Frequently Asked Questions (FAQ)
- Q1: What is the typical weight of a 20mm EPS sandwich panel?
- A: The weight is approximately 12-14 kg per square meter, depending on the steel gauge and core density. This lightweight characteristic makes transportation and installation easy.
- Q2: Can these panels be used for load-bearing walls?
- A: The panels are designed for non-structural exterior walls and partitions. For load-bearing applications, additional structural framing is required.
- Q3: What fire rating do these panels have?
- A: Standard EPS panels are combustible. However, we offer fire-retardant EPS (FR grade) and optional fireproof coating to meet specific fire safety requirements. Please consult with our sales team for details.
- Q4: How do you install the panel?
- A: Installation typically involves fastening the panels to a steel or concrete substructure using screws. The panels feature a tongue-and-groove joint for a tight seal. Detailed installation manuals are provided upon request.
- Q5: What is the expected lifespan of the panel?
- A: With proper installation and maintenance, the panels can last 20-30 years or more. The metal surface is corrosion-resistant, and the EPS core does not degrade over time.
- Q6: Can I get samples before placing a bulk order?
- A: Yes, we can provide small samples (e.g., 300x300 mm) for evaluation. Please contact our sales team to arrange shipping.
- Q7: Are the panels suitable for cold storage?
- A: Yes, the EPS core provides excellent thermal insulation. For cold storage applications, we recommend using thicker panels (e.g., 50-100 mm) for better performance. The 20mm panel is more suitable for moderate insulation needs.
- Q8: What certifications do your products hold?
- A: Our production facility is ISO9001 certified. We also comply with various international standards and can provide test reports for thermal conductivity, density, and other parameters upon request.
