Explore our precision-engineered structural support, exterior panels, and modular cladding components optimized for modern thermal envelopes.
Modern building envelopes are undergoing a profound paradigm shift. As structural standards evolve under the influence of climate change policies and green building directives, designers must reconcile high thermal efficiency with structural robustness. In the sphere of exterior construction, insulated sandwich panels have emerged as the standard configuration for achieving net-zero energy buildings (NZEB).
OEM sandwich panels exterior systems offer a pre-engineered composite cladding solution that handles structural load, water barrier performance, vapor regulation, and thermal insulation in a single prefabricated element. This multi-functionality directly translates to reduced onsite labor overhead, accelerated construction timelines, and long-term envelope reliability. Globally, rapid commercial and industrial expansion—such as hyper-scale data centers, automated cold-storage facilities, and high-tech cleanroom centers—is driving the demand for specialized, high-performance exterior sandwich panels.
The name "Haofa" signifies a wide world with great potential. Under the visionary leadership of our founder, Ms. Zhang Xuedong, Tangshan Haofa International Trade Co., Ltd. has established itself as an industry leader, integrating industrial and commercial building materials supply, home improvement customization, and robust international trade logistics.
Over the last 25 years, our services have expanded to cover three major application scenarios: wall systems, ceiling systems, and ground systems. Our core product portfolio features light steel keels, high-precision gypsum boards, sound-absorbing mineral wool boards, PVC/WPC wall boards, hardware accessories, and bespoke functional furniture. By establishing deep cooperative partnerships with hundreds of premium factories across more than 20 cities in China, we deliver custom, high-caliber building envelope components directly to our customers.
Modern building construction calls for tailored exterior cladding that addresses project-specific environmental, architectural, and safety demands. Tangshan Haofa offers comprehensive solutions for commercial, industrial, and public developments:
We supply high-efficiency foam sandwich panels with specialized tongue-and-groove joints that minimize thermal bridging. These panels are essential for maintaining stable temperatures in modern cold storage facilities and agricultural hubs.
For data centers demanding strict climate control and high fire resistance, our rockwool and PIR cores provide robust structural stability, Class A fire protection, and thermal insulation to keep critical hardware safe.
Our systems merge architectural flexibility with structural reliability. We provide pre-finished painted steel, WPC panels, and stone-look textures that deliver exceptional UV and weather resistance for retail and corporate headquarters.
Selecting the right core insulation is critical to the thermal and structural performance of an exterior wall. The table below compares the performance profiles of common sandwich panel core materials supplied by Tangshan Haofa and our manufacturing network:
| Insulation Core Type | Density (kg/m³) | Thermal Conductivity (W/m·K) | Fire Reaction Class (EN 13501-1) | Water Absorption (%) | Primary Industrial Use Case |
|---|---|---|---|---|---|
| PIR (Polyisocyanurate) | 38 - 42 | 0.020 - 0.022 | B-s1, d0 (Flame Retardant) | < 1.0% | Cold Storage, Data Centers, Logistics |
| PUR (Polyurethane) | 35 - 40 | 0.022 - 0.024 | B-s2, d0 | < 1.5% | Standard Industrial Warehousing |
| Structural Rockwool | 100 - 120 | 0.038 - 0.044 | Class A1 (Non-Combustible) | < 2.0% | High-rise Firewalls, High-temp Plants |
| EPS (Expanded Polystyrene) | 15 - 25 | 0.033 - 0.038 | Class E | < 3.0% | Low-cost Commercial Partitions |
| XPS (Extruded Polystyrene) | 30 - 35 | 0.029 - 0.032 | Class E / B1 Custom | < 0.5% | Below-Grade Walls, Humid Enclosures |
