- Main material:?Steel (such as cold-rolled steel) is usually used as the framework, providing high strength and load-bearing capacity to support cable weight and withstand external forces.
- Fireproof coating:?The surface is sprayed with fireproof paint, generally composed of polymer synthetic resin as the film-forming material, with flame retardants, foaming agents, carbonizing agents, and high-temperature refractory materials added.
- Structural design:?Various configurations are available according to needs, such as common ladder-type and tray-type designs, facilitating cable installation and organization. Some models include covers to form closed or semi-closed structures, enhancing fire protection and cable protection.
- Multiple sizes:?Width, height, and length can be customized according to project requirements. Common widths include 200mm, 300mm, 400mm; common heights include 100mm, 150mm, 200mm; standard lengths are 2m, 3m, 6m, with non-standard lengths available upon request.
- Hole diameter and spacing:?For ladder-type racks, reasonable rungs spacing and side plate hole design ensure cable support and fixation while facilitating ventilation and cable installation.
- Excellent fire resistance:?When exposed to fire, the coating undergoes continuous foaming and expansion, forming a flexible sponge-like carbonized insulation layer that effectively blocks heat transfer, delays steel structure deformation, and prevents fire spread, allowing cables to function normally for a certain period to facilitate evacuation and rescue. Coating thickness varies by fire rating: approximately 0.4-0.6mm for 0.5-hour resistance and 1.8-2.0mm for 2-hour resistance.
- High mechanical strength:?Steel framework provides excellent strength and rigidity to withstand cable weight and installation/maintenance forces without deformation, suitable for various installation environments.
- Good corrosion resistance:?With galvanized pretreatment plus fireproof coating, the product resists corrosion in humid and mildly corrosive environments, extending service life and reducing maintenance costs.
- Easy installation:?Rational design with simple connection methods (bolts, snaps) facilitates on-site assembly and disassembly, improving construction efficiency. Flexible layout accommodates various building structures and cable routing requirements.
- Attractive appearance:?The fireproof coating creates a smooth, flat surface.
