When buyers evaluate a sandwich panel supplier for an industrial, cold storage, or warehouse project, the factory behind the product often matters more than the brochure. LIAOHE has built its export business on a single, transparent premise: factory-direct supply from a specialized, high-volume manufacturing base.
Based in Shandong, China — the country’s most concentrated region for steel and insulated panel production — LIAOHE operates a 60,000 m² manufacturing facility with six continuous sandwich panel production lines and an annual output capacity exceeding 2,000,000 m². Since 2008, the company has supplied PU, PIR, EPS, and rock wool sandwich panels to more than 30 countries, with repeat shipments to Indonesia, Chile, Peru, Colombia, and other key markets.
What Factory-Direct Means for International Buyers
Factory-direct supply removes distributor margins and reduces the risk of specification drift between order and delivery. At LIAOHE, every order — from a single 40HQ container to a multi-container industrial project — is planned against the production schedule, steel-coil allocation, and quality-control checkpoints inside the same facility.
Key advantages for export buyers include:
- Consistent panel specification: Core density, steel thickness, coating type, and joint geometry are controlled line-by-line.
- Custom lengths and profiles: Continuous lines cut panels to project-specific lengths within container-loading limits.
- Traceable quality control: Incoming steel coils, core materials, and finished panels are checked before packing.
- Integrated export packing: Panel bundles, corner protection, and container bracing are planned in-house.
Production Equipment and Capacity
The LIAOHE plant is organized around six continuous production lines dedicated to different panel systems:
- PU and PIR insulated roof and wall panels
- Rock wool fire-rated roof and wall panels
- EPS economical wall and roof panels
- Cold-room and clean-room panel systems
- Specialty profiles and custom-width orders
This equipment mix allows LIAOHE to quote multiple core materials and thicknesses from the same factory, which simplifies procurement for contractors running mixed-envelope projects.
Quality Control Process
Quality at LIAOHE is structured around three checkpoints:
- Incoming material inspection: Steel coils are checked for thickness, coating weight, and color consistency. Core materials are verified for density and reaction parameters.
- In-process monitoring: Panel thickness, adhesion, and dimensional tolerance are checked during continuous production.
- Final inspection before packing: Finished bundles are inspected for surface finish, edge alignment, and label accuracy before moving to the packing area.
Test reports and certifications — including CE, ISO, and CPR documentation — are prepared according to destination-market requirements.
Export Packing and Container Loading
Panel damage during sea freight is one of the most common complaints in international sandwich panel supply. LIAOHE addresses this with a packing protocol developed across thousands of container shipments:
- Bundle wrapping: Panels are wrapped in protective film to prevent moisture and surface scratching.
- Wooden pallet bases: Bundles rest on wooden bases for forklift handling and load distribution.
- Corner protection: Edge protectors and separators prevent panel-to-panel contact.
- Container bracing: Wooden frames and tension straps lock bundles in place inside 40HQ containers.
Who LIAOHE Supplies
LIAOHE’s export shipments serve a range of project types and buyer profiles:
- Industrial factories and warehouses
- Cold storage and cold-chain logistics centers
- Food processing plants and clean rooms
- Poultry farms and agricultural buildings
- Mining and remote-site construction camps
- Commercial and logistics facilities
Project references include 13×40HQ rock wool roof panel deliveries to Indonesia, 9,500 m² rock wool wall panel systems for Guatemala, and PU roof panel projects across Central America and the Middle East.
Why Factory Scale Translates to Buyer Confidence
Large sandwich panel orders require production stability. A factory with multiple continuous lines can absorb schedule changes, run parallel material grades, and maintain delivery windows even when individual orders require custom lengths or coatings. For international buyers, that scale reduces the risk of partial shipments, quality variance, and missed deadlines.
LIAOHE’s facility is designed for exactly this kind of volume-export work: long production runs, integrated packing, and direct coordination with freight forwarders for FOB and CIF shipments.
