ISO 5-8 Cleanroom Wall Panel Requirements and Selection Guide

The requirements for cleanroom wall panels vary significantly depending on the ISO classification. Here is a breakdown of key criteria and selection guidance:

ISO 5-6 (Class 100-1,000) - High-Cleanliness Core Areas:

• Primary Requirement: Extremely low particle emission and exceptional airtightness. Panels must have absolutely non-porous, monolithic surfaces.

• Material Choice: Electro-galvanized steel or stainless steel sandwich panels are mandatory. Surface coatings should be high-performance, smooth paints (e.g., PVDF/HDP).

• Critical Details: All joints, corners, and penetrations require airtight seals (silicone, welded). Rounded covings (≥50mm radius) at wall-floor and wall-ceiling junctions are essential.

ISO 7 (Class 10,000) - Controlled Production Zones:

• Primary Requirement: High durability, easy cleaning, and good airtightness. Smooth, hard, non-shedding surfaces.

• Material Choice: High-quality electro-galvanized steel sandwich panels with robust coatings remain the standard. Fire-resistant cores (mineral wool, alumina silicate) are often required.

• Critical Details: Sealed seams and appropriate coving are necessary. Panel finish must withstand frequent disinfection.

ISO 8 (Class 100,000) - Support or Buffer Zones:

• Primary Requirement: Smooth, cleanable surfaces with basic durability. Airtightness is still important but slightly less critical than in higher classes.

• Material Choice: Cost-effective options become viable, including:

  • High-quality galvanized steel panels.

  • Solid laminate panels (HPL) with sealed edges.

  • Fiberglass Reinforced Plastic (FRP) panels.

• Critical Details: Seams should be tightly fitted. Proper installation is key to prevent particle traps.

HUAAO GMP Pharmaceutical Packaging Cleanroom ISO 8 Steel Sandwich Panel
Our ISO 8 steel sandwich panels are engineered to meet the specific demands of pharmaceutical packaging environments where GMP compliance is paramount. They feature:

• GMP-Compliant Surfaces: Smooth, non-porous, and easy-to-clean coated steel faces, resistant to cleaning chemicals.

• Airtight Construction: Engineered tongue-and-groove joints with integrated gaskets to minimize air leakage.

• Durable Core: Utilizes fire-resistant mineral wool or other approved insulating materials that provide stability and meet safety standards.

• Seamless Integration: Designed for modular assembly to create monolithic-looking walls without dust-collecting gaps.

Selection Summary:

• For ISO 5-6 (Core): Choose highest-grade stainless or coated steel panels with welded or meticulously sealed joints.

• For ISO 7 (Main Zone): Choose high-quality coated steel panels with fire-resistant cores and sealed joint systems.

• For ISO 8 (Support Zone): Choose cost-effective, durable panels (coated steel, HPL) that prioritize cleanability and meet project-specific fire/safety codes.
