Does the fire bridge have to be a fireproof bridge?

Fire protection cable trays do not necessarily have to be fire-resistant, but fire-resistant cable trays can better protect cables and wires from damage in the event of a fire, thereby reducing losses caused by the fire. In the fire protection system of buildings, cable trays are usually used to install and protect cables and wires so that they can function properly in the event of a fire. Due to the high temperature, thick smoke, and toxic gases generated by fires, the design of fire-resistant cable trays can better withstand high temperatures and protect cables and wires. Fireproof cable trays are usually made of metal materials, such as galvanized steel or aluminum alloy, which can provide better high temperature resistance and protection performance. In addition, fire-resistant cable trays can also improve their fire resistance by coating them with fire-resistant coatings to provide better protection. However, even with the use of fire-resistant cable trays, other measures still need to be taken to ensure the safety and reliability of the fire protection system. For example, cables and wires should be regularly inspected and maintained to ensure they are not damaged or aged, and appropriate detectors should be installed to detect fires and activate emergency alarm systems. In short, although fire protection cable trays do not necessarily have to be fire-resistant, the use of fire-resistant cable trays can improve the reliability and safety of the fire protection system, and reduce the losses caused by fires.
