Xenith Steel
Steel replaced cast iron as the primary structural material because yield strength (235-690MPa per EN 10025) enables longer spans with less weight than cast iron's compressive-only capacity. Hot-rolled sections transfer loads through cross-sectional geometry: H beams (100x100-900x300mm, ASTM A36/A992) for columns with high moment capacity; I beams for moderate bending; U channels (50x37-400x104mm) for bracing and purlins; square hollow sections (10x10-1000x1000mm, ASTM A500/EN 10219) for axially loaded columns with equal buckling resistance in both axes; rectangular tubes (20x10-400x300mm) for beams with asymmetric loading; scaffolding pipe (48.3mm OD, EN39/BS1139/AS1163); and CHS (114-914mm OD). Surface: bare, painted, or hot-dip galvanized per ASTM A123. Supplied by Xenith Steel to construction EPCs, infrastructure contractors, and machinery OEMs in 80+ countries.

Frequently Asked Questions about Structural Steel Section

1. What structural steel sections does Xenith Steel manufacture?

Xenith Steel manufactures seven structural steel sections:

(1) H Beam: Hot rolled for building frames and bridges.

(2) I Beam: Hot rolled for load-bearing structures.

(3) U Beam (Channel): Hot rolled for purlins and framing.

(4) Square Steel Pipe: ERW and seamless for structural columns.

(5) Rectangular Steel Tube: ERW for beams and frames.

(6) Scaffolding Pipe: ERW for construction scaffolding.

(7) Structural Steel Pipe: CHS for architectural and structural applications.

2. What is the difference between H beam and I beam?

Two beam types differ in cross-section and load capacity:

(1) H Beam: Wider flanges with parallel inner and outer surfaces. Higher moment of inertia for better load distribution. Preferred for heavy-duty structures, bridges, and multi-story buildings.

(2) I Beam: Narrower flanges with tapered inner surfaces. Lighter weight for moderate loads. Used for mezzanines, platforms, and light structural frames.

3. What standards govern structural steel sections?

Xenith Steel follows five structural standards:

(1) ASTM A36: Carbon structural steel for general construction.

(2) ASTM A992: High-strength low-alloy steel for wide-flange shapes.

(3) EN 10025: European standard for hot-rolled structural steel.

(4) JIS G3101: Japanese standard for rolled steel for general structure.

(5) GB/T 706: Chinese standard for hot-rolled section steel.

4. What surface treatments are available for structural sections?

Xenith Steel offers six surface treatment options:

(1) Bare: As-rolled surface for indoor applications.

(2) Painted: Primer or full paint coating for corrosion protection.

(3) Light Oiled: Temporary protection during storage and transport.

(4) Galvanized: Hot-dip zinc coating for outdoor and marine environments.

(5) Zinc Coating: Electro-galvanized for moderate corrosion resistance.

(6) Primer: Anti-rust primer for field painting.

(7) Powder Coat: Electrostatic powder coating for architectural finishes.

5. What are the typical applications of structural steel sections?

Structural steel sections serve three main application areas:

(1) Industrial Construction: Factory buildings, warehouses, and industrial plants with H/I beam frames.

(2) Machinery Manufacturing: Equipment frames, racks, and container structures with square/rectangular tubes.

(3) Infrastructure: Bridges, towers, and multi-story buildings with wide-flange beams and CHS columns.

6. How does Xenith Steel package structural steel sections?

Xenith Steel offers three packaging options:

(1) Bundles with Strips: Steel sections bundled with steel straps for secure transport. Standard for beams and channels.

(2) Waterproof Paper Wrapped: Individual pieces wrapped for moisture protection during sea freight.

(3) Custom Packaging: Special crating, container loading, and marking per customer requirements for project-specific deliveries.
