Product Overview
BELNADE supplies high-precision narrow strips and continuous coils engineered specifically for component manufacturing, continuous stamping, and automated electronic fabrication lines. Processed to exacting narrow tolerances, our metal strips exhibit stable mechanical behavior, clean edge conditions, and excellent formability, making them the preferred raw material for delicate industrial hardware, flexible mechanical elements, and high-reliability electrical components.
Standard Dimensions & Size Matrix
Manufacturing Process & Technical Conditions
Our precision strip products are created via specialized cold-rolling and high-speed slitting technology. Precision Slitting: Raw mother coils pass through advanced slitting lines equipped with micro-adjustable tungsten carbide tooling to yield clean, burr-free edges (Square edges or rounded edge options available). Bright Annealing: Controlled bright annealing under a protective hydrogen/nitrogen atmosphere eliminates internal residual stress and delivers the exact tempers required—ranging from soft annealed, 1/4 hard, 1/2 hard, to full spring hard conditions.
Available Alloy Grades & International Standards
Industrial Applications
Flexible Elements: Metallic expansion joint bellows, flexible instrument hoses, and hydraulic compensator diaphragms. Electronics & Energy: Electronic hardware contact springs, sensor diaphragms, micro-switches, and lithium-ion battery connection tabs. Aerospace Hardware: High-temperature seal elements, miniature lock gaskets, and precision-stamped fastening brackets. Instrumentation: Capillary protection tubing lines and compact heat exchanger louvered fin components.
Quality Control and Testing Regime
Inline Monitoring: Strip production is monitored continuously via optical gauge and thickness scanning systems to ensure cross-sectional uniformity. Destructive & Physical Testing: Finished coils undergo rigorous sample testing for tensile strength, elongation limits, surface finish roughness, and edge burr elimination. Third-Party Inspection: Full cooperation provided for third-party verification and client-nominated agency inspections (such as SGS or BV) prior to export dispatch. Certification: Complete EN 10204 3.1 Mill Test Certificates are provided with every batch to verify exact chemical melt composition and mechanical properties.
Packaging and Export Logistics
Strips are carefully wound and interleaved with moisture-barrier paper or plastic protective films to prevent scuffing. Coils are sealed in moisture-proof vacuum wrapping, vertically or horizontally positioned, and packed inside reinforced, waterproof-lined wooden boxes engineered to withstand rigorous ocean and air shipping conditions.
