Trusted HEADSTREAM Sandwich Panels

Carefully examining the raw material—color steel coils. These coils, typically made of coated steel, are checked for surface quality, thickness, and uniformity to ensure they meet the requirements for durability and aesthetics in the final product.

The inspected steel coils are then unrolled and fed into a machine that strengthens and shapes them. Rollers press the steel into specific profiles, such as corrugated or flat patterns, enhancing structural integrity and preparing it for the sandwich panel's outer layers.

A core insulating material, often polyurethane or polystyrene, is prepared by mixing chemical components. This mixture is injected or poured between two steel layers, where it expands and hardens, forming a lightweight yet strong insulating core that defines the panel’s thermal and acoustic properties.

The assembled layers enter a dual-track system. This continuous molding process applies pressure and heat, ensuring the core Ascertaining the core adheres uniformly to the steel, creating a solid, cohesive panel as it moves along the production line.

Once molded, the panels are cut to precise lengths using automated saws or shears. The freshly cut panels are then air-dried or cooled, allowing the core material to fully set and stabilize, ensuring the panel's strength and dimensional accuracy.

Finally, the finished panels are stacked, wrapped, and secured with protective materials to prevent damage during transport. They are then labeled to ensure traceability from factory to construction site.
