Metallic Sandwich Panel

Surface Material

Easywall Co., Ltd. utilizes premium domestically-sourced color-coated steel panels. These panels employ cold-rolled steel sheets (electro-galvanized/hot-dip galvanized or aluminum-zinc alloy coated) as substrates, which undergo a rigorous production process including: Degreasing → Phosphating → Chromate treatment → Continuous roller coating of organic polymers → Baking and cooling.

Product Advantages: High structural strength / Superior corrosion resistance / Aesthetically refined appearance

Stainless Steel Sheet

Thickness: 0.5mm / 0.6mm, Width: 1000mm / 1200mm, Surface Material: 304/2B

Finish: Front side: Satin finish / Back side: Color-coated

Key Advantages: Enhanced chemical resistance / Reduced gloss for refined aesthetics / Superior design integration

Refill Material

Multiple core materials available for selection

Adhesive

2K PU Adhesive

Our selected adhesive is SGS-certified and complies with European Standard N71 Part 3 for environmental requirements. It demonstrates exceptional durability under extreme conditions: Temperature cycling tests: -20 °C to +60°C; Baking duration: 12 hours per cycle; 100 test cycles with no bond strength degradation

Easywall Co., Ltd. provides innovative cleanroom partition solutions for pharmaceutical, electronics, food processing, chemical, and cosmetics industries through dedicated R&D and manufacturing.

FAQ – Cleanroom Sandwich Panel

1. Which Cleanroom Panel is best for pharmaceutical cleanrooms?

For pharmaceutical environments, the most commonly used options are:

● Rock wool sandwich panel → best fire resistance (Class A)

● HPL surface panels → chemical resistance + easy cleaning

● Aluminum honeycomb panels → high flatness + durability

Selection depends on GMP requirements, fire rating, and cleaning chemical exposure.

2. What thickness is standard for Cleanroom Wall Panels?

Typical thickness ranges:

● 50mm → standard cleanroom partition wall

● 75mm → higher insulation requirement

● 100mm → cold room or strict temperature control areas

● 150mm+ → special industrial applications

3. Are Cleanroom Sandwich Panels fire resistant?

Yes. Fire resistance depends on the core material:

● Rock wool → Class A1 non-combustible

● MGO board → high fire resistance

● PU/PIR → self-extinguishing (B1 level)

Fire-rated panels are required in pharmaceutical and electronic cleanrooms.

4. What is the lifespan of Cleanroom Sandwich Panels?

High-quality metal cleanroom wall panels typically last:

● 15–25 years depending on environment

● Longer in controlled humidity and non-corrosive environments

Stainless steel and aluminum surface panels have longer durability.

5. What is the price of Cleanroom Sandwich Panels?

Price depends on:

● Core material (rock wool, PU, honeycomb)

● Surface material (steel or stainless steel)

● Thickness

● Fire rating requirements

● Project scale

Most suppliers provide custom quotation based on project design.
