SS 5-Tier Perforated Cleanroom Storage Rack
Engineered for pharmaceutical sterile drying rooms, autoclave unloading bays, and cleanroom material storage. Features laser-perforated shelves with 20 mm pitch perforations that allow vertical laminar airflow to pass without obstruction.
Engineering Overview & Fluid Dynamics
Active contamination barrier and laminar downflow principles
The Himalayan Steel 5-Tier Perforated Cleanroom Storage Rack is designed to maximize vertical cleanroom storage density without compromising laminar airflow patterns. When solid shelves are used in laminar flow rooms, air stalls and creates dead zones where microbial spores can settle. Our perforated shelf tiers feature CNC laser-cut 15 mm round perforations with 20 mm pitch, allowing downward cleanroom airflow to pass freely around stored sterile trays, autoclaved tool kits, and component bins.

Cleanroom Construction & Architectural Design
cGMP sanitary fabrication details from our Baddi engineering works
Shelves are laser-cut with precision 15 mm holes, machine-deburred on both sides, and formed with double-return channel hemmed borders for structural rigidity.
Each shelf features an inverted welded stainless hat-section stiffener running beneath the centerline to prevent sagging under 150 kg loads.
Tapered split-sleeve split-collar locking system allows shelves to be repositioned in 50 mm increments without disassembling the entire rack.
38 mm diameter round or square stainless tubular pillars with welded top sanitary caps to prevent dust accumulation inside tubes.
Entire rack assembly is fully electropolished, creating a passive chrome-rich oxide layer that resists aggressive sporicides and autoclaving.
Optionally fitted with 100 mm heavy-duty polyurethane wheels with stainless steel housing and foot brake locks for effortless mobile transfer.
Standard Operating Protocol (cGMP SOP)
Standard operating guidelines and contamination control sequence
Step-by-Step Material Transfer Sequence
Sanitization & Wipe-Down Protocol
- Wipe down shelves and upright posts weekly using 70% IPA cleanroom wipes.
- Ensure wipe reaches both top and underside edges of perforated holes.
- Clean castor wheels and brake pedals weekly.
Fail-Safe Interlock Protection
- Dual-locking castor brakes secure both wheel rotation and swivel axis simultaneously.
Optional Engineering Customizations
Site-specific hardware adaptations
- Perforated 3-sided perimeter ledge wire guards to prevent items from sliding off shelves
- Solid stainless steel drip tray fitted under the bottom tier
- Document holder / clipboard bracket welded to upright post
- Autoclave-compatible high-temperature silicone castor wheels (rated to 140°C)
- Modular shelf partition dividers for organizing small vials and spares
Quality Validation Package (DQ/IQ/OQ)
Audit-ready documentation for US FDA and EU-GMP inspections
- Design Qualification (DQ) Documentation & CAD Drawings
- Installation Qualification (IQ) Assembly & Leveling Protocols
- Shelf Load Deflection Test Certificate (150 kg per tier verified)
- Material Test Certificate (EN 10204 Type 3.1) for Stainless Steel
Cleanroom Design Highlights
- 40% open perforated surface allows vertical laminar airflow to circulate freely around items
- CNC deburred hole edges guarantee zero sharp burrs that could tear cleanroom gloves or bags
- High 150 kg load capacity per tier supports heavy stainless autoclave trays and machine dies
- Adjustable shelf tiers allow customized spacing for tall containers or short petri dish racks
