Epoxy resin composite bridge beam

Specific characteristics of composite epoxy resin bridge beams: These bridge beams are highly flame-retardant, feature ample effective space, are aesthetically pleasing, and have excellent corrosion resistance. Their lifespan exceeds 30 years. Such products have been in use in the Chinese market for over 15 years without showing signs of fading or aging. Traditional metal bridge beams have a thin protective coating, which is prone to damage during transportation and installation, and the surface has microscopic pores through which corrosive gases can penetrate, affecting the corrosion resistance. Non-metallic cable bridge beams have stronger corrosion resistance but lack mechanical strength. However, if a metal frame is added to the composite epoxy resin cable bridge beams, they retain the original characteristics and enhance mechanical strength, capable of supporting large-diameter cables with spans up to 15 meters. Moreover, the bridge beams are pressure-molded with a protective layer that offers special functions like resistance to sunlight, solving issues of easy powdering and aging. For construction purposes, the corrosion resistance of composite materials primarily depends on the corrosion resistance of the high polymer materials within them.
