The hot-dip galvanized treatment provides 10 years of corrosion resistance, the 18% perforation rate ensures sufficient drainage flow, the corrugated structure improves the overall compressive strength, which can bear 10 tons of load per linear meter, suitable for scenarios with high ground load such as industrial factories and freight terminals. The high-weight geotextile filter layer reduces sediment entering the pipeline to avoid blockage, the flanged coupling connection is tight to prevent water seepage and leakage, and the temperature resistance range covers extreme cold to high temperature environments for wider applicability.
The parameters include 5 meters per roll, 150 millimeters diameter, 0.8mm thick hot-dip galvanized steel plate, 10mm perforation hole diameter, 18% perforation rate, 300g/㎡ non-woven geotextile outer layer, 2.5MPa compressive strength, 10 tons load bearing per linear meter, temperature resistance range from -30℃ to 90℃, flanged coupling joint, and 3.2 kilograms per linear meter weight.
It is suitable for underground drainage of heavy industrial factories, drainage of freight yard stockpiles, drainage of airport freight area foundations, drainage of heavy highway service area subgrades and other scenarios. It can withstand heavy equipment rolling, resist corrosion of industrial wastewater, and effectively solve the problem of concealed drainage in high-flow and high-load scenarios.
