Bare steel (black)

Hot-rolled scale surface, lowest cost

Indoor structures, painting after welding

Hot-dip galvanized

Zinc coating ≥40μm, excellent corrosion resistance

Outdoor, coastal, high-corrosion environments

Shot-blast + anti-rust paint

Clean surface, good paint adhesion

Steel structures requiring coating

Powder / plastic coating

Custom colours, decorative and anti-corrosive

Decorative or aesthetic requirements

High Load Capacity

Large section modulus, superior bending and compression resistance compared to I-beams, saves 10-15% steel

Excellent Structural Stability

Wide parallel flanges for easy connections; good overall rigidity

Complete Size Range

HW, HM, HN series covering heights from 100 to 900 mm, ample stock

Precise Dimensions

Hot-rolled to tight tolerances, clean-cut ends

Easy Fabrication

Easy to cut, drill, weld – suitable for shop prefabrication and site assembly

Custom Lengths

Cut-to-length service (6m, 9m, 12m, etc.) reduces on-site waste

Multiple Anti-corrosion Options

Bare, galvanized, coated – adaptable to various environments

Export-Ready Packaging

Strong bundling, waterproof and rust-proof for ocean freight

Building Steel Structures

Columns and beams for high-rise buildings, residential blocks, commercial complexes

Industrial Plants

Municipal Facilities

Subway stations, viaducts, pedestrian overpasses

Machinery Manufacturing

Equipment bases, heavy machinery frames, press bodies

Power Towers

Large transmission towers, telecommunication masts

Shipbuilding & Offshore

Hull frames, offshore platform structures

Bundled Packing

Bundled by size with steel straps/wire, each bundle approx. 3-5 tons

Timber Supports

Wooden blocks underneath for forklift handling and end protection

Waterproof & Rust-proof

Anti-rust oil for bare steel, wrapped with waterproof fabric

Custom Marking

Labels or stenciled markings as per customer request

Loading Port
