Magnesium Sandwich Panel

Magnesium Oxide Panel (short for MGO / Glass Magnesium Purification Panel) is a high-performance inorganic cleanroom enclosure panel with hollow grid magnesium oxide core, widely recognized as the optimal solution for high-humidity, high-fire-risk sterile environments.

It adopts double-sided hygienic metal skins, surrounded by galvanized steel reinforcing frames, filled with hollow grid magnesium oxide inorganic core via hot pressing curing craft. Exclusive hidden tongue-and-groove interlock with EPDM sealing strips eliminates sanitary dead corners and air leakage gaps.

Different from rockwool, EPS and PU panels, the fully inorganic MGO core combines A1 non-combustible fire safety and excellent moisture/mold resistance, solving deformation and mildew issues of organic foam cores in damp clean zones. Two mainstream versions: hollow pure MGO grid panel, handmade MGO-rockwool composite panel.

Main Structure & Material Breakdown

1. Outer Metal Facer Sheets

3 customizable surface options matching different cleanroom grades:

1. Standard Antibacterial PPGI Pre-painted Galvanized Steel

   0.4–0.6mm thickness, matte white RAL9003 silver-ion antibacterial coating (≥99.9% bacteria inhibition rate ISO22196), anti-fingerprint non-porous surface, resistant to alcohol, hydrogen peroxide and chlorine disinfectant wiping. Cost-effective for electronics, cosmetic and medium-standard food cleanrooms.

2. SUS304 / SUS316L Stainless Steel Facer (Medical Premium)

   Wire-drawing anti-corrosion surface, withstands long-term repeated heavy disinfection mist, mandatory for hospital operating rooms, vaccine production lines and high-humidity food aseptic filling workshops.

3. ESD Anti-static Coated Steel (Electronics Special)

   Surface resistance 10⁶~10⁹Ω, eliminates static discharge damage to semiconductors, chips and optical components.

2. MGO Core (Core Differentiator vs Rockwool / PU Panels)

• Raw material: Inorganic magnesium oxide + magnesium chloride reinforced glass fiber grid, hollow lattice hollow structure

• Fire rating: EN13501 Class A1 fully non-combustible, melting point >1000℃, no molten dripping, no toxic smoke release during fire, 60–180min fire resistance limit by panel thickness

• Moisture & mold performance: Zero water absorption, dimensional expansion rate <0.3% under 95% RH high humidity, completely anti-mold, no deformation or bubbling in long-term humid environment (core advantage over rockwool and PU)

• Structural rigidity: Hollow grid interlocking structure provides ultra-high compressive & impact resistance, anti-dent under collision of medical trolleys and production equipment, stable for long-span ceiling installation

• Environmental property: Asbestos-free, formaldehyde-free, non-toxic inorganic material, no volatile organics released into clean air

3. Two Main Production Craft Versions

Version 1: Hollow Pure Glass Magnesium Panel (Most Popular)

Full hollow MGO grid core, all inorganic structure, light weight, ultra moisture-proof, perfect for food, dairy, seafood processing high-humidity clean workshops. Hidden tongue-and-groove lock with built-in EPDM foam gasket for airtight splicing. All internal edges chamfered to rounded arcs to eliminate dust hiding gaps, fully compliant with GMP sanitary requirements.

Version 2: Handmade MGO + Rockwool Composite Panel (Dual Premium Performance)

Surrounding MGO reinforced frame + internal rockwool filling, combines MGO’s high rigidity/moisture resistance and rockwool’s superior sound insulation. Four-side galvanized steel reinforced frame, better flatness and load-bearing capacity, recommended for hospital OR, pharmaceutical Grade A/B aseptic workshops requiring both fire safety and noise reduction.

4. Matching Aluminum Purification Profile System (Compatible with your technical drawing)

Full supporting aluminum extrusion accessories for seamless installation without sanitary dead corners:

JH001A vertical keel, JH213/JH214 panel locking strips, 230 integrated curved inner/outer corners, 236 T-shaped cross connectors, JH236 wall base skirting, air shower/pass box pre-cut openings reserved at factory to avoid dust-generating on-site cutting.

5. Standard Sizing Specifications
