3105 H24 Aluminum Sheet Plate 0.5-1.2mm Roof Cladding Solar Reflective Corrosion Proof

Our 3105 H24 aluminum sheet is produced in thickness from 0.5mm to 1.2mm and width from 600mm to 1500mm for roof cladding, wall cladding and cool roof systems. Magnesium and manganese additions give it clearly better salt spray and industrial atmosphere resistance than pure aluminum, which matters for coastal warehouses, ports and chemical plants.

After coil coating, solar reflectance reaches up to 0.78, so roof surface temperature stays lower and the cooling load drops by a measurable amount. Reflectance and emissivity values are supplied for cool roof and green building submission, and the substrate is Class A non combustible for roof and wall assemblies.

The material is 100 percent recyclable and a recycled content option is available for ESG procurement. Sheets are supplied with PE film, packed on ISPM 15 pallets, and loading plans are prepared by width to raise container utilisation and lower landed cost.

3105 H24 sheet is used where a light, weather resistant and heat reflective metal skin is needed.

1. Industrial and commercial roof cladding, standing seam and corrugated roofing.
2. Wall cladding, facade lining and workshop siding.
3. Cool roof retrofit and energy efficiency projects.
4. Rain gutter, downpipe and flashing profiles.
5. Cold storage and warehouse envelope panels.
6. Coastal and port buildings exposed to salt spray.

We customize alloy, temper, thickness, slit width, coating system, gloss level and color to match your roll forming line and project specification. RAL colors, customer samples and colorimeter data can all be matched, and a pre production sample panel can be supplied for approval.

• 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 helps you select alloy and coating system according to project environment, required warranty period and forming method.

Reflectance, emissivity and salt spray data are retained per batch, so any performance question can be answered with records.

Repeat project phases keep the same coating formula and substrate source, so color matches between deliveries.

Coils and sheets are protected by PE film, secured with steel strapping and packed on ISPM 15 heat treated wooden pallets.

Wooden packaging is heat treated for EU, US and Australian customs, with corner protection for long panels.

Loading plans are prepared by width and length to maximize 20GP and 40HQ payload, with loading photos and full 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: Do you supply reflectance and emissivity data?
Yes. Coated samples are tested for solar reflectance and emissivity, and the values are supplied for cool roof and green building submission.

Q7: Is the sheet suitable for coastal projects?
Yes. 3105 with magnesium and manganese addition is salt spray tested and suitable for coastal and industrial environments.

Q8: Can you match a specific RAL color?
Yes. RAL colors, customer samples and colorimeter data can be matched, and a pre production panel can be sent for approval.
