3003 H24 Wood Grain Color Coating Aluminium Stripe For Shutter Windows

3003 H24 Wood Grain Aluminum Strip for Shutter Slats

3003 H24 wood grain aluminum strip is a prefinished narrow aluminum material designed for shutter slats, louver windows, venetian blind components and architectural shading products. It combines a formable aluminum-manganese substrate with a decorative wood-effect surface for manufacturers requiring a timber-style appearance without using solid wood slats.

The current product range covers 0.3–2.0mm thickness and 10–100mm slit width, with common widths including 20mm, 30mm and 40mm. Custom slit dimensions can be produced according to the finished slat profile, edge-folding allowance and downstream forming equipment.

Oak, walnut, pine and other wood-grain effects can be developed according to approved samples. The final surface system, coating build and weathering requirement should be selected according to whether the finished shutter is installed indoors, outdoors or in a humid or coastal environment.

Technical Specifications

Why Use 3003 H24 Aluminum for Shutter Components?

AA3003 is an aluminum-manganese alloy widely used where moderate strength, corrosion resistance and forming capability are required. H24 temper provides a semi-hard condition suitable for compatible bending, slitting and profile-forming operations.

The material properties of 3003 H24 vary with thickness and applicable material standard, so mechanical-property limits should be stated in the purchase specification rather than assumed from one universal value.

Formability for Slat Processing

Shutter and louver components can require bending, edge curling, profiling or roll forming. Aluminum alloy, temper, thickness, bend radius and coating flexibility should therefore be evaluated together.

Corrosion Resistance

3003 aluminum provides useful inherent corrosion resistance for architectural components. For outdoor or coastal use, however, long-term performance also depends on pretreatment, primer, decorative coating, cut-edge condition and maintenance.

Low Material Weight

Aluminum has a density of approximately 2.7g/cm³, allowing lightweight slat and shutter components compared with many steel-based alternatives.

Wood Grain Surface System

Thermal-Transfer Wood Grain

The decorative surface is produced using a wood-grain transfer process over a compatible prepared coating system. Oak, walnut, pine and other patterns can reproduce the visual character of timber while retaining an aluminum substrate.

Pattern Consistency

For long shutter runs or multiple window units installed on the same elevation, pattern, color and gloss consistency should be controlled between production batches.

A physical approved sample is recommended where color matching is critical.

Coating Adhesion

The decorative system must remain adequately bonded during slitting and downstream forming. Where severe bends or edge curls are required, representative material should be tested using the customer's actual tooling.

Outdoor Weathering Requirements

Outdoor shutters are exposed to sunlight, humidity, temperature cycling, rain and airborne contaminants. The required coating specification should therefore be based on the actual installation environment.

UV Exposure

Where long-term exterior color retention is required, the customer should specify the applicable accelerated-weathering method, exposure duration and acceptable color or gloss change.

Weathering-test hours should not be converted directly into a guaranteed number of outdoor service years unless a validated correlation exists for the exact coating system and environment.

Salt-Spray Exposure

For coastal or chloride-bearing environments, an enhanced pretreatment and coating system can be discussed together with an agreed salt-spray test requirement.

Where a 1000-hour-class test is requested, the test method, scribe condition and acceptance criteria should be stated in the purchase specification.

Humidity Resistance

Aluminum does not absorb moisture and swell in the same manner as natural timber, making coated aluminum a practical material for selected bathroom, kitchen, balcony and other humid-space shutter components.

Condensation, cut edges and hardware compatibility should still be considered in the completed shutter system.

Precision Slitting for Shutter Manufacturers

Narrow-strip dimensional consistency is important for automatic feeding, profiling and assembly. Strip width should match the finished slat geometry together with any edge-forming or folding allowance.

10–100mm Custom Slit Width

The current range is 10–100mm, with 20mm, 30mm and 40mm as common reference widths. Customized slit widths can be produced according to the manufacturing drawing.

Edge Quality

Slit edges should be controlled for excessive burrs, distortion and coating damage that could interfere with feeding or downstream forming.

Width Tolerance

The current page references a width tolerance of ±0.1mm. For high-speed profile lines, customers should confirm whether this tolerance matches their feeder and roll-forming requirements.

Roll Forming and Bending

Bend Radius

The minimum practical bend radius depends on substrate thickness, temper, coating construction and forming direction.

Tight bends should be tested before recurring production because a bend that is acceptable for the aluminum substrate may still place excessive strain on the decorative coating.

Edge Curling

Where shutter slats use curled or folded edges, the forming sequence should be evaluated for cracking, coating damage and dimensional stability.

Roll-Forming Line Compatibility

Manufacturers should provide strip feed width, thickness, profile drawing, number of forming stations and minimum bend radius where possible.

This allows the raw-material specification to be matched more accurately to the intended shutter component.

Roller Shutter Feed Width Considerations

Roller-shutter profiles can require wider feed strip than the current 10–100mm standard range, depending on the finished slat width and profile geometry.

If the material will be used for a wide roller-shutter slat rather than a narrow shutter or louver component, provide the finished profile drawing and required feed width before ordering.

This helps determine whether the requested profile can be produced within the available slitting range or requires a different master-coil configuration.

Typical Applications

Shutter Window Slats

Wood-grain aluminum strip can be formed into suitable decorative shutter-window components for residential and commercial buildings.

Louvered Window Components

Narrow strip can be used for compatible fixed or adjustable louver components where a lightweight metallic substrate and wood-style finish are required.

Venetian Blind Components

Custom slit widths can support suitable Venetian blind and architectural shading components where consistent strip dimensions and decorative appearance are important.

Architectural Sunshades

The material can be evaluated for decorative shading strips, balcony screens, ventilation elements and similar architectural components.

Bathroom and Kitchen Shutters

Coated aluminum is suitable for selected humid interior environments where natural timber swelling or moisture absorption is undesirable.

Exterior Shutter Systems

Outdoor use can be considered with an appropriately specified pretreatment and coating system. Wind resistance, maximum shutter dimensions and structural performance must be evaluated on the complete shutter assembly rather than the raw aluminum strip alone.

Wood Grain Aluminum vs Other Shutter Materials

Mechanical Property Specification

Mechanical properties of 3003 H24 vary according to thickness and applicable material specification. For this reason, tensile strength, proof strength and elongation should be agreed for the actual ordered gauge rather than using one fixed value across the entire 0.3–2.0mm range.

Where mechanical values are contract-critical, the purchase specification should state the applicable aluminum standard, test direction and required minimum or range for tensile strength, proof strength and elongation.

Coating Performance Requirements

Wood-grain coating performance should be defined using measurable test methods rather than only descriptive terms such as weather-resistant or scratch-resistant.

Quality Control for Wood Grain Aluminum Strip

Alloy and Temper

The aluminum substrate should be checked against the agreed AA3003 H24 material specification.

Thickness

Strip thickness should be measured against the ordered gauge and tolerance because gauge variation can influence stiffness and forming behavior.

Slit Width

Finished strip width should be checked along the coil to support stable automatic feeding and consistent profile geometry.

Slit Edge Quality

Edges should be inspected for excessive burrs, waves and damage that could affect roll forming or assembly.

Wood Grain Appearance

Pattern, tone, gloss and visual consistency should be compared against the approved production standard.

Coating Adhesion

Coating adhesion should be verified according to the agreed test method, particularly where the strip undergoes post-coating bending.

Forming Trial

Representative strip should be tested on the intended forming process where the product uses tight bends, edge curls or multiple roll-forming stations.

Sample and Forming Trial

Sample evaluation is recommended before commercial production when introducing a new slat profile, strip width, thickness, wood-grain pattern or coating system.

The trial can verify feeding, slitting accuracy, bend performance, edge curling, coating adhesion, pattern appearance and dimensional stability after forming.

After approval, the alloy, temper, gauge, feed width, surface structure, wood pattern and inspection requirements can be retained as the repeat-order specification.

Packaging and Export Supply

Wood-grain aluminum strip can be protected with moisture-resistant wrapping and packed on wooden pallets for export transportation.

Packaging should protect slit edges and the decorative surface against abrasion, moisture and movement during transportation.

For coil supply, buyers can specify coil ID, outside diameter, maximum coil weight, winding direction and pallet configuration according to their material-handling equipment.
