As an important facility for cable management in modern buildings, the fireproof performance of fireproof trough type bridge is directly related to the safety and stability of the building. This article will explore the main materials of fireproof trough type bridge and its excellent fireproof performance.The main materials of fireproof trough type bridge are varied and designed to meet the needs of different environments and applications. Common metal materials include galvanized steel, stainless steel and aluminum alloy. These metal materials have good strength and corrosion resistance. At the same time, through special fireproof treatment, such as coating fireproof coating, their fire resistance can be significantly improved. Galvanized steel sheet has become one of the preferred materials for fireproof bridges because of its low cost and good processing performance. Stainless steel is particularly outstanding in humid or corrosive environments due to its excellent corrosion resistance. Aluminum alloy is easy to transport and install because of its light weight and high strength.In addition to metal materials, fireproof trough type bridge also widely uses non-metallic materials, such as fiberglass and polymer materials. These materials not only have excellent fireproof performance, but also have good insulation and corrosion resistance. FRP has become another important choice for fireproof bridges with its high strength, light weight and easy molding. Polymer materials can maintain structural stability at high temperatures and effectively prevent the spread of fire through special fireproof formulas.In terms of fireproof performance, fireproof trough type bridge performs well. Its fireproof principle is mainly to use refractory materials to manufacture bridges and apply fireproof coatings on the surface of bridges to form a dense fireproof layer. This fireproof layer can effectively isolate oxygen and heat, slow down the spread of fire, and win precious time for personnel evacuation and fire rescue. According to the requirements of different places of use, fireproof trough type bridge can meet the requirements of first, second and third level fire resistance grades respectively, ensuring excellent fireproof effect in various fire scenarios.In addition, fireproof trough type bridge also has good bearing capacity and dustproof and anti-interference capabilities, which can protect cables from damage from the external environment and extend the service life of cables. Its simple structure and convenient installation greatly save construction time and cost.In summary, fireproof trough type bridge has become an indispensable safety facility in modern buildings with its diverse material selection and excellent fireproof performance. In the future development, with the continuous advancement of material science and fire protection technology, the fireproof performance and application scope of fireproof trough type bridge will be further improved and expanded.
