FAQ — Sandwich Panels

Q: Is “sandwhich panels” wrong spelling?

A: Yes — correct: sandwich panels, but both appear in real searches.

Q: Export service available?

A: Yes — global shipping support.

Q: Lead time?

A: 10–20 days depending on color and area.

Q：How long do sandwich panels last?

A：High-quality sandwich panels with PU, PIR, or Rock Wool cores typically last 25–35 years with minimal maintenance. Their outer metal skins are coated with anti-corrosion paint such as PVDF or Polyester, which provides long-term UV and salt-spray resistance — ideal for coastal climates.According to Building Envelope Engineering (Elsevier 2023), optimized façade systems retain structural integrity for over 30 years.

Q：Are sandwich panels eco-friendly?

A：Yes. Sandwich panel construction reduces CO₂ emissions by up to 30 %, due to lower steel usage and improved energy efficiency. The cores are recyclable and CFC-free, meeting EU Ecodesign requirements (2025). When used in prefab systems, they cut on-site waste by 90 % and enable easy dismantling and reuse.

Q：What are sandwich panels used for in construction?

Sandwich panels are used in steel structure buildings, warehouses, cold rooms, modular homes, and clean rooms. They provide thermal insulation, weather protection, and structural strength in one prefabricated unit. Because each panel includes a metal skin and an insulated core, it reduces on-site labor time by up to 70% compared with masonry.Source: Prefabricated Construction 2025, RIBA Publishing
