Steel Fabrication Source Factory For Truss Using H-Section Beam

‌

Wide-flange beams, commonly referred to as H-beams due to their distinctive "H"-shaped cross-section featuring parallel flanges and a central web, are the material of choice for contemporary truss frameworks. Produced as hot-rolled sections to standards such as ASTM A992 (Fy=345 MPa) and EN 10025 S355, they deliver:

‌Engineered Cross-Section Efficiency‌: Standard sizes vary from 100×100×6×8mm to 900×300×16×28mm (Height × Width × Web Thickness × Flange Thickness).
‌High Load Capacity‌: Section modulus (Sx) values can reach 6,380 cm³ for demanding structural applications.
‌Dimensional Stability‌: In compliance with AISC 360, flange width-to-thickness ratios are maintained under 0.56√(E/Fy).

System Design & Layout

Trusses utilizing H-beams are commonly engineered in three primary configurations:

‌Parallel Chord Truss Systems‌:

• Chords: Utilizing HEA 400-600 series sections.

• Web Elements: Employing Circular Hollow Sections (CHS) connected via K-type or Joint connections.

• Common Span Range: 24-60 meters, typically for industrial roofing.

‌Triangular Configuration Trusses‌:

• A hybrid design using HEB 300 series members for chords and T-sections for verticals.

• Joint intervals are optimally designed between 1/8 and 1/12 of the total span.

‌Curved Chord Arrangements‌:

• Fabricated from tapered H-sections (per EN 10210) with a minimum curvature radius of 15 meters.

• Primary Uses: Cantilevered stadium roofs and arched bridge structures.

Performance & Construction Benefits

‌Superior Bending Resistance‌: Flange thicknesses (16-40mm) enable moment resistance up to 4,500 kN·m.
‌Optimized Joint Design‌:

• Bolted connections use Grade 10.9 bolts (M24-M36) with end plates.

• Welded joints employ Complete Joint Penetration (CJP) details in seismic regions.

Enhanced Buildability‌:

• Erection is approximately 25% faster than with box-section truss systems.

• Achieves a roughly 40% reduction in self-weight compared to concrete structural solutions.

‌Fire Resistance Ratings‌:

• Unprotected structural endurance: 15-30 minutes (criteria: ambient temperature increase below 550°C).

• Application of intumescent coatings can increase fire resistance to 90-120 minutes.
