Fire-resistant bridge supports are treated with a fire-retardant paint on their surface to provide fire prevention and retardant properties. In reality, the bridge support itself won't catch fire; it's only the cables that could potentially ignite. The fire-retardant paint works by preventing the spread of fire, offering excellent fire-resistant qualities. It is also resistant to heat, oil, corrosion, is non-toxic, and environmentally friendly. The overall installation is convenient, the structure is reasonable, the service life is long, and it is aesthetically pleasing. Cables installed in the bridge support are in a tidy environment, making cleaning easy. The fire-resistant coatings are characterized by thin layers, high耐火limits, and strong adhesion.


Standard cable tray or fire-resistant cable tray with fire-resistant shell and layer, coated with fire-retardant paint, effectively isolates air and achieves heat insulation. It ensures that the fire's heat energy does not reach the interior within the specified time, allowing the fire-resistant cable tray to operate normally. Additionally, using high environmental-friendly pigments, the fire-retardant paint on the bridge is non-toxic, non-polluting, fireproof, waterproof, and oil-resistant. Generally used for laying: power cables, communication signal cables, etc.
Fire-resistant bridge's fire-resistant performance:
Fire-resistant bridge trays should comply with the following standards: JB/T 10216-2013 "Cable Trays for Electric Control and Distribution," GB 8624-2012 "Classification of Ignitability of Building Materials and Products," and CECS24:90 "Technical Specification for the Use of Fire-retardant Coatings on Steel Structures."
Fire-resistant bridge supports differ from standard bridge supports in their application environments:
Fire-resistant ladder usage environment: In the project, the fire protection engineering section requires fireproofing for fire equipment power lines, etc. The fire-resistant ladder meets this fireproofing requirement, featuring a frost-like fire-resistant paint layer on the surface, which provides fireproofing, heat insulation, and flame-retardant effects.
2. Standard Bridgeway Usage Environment: Steel galvanized cable bridgeways are primarily used for installation in indoor dry conditions. Galvanizing, also known as "electro-galvanized/cold galvanized," offers slightly less corrosion resistance compared to other bridgeway materials. However, installing a standard steel galvanized bridgeway indoors in a dry environment is sufficient to meet corrosion protection requirements, as galvanized bridgeways are cost-effective.
