Aluminized Silicon Steel Coil (AS) – Custom Slit Narrow Grade
Product Overview
Precision-slit narrow aluminized silicon steel (AS) is manufactured from wide master coils on high-precision slitting lines, providing customized width specifications for tube manufacturing, small profile forming, hardware stamping and other narrow-material applications. This AS100 DX52D grade delivers consistent forming performance and uniform corrosion protection for high-volume secondary fabrication.
Why Choose CNB Custom Slit AS Steel?
Our in-house high-precision slitting lines deliver tight width tolerances and clean, burr-free cut edges, eliminating secondary deburring operations for customers. We can slit AS coils to any width from 50mm to 600mm, with full control of coil winding tension, edge quality and recoiling tightness. The DX52D forming grade ensures excellent performance in roll forming, bending and tube welding processes, with no coating peeling or edge damage.
