About Kexinda - Engineering Clean Environments Since 2009

Kexinda (Tianjin) Industrial Co., Ltd. is a professional manufacturer of new-generation building panels and integrated cleanroom enclosure systems. Headquartered in Tianjin, China - one of northern China's largest steel and color-coated sheet distribution hubs - we combine the raw-material location advantage with in-house production to deliver certified quality at genuinely competitive prices.

Founded in 2009, Kexinda integrates research, design, manufacturing, and installation under one roof. This full-chain capability means our engineers control every variable that matters to your project: core density, facing thickness, joint precision, fire performance, and packing for ocean freight.

What We Manufacture

Cleanroom sandwich panels - 9 core options including rock wool, MgO rock wool, gypsum rock wool, aluminum honeycomb, gypsum aluminum honeycomb, MgO grid, fire-retardant paper honeycomb, silicon-rock, and magnesium oxysulfide (MOS)

Purification enclosure systems - walls, ceilings, doors, and view windows for GMP, food, electronics, and healthcare cleanrooms

Composite panels - MgO rock wool composite boards, paper honeycomb composite boards for labs and dust-free workshops

Structural products - floor decking (steel truss deck), CZ purlins, corrugated and perforated profiled sheets, aluminum-magnesium-manganese panels

Silicon-Rock Sandwich Panel - The Balanced Performer

The silicon-rock core is a lightweight inorganic composite engineered to combine near-A-grade fire performance with low density. It fills the gap between paper honeycomb economy and rock wool performance, making it one of the most versatile cores for modern cleanroom and controlled-environment projects.

Key Advantages

Lightweight with high fire rating (A2–B1) - safety without heavy supporting steel structure

Very good thermal insulation - energy-efficient enclosures

Fine closed-cell structure with low water absorption

Smooth, flat panel surface for cleanroom-grade finishing

Strong cost-to-performance ratio

Reduced freight cost per square meter for export projects

Ideal Applications

Electronics and precision manufacturing cleanrooms

Food and beverage processing rooms

Cold-chain support areas

General clean partitions

Projects balancing fire code, weight, and budget

Silicon-Rock vs. Neighboring Cores

vs. Fire-Retardant Paper Honeycomb: silicon-rock upgrades fire class and insulation at moderate added cost

vs. Rock Wool: rock wool wins on acoustic absorption and A1 rating; silicon-rock wins on weight and handling speed
