The steel skeleton is mainly made of high-quality cold-rolled plate by mechanical processing, which has the characteristics of high carrying capacity and long service life. The section of the steel skeleton shall be neat without burrs and sharp corners, and the groove shall be smooth and flat without sharp protrusions. After processing, the shape of the section is uniform, without bending, twisting, cracks, edges and other defects.
Fire cable tray is no stranger to us, about the performance of fire cable tray to do an understanding:
Fireproof cable tray is suitable for 10KV power cables, as well as control cables, lighting wiring and other indoor and outdoor overhead cable trench, tunnel laying, but many people may not know much about its fire performance;
The steel skeleton is mainly made of high-quality cold-rolled plate by mechanical processing, which has the characteristics of high carrying capacity and long service life. The section of the steel skeleton shall be neat without burrs and sharp corners, and the groove shall be smooth and flat without sharp protrusions. After processing, the shape of the section is uniform, without bending, twisting, cracks, edges and other defects.
The fireproof board is made of siliceous materials and calcareous materials as the main raw materials, mixed with a certain proportion of fiber materials, lightweight aggregates, adhesives and chemical additives, and made by advanced autoclaving technology.
Fire retardant coating is an efficient steel structure protection products. It selects polymer synthetic resin as film-forming material, and is made of flame retardant, foaming agent, carbonization agent and high temperature refractory material. Under the condition of high temperature, the continuous foaming and expansion effect of the coating occurs, forming a flexible sponge like carbonized heat insulation layer, so that the bearing steel structure will not be softened and deformed sharply due to the action of high temperature flame, and the strength will not drop sharply. The exterior fireproof coating shall be sprayed evenly, bright and clean without obvious color difference. The inner layer is added with fireproof board or sprayed with fireproof coating, and the fireproof board and bridge are fixed reliably.
