streaking over the building life.
• Flatness after leveling: better than 2mm per meter flatness prevents oil canning and shadow lines on large visible panels.
• Wide plate: width up to 2200mm reduces joints and installation time on large facade modules.
• Fire documentation: Class A non combustible test report supports building approval and insurance review.
• Coating ready surface: clean, uniform substrate gives even PVDF and powder coating appearance without orange peel or color banding.
• Traceability: heat number and mill test certificate are recorded per project batch for facade warranty files.

3003 H14 plate is used where weather exposure, flatness and fire safety are all required on a visible surface.

1. Curtain wall panels, spandrel panels and facade cladding.
2. Column covers, soffit, canopy and louver blades.
3. Roof edge, fascia and rainwater goods.
4. Interior and exterior wall panels with coating or anodizing.
5. Signage and architectural feature panels.
6. Transport and equipment panels needing corrosion resistance.

We customize alloy, temper, thickness, width, length, flatness grade, coating system and color to suit your facade system and installation method. Pre production sample panels can be supplied for architect approval, and cut to size panels can be delivered with protective film and edge protection.

• Full-process manufacturer: casting, hot rolling, cold rolling, annealing, leveling, cut to size, inspection and export packing are completed inside our own plant, so plate quality and delivery are controlled by one team instead of being outsourced to several workshops.
• 26 years of aluminum processing: established in 1999 with more than 2000 employees, annual sales of USD 30-35 million and export business covering more than 60 countries.
• Stable capacity: 5000 tons of monthly output supports long term supply contracts, repeat orders and batch-to-batch consistency, with reserved production slots for regular buyers.
• In-house laboratory: direct reading spectrometer, tensile and elongation testing machine, salt spray chamber, ultrasonic inspection, thickness gauge and flatness measurement are used on every batch.
• Certified quality system: ISO 9001:2015 management system, ASTM B209 and EN 485 material standards, EN 10204 3.1 mill test certificate, SGS and TUV third party inspection accepted, factory audit welcomed.
• Engineering support: our technical team helps buyers select alloy, temper and surface treatment for their welding, bending, drawing or coating process before the order is placed.
• Fast commercial response: quotation within 24 hours, free samples in 3-5 days, 7-20 days production lead time and complete shipping documents for customs clearance.
• Export logistics: loading from Qingdao, Shanghai, Ningbo or Tianjin with optimized 20GP and 40HQ loading plans, ISPM 15 heat treated pallets and full document service.

Our team reviews panel span, fixing method and wind load requirement, then recommends thickness and temper so the panel stays flat in service.

Coating and anodizing data, batch samples and test reports are retained, so any color or flatness question on site can be answered quickly.

Repeat project phases keep the same alloy source and coating formula, so the second delivery matches the first in color and gloss.

Sheets are covered with PE film, protected by corner boards and packed on ISPM 15 heat treated wooden pallets with steel strapping.

Wooden packaging is heat treated for EU, US and Australian customs, and extra edge protection is added for long panels.

Loading plans are prepared by panel size to maximize 20GP and 40HQ payload, with loading photos and full project documents.

Q1: Are you a factory or a trading company?
We are a manufacturer with our own casting, rolling, annealing, leveling and cut to size lines in Henan, China. Buyers are welcome to visit the workshop or arrange a third party factory audit.

Q2: Can I get a free sample?
Yes. Free samples are prepared in 3-5 days and the buyer only covers the freight, so material performance and surface quality can be verified before the mass order.

Q3: What is the MOQ?
1 ton per size for regular production. Mixed sizes can be loaded in one container and trial orders are negotiable.

Q4: How is quality guaranteed?
Every batch is tested in our own laboratory and shipped with mill test certificate, mechanical property report and dimensional inspection report.

Q5: What payment terms do you accept?
T/T, L/C at sight, D/P and D/A. Other terms can be discussed for long term cooperation.

Q6: Can you provide a Class A fire test report?
Yes. A Class A non combustible test report can be supplied with the mill test certificate for building approval submission.

Q7: What is the maximum width available?
Up to 2200mm wide plate, which reduces seams on large facade modules. Custom widths are available on request.

Q8: Is the surface suitable for PVDF coating?
Yes. The sheet is supplied clean and flat, and PVDF or polyester powder coating can be arranged or applied by your coater with consistent results.
