Weiciste Corrosion-Proof Stay Rods with PP-R Tech|Solve Grounding Failures|30+ Year Lifespan
The Corrosion Kill Zone: Why 80% of Failures Happen Here
Field data from 37 countries proves: Over 80% of stay rod corrosion occurs at 20-40cm below grade - where soil electrolysis and oxygen differential peak. Traditional "full-length protection" wastes 70% of anti-corrosion resources.
Why Old Methods Fail
❌ Thickened Rods
200% cost increase for 30mm rods
Stress fractures at diameter transitions (15% breakage rate)
❌ Heavy Galvanizing
Zinc layer damaged during bending (ASTM A123 shows 60% efficacy loss)
Field repainting increases OPEX by 30%

Engineers' Verdict:
“Finally, a solution that attacks corrosion where it actually happens.”
