Product Name: Corrugated Metal Pipe Culvert/Large Diameter Galvanized Corrugated Culverts
Galvanized Corrugated Steel Pipe culvert has excellent abrasion and corrosion resistance.
Corrugated culvert steel corrugated culvert pipe anticorrosion:
The first is the hot-dip galvanizing of corrugated culvert pipes. The theoretical service life of corrugated culvert pipes is about 100 years. In order to achieve a better anti-corrosion effect, we spray asphalt on the inner and outer walls of corrugated culvert pipes, which is the second anti-corrosion. The second anti-corrosion should be Paint the mixture of asphalt and petroleum twice. From the outside, the inside and outside of the corrugated culvert pipe wall can be evenly painted into black pipes, but the asphalt must be dried before installation. The thickness of the asphalt coating on the outer wall of the corrugated culvert pipes is kept within 0.4mm-0.5mm.
