Transportation, Storage, and Installation Precautions for Stone Coated Metal Roof Tiles

Following the correct procedures during the transportation, storage, and installation of stone coated metal roof tiles is key to ensuring product quality and extending its lifespan. Whether it’s transportation from the factory to the construction site, the selection of storage environments, or the operational norms during installation, any mistake in these stages could affect the performance and appearance of stone coated metal roof tiles. Therefore, understanding and adhering to the precautions in these three aspects can not only prevent unnecessary losses but also lay a solid foundation for the smooth progress of the project.

In the process of transporting stone coated metal roof tiles, the quality and method of packaging are crucial for protecting the products. To ensure that the tiles are not damaged during long-distance transportation, AttiRoof carefully carries out the following packaging operations for each batch of tiles:

Packages for Stone Coated Metal Roof Tiles

1. Fumigated Wooden Pallets

Fumigated wooden pallets effectively eliminate potential pests, eggs, or fungi, preventing the spread of pests during international transportation. The pallets are sturdy and durable, capable of supporting heavy loads. stone coated metal roof tiles is relatively heavy, and using wooden pallets ensures the stability of the goods during transportation, reducing the risk of pallet breakage or goods shifting. They comply with ISPM 15 international standards and can be reused and recycled.

2. Bubble Wrap Layering

The surface of stone coated metal roof tiles is delicate, especially the colored sand layer, which is prone to damage from friction. Bubble wrap is soft and provides cushioning, creating a good buffer that can effectively absorb the shocks and vibrations generated during transportation. Moreover, bubble wrap offers some moisture resistance, isolating humidity and preventing damage or fading of the colored sand layer due to a damp environment.

3. Cardboard Protection and Strap Securing

Wrapping the goods with cardboard around the sides and securing them with straps can effectively bind all the tiles together into a solid structure. Straps ensure that the  stone coated metal roof tiles does not loosen or shift during transportation, especially on long journeys, keeping the pallet stable. The cardboard wrapping provides an additional protective layer, absorbing and distributing external impacts, preventing damage from handling or transportation collisions.

4. Steel Edge Protection

The edges and corners of stone coated metal roof tiles are usually the most vulnerable areas, prone to damage during handling and stacking. By wrapping the edges with 0.4-0.5mm thick steel edge protectors, the tiles receive additional protection, reducing the likelihood of collisions and wear.

5. Plastic Film Sealing

One of the greatest advantages of plastic film is its excellent waterproof and moisture-proof performance. By sealing the stone coated metal roof tiles with plastic film, external moisture and water can be effectively kept out, preventing the tiles from becoming damp or corroded during transportation or storage, especially important during sea shipping or when stored in humid warehouses. The film also provides a barrier against dust, dirt, and other contaminants, ensuring the product remains clean. It blocks wind and sand, protecting the surface of the tiles and preventing the colored sand from getting polluted or damaged.

Protection Measures Inside the Container

1. Iron Frames

The use of iron frames provides a stable protective structure between the goods and the walls of the container, reducing the risk of the cargo shifting due to sudden braking or bumps during transportation, thus preventing accidents. Additionally, the frames allow the cargo to be stacked vertically, optimizing the vertical space in the container, increasing the load capacity, and improving space utilization.

2. Airbags

Airbags can fill the gaps between the cargo and the container, further preventing the goods from sliding or shifting during transportation, ensuring the overall stability of the load. Airbags can also fill irregular gaps, preventing wasted space or the collapse of improperly stacked goods. This not only improves loading efficiency but also reduces transportation costs.

1. Stone-coated metal roof tiles should be placed in a cool and well-ventilated environment or stored outdoors. Sleepers should be placed underneath the tiles as a cushion, and the tiles should be stacked on top to maintain proper horizontal spacing. It is particularly important to ensure good ventilation and avoid placing the tiles directly on the ground to prevent moisture from affecting them.

2. Avoid placina them in areas contaminated by sand or dustAccumulation of sand or dust on the stone coated metal roof tiles will affect the initiaappearance when they are first laid.

3. In case of rain or water exposure, the packaging should beopened immediately to allow for ventilation and drying.Avoidcorrosion and alkalinization reactions caused by covering ancsealing.

   
   

To ensure the long-term performance and durability of stone coated metal roof tiles, it is essential to follow proper installation procedures. Below are the key precautions to keep in mind during the installation of stone coated roofing sheets:

 Purlin Spacing

· For single-tile stone coated metal roof tiles, the recommended purlin spacing is 370mm.

· For Long Span Stone coated Roof sheets, the suggested purlin spacing ranges from 1 to 2 pitches (between 300mm to 800mm).

· Single-tile stone coated metal roof tiles: Use approximately 10-14 screws or nails per square meter.

· Long Span Stone coated Roof sheets: Use approximately 8-12 sets of screws or nails per square meter.

· Important Note: For steel purlins, use self-tapping screws; for wooden purlins, use steel nails.

Roof Slope

The slope of the roof should not be too shallow. A minimum slope of 12 degrees is recommended to ensure proper drainage and performance of stone coated metal roof tiles.

Tile and Accessory Overlap

When installing stone coated metal roof tiles and coordinating accessories or decorative parts, the overlap between them must be tight and flush, with no visible gaps or unevenness. After installation, the nail holes should be filled with acrylic resin sealant and then sprinkled with colored sand to protect the area and ensure waterproofing. If any special shapes require cutting of stone coated metal roof tiles, make sure the cut edges are treated with an anti-corrosion coating to prevent rust from forming at the cutting sites.

Safety and Walking on the Roof

Construction workers should wear soft rubber-soled shoes while installing stone coated metal roof tiles. Avoid wearing hard-soled shoes or leather shoes. When walking on the tiles, workers should step on the overlap areas between the valleys of the tiles and the purlins rather than directly on the tiles themselves. It is strictly prohibited to jump, stomp, or hit the surface of stone coated metal roof tiles during installation.

By following these installation guidelines, you can ensure the longevity, aesthetics, and weather resistance of stone coated metal roof tiles in your roofing projects.

The transportation, storage, and installation of stone coated metal roof tiles are critical processes that directly impact the product's performance, appearance, and longevity. By adhering to proper procedures and guidelines at each stage, you can ensure the tiles are protected from damage and maintain their quality.

During transportation, key protective measures include using fumigated wooden pallets, bubble wrap, cardboard protection, steel edge protectors, and plastic film sealing to prevent damage from shocks, moisture, or contaminants. Additionally, the use of iron frames and airbags inside shipping containers helps optimize space and reduce the risk of cargo movement during transport.

For storage, the tiles should be kept in a cool, ventilated environment, with appropriate spacing to avoid dampness and dust contamination. Proper ventilation is crucial to prevent corrosion, especially after exposure to rain or water.

In terms of installation, it is vital to follow correct purlin spacing, ensure tight overlaps between tiles and accessories, and use the appropriate type and number of screws or nails. Roof slope is also important to ensure effective drainage. Additionally, special care must be taken during installation, such as sealing nail holes and treating cut edges for corrosion protection, while workers must observe safety protocols to avoid damaging the tiles.

By carefully following these precautions, you can maximize the durability, aesthetic appeal, and weather resistance of stone coated metal roof tiles, contributing to the overall success of any roofing project.
