for bronze, 25-year for brass Frequently Asked Questions Q1: What is the difference between bronze and brass tape clamps? Bronze offers superior corrosion resistance, higher mechanical strength, and better performance in harsh environments, while brass provides good corrosion resistance at a more economical price point. Bronze is preferred for critical applications, while brass is suitable for standard applications. Q2: Can these clamps be used for lightning protection systems? Yes, our bronze and brass square tape clamps are specifically designed for lightning protection systems. They provide reliable connections for down conductors and earth termination networks, complying with IEC 62305 standards. Q3: What is the expected service life of your tape clamps? Our bronze tape clamps have a minimum service life expectancy of 30 years, while brass clamps offer 25 years when properly installed and maintained, with proven performance in various environmental conditions. Q4: Do you provide custom-designed clamps for specific applications? Yes, we specialize in custom clamp design and manufacturing. We can create clamps with specific tape sizes, special configurations, unique angles, and custom ratings to meet unique application requirements. Q5: What surface treatments do you offer for enhanced performance? We offer tin plating (5-8μm), passivation treatments, and special coatings for enhanced corrosion protection. For bare copper tape applications, we recommend tin-plated clamps to prevent bimetallic corrosion. Q6: What testing do you perform on finished clamps? We perform 100% dimensional inspection, mechanical strength testing, contact resistance testing, and sample destructive testing. Additionally, we conduct type tests including temperature rise, short circuit, corrosion resistance, and environmental testing.
