Irreplaceable Core Advantage

✅ Extreme Corrosion Resistance Lifetime

The 316L material boasts a lifespan of ≥30 years in a 5% NaCl salt spray environment—more than five times longer than galvanized cable trays—and requires no maintenance throughout its lifetime.

✅ Compatible with Clean and Sterile Environments

Mirror-polished (Ra ≤ 0.8 μm) to inhibit microbial adhesion, certified cleanroom compliant with FDA/ISO 14644 standards, ideal for pharmaceutical and food production lines.

✅ Inherently Safe Protection

No risk of coating flaking, eliminating zinc contamination; electrical conductivity ≥ 1.45 × 10⁶ S/m, providing natural antistatic and electromagnetic shielding.

✅ Ultra-wide temperature range stability

Linear thermal expansion coefficient ≤ 17.3 × 10⁻⁶/°C, remains crack-free at -60°C, and maintains its shape under high temperatures in chemical reaction zones.
