The "NS Cover Plate" is a lightweight exterior material for bridges, composed of a metal sandwich panel made up of three layers: inner material, core material, and outer material, combined with the necessary prescribed support materials for installation on the main structure. This product protects bridges on main roads, railways, and at sea from deterioration factors such as wind, rain, sunlight, and salt, contributing not only to extended lifespan but also serving as a permanent scaffold that allows for safe and reliable close visual inspections. By leveraging the characteristics of the metal sandwich panel, it offers sound insulation and the ability to freely choose colors, thereby contributing to the enhancement of the surrounding environment without compromising aesthetics. It is a product that can be called a trump card for durable and economical preventive maintenance of bridges, regardless of whether they are newly constructed or existing. 【Features】 - "Permanent scaffold function" allowing for inspections and repairs at any time - "Aesthetic function" that upgrades the appearance of the bridge through free color selection - "Corrosion protection function" that protects steel girders from corrosive factors - "Third-party damage prevention function" against concrete spalling of the deck slab - "Fire protection function" that safeguards bridge girders from fires below - "Sound insulation function" that prevents noise generated by traffic and construction from leaking outside - "Flat floor" applicable to walking surfaces - "Sound-absorbing function panel" that can also absorb traffic noise from below the girders

In the bridge and infrastructure industry, there is a demand for improving the durability of structures and enhancing the efficiency of maintenance management. In particular, deterioration caused by external environmental factors such as wind, rain, sunlight, and salt is a significant challenge that hinders the longevity of bridges. Protecting bridges from these deterioration factors and enabling safe and reliable inspections are essential for the sustainable maintenance of infrastructure. Our "NS Cover Plate" is a product developed to address these challenges. 【Usage Scenarios】 - Bridges on main roads, railways, and over the sea - Preventive maintenance for new and existing bridges - Enhancing the aesthetic appearance and longevity of bridges - Improving the efficiency of close visual inspections 【Benefits of Implementation】 - Reduction of maintenance management costs due to the longevity of bridges - Protection of steel girders from wind, rain, sunlight, and salt - Realization of safe and reliable close visual inspections - Improvement of landscape through the aesthetic enhancement of bridge appearances - Prevention of third-party damage in the event of concrete spalling from the deck slab

In port facilities, corrosion caused by harsh environmental factors such as salt and wind-driven rain poses challenges for the longevity and maintenance of the structures. In particular, salt damage can accelerate the deterioration of steel materials, potentially affecting the safety of the structures. In response to these challenges, our "NS Cover Plate" protects steel beams with its excellent corrosion resistance, contributing to the longevity of the facilities. Additionally, it functions as a permanent scaffold, enabling safe and reliable close visual inspections. 【Usage Scenarios】 - Coastal bridges and piers - Infrastructure facilities located in salt-damaged areas - Structures requiring regular inspections and repairs
