3003 5005 5052 H24 Orange Peel Pattern Stucco Embossed Aluminum Roofing Coil
“3003 5005 5052 H24 Orange Peel Pattern Stucco Embossed Aluminum Roofing Coil” sounds long and technical, but for roofing buyers it really boils down to one idea: a lightweight, corrosion‑resistant aluminum coil with a decorative, functional texture that performs reliably on roofs in demanding environments.
Below is a clear, customer‑focused look at what this product actually is, why the orange peel / stucco embossing matters, and how the different alloys and tempers change performance in real applications.
What is orange peel / stucco embossed aluminum roofing coil?
Orange peel (also called stucco) embossed aluminum coil starts as a flat aluminum strip, then passes through a patterned roller that presses a shallow, irregular texture into the surface. The result looks like the skin of an orange or a rough plaster wall.
For roofing use, this texture is not just cosmetic:
- It hides minor dents, oil stains, and handling marks, keeping roofs visually consistent over time.
- It scatters light, reducing glare on bright sunny days.
- It can improve adhesion for coatings, paints, and bonding films.
- It adds slight stiffness compared with a completely smooth sheet of the same thickness.
When wound into coils, it’s easy to transport, uncoil, cut, and profile into roofing panels, flashings, or cover strips on site or in a fabrication shop.
Why 3003, 5005, and 5052 alloys?
All three alloys are non‑heat‑treatable, corrosion‑resistant aluminum grades commonly used outdoors. They differ mainly in strength, corrosion resistance, and formability.
3003 aluminum
- Aluminum–manganese alloy
- Good general corrosion resistance
- Very good workability and formability
- Moderate strength, suitable for standard roofing sheets, soffit panels, and decorative cladding
5005 aluminum
- Aluminum–magnesium alloy (low magnesium content)
- Better corrosion resistance than 3003 in many outdoor environments
- Matches the color/appearance of 6060/6063 extrusions after anodizing, useful if you need consistent aesthetics between sheets and profiles
- Slightly higher strength than 3003 while remaining easy to bend and form
5052 aluminum
- Aluminum–magnesium alloy with higher magnesium
- High corrosion resistance, especially in marine, coastal, and industrial atmospheres
- Higher strength than both 3003 and 5005
- Excellent for roofing and cladding exposed to salt spray, acid rain, or heavy mechanical stresses
In simple terms:
Use 3003 where cost and formability matter most, 5005 where appearance and anodizing compatibility are important, and 5052 where durability and corrosion resistance are critical.
H24 temper for roofing coils
Temper describes how the metal has been processed to reach a balance of strength and formability.
“H24” is a common temper for roofing coils and means:
- The coil has been strain‑hardened (cold‑worked) to a half‑hard condition.
- It has then been partially annealed to relieve internal stresses and restore some ductility.
For roofing manufacturers, H24 gives:
- Enough strength for wind resistance, panel rigidity, and long spans (within reasonable limits).
- Enough ductility for roll forming, bending, seaming, and profiling without cracking.
- Better resistance to damage during handling compared with very soft tempers like O or H14.
In short, H24 is a good midpoint temper: strong enough to perform structurally on the roof, but still friendly to process in your equipment.
parameters for orange peel stucco embossed roofing coil
To select the right coil, roofing buyers usually pay attention to a few parameters:
Thickness range
Typical roofing coils in these alloys are supplied around 0.20–1.50 mm thickness.
Thinner gauges are used for interior ceiling panels or non‑structural cladding; thicker gauges are used for exterior roofing, wall systems, or areas with higher wind loads.
Width
Common widths range from about 600 mm up to 1600 mm, depending on your forming line and profile design. Wider coils allow wider panels and fewer joints; narrower coils can reduce waste for specific profiles.
Coil inner and outer diameter
Standard inner diameters are often 405 mm, 505 mm, or similar sizes to fit common decoilers. Outer diameter typically falls around 1200–1500 mm, tuned to your handling equipment and transport conditions.
Surface condition
- One side or both sides embossed with orange peel stucco pattern.
- Optional protective film to prevent scratching during forming and installation.
- Bare mill finish, anodized, or pre‑painted (PVDF, polyester, etc.) depending on project needs.
Mechanical properties (typical for H24, for reference only; exact values depend on specification):
3003 H24:
- Tensile strength: approx. 130–180 MPa
- Yield strength: approx. 60–135 MPa
- Elongation: typically 5–15%
5005 H24:
- Tensile strength: approx. 145–185 MPa
- Yield strength: approx. 65–160 MPa
- Elongation: typically 5–12%
5052 H24:
- Tensile strength: approx. 195–245 MPa
- Yield strength: approx. 120–195 MPa
- Elongation: typically 5–12%
These strength levels are well suited for roll‑forming into standing seam panels, corrugated sheets, tile profiles, and flashing systems.
Chemical composition comparison
Below is a typical chemical composition table for these alloys. Actual production ranges must comply with relevant standards (such as ASTM B209, EN 573, or equivalent):
| Alloy | Si (%) | Fe (%) | Cu (%) | Mn (%) | Mg (%) | Cr (%) | Zn (%) | Others (each) | Others (total) | Al (approx.) |
|---|---|---|---|---|---|---|---|---|---|---|
| 3003 | ≤ 0.60 | ≤ 0.70 | 0.05–0.20 | 1.0–1.5 | – | – | ≤ 0.10 | ≤ 0.05 | ≤ 0.15 | Balance |
| 5005 | ≤ 0.30 | ≤ 0.70 | ≤ 0.20 | ≤ 0.20 | 0.50–1.1 | – | ≤ 0.25 | ≤ 0.05 | ≤ 0.15 | Balance |
| 5052 | ≤ 0.25 | ≤ 0.40 | ≤ 0.10 | ≤ 0.10 | 2.2–2.8 | 0.15–0.35 | ≤ 0.10 | ≤ 0.05 | ≤ 0.15 | Balance |
Manganese in 3003 and magnesium (with chromium) in 5052 are the elements that improve strength and corrosion resistance compared with pure aluminum, without sacrificing workability.
Implementation standards and quality control
High‑quality orange peel stucco embossed aluminum roofing coils can be produced to meet international or regional standards such as:
- ASTM B209 for aluminum and aluminum‑alloy sheet and plate
- EN 485 / EN 573 for aluminum sheet mechanical properties and chemical composition
- ISO quality systems for process control
For buyers, this means:
- Coil thickness, width, and flatness are controlled within tight tolerances.
- Embossing depth and pattern are consistent from coil to coil, avoiding visual mismatch on large roofs.
- Mechanical properties meet specified yield and tensile strength, ensuring predictable performance in engineering calculations.
- Surface quality is inspected for defects such as stains, corrosion spots, large scratches, or pattern discontinuities.
When the coils are pre‑painted, additional coating standards (such as ASTM D2244, D523, or AAMA specifications for color retention, gloss, and durability) may also be applied.
Where this product really works best
The unique mix of embossing, alloy, and temper makes these coils suitable for:
- Residential and commercial roofing sheets and tiles
- Standing seam roofs where appearance and long life are
- Coastal and marine buildings, especially with 5052 H24
- Industrial plant roofing and cladding subject to corrosive atmospheres
- Insulation jacketing and protective coverings for rooftop HVAC and piping
- Interior ceiling panels and decorative fascias where the orange peel pattern is part of the design
The orange peel stucco surface turns a purely functional metal sheet into a more forgiving, visually stable skin for the building, while the choice between 3003, 5005, and 5052 allows you to tune the balance between cost, strength, formability, and corrosion performance.
Summing up
“3003 5005 5052 H24 Orange Peel Pattern Stucco Embossed Aluminum Roofing Coil” describes a family of roofing materials rather than a single product:
- The orange peel / stucco pattern improves appearance and hides minor flaws.
- The H24 temper balances strength and formability for roofing fabrication.
- 3003, 5005, and 5052 provide options from economical general‑purpose performance to high‑end corrosion resistance in harsh coastal or industrial environments.
- Alloys are produced to recognized standards, with controlled chemistry and mechanical properties, to ensure consistent behavior in forming and on the roof.
For project designers and roofing manufacturers, selecting the right alloy and thickness within this family can significantly extend roof life, improve aesthetics, and reduce maintenance over time.
