Color steel sandwich panel selection guide: Accurate matching based on temperature requirements and usage scenarios

Ⅰ.Basic knowledge of color steel sandwich panels

Color steel sandwich panels are composite panels with color coated steel plates as the surface layer and different core materials in the middle. They have the characteristics of light weight, high strength, thermal insulation, and fast construction. They are widely used in industrial plants, logistics warehousing, cold storage, clean workshops and other construction fields.

Ⅱ.Select color steel sandwich panels according to temperature requirements

1.Normal temperature environment (0℃-30℃)

---Recommended core material: polystyrene (EPS) sandwich panels

---Features:

Thermal conductivity is about 0.041W/(m·K)

Economical and cost-effective

Applicable to ordinary factories, warehouses, office partitions, etc.

Thickness recommendation: 50-100mm

2. Low temperature environment (-20℃-0℃)

---Recommended core material: polyurethane (PU) sandwich panel or extruded polystyrene (XPS) sandwich panel

---Features:

PU thermal conductivity 0.022-0.027W/(m·K)

XPS thermal conductivity 0.028-0.034W/(m·K)

Excellent moisture-proof performance and high compressive strength

Applicable to cold storage, cold chain logistics center, etc.

Thickness recommendation: 100-150mm

3. Ultra-low temperature environment (below -40℃)

---Recommended core material: polyurethane (PU) sandwich panel or PIR sandwich panel

---Features:

PIR thermal conductivity 0.021-0.023W/(m·K)

Excellent low temperature resistance

Fire rating up to B1

Suitable for quick freezing warehouses, polar research stations, etc.

Thickness recommendation: 150-200mm

4. High temperature environment (above 50℃)

---Recommended core material: rock wool sandwich panel or glass wool sandwich panel

---Features:

Rock wool temperature resistance up to 600℃

Glass wool temperature resistance about 250℃

Class A fireproof, non-combustible material

Suitable for high temperature workshops, boiler rooms, drying rooms, etc.

Thickness recommendation: 75-150mm.

Ⅲ.Choose color steel sandwich panels according to the usage scenario

1.Industrial plant

1) Recommended choice: EPS or rock wool sandwich panels

2) Considerations:

Taking into account both insulation and cost

Choose rock wool in areas with high fire protection requirements

Thickness is usually around 100mm

2. Logistics and warehousing

1) Recommended choice: EPS or PU sandwich panels

2) Considerations:

Strength should be considered for large-span structures

PU panels should be used for cold chain logistics

Pay attention to moisture-proof performance

3. Clean workshop

1) Recommended choice: medical-grade PU sandwich panels

2) Considerations:

Antibacterial surface treatment

Dust-free sealing performance

Rounded corner design for easy cleaning

4. Mobile houses

1) Recommended choice: lightweight EPS sandwich panels

2) Considerations:

Lightweight for easy transportation

Quick disassembly and assembly structure

Thickness is usually 50-75mm

5. Special environment

---Corrosive environment: choose galvanized aluminum plate surface + PU core material

---High humidity environment: choose XPS or PU board with ---moisture-proof film

---High noise environment: choose glass wool sandwich panel (good sound insulation performance)

Ⅳ. Other key factors for choosing color steel sandwich panels

• Fireproof grade: Choose Class A (rock wool) or Class B (organic material) according to the building fire protection requirements

2. Strength requirements: Large-span buildings need to choose high-density core materials or increase the thickness of steel plates

3. Durability: It is recommended to choose aluminum-zinc plate in coastal areas (corrosion resistance is better than galvanized plate)

4. Environmental performance: The medical food industry needs to pay attention to the environmental certification of core materials

5. Aesthetic requirements: Choose different colors and surface textures according to the architectural style

V. Professional suggestions

1. PU/PIR boards are recommended for cold areas in the north, and XPS boards can be considered for hot and humid areas in the south

2. Areas with large temperature differences should choose core materials with small thermal expansion and contraction coefficients

3. Professional cold storage recommends double-sided stainless steel color steel plates + PU core materials

4. For special projects, customized composite sandwich panel solutions can be considered.

By scientifically selecting color steel sandwich panels suitable for temperature requirements and usage scenarios, it can not only meet the functional requirements of the building, but also achieve energy savings and cost optimization, creating maximum value for the project.
