3003 H24 Prepainted Aluminum Coil for Wall Cladding
PPGI.LTD supplies 3003 H24 prepainted aluminum coil for cladding. H24 is the temper of the coil. It tells us how hard and formable the metal is. This alloy gives wall panels useful strength. We match the coil to your panel and production line.
Is 3003 H24 Right for Your Wall Panel?
3003 H24 is stronger than very soft 1000-series aluminum. It still forms well for many wall panels.
| Panel need | What 3003 H24 offers | Still check |
|---|---|---|
| Simple wall panel | Useful strength and formability | Thickness and support |
| Folded cassette | Can take common folds | Bend radius and corner detail |
| Deep or difficult shape | May need another temper | Tooling and forming trial |
Send us the panel drawing. We will check the folds and thickness. The Aluminum Association’s alloy guide describes 3003 as a workable, general-purpose alloy.
Will the Coil Fit Your Panel Line?
The finished panel width is not the coil width. Folds and edges use extra metal.
| You send | We check | Result |
|---|---|---|
| Panel drawing | Bends and finished size | Suitable feed width |
| Line limit | Maximum width and coil weight | Coil that fits the machine |
| Surface side | Visible face and back | Correct coating orientation |
Send the panel drawing and line limits. We will confirm the feed width and coil weight. We can also mark the visible side for loading.
How Do We Check Flatness and Paint Adhesion?
A flat panel starts with clean metal. The paint must also handle the planned bends.
| Control point | Before production | After production |
|---|---|---|
| Surface | Clean substrate and pretreatment | Visual check |
| Paint | Agreed primer and topcoat | Coating and adhesion checks |
| Batch | Approved color and gloss | Keep visible panels together |
We confirm the surface treatment and paint system before production. We can also provide the agreed inspection records. PCI’s coil-coating overview explains why cleaning and surface treatment matter.
Buyer Concern & FAQ
Is 3003 H24 suitable for every facade panel?
No. Panel size, folds, supports, and design still matter. Send us the panel drawing before ordering.
Can you supply a custom feed width?
Yes. We will check the panel drawing and line limit first. Then we can confirm the slit width and tolerance.
How do you reduce color differences?
Use one approved sample. Tell us which panels will be installed together. We can plan the batches around that area.
Is 3003 H24 aluminum completely rustproof?
No material is free from corrosion risk. Aluminum does not form red rust like carbon steel. Good joints and drainage still matter.
