1. Economic
Due to its light weight and large size, it usually takes 3-5 days for 2 workers to complete all the installation in a common residence. And it greatly reduces related costs in transport as well as application.
2. Easily installed
Lightness and easy-to-cut determine that it is widely used in various buildings, like steep roofs or high-rise building. Scientific and reasonable design make it much easier to install.
3. Wind resistance and storm resistance
Stone coated metal roof tile has only 1/6 of the weight of other traditional tiles, but the horizontal overlap design of each piece can resist cyclone and strong wind.
4. Heat insulation and durability
Alu-zinc steel plate has strong heat resistance, and stone chips coated design also insulates from heat when exposed to ultraviolet radiation. In addition, the lifespan of stone coated metal tile can be up to 50 years.
Raw Materials
GALVALUME STEEL
Coating composition is 55% aluminum in weight ratio (80% surface volume ratio), 43.4% zinc, and 1.6% silicon.
STONE CHIPS
All Forsetra® roof tiles are coated with natural stone chips, volcanically formed and taken from quarries in French and the most famous Chinese-brand of CG Rock only. We don't use any other fake stone chips from other factories which are cheap but lousy quality.
Main Products
Production Process
1. Decoiling and Cutting
- Decoiling: Use a decoiler to unwind the steel coils.
- Cutting: Feed the steel sheets into a cutting machine to get them to the required dimensions for the roof tiles.
2. Press Forming
- Press Machine: Pass the cut steel sheets through a press machine to form the desired tile shape. This step gives the tiles their structure and texture.
3. Cleaning and Priming
- Cleaning: Clean the formed steel sheets to remove any oil, dust, or contaminants.
- Priming: Apply a primer coating to the cleaned steel sheets to enhance adhesion of the stone granules and prevent corrosion.
4. Adhesive Coating
- Adhesive Application: Coat the primed steel sheets with an adhesive or base coat. This is typically an acrylic resin that will bond the stone granules to the steel surface.
5. Stone Coating
- Stone Granules Application: Sprinkle stone granules onto the adhesive-coated steel sheets. Ensure even coverage to achieve a uniform look and effective protection.
- Pressing Stone Granules: Pass the sheets through a rolling machine to press the stone granules firmly into the adhesive layer.
6. Curing
- Initial Curing: Allow the tiles to undergo an initial curing stage to set the adhesive and stone granules.
- Oven Curing: Transfer the tiles to a curing oven where they will be heated to a specified temperature to fully cure the coating, ensuring a strong bond and durability.
7. Finishing Coat
- Top Coat Application: Apply a top coat (clear acrylic or similar protective layer) over the stone granules. This enhances UV resistance, color stability, and weatherproofing.
- Final Curing: Allow the top coat to cure, ensuring it forms a robust protective layer over the tiles.
8. Quality Control
- Inspection: Conduct thorough quality checks to ensure the tiles meet required standards and specifications.
- Testing: Perform tests for adhesion, impact resistance, weather resistance, and color fastness.
9. Packaging and Storage
- Packaging: Pack the finished tiles carefully to avoid damage during transportation.
- Storage: Store the tiles in a dry, cool place until they are ready to be shipped.
