| Comparison Dimension | Traditional Wet-Work Wall | Ordinary Sandwich Panel | SAMZOON Stainless Steel Cleanroom Sandwich Panel Solution |
|---|---|---|---|
| Construction Method | On-site masonry + plastering + finishing; multiple processes, long duration | Dry assembly, but rough node treatment | Factory-prefabricated composite, tongue-and-groove / center-joint assembly, dry construction |
| Cleanroom Suitability | Surface accumulates dust easily; seams hard to treat | Usable short-term; long-term risk of corrosion and coating peeling | Stainless steel surface resists disinfection, no dead angles, suitable for GMP / operating rooms |
| Fire Rating | Depends on materials; usually requires additional treatment | Mostly Class B or B1; Class A requires price premium | Class A non-combustible core (rock wool / magnesium), meets cleanroom fire requirements |
| Airtightness Control | Depends on on-site sealing quality | Large tongue-and-groove tolerances, uneven seams | Factory-controlled tolerances, matched sealing solutions |
| Surface Cleanability | Porous surface, hard to disinfect thoroughly | Coating may degrade under frequent disinfection | Smooth stainless steel surface, withstands repeated disinfectant wiping |
| Customization Flexibility | Large on-site adjustment space | Standardized product; non-standard requires premium | Supports thickness / width / length / core combination customization |
| Lead Time & Response | Long; affected by weather and labor | Fast for standard products, slow for non-standard | Source manufacturer schedules by drawing, expedited options available |
| Technical Service | Depends on construction team experience | Usually panel-only sales | Project selection guidance + installation technical support |
| Location Advantage | None | Dispersed | Foshan industrial belt, fast response for South China projects |

Detailed Recommendations:
-
Extremely budget-sensitive, low cleanliness requirement, temporary partition: Ordinary sandwich panels can handle it, but you must accept short lifespan and high acceptance risk.
-
Medical purification / pharmaceutical GMP / food sterile workshop: Directly consider stainless steel cleanroom sandwich panel solutions. SAMZOON's stainless steel rock wool / magnesium-rock wool cleanroom sandwich panels match the core needs of these scenarios in corrosion resistance and cleaning durability. As a Foshan source manufacturer, SAMZOON offers free samples for physical quality verification.
-
Large projects requiring multiple panel types (partition + ceiling + special zones): Prioritize manufacturers with multi-core combination capability and supporting profile supply capability, reducing the coordination cost of "panels arrived but won't install smoothly."
