Tension Levellers

Tension Levelling Solutions

Bronx has decades of experience engineering Tension Levellers for ferrous and non-ferrous metals. Our advanced technology ensures superior strip flatness and improved mechanical properties across a wide variety of materials and line configurations.

Global Installations

Bronx has successfully delivered Tension Levelling solutions across multiple continents, including:

• Europe & UK: Norway, Poland, Spain, Switzerland, United Kingdom
• Africa: South Africa
• Asia: Bangladesh, China, India, Indonesia, Korea, Taiwan
• Americas: Canada

Performance Highlights

Our lines can achieve speeds up to 300 mpm (984.25 ft/min), process strip from 0.15 mm to 3 mm thick, and handle widths up to 1830 mm (72.04″). Bronx Tension Levellers offer unmatched flatness for high-quality surface-sensitive products, eliminating issues like luder lines and enhancing downstream formability.
