1070 PVDF colour coated coating brick aluminum coil
1070 PVDF colour coated "brick" aluminum coil is a high-purity aluminum (AA 1070) substrate coil finished with a PVDF (polyvinylidene fluoride) paint system and patterned to deliver a brick/terracotta visual effect. It is designed for projects that need the warm texture of masonry while keeping the advantages of aluminum: low weight, corrosion resistance, fast fabrication, and consistent appearance across large areas.
This product is widely selected for architectural cladding, façade panels, soffits, ceilings, roof edging, and decorative envelopes, especially where long-term color stability and weather resistance are critical.
What makes this coil different
The value of 1070 PVDF brick-pattern coil comes from combining a very clean aluminum base with a high-performance fluorocarbon coating:
- AA 1070 substrate purity supports excellent formability and stable surface quality, helping the coating lay down smoothly and evenly.
- PVDF topcoat system offers strong resistance to UV fading, chalking, humidity, and atmospheric pollutants, making it ideal for exterior exposure.
- Brick/stone-like aesthetics enable designers to replicate traditional building textures without the weight, thickness, and installation complexity of real masonry.
- Coil coating consistency ensures uniform gloss, color, and film thickness from batch to batch, suitable for large continuous façades.
Typical applications
PVDF brick-pattern aluminum coil is commonly processed into sheet, panel, cassette, and profiled components. Typical end uses include:
- Exterior wall cladding and façade systems for commercial buildings, transit facilities, schools, and public venues
- Aluminum composite panel (ACP/ACM) skins and decorative aluminum veneers
- Roofing trims, flashings, fascia, gutters, and architectural edge closures requiring long-life coating
- Ceilings, soffits, canopies, and column wraps where visual warmth and corrosion resistance are desired
- Renovation and re-skin projects where reduced dead load and faster installation are important
Brick-style patterns are especially popular in Mediterranean, industrial loft, and heritage-inspired design languages, providing a masonry feel with clean metal detailing.
Base metal: AA 1070 chemical composition
AA 1070 is a commercially pure aluminum alloy with very low impurity limits. Composition may vary slightly by standard and supplier; values below are typical limits for reference.
| Element | Si | Fe | Cu | Mn | Mg | Zn | Ti | Al |
|---|---|---|---|---|---|---|---|---|
| Typical max (%) | 0.20 | 0.25 | 0.04 | 0.03 | 0.03 | 0.04 | 0.03 | ≥ 99.70 |
Why it matters: high-purity aluminum provides excellent corrosion resistance, stable surface reflectance, and very good bendability, supporting profiling and panel forming without sacrificing coating integrity when correct bending radii are used.
Coating system: PVDF brick colour coating
PVDF coating is commonly supplied as a multi-layer system applied by continuous coil coating lines:
- Pre-treatment: conversion coating to improve adhesion and corrosion resistance
- Primer: enhances bonding and barrier performance
- PVDF topcoat: color, pattern, UV durability, stain resistance
- Optional back coat: service-side protection and handling resistance
Brick patterns are typically created by printed/roller patterning and controlled gloss to mimic ceramic or fired clay tones. Customers may choose variations such as red brick, brown brick, terracotta, antique brick, or mixed masonry shading.
Typical coating build (reference ranges)
| Item | Typical range |
|---|---|
| Topcoat (PVDF) dry film thickness | 20–25 μm |
| Primer dry film thickness | 5–7 μm |
| Total dry film thickness (front) | 25–32 μm |
| Back coat (service/back side) | 5–10 μm |
Coating thickness can be customized for aggressive environments (marine, industrial) or for specific forming requirements.
technical specifications (common supply range)
The table below reflects common market supply for architectural coil. Actual availability depends on mill capacity, coating line width, and customer requirements.
| Parameter | Typical options |
|---|---|
| Alloy | 1070 (AA 1070) |
| Temper | O (annealed), H14/H16/H18 (as agreed) |
| Thickness | 0.20–1.50 mm (common architectural range: 0.30–1.20 mm) |
| Width | 600–1600 mm |
| Coil ID | 405 mm / 505 mm (common) |
| Coil OD | up to ~1600 mm (line-dependent) |
| Surface finish | Brick pattern PVDF, single-side or double-side coated |
| Gloss | matte / satin / semi-gloss (pattern-dependent) |
| Protective film | optional PE film for fabrication and transport |
| Edge condition | mill edge or slit edge |
Selection tip: for deep profiling or tight bends, choose softer temper (O or H14) and confirm bending radius with your fabricator to reduce risk of micro-cracking at the fold.
Performance highlights customers care about
Color stability and weather resistance
PVDF is well known for excellent UV resistance. In outdoor façades, it maintains color and gloss far longer than general polyester systems, especially under strong sunlight and heat cycling. This is a advantage for brick tones where fading can quickly make the façade look uneven.
Corrosion protection for real-world atmospheres
With proper pre-treatment and primer, PVDF coil offers strong resistance to humidity, salt-laden air, and industrial pollutants. This makes it suitable for coastal cities, high-rise buildings, and transportation corridors.
Lightweight masonry effect
Compared with brick veneer, aluminum coil delivers a dramatic reduction in dead load, which can simplify substructure design and speed up installation. It also supports modern façade geometries, including curved or folded surfaces, that are difficult with rigid masonry.
Fabrication-friendly
1070 aluminum is easy to cut, roll-form, stamp, and bend. The coating is engineered for coil processing, helping panels maintain a uniform look with controlled gloss and pattern repeat.
Typical mechanical and physical data (reference)
Values depend on temper and thickness; table below is general reference for 1070 series.
| Property | Typical value / range |
|---|---|
| Density | ~2.71 g/cm³ |
| Thermal conductivity | high (typical for pure Al) |
| Electrical conductivity | high (typical for pure Al) |
| Tensile strength (O to H18, approximate) | ~60–140 MPa |
| Yield strength (O to H18, approximate) | ~20–120 MPa |
| Elongation (varies widely by temper) | typically higher in O temper |
For design-critical mechanical requirements, specify temper and request mill test certificates for the exact coil lot.
Recommended project scenarios
| Scenario | Why 1070 PVDF brick coil fits |
|---|---|
| High-sunlight façades | PVDF reduces fading and chalking, preserving brick tones |
| Coastal buildings | Strong coating barrier performance against salt mist |
| Renovation overlays | Low weight and coil-to-panel processing speeds installation |
| Large-area cladding | Consistent pattern and color across long coil lengths |
| Decorative architectural details | Brick look without masonry thickness; easier corner solutions |
