Product Introduction
S550GD high-strength galvalume steel coil is a premium structural grade product designed for heavy-load construction and steel framing systems. With 185g/m² Al-Zn alloy coating and high-strength steel base, it achieves an optimal balance of mechanical strength, corrosion resistance and formability.
As a leading galvalume manufacturer, CNB is among the first in China to achieve stable mass production of S550GD grade GL coils. This product is ideal for industrial plant structures, warehouse framing, floor support systems and large-span roofing systems, helping reduce steel consumption and lower project cost through higher strength-to-weight ratio.
