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

Our Production Strength

Automated continuous production lines for metal sandwich panels and high-speed coil perforation

Annual output capacity of 1,000,000+ meters - large phased projects supplied on schedule

High-precision EPS, rock wool, and glass wool composite panel lines

On-site inventory of thousands of tons - short lead times for repeat orders

Strict production to international, national, and enterprise standards, with fire performance test reports supplied for export approvals

Magnesium Oxysulfide Sandwich Panel - Built for Fire and Moisture

Magnesium oxysulfide (MOS) is an upgraded magnesium-based core with enhanced water resistance compared with standard MgO products. It maintains A-grade fire performance while resisting humidity, condensation, and wet-process cleaning - the ideal core where moisture is the enemy.

Key Advantages

A-grade fire resistance with low smoke emission

Superior moisture and water resistance - no swelling or strength loss in humid conditions

Anti-mold and anti-bacterial

Resistant to chemical cleaning agents and disinfectants

High strength with moderate weight

Stable long-term performance in wet or washdown areas

Ideal Applications

Food processing and seafood plants

Wet-process workshops

Cold storage antechambers

Coastal or high-humidity facilities

Pharmaceutical wash areas and sterilization rooms

Any environment with steam or frequent washdowns

MOS vs. Standard MgO Cores

Both are magnesium-based with A-grade fire performance. MOS is the right choice when humidity, washdowns, or condensation are part of daily operations. For dry environments with heavy impact exposure, the MgO Rock Wool Sandwich Panel or MgO Grid Panel remain strong options.
