When Wansui Pharmaceutical needed a cleanroom enclosure system that could meet China's GMP standards and sustain ISO-class cleanliness over a large production floor, they selected Glostar's handmade cleanroom panels. This case study documents the project scope, product selection rationale, key performance parameters, and outcomes for a 17,000 m² pharmaceutical facility in Hebei Province.

Wansui Pharmaceutical is a licensed pharmaceutical manufacturer in Hebei Province producing solid-dose and liquid formulations for the domestic Chinese market. Their new production facility expansion required a cleanroom enclosure system covering 17,000 m² of wall and ceiling area across multiple production grades — including Class D (ISO 8), Class C (ISO 7), and Class B (ISO 5) zones.
The engineering team's selection criteria centred on four requirements:
Why Handmade Panels for a Pharmaceutical Project?
Unlike machine-continuous panels cut from coil stock, handcrafted cleanroom panels are fabricated as individual units with precision-folded steel edge returns and manually injected or laminated core. This process gives tighter dimensional control, better edge sealing, and reduced risk of delamination — making handcrafted panels the preferred choice for GMP pharmaceutical environments where panel integrity directly affects cleanliness classification.
The panels supplied to Wansui Pharmaceutical are produced at Glostar's Shandong manufacturing base under controlled conditions with automated surface coating lines and manual assembly stations for edge treatment and core insertion.
| Parameter | Specification |
|---|---|
| Panel Type | Handmade Cleanroom Sandwich Panel |
| Steel Skin Thickness | 0.426 mm – 0.5 mm colour-coated galvanised steel (PPGI) |
| Core Material Options | Rock wool (50 / 75 / 100 mm) |
| Standard Panel Width | 950 mm (effective); custom widths available |
| Standard Panel Length | Up to 12,000 mm (project-specific) |
| Surface Finish | Polyester or PVDF coating; RAL white standard (RAL 9016 / 9003) |
| Joint System | Tongue-and-groove concealed joint; anti-bacterial sealant applied at installation |
| Fire Rating | Class A non-combustible |
| Thermal Conductivity (λ) | Rock wool core: ≤ 0.040 W/(m·K) |
| Particle Generation | Low-particle-shedding surface; suitable for ISO Class 5–8 environments |

Delivering 17,000 m² of cleanroom panels for a pharmaceutical project demands more than manufacturing capacity — it requires coordinated scheduling, consistent batch quality, and on-site technical support. Key execution milestones for the Wansui project included:
17,000
m² of panels delivered — walls, ceilings, and partition systems across multiple cleanroom grades
Multi-Grade
Panels specified and supplied across ISO Class 5 through ISO Class 8 zones within the same facility
Shandong
Manufactured at Glostar's Shandong production base with batch traceability and QC inspection records
All panels were fabricated to project-specific cut lengths, minimising on-site waste and reducing installation time. Batch inspection reports — including dimensional checks, coating adhesion tests, and fire core certifications — were provided to the Wansui project team prior to shipment.
Given Hebei's climate — with cold winters (down to −15 °C) and hot humid summers — the core material selection prioritised thermal stability and moisture resistance. Rock wool core panels were selected for fire-rated partitions, while PIR core panels were used in temperature-controlled zones requiring enhanced thermal insulation (λ ≤ 0.022 W/(m·K)).
Following installation and commissioning, the Wansui Pharmaceutical cleanroom enclosure passed regulatory validation as part of the facility's GMP certification inspection. Key outcomes reported:
Project Team Feedback
"The panel flatness and joint consistency across 17,000 m² was notably high. We encountered no rework on joint gaps during the GMP inspection walkthrough — a result that reflected the quality control at the factory level."
