Explore our certified range of hot-rolled structural angles, C-channels, and wide-flange H-beams built for mechanical strength and dimensional precision.
From deep-sea solar installations to civil structural frameworks, discover how our custom profile shapes deliver stability under extreme mechanical loads.
We supply high-tolerance, thin-walled galvanized C-channels and equal-leg structural angles to construct corrosion-resistant ground-mount solar arrays, optimizing installation speeds and wind-uplift survival limits.
Our heavy-duty Q235B and SS400 hot-rolled steel angles are key components for high-voltage power transmission lines and structural lattice towers, displaying robust torsional rigidity under cyclic atmospheric loads.
ASTM standard W-beams (H-beams) act as horizontal girders and roof truss columns for massive automated warehouses. These structural units prevent plastic deformation while minimizing total building deadweight.
Structural steel configurations must withstand load-bearing demands. We focus on consistent chemical formulations, checking that sulfur and phosphorus limits are controlled to preserve toughness in low temperatures.
Our H-beams, equal/unequal angles, and C-channels comply with standards like GB/T 706, ASTM A36, EN 10025, and JIS G3101. This ensures compatibility with standard welding, punching, and hot-dip galvanization processes.
We apply high-performance zinc and zinc-aluminum-magnesium coatings, achieving typical coat weights of 80g/m² up to 600g/m² for projects in coastal and chemical environments.

Choosing the correct structural profile requires analyzing structural loads, shear forces, and bending moments. H-Beams feature parallel flange surfaces that provide substantial second moment of area along both axes, making them suitable for vertical columns and primary load-bearing horizontal beams in civil works.
C-Channels (Parallel Flange & Tapered Flange) offer structural support along a single axis. They are commonly used as secondary framing members, roof purlins, solar mounting rails, and horizontal wall supports, where torsional forces are minimal.
In outdoor environments, steel profiles face exposure to moisture and atmospheric chemicals. Our facilities apply hot-dip galvanization to form a metallurgically bonded zinc-iron alloy coating, protecting the base steel from oxidation.
We regulate the temperature of our molten zinc baths at 450°C to control coating thickness and uniformity. This treatment prevents rust, reduces maintenance requirements, and extends the service life of structures in marine, industrial, or agricultural projects.
Common questions regarding specifications, logistics, surface finishes, and global compliance standards.
We offer hot-dip galvanization with zinc coating thicknesses ranging from 45 microns (approx. 320 g/m²) to over 85 microns (approx. 610 g/m²), in compliance with ISO 1461, ASTM A123, and AS/NZS 4680 standards.
Yes. Our processing workshop handles CNC steel cutting, precision punching, and custom beveling. This allows structural profiles to be delivered ready for assembly, reducing on-site labor requirements.
Our production lines operate under ISO 9001 quality controls. We monitor section height, flange width, web thickness, and straightness to ensure compliance with standards like EN 10024 and ASTM A6.
Every shipment is accompanied by Mill Test Certificates (MTC) compliant with EN 10204 3.1, raw material heat number records, chemical testing analysis, mechanical test reports, and optional third-party inspection certifications from SGS or BV.
