Embossed Hot-dip Galvanized Steel Coil, Weather-resistant Galvanized Steel Sheet Specially Used For Railway Stations

The common carbon steel plates commonly used in traditional railway station buildings are prone to rusting and deformation, requiring frequent maintenance and incurring high costs. Ordinary color steel plates have the drawbacks of insufficient weather resistance and weak wind-breaking capacity, making them unable to withstand the challenges of extreme weather conditions. Our company has developed embossed hot-dip galvanized steel coils to address these issues. Through advanced production techniques, it achieves a balance between anti-corrosion performance, structural strength, and processing performance. The product features a continuous hot-dip galvanized layer as the core protective system, combined with the three-dimensional texture formed by surface embossing. It not only possesses the high strength characteristics of metal materials but also has excellent decorative effects. It can be directly used in building enclosure structures without the need for additional complex processing, significantly shortening the construction period and reducing the total life cycle cost.

The corrosion resistance of embossed hot-dip galvanized steel coils is attributed to the dual protection mechanism of the zinc layer. The dense zinc layer acts as a physical barrier, effectively preventing moisture, oxygen, and corrosive media from coming into contact with the steel substrate. At the same time, the electrochemical sacrificial protection effect of zinc can automatically repair the protective layer when there are minor scratches on the surface of the sheet. Depending on the usage environment, the zinc layer thickness can be customized from 40 to 275 g/㎡. Its atmospheric corrosion performance is significantly superior to that of ordinary hot-rolled steel plates. It can maintain a stable state in industrial pollution areas and coastal high-salt spray environments for a long time, significantly reducing the later maintenance investment for buildings with high maintenance difficulty such as railway stations.

Surface embossing treatment not only enhances the appearance of the sheet but also effectively improves the overall stiffness and buckling resistance of the sheet, enabling it to withstand the load requirements of large-span roofs and large areas of walls in railway stations. It also has excellent wind resistance and seismic performance, capable of withstanding extreme weather conditions such as strong winds and heavy rain, ensuring the safety of the building structure.

This material has excellent processing and forming performance, supporting various processing methods such as bending, rolling, stamping, and shearing. During the processing, the zinc layer will not crack or fall off. This characteristic enables it to perfectly adapt to the complex architectural design of railway stations, fitting precisely and installing accurately in various curved roofs, irregular walls, and corner areas, meeting the needs of different architectural styles.

Embossed hot-dip galvanized steel coils are non-flammable materials and comply with various building fire protection regulations. They are particularly suitable for railway stations, which are public buildings with a high density of people. At the same time, the material surface has good thermal reflection performance, which can effectively reduce the absorption of solar radiation heat by the building, lower the cooling energy consumption in indoor spaces such as waiting halls, and achieve energy conservation and reduction. The raw materials and production process of the product comply with international environmental protection standards, are 100% recyclable, have no heavy metal pollution, and are in line with the development concept of green buildings.

Flowered hot-dip galvanized steel coils have extensive applications in the construction of railway stations, covering all the protective parts of the building. When used in the roof system, their lightweight feature can significantly reduce the load of the roof structure, and together with the waterproof system formed by the dedicated accessories, it can effectively solve the leakage problem of the large-span roof of the railway station. At the same time, its excellent wind resistance and shedding performance can ensure the safety of the roof in extreme weather conditions. When used for wall protection, the diverse patterns of the pressed steel can enhance the aesthetic appeal of the building's exterior facade. The board's shock resistance and easy cleaning properties also facilitate later maintenance, keeping the building's appearance clean.

The platform canopy is an important component of the railway station. The high strength and weather resistance of the pressed hot-dip galvanized steel coils make them an ideal material for the roof and enclosure of the canopy, capable of enduring the sun and rain without damage for a long time. Moreover, the construction is convenient and can quickly complete large-scale installation. In addition, this material can also be used for the partitions of the waiting hall in the railway station, the enclosure of equipment rooms, ventilation ducts, sign support brackets and other auxiliary facilities. With its good processing performance, it can be made into various shapes of components to meet the usage requirements of different functional areas.

To ensure the stability of the quality of each batch of products, our company has established a strict full-process production control system. When raw materials enter the factory, comprehensive inspections will be conducted on the material and mechanical properties of the hot-rolled steel coils. Only those that meet the standards can proceed to the production process. Subsequently, the coils are unwound and pre-treated. Through degreasing and rust removal processes, the oil stains and oxide scales on the base material's surface are completely removed to ensure the adhesion between the zinc layer and the steel base.

Before the finished products are shipped out, they will undergo strict quality inspections covering various indicators such as size accuracy, zinc layer thickness, surface quality, mechanical properties, and salt spray corrosion tests. Only those products that pass all the inspections can be packaged and dispatched, ensuring that each roll of steel plate delivered to the customers meets the project requirements.

Our company adopts professional export packaging solutions to ensure that the products are not damaged during long-distance transportation. The standard packaging involves tightly wrapping the steel coils with waterproof and moisture-proof paper, then using high-strength steel straps for multiple layers of bundling and fixation. The entire package is placed on a sturdy wooden pallet, effectively preventing collisions, scratches and moisture absorption during transportation. For small batch orders, packaging specifications can be adjusted according to customer requirements, making it convenient for on-site handling and storage.

The delivery cycle is adjusted flexibly according to the order quantity. Regular orders can be completed and shipped within 7-15 days. Production can be planned in advance based on the project construction schedule to ensure that materials arrive on time. The products are mainly shipped from Qingdao Port and Tianjin Port in China. These two ports are major international trade hubs, with shipping routes covering all over the world, providing efficient and economical logistics solutions. The regular minimum order quantity is 3-5 tons. For trial orders from new customers, the order quantity can be negotiated to facilitate customers' quality testing.
