Description
Structural H-Beam & I-Beam Steel for Heavy Construction
As a premier supplier of Structural H-Beam and I-Beam Steel, Sino East delivers heavy-duty hot-rolled sections engineered for high-rise buildings, bridge girders, industrial platforms, and pre-engineered steel structures. Our beams are manufactured under strict ASTM A36, ASTM A992, and EN 10025 standards to guarantee consistent mechanical properties across every shipment.
1. H-Beam vs I-Beam: Structural Design Differences
The primary distinction between H-Beam and I-Beam sections lies in their flange geometry. H-Beams (also called Wide Flange Beams in North America) have parallel flange surfaces and a wider flange width relative to their web depth. This design offers superior lateral stiffness, making H-Beams the preferred choice for column applications and high-rise structural cores.
I-Beams (Tapered Flange Beams) have a narrower, tapered flange optimized for bending resistance in one direction. They are typically more cost-effective for horizontal beams in floor systems and bridge girders.

3. Quality Control & Mill Testing
Every batch of structural beams dispatched from our Tianjin facility is backed by full metallurgical documentation. Our QC protocol includes:
- EN 10204 3.1 Mill Test Certificate — Chemical composition (C, Mn, Si, P, S) and mechanical properties (Yield Strength, Tensile Strength, Elongation) verified for every heat number.
- 100% Ultrasonic Testing (UT) — Internal flaw detection to ASTM A578/A578M for critical structural applications.
- Dimensional Verification — Laser measurement of camber, sweep, and cross-sectional tolerances per ASTM A6.
4. Container Loading & Export Logistics
Sino East optimizes every container to minimize your landed cost per ton:
- 20GP Container: Maximum loading 25-27 tons for 6m beams.
- 40HC Container: Accommodates 11.8m beams, up to 26 tons.
- Surface Protection: Red-oxide primer or anti-rust oil to prevent maritime salt-spray corrosion during sea transit.
- Port of Loading: Xingang Port, Tianjin — daily vessel schedules to major global hubs.
5. B2B Wholesale FAQ
What is the MOQ for H-Beam orders?
Our standard MOQ is 25 tons per size specification. For mixed-size container loads, we can combine H-Beams, I-Beams, and Channels in a single shipment.
Can you provide welded H-Beams or only hot-rolled?
We primarily supply hot-rolled structural sections which offer superior grain structure and load-bearing integrity. Fabricated/welded H-Beams (built-up sections) can be arranged for non-standard flange-to-web ratios beyond typical rolling mill capabilities.
Do you supply with drilling and fabrication services?
Yes, we provide end-plate welding, bolt-hole drilling, stiffener fabrication, and protective painting to your engineering drawings. Send your fabrication checklist with your RFQ.
