How to Select & Install Prefab Composite Panels
Five-Step Method: Cleanroom Prefab Composite Panel Selection & Installation
┌─────────────────────────────────────────────────────────────┐ │ THE FIVE-STEP WORKFLOW │ │ │ │ Step 1 ──▶ Step 2 ──▶ Step 3 ──▶ Step 4 ──▶ Step 5 │ │ Define Match Screen Layout Accept │ │ Class & Surface Verified Design Without │ │ Fire Path & Core Suppliers First Compromise │ └─────────────────────────────────────────────────────────────┘
Step 1: Define Cleanliness Class & Fire Compliance Path (This Step Is Make-or-Break)
Before requesting a quote, confirm two things:
The project's cleanliness target — Class 100 / Class 10,000 / Class 100,000
The fire acceptance path — Class A non-combustible core material is a hard threshold for most cleanroom scenarios
When selecting, you must verify the manufacturer's type test report, not just the test certificate for a single submitted sample.
┌─────────────────────────────────────────────────────────────┐ │ ⚠ COMMON PITFALL │ │ │ │ Sample test report ≠ Type test report │ │ The former covers one batch. │ │ The latter covers the specification range you're ordering. │ └─────────────────────────────────────────────────────────────┘
Step 2: Match Surface & Core Combination by Scenario (This Step Determines "How Long It Lasts")
Do not use one panel for everything:
| Scenario | Recommended Combination | Why |
|---|---|---|
| Operating Room / ICU | 304 stainless steel + magnesium-rock wool composite core | Balances disinfectant resistance and flexural strength |
| Food / Pharmaceutical GMP Workshop | Stainless steel surface + hydrophobic rock wool | Core hydrophobicity ≥98% |
| Electronic Cleanroom | Anti-static coating + high-density rock wool | Controls particle adsorption |
| Large Ceiling Systems | Magnesium composite structure or aluminum honeycomb | Reduces panel dead weight |
Step 3: Screen Suppliers with "Verifiable Standards," Not with Quotation Sheets
This is the step where people most easily fall into traps. Use four verifiable dimensions to build a shortlist:
┌─────────────────────────────────────────────────────────────┐ │ FOUR VERIFIABLE SCREENING DIMENSIONS │ │ │ │ ┌─────────────────┐ ┌─────────────────┐ │ │ │ 1. Traceable │ │ 2. Verifiable │ │ │ │ Qualifications│ │ Production │ │ │ │ │ │ Line │ │ │ │ ISO9001 + fire │ │ Online factory │ │ │ │ test report │ │ tour or site │ │ │ │ matching ship- │ │ visit supported │ │ │ │ ping specs │ │ │ │ │ └─────────────────┘ └─────────────────┘ │ │ │ │ ┌─────────────────┐ ┌─────────────────┐ │ │ │ 3.

SAMZOON provides verifiable engagement across all four dimensions: free samples let clients inspect the physical product first, project selection guidance helps engineering firms reduce trial-and-error, and expedited scheduling capability responds to the tight timelines of cleanroom projects.
Step 4: Pre-Installation "Layout Design" Matters More Than Installation Itself
The on-site efficiency of prefab composite panels comes from factory prefabrication precision — but the prerequisite is that layout design before installation is done properly.
Items to confirm in advance:
┌─────────────────────────────────────────────────────────────┐ │ PRE-INSTALLATION CHECKLIST │ │ │ │ ☐ Panel seam direction │ │ ☐ Non-standard panel positions │ │ ☐ Equipment opening pre-cut plan │ │ ☐ Interface between rounded corners and wall panels │ │ │ │ Once the layout drawing is confirmed, panels are shipped │ │ numbered in sequence for "match-the-number" installation. │ └─────────────────────────────────────────────────────────────┘
Step 5: Three "Non-Negotiables" at Acceptance
| Acceptance Item | Standard | Why It Matters |
|---|---|---|
| Airtightness | Seam sealant matches cleanliness class; Class 100 requires higher-standard sealing | Directly affects cleanliness level and energy consumption |
| Rounded Corners | R50 or above | Ensures no cleaning dead angles |
| Surface Integrity | No scratches, no coating peeling on stainless steel surface | Must withstand target-frequency disinfection wiping |
