Common thermal insulation materials for sandwich panels include rock wool, expanded polystyrene (EPS), and polyurethane, which have low thermal conductivity, thereby providing excellent thermal insulation for mobile housing, integrated houses, and steel structure workshops. High-strength colored steel panels are made from high-strength steel sheets (tensile strength of 5600 kg/cm) combined with advanced design and rolling molding. This is why colored steel panel mobile houses possess structural characteristics.
1. Color steel sandwich panels, commonly featuring a tongue-and-groove insertion design, offer the advantages of easy installation, time and material savings, good flatness, and high strength, making them particularly suitable for ceiling and partition systems.
2. Thickness (mm): 50-250
3. Length (mm): Due to continuous molding production, the board length can be determined according to customer requirements.
4. Width (mm): 1150 (1200) (960) (950)
5. Core Material Performance:
Polystyrene Volume Density: ≥15 kg/m³; Thermal Conductivity: ≤0.036 W/m.K; High Operating Temperature: Approximately 100 °C
B. Rock wool bulk density: ≥120 kg/m³, thermal conductivity: ≤0.043 W/m.K, high operating temperature: approx. 500 °C, A|Non-flammability: B1 grade, Non-flammability: A grade
The 950-watt corrugated color steel sandwich panel integrates both corrugated and sandwich panels, offering three times the strength of traditional flat color steel sandwich panels. It utilizes concealed self-drilling screws for connection with the roof truss, preserving the exposed part of the color coated steel without damage, thereby extending the lifespan of the color steel sandwich panel. The interlocking of panels is designed with a cap-style connection, facilitating construction and increasing efficiency, with the added feature of being water-resistant.
2. Rock wool sandwich panels are made with basalt and other natural ores as the main raw materials, which are melted at high temperatures to form fibers, mixed with an appropriate amount of binder, and then solidified and processed. This product is suitable for insulation and soundproofing in industrial equipment, buildings, and ships, as well as for ceilings and partitions in clean rooms, explosion-proof and fire-resistant rooms.
3. The PU polyurethane sandwich panel has a bonding strength of not less than 0.09 MPa, the combustion performance reaches B1 level, and the bending capacity of the sandwich panel is not less than 0.5 kN/m² when the deflection of the sandwich panel is Lo/200 (Lo being the distance between supports).
