Aluminium Colour Coated Sheet Price

When customers ask me for the aluminium colour coated sheet price, I usually answer with another question: "What performance do you need the sheet to deliver after it leaves the container and gets installed?" In real production and export work, price is not only the LME/aluminium ingot trend. The coating system, alloy-temper selection, film thickness, colour control, and even packaging standards can move the final number significantly.

Below is a technical, buyer-friendly breakdown of what shapes pricing, which specifications matter most, and how to match a product to the correct application so you are paying for performance, not guesswork.

What determines aluminium colour coated sheet price?

1) Base metal cost: alloy and thickness

Most prepainted aluminium sheet pricing starts with the substrate: alloy + thickness + temper.

Common export alloys include:

• 1xxx (e.g., 1060): high purity, excellent formability, typically used for general cladding, panels, and insulation jacketing where strength demand is moderate.

• 3xxx (e.g., 3003, 3004, 3105): Mn alloyed, better strength than 1xxx, widely used for roofing, wall cladding, shutters, and ceiling systems.

• 5xxx (e.g., 5052): higher strength and corrosion resistance, often specified for marine/coastal projects or tougher forming requirements.

Thickness is a direct cost driver. For architectural sheets, typical thickness ranges are 0.30–1.50 mm. If your design allows a thinner gauge with proper ribbing or support spacing, the price impact is immediate.

2) Coating system: PE vs PVDF (and what you actually get)

Coating selection is often the biggest "hidden" factor behind price differences between seemingly similar sheets.

• PE (Polyester): cost-effective, good colour variety, suitable for interiors, signage, and moderate outdoor exposure.

• PVDF: premium weathering, superior colour retention and chalk resistance, preferred for exterior façades and long-life architectural envelopes.

A professional quote should specify not just "PVDF/PE," but also the resin type, topcoat thickness, and whether it is a 2-coat or 3-coat system (primer + topcoat, or primer + colour + clear coat). These details affect coil coating line settings, paint consumption, curing window, and long-term performance.

3) Paint film thickness and primer specification

Typical references you will see:

• Top coat: commonly 15–25 μm (application-dependent)

• Back coat: commonly 5–10 μm

Higher film builds, upgraded primers (especially for PVDF exterior), and tighter tolerance requirements raise cost but reduce risk of premature fading, edge corrosion, and installation complaints.

4) Surface finish, colour, and gloss control

Metallic colours, special pearls, matte low-gloss finishes, and tight colour delta requirements (for panel-to-panel consistency) usually add cost because they require:

• more careful paint batching

• stricter coil-to-coil colour management

• tighter process control during curing

If you are matching a façade to an existing building or a brand colour, expect a price difference compared with a standard RAL shade.

5) Standards, testing, and documentation

For export projects, price is affected by what the order demands in compliance and traceability, for example:

• mechanical properties (yield/UTS/elongation)

• coating adhesion (T-bend, impact)

• solvent rub (MEK)

• gloss and colour tolerance

• salt spray or humid aging requirements

From my shop-floor perspective, the more you test and document per coil or per lot, the more time and control you build into the production plan.

6) Packaging and logistics risk control

Packaging is not decoration. Sea shipments need proper anti-moisture practices:

• waterproof paper + plastic film

• desiccant when needed

• edge protectors

• strong pallets and strapping layout

Better packaging can prevent transit oxidation, scuffing, and compression marks, which protects your installed appearance and reduces claims.

Main specifications buyers should confirm (the "quote checklist")

If you want apples-to-apples price comparison, align these items across suppliers:

1. Alloy and temper: e.g., 3003-H24, 3105-H24, 5052-H32

2. Thickness and width: e.g., 0.60 mm × 1250 mm

3. Coating type: PE or PVDF, 2-coat or 3-coat

4. Film thickness: top/back (μm)

5. Surface: one-side or two-side coated, protective film type (if used)

6. Colour system: RAL/Pantone, metallic/solid, gloss range

7. Core ID / sheet size / tolerance: depends on coil vs cut-to-length

8. Quality acceptance: visual standard, allowable defects, inspection method

If your project needs product pages for quick reference, our color coated aluminium sheet options cover common architectural and industrial specifications, and our color coated aluminum coil supports coil-fed roll forming lines.

Features and advantages that justify the right price level

From production experience, the value of a well-made colour coated sheet shows up in three places: processing, installation, and years of exposure.

• Stable forming performance: correct temper and coating flexibility help avoid micro-cracks on tight bends and lock seams.

• Consistent coating cure: good cure control improves adhesion and chemical resistance, reducing scratch sensitivity during fabrication.

• Corrosion protection by system design: substrate selection + pretreatment + primer choice is what protects cut edges and fastener zones.

• Appearance uniformity: controlled gloss and colour consistency reduce "patchwork" effects on large façades.

• Lower lifecycle cost: PVDF systems can cost more upfront but often reduce repainting or replacement cycles in harsh climates.
  
  

Typical application scenarios and recommended configurations

Building envelope: roofing and wall cladding

• Preferred alloys: 3003/3105 (balanced strength and formability)

• Coating: PVDF for exterior long-term exposure; PE for budget or mild environments

• Notes: pay attention to film thickness, chalk resistance, and colour consistency for large surfaces

Ceiling, interior panels, partition systems

• Preferred alloys: 1060/3003

• Coating: PE is usually sufficient

• Notes: focus on surface cleanliness, scratch resistance, and gloss uniformity under lighting

Roller shutter, door panels, appliance panels

• Preferred alloys: 3004/3105 (often used for roll forming)

• Coating: PE or functional coatings depending on wear

• Notes: confirm T-bend requirement, impact resistance, and protective film choice

Coastal or high-corrosion industrial environments

• Preferred alloys: 5052 or well-specified 3xxx with robust pretreatment

• Coating: PVDF with upgraded primer system

• Notes: salt fog performance is a system result, not just a paint label
  
  

Practical buying insight: how to evaluate a "good" price

A competitive aluminium colour coated sheet price should come with clarity: exact alloy-temper, verified film build, and a coating system that matches the service environment. When a quote is noticeably lower than market, I recommend checking three things first: (1) actual topcoat thickness, (2) primer type and pretreatment, and (3) substrate alloy/temper substitution.

If you share your target thickness, colour, application (indoor/outdoor/coastal), and annual quantity, a supplier can propose the most cost-effective specification without sacrificing the performance that your customers will see on the building.
