Fire-retardant coating for steel structures


Steel Structure Fireproof Coating I. Product Introduction Steel structure fireproof coating is a specialized coating designed to enhance the fire resistance limit of steel structures. When applied to the surface of steel structures, it forms a fire-resistant and heat-insulating protective layer, which delays the temperature rise of steel in a fire, thereby improving the fire resistance limit of the steel structure. This coating is mainly divided into thick, thin, and ultra-thin types, with different coating thicknesses and fire resistance limits for each type. Product Features: Excellent Fire Resistance: Steel structure fireproof coating rapidly expands in a fire to form an insulating layer, effectively reducing the temperature of the steel structure's surface, thereby enhancing its fire resistance limit. After rigorous testing, the fire resistance time of the fireproof coating under various fire conditions can meet the standard requirements. Moderate Coating Thickness: Different types of fireproof coatings have varying coating thickness ranges to meet the needs of different applications. During construction, precise control of the coating thickness ensures that the fireproof coating's performance is fully utilized. Easy Application: Steel structure fireproof coating can be applied through various methods such as spraying and brushing, making operation simple and convenient. At the same time, the coating has a shorter drying time, which helps to improve construction efficiency. Scope of Application Bridge Engineering: As a vital component of transportation infrastructure, the safety of bridges is paramount. Steel structure fireproof coating can be applied to critical parts of bridges such as steel beams and steel columns to improve the bridge's fire resistance, ensuring the stability and safety of the bridge structure in the event of a fire. High-rise Buildings: Steel structures are widely used as load-bearing and supporting structures in high-rise buildings. In these buildings, steel structure fireproof coating can be extensively applied to steel columns, steel beams, and other parts of steel structures to enhance the overall fire resistance of the building, ensuring safe evacuation of personnel and smooth firefighting operations. Storage Facilities: In industries such as petroleum and chemical, storage facilities are often constructed from steel. When these facilities store flammable and explosive materials, the consequences of a fire could be disastrous. Therefore, applying fireproof coating to the steel surfaces of these facilities can effectively improve their fire resistance and reduce fire risks. IV.

    I. Product Introduction

    Steel structure fireproof coating is a special coating used to improve the fire resistance limit of steel structures. When applied to the surface of steel structures, it forms a fire-resistant, heat-insulating protective layer, which delays the temperature rise of steel in a fire, thereby improving the fire resistance limit of steel structures. This coating is mainly divided into thick, thin, and ultra-thin types, with different coating thicknesses and fire resistance limits for each type.

    • Product Features

    Excellent Fire Resistance

    Steel structure fireproof coating expands rapidly in a fire to form an insulating layer, effectively reducing the surface temperature of the steel structure, thereby improving its fire resistance limit. After rigorous testing, the fire resistance time of fireproof coatings under different fire conditions can meet the standard requirements.

    Moderate Coating Thickness Different types of fireproof coatings have different coating thickness ranges to meet the needs of various applications. During construction, precisely controlling the coating thickness ensures that the performance of the fireproof coating is fully realized.

    Easy to Apply Steel structure fireproof coating can be applied by various methods such as spraying and brushing, making operation simple and convenient. At the same time, the shorter drying time of the coating helps improve construction efficiency.

    • Scope of Application

    Bridge Engineering As a vital component of transportation infrastructure, the safety of bridges is paramount. Steel structure fireproof coating can be applied to critical parts of bridges such as steel beams and columns, enhancing the fire resistance of bridges and ensuring the stability and safety of the bridge structure in the event of a fire.

    High-rise Buildings In high-rise buildings, steel structures are extensively used as load-bearing and supporting structures. In these buildings, steel structure fireproof coating can be widely applied to steel columns, steel beams, Steel Structure Buildings and other parts, improving the overall fire resistance of the building and ensuring safe evacuation of personnel and smooth firefighting operations.

    Storage Equipment In industries such as petroleum and chemical, storage equipment often uses steel structures. If a fire occurs while these devices store flammable and explosive materials, the consequences would be unimaginable. Therefore, applying fireproof coating to the steel surfaces of these devices can effectively improve their fire resistance and reduce fire risks.
