The main structure of the clean room consists of three main materials. The most commonly used and stable ones in the industry are as follows. I will explain clearly without any circumvention:
1. Frame material (load-bearing skeleton)
Aluminum alloy profiles (most commonly used, highest cost-effectiveness)
Lightweight, non-corrosive, quick to install
Preferred for electronics factories, clean rooms, and general dust-free workshops
Life expectancy: 8 to 12 years
304 stainless steel frame (for medicine, food, and high-humidity environments)
Corrosion-resistant, easy to clean, high strength
Used in pharmaceuticals, medical devices, and food factories
Life expectancy: 10 to 15 years
Square steel with powder coating / galvanized iron (cheap, temporary, low requirements)
Low cost, but prone to moisture, easy to rust
The lifespan in humid environments will be significantly shortened
Life expectancy: 5 to 8 years
2. Enclosure panels / partitions (the enclosed part)
Clean color steel plates (EPS / rock wool / magnesium)
Most standard and universal
Sound insulation, heat insulation, flat and easy to clean
Tempered glass / acrylic plates
Transparent, beautiful, easy to observe
Suitable for display areas, laboratory clean rooms
PVC soft curtains (simple, low cost)
Quick to dismantle and install, cheap
But prone to aging, poor sealing
Industry’s simplest conclusion
For ordinary electronics / dust-free workshops: Aluminum alloy frame + clean color steel plates
For medicine / food / high-humidity environments: 304 stainless steel frame + clean plates / glass
For temporary / low-cost: Iron square tubes + PVC soft curtains
