Product Details
1. Product Introduction
Our wall sandwich panels are designed to provide excellent insulation, structural strength, and long-term durability for industrial and commercial wall systems.
These panels are manufactured using high-density PU PIR EPS or rock wool cores combined with galvanized or pre-painted steel sheets to achieve high fire resistance, low thermal conductivity, and superior energy efficiency.
As a professional wall sandwich panel manufacturer, we ensure strict quality standards, consistent density control, smooth panel surface, and high bonding strength.
Our panels are widely used in warehouses, logistics centers, cold storage rooms, clean rooms, commercial buildings, and modular housing projects.
The tongue-and-groove or concealed-fix joint systems allow for fast installation and strong airtightness, reducing labor and construction time.
