Advanced Manufacturing Process

Surface Preparation

The metal sheets undergo extensive cleaning using chemical solutions or abrasive methods to ensure a contaminant-free surface.

Coating Application

Roll Coating: The sheets are coated using a roll coating method, ensuring consistency and even application across large surfaces.

Curing Process: After coating, the sheets are heated in an oven, allowing the paint to cure and bond effectively to the metal substrate.

Profiling

The trapezoidal shape is achieved through a process of cold forming, which enhances the structural strength of the sheets.

Quality Assurance

Tests for adhesion, thickness, and color consistency are performed, ensuring that the sheets meet strict industry standards.

Enhanced Properties

Thermal Efficiency

The reflective surface reduces heat absorption, leading to lower energy costs for cooling during hot months.

Some coatings are designed to meet Energy Star standards, enhancing energy efficiency in buildings.

Sound Insulation

The design and materials can provide sound insulation benefits, making them suitable for noise-sensitive areas.

Fire Resistance

Galvalume sheets exhibit non-combustible properties, adding a layer of fire safety to building designs.

Quality Control

Inspection: Rigorous quality control checks are performed throughout the manufacturing process, including:

Thickness measurements of the metal and paint layers.

Adhesion tests to ensure the paint adheres properly to the substrate.

Visual inspections for surface defects, color consistency, and overall finish quality.

Testing: Additional tests may be conducted to assess corrosion resistance, weathering, and UV exposure, ensuring that the product meets industry standards.
