Engineered to satisfy strict Fire Safety Building Codes and energy conservation standards in South Korea.
Over the last decade, South Korea has drastically reinforced its Building Act regulations regarding industrial building envelopes. In response to complex fires in commercial warehouses and logistics facilities within Gyeonggi-do and Incheon, structural design requirements now mandate rigorous performance metrics. Standard EPS (Expanded Polystyrene) and low-grade PU (Polyurethane) panels are rapidly being phased out in favor of structural materials that deliver verified non-combustibility.
As a leading exporter to the Korean Peninsula, we supply Rock Wool Sandwich Panels designed to meet local thermal regulations and fire resistance criteria. Our systems offer structural architects and engineering firms in Pyeongtaek, Cheongju, and Busan the safety levels required for high-occupancy structures, battery gigafactories, and multi-tier logistics centers.
Industrial developers worldwide are transitioning towards high-R-value, sustainable building solutions.
Globally, industrial construction projects face strict criteria under LEED, BREEAM, and regional green building certifications. Modern infrastructure requires energy-saving envelopes that lower operational heating and cooling demands. High-density Rock Wool Sandwich Panels address these challenges by providing both effective thermal barriers and high-level fire resistance.
Additionally, global logistics operators (such as Amazon, Coupang, and DHL) require building materials with verified safety profiles to secure favorable property insurance terms. By using mineral wool core panels, facility owners can lower their insurance premiums and protect their long-term capital investments.
Operating out of Ningbo, China, we utilize automated continuous sandwich panel production lines that enable consistent panel flatness, density distribution, and strong adhesive bonding. By sourcing our structural steel coils and high-purity basalt mineral wool directly from bulk suppliers, we maintain stable production output and competitive pricing.
We customize outer sheet profiles, steel gauges (0.4mm - 0.8mm), and core thicknesses to match local drawings. We supply complete shop drawings, connection detail schematics, and container loading maps to facilitate on-site assembly.

Technological trends shaping modern building designs.
To combine the thermal properties of Polyurethane (PU) with the fire safety of Mineral Wool, we offer panels with polyurethane-sealed edges. This composite design improves airtightness, prevents moisture intrusion, and enhances the overall strength of the structural joints.
In line with the global focus on reducing embodied carbon, our basalt fibers are sourced from energy-efficient electric furnace operations. Additionally, we provide high-durability steel options with zinc-aluminum-magnesium coatings that offer long-term protection against corrosion.
Modern developers prioritize fast, cost-effective assembly. Our panels are manufactured to close dimensional tolerances, featuring pre-punched utility routes and custom tongue-and-groove joint systems that simplify onsite installation.
Our panels are engineered to perform under high structural stress, with high shear strength and pull-out resistance to withstand typhoons and high wind loads typical of coastal regions in the Far East.
Key information regarding logistics, compliance, and custom engineering options.
Yes. Our mineral wool core panels are designed to meet Class A1/Grade 1 non-combustible material requirements, equivalent to KS F ISO 1182 and KS F 2271 standards commonly referenced by South Korean building authorities.
Production cycles generally require 10 to 15 days depending on the volume and customization needs. Ocean transit from Ningbo Port to major South Korean ports (Incheon, Busan, Gwangyang) typically takes 3 to 5 days.
Yes. We offer standard RAL color options and specialized finishes like PVDF, SMP (Silicon Modified Polyester), and PE coatings, with steel coil thicknesses ranging from 0.4mm to 0.8mm.
Polyurethane side-sealing protects the mineral wool core from absorbing moisture, improves the structural strength of the joint connection, and reduces air leakage, resulting in more stable thermal insulation over time.
For partition walls and lightweight roof structures, we supply a core density of 100-110 kg/m³. For heavy-duty external walls, roofs, or cleanrooms requiring high fire ratings, we offer high-density mineral wool of 120-150 kg/m³.
Yes. We provide matching flashing systems, ridge caps, structural screws, sealant, EPDM gaskets, and custom-formed steel profiles to ensure consistent thermal performance across all wall joints.
All finished panels are wrapped in protective PE film, packed in bundles, and loaded on EPS protective blocks. The bundles are secured inside shipping containers using heavy-duty straps to prevent shifting during transit.
Yes. Our mineral wool cores provide sound attenuation. For high-noise environments, we offer perforated inner steel sheets that act as sound-absorbing panels for industrial facilities.
Our typical minimum order quantity is 500 square meters. This allows us to run continuous production lines efficiently, helping to minimize material waste and maintain cost-effective pricing.
