Marble Pattern Steel Sheet for Cleanroom Wall and Ceiling Panels
PPGI.LTD supplies marble pattern steel sheet for cleanroom wall and ceiling panels with custom finish, sheet sizes, and surface requirements. We match the face to the cleaning plan and the dimensions to the wall and ceiling modules.

Which Marble Finish Fits the Walls and Ceiling?
A smooth face is easier to inspect than a deep texture. Keep the vein pattern simple enough for the cleanroom design.

We can match the pattern and gloss to an approved sample. Any anti-static or special cleaning claim must be tied to the ordered coating and report.
Which Sheet Size Fits the Panel Layout?
Use the room module and panel line to choose width and cut size.
| Layout item | Typical direction | What to confirm |
|---|---|---|
| Sheet width | 1000 or 1200 mm direction | Panel and line width |
| Custom shearing | Cut blanks when ordered | Cut list |
| Thickness | Matched to panel build | Wall or ceiling design |
| Protective film | Matched to fabrication | Removal plan |
| Pattern direction | Matched to room layout | Wall and ceiling map |
PPGI.LTD can supply coils or confirmed cut sizes for the modular layout. Exact widths and tolerances follow the order and processing route.
How Do You Keep the Joints Clean and Sealed?
The surface cannot make a cleanroom wall complete on its own. Joints and trims must also stay smooth and cleanable.

ISO 14644-1 defines cleanroom air classification. We match the sheet size and finish, while the cleanroom designer controls joints, sealants, and room performance.
Buyer Concern & FAQ
Which disinfectants can be used on the surface?
It depends on the cleaner, concentration, contact time, coating, and wiping tool. Test the specified cleaning plan before approval.
Can the sheet be supplied in custom cut sizes?
Yes. Send the cut list, tolerances, pattern direction, and edge requirement. We will confirm the practical production plan.
How should cleanroom panel joints be sealed?
Use the sealant, trim, and joint detail approved for the complete cleanroom system. Keep seams smooth and accessible for cleaning.
Is an anti-static option available when specified?
Yes, when the required property, test method, and acceptance value are written into the order. It is not an automatic feature of every marble sheet.
