High-quality 3003 polyester coated aluminum coil offers excellent corrosion resistance, color retention, and long-lasting performance for architectural and industrial applications.
3003 polyester coated aluminum coil is one of the most widely used pre-painted aluminum materials in the construction, transportation, appliance, and advertising industries.
By combining the excellent corrosion resistance and formability of 3003 aluminum alloy with the decorative and protective properties of polyester (PE) belegg, manufacturers obtain a lightweight, durable, and cost-effective material suitable for both indoor and outdoor applications.
Compared with traditional galvanized steel, polyester-coated aluminum offers significant advantages in weight reduction, korrosjonsbestandighet, color stability, and recyclability.
The density of aluminum is only approximately 2.73 g/cm³, nearly one-third that of steel (7.85 g/cm³), enabling substantial savings in transportation and installation costs.
Modern coil-coating technology allows polyester coatings to achieve excellent adhesion, flexibility, impact resistance, and weather durability.
Depending on environmental conditions, properly manufactured PE-coated aluminum coils can provide a service life of 10–20 years or more, making them a preferred solution for roofing systems, wall cladding, ceiling panels, appliance casings, and decorative architectural applications.
3003 Polyester Coated Aluminum Coil
3003 polyester coated aluminum coil is aluminum coil coated through a continuous coil-coating process.
The aluminum substrate provides mechanical support, while the polyester coating provides decorative color and surface protection.
3003 aluminium is a 3xxx series aluminum-manganese alloy. It is not heat-treatable, but it can be strengthened through cold working.
Public alloy references describe 3003 as a general-purpose alloy with moderate strength, good workability, and good corrosion resistance.
It is commonly used in sheet metal products such as roofing, siding, gutters, downspouts, containers, signs, and decorative panels.
Compared with 1050 or 1100 pure aluminum, 3003 has better strength because manganese acts as the main alloying element.
This makes it more suitable for formed panels, cladding sheets, and products that need better dent resistance.
| Element | Typical Content | Function |
| Aluminium | Balansere, generally about 96.8-99% | Lightweight base metal |
| Manganese | 1.0-1.5% | Improves strength and structural stability |
| Copper | 0.05-0.20% | Slightly improves strength |
| Iron | ≤0.70% | Controlled impurity affecting surface and properties |
| Silicon | ≤0.60% | Controlled impurity affecting formability and appearance |
| Zinc | ≤0.10% | Controlled for corrosion stability |
| Others | ≤0.15% total | Controlled for consistency |
The manganese content is the key reason 3003 performs better than commercially pure aluminum in many coated coil applications.

Polyester coating (PE coating) is an organic coating system based on polyester resin technology.
It is one of the most widely used coil coating materials because it offers an excellent balance between performance and cost.
Key Characteristics of Polyester Coatings
Typical Coating Thickness
| Layer | Tykkelse |
| Primer | 5–7 μm |
| Top Coat | 15–25 μm |
| Back Coat | 5–10 μm |
The total coating system thickness generally ranges from: 20–35 μm depending on project requirements.
Kombinasjonen av 3003 aluminum alloy and polyester coating creates a synergistic performance advantage.

Typical polyester coating systems often use:
| Coating Position | Common Thickness Range |
| Front coating | 15-25 μm |
| Back coating | 5-10 μm |
| Primer | Usually included within the total system or specified separately |
For indoor panels, a thinner coating may be enough. For outdoor cladding, roofing, or gutters, buyers usually specify higher coating thickness and stronger weathering requirements.
| Coating Type | Main Advantages | Limitations | Best-fit Use |
| Polyester / PE | Economical, colorful, good formability, easy processing | Moderate UV and weather resistance | Interior panels, signage, ceilings, moderate outdoor use |
| PVDF | Excellent UV resistance and long-term weatherability | Higher cost | Premium exterior architecture |
| HDP | Better weather resistance than standard PE | Higher cost than PE | Outdoor building panels |
| SMP | Good hardness and weathering | Less flexible than standard PE in some systems | Roofing and wall panels |
| Epoxy | Strong adhesion and corrosion protection | Poor UV resistance | Back coat, primer, indoor protection |
Polyester is not always the longest-lasting coating, but it often offers the best balance of appearance, behandling, and cost for general applications.
