Applications

Primary Framing

Main columns and rafters for portal frame buildings — warehouses, workshops, factories, and industrial facilities.

Multi-Story Structures

Columns and beams for steel-framed office buildings, commercial complexes, and mixed-use structures.

Heavy Industrial

Crane runway beams, equipment platforms, pipe racks, and mining infrastructure requiring high load capacity.

Bridges & Infrastructure

Bridge girders, support columns, and structural components for transportation and public infrastructure.

Custom Fabrication Options

Cutting & Drilling — Precision cutting to custom lengths, pre-drilled bolt holes per fabrication drawings
Welding & Assembly — Welded end plates, base plates, connection brackets, stiffener plates per design
Cambering & Curving — Cambered beams for long-span applications, curved sections for architectural features
Notching & Coping — End notching for beam-to-column connections, coping for flange interference
Surface Preparation — Shot blasting to SA2.5, primer coating (zinc-rich / red oxide), galvanizing
Marking & Labeling — Piece marking per erection drawings, barcode/RFID tagging for large projects

Packing & Container Loading

H beams are packed to maximize container space utilization and protect surfaces during transit:

Bundle Packing — Beams bundled in 3-5 ton bundles with steel strapping, wooden spacers to prevent surface damage
Container Loading — 40HQ container typically loads 25-28 tons of H beams; optimized stacking plan provided
End Protection — Plastic end caps to protect beam ends and prevent moisture ingress
Documentation — Packing list with piece marks, weights, dimensions; loading diagram for efficient unloading

Frequently Asked Questions

Q: What is the minimum order quantity for H beams?

A: For standard sizes, MOQ is 5 tons. For custom fabrication, MOQ is 10 tons or one 20ft container. Smaller quantities can be discussed for sample orders.

Q: Can you supply H beams with ASTM A572 Grade 50?

A: Yes, we supply ASTM A36, A572 Grade 50, and other international grades. Mill Test Certificate (EN 10204 3.1) is provided with each shipment.

Q: What is the typical lead time for H beam orders?

A: Standard sizes in stock: 7-15 days. Custom fabrication (cutting, drilling, welding): 15-25 days. Large projects (100+ tons): 25-40 days depending on complexity.

Q: Do you provide galvanized H beams?

A: Yes, hot-dip galvanizing is available per ASTM A123 / EN ISO 1461. Typical coating thickness: 85μm for sections over 6mm thickness. Galvanizing adds approximately 15-20% to material cost.

Q: Can H beams be spliced for longer spans?

A: Yes, for spans exceeding standard 12m length, beams can be spliced using bolted end-plate connections or welded splices. Splice locations are designed to avoid high-moment zones. We provide detailed splice design calculations.
