Galvanized Angle & Channel
Core Structural Steel Profiles · Superior Corrosion Resistance · 25+ Year Service Life
Overview
Focused on the R&D, production, and export of high-quality hot-dip galvanized angle steel and channel steel. Both product series — with excellent corrosion resistance, stable mechanical structure, and wide application compatibility — have become preferred profiles for construction, municipal, solar, and chemical industries. Factory direct, custom processing available, full export certifications provided.
Key Advantages
Galvanized Angle Steel — Versatile Support Profile
L-shaped cross-section: compact structure, uniform load distribution, easy installation. Hot-dip galvanizing per GB/T 13912 standard, average zinc layer ≥85μm, outdoor service life 25+ years — significantly reducing long-term maintenance costs.
Galvanized Channel Steel — Primary Load-Bearing Profile
Channel cross-section with high moment of inertia and outstanding bending resistance — effectively bearing longitudinal and lateral loads without deformation or fracture. Neutral salt-spray test 600+ hours, suitable for outdoor, humid, and industrial pollution environments.
Premium Material, Stable Mechanical Performance
High-strength Q235B/Q355B carbon steel: tensile strength ≥375MPa, yield strength ≥235MPa, elongation ≥26% — meeting all support and connection load requirements for long-term structural stability.
Flexible Customization, Wide Compatibility
Custom sizes and thicknesses per load requirements. Cut-to-length, drilling, bending, and other fabrication available — compatible with construction, bridges, chemical plants, ports, and PV bracket main beams.
