#Installation Establishment# specializes in designing and installing sandwich panels at very competitive prices. The sandwich panel consists of galvanized sheet metal on both sides. The installation process begins by creating the iron frame with square dividers of sizes (40-80) and a thickness of 2.5 mm, and 12 mm long screws, galvanized and corrosion-resistant. Gutters are also installed to effectively drain rainwater from the roofs. After completing the sandwich panel installation, we will seal the openings using specialized materials such as German foam and silicone. The sandwich panel surface will be tested to ensure there are no water leaks, and we will spray water on the surface to detect any remaining gaps and seal them using materials like German foam and silicone.
