We use our own steel materials or famous brands according to clients demands. For polyurethane core materials, we use a stable and reliable raw material system and strictly control material quality based on product specifications.
Imported Production Equipment
Our production uses Italian high-pressure foaming equipment together with advanced continuous production lines in China. Production parameters such as foam density and bonding strength are strictly controlled to ensure stable production and consistent panel performance.
Experienced Production Team
Our workers have many years of experience in color-coated steel and sandwich panel production. They understand different materials, specifications, and production processes, and follow production standards and project requirements throughout the process.
ISO Quality Management
We follow ISO quality management standards throughout production and daily operations. Clear quality control procedures are applied from incoming raw materials to production and final inspection.
Strict Final Inspection
Every batch is inspected before shipment. We check key items including dimensions, thickness, appearance, bonding performance, and other required technical specifications to make sure the products meet the order and project requirements.
Experience with Large Projects
Our products have been used in industrial buildings, logistics and warehousing facilities, public buildings, and other large projects. This project experience gives us a better understanding of the actual requirements for materials, structures, installation, and supporting products.
