In the chemical industry, equipment failure due to localized corrosion, pitting, or crevice corrosion is not just costly—it’s dangerous. Our Titanium Perforated Sheets are specifically engineered to replace stainless steel and nickel alloys in environments where chlorides, acids, and high temperatures would typically cause rapid degradation.
Chemical-Specific Advantages
1. Superior Passivation
Titanium naturally forms a stable, protective oxide film ($TiO_2$). Our sheets undergo a professional Acid Pickling & Passivation process to ensure this film is uniform, providing immediate resistance to oxidizing environments upon installation.
2. Optimal Flow Dynamics
Using high-precision CNC punching and laser cutting, we ensure that every hole is smooth and burr-free. This minimizes:
3. Specialty Alloys for Low pH
For environments involving reducing acids or low-pH conditions, we supply Grade 7 (Ti-Pd) perforated sheets. The addition of Palladium significantly improves crevice corrosion resistance in hot chloride solutions.

FAQ
Q: What is the most common grade for perforated sheets?
A: Grade 2 is the industry standard for most industrial applications due to its excellent balance of cold formability and corrosion resistance.
Q: Can you provide customized hole patterns?
A: Yes, we can manufacture staggered or straight patterns and custom "border-only" perforation based on your CAD drawings.
