Product Overview
Huaxia-Steel supplies hot-rolled carbon steel I-beams (also known as universal beams, IPN/IPE sections) directly from the rolling mill to international B2B buyers. The I-shaped profile — two parallel flanges connected by a central web — is the most efficient steel shape for carrying bending loads, which is why I-beams remain the backbone of buildings, bridges, crane runways, racking systems, and equipment frames worldwide.
We stock and roll I-beams to ASTM A6/A36, JIS G3192, and EN 10365 (IPE/IPN) dimensions, in grades from S235JR/Q235B to S355JR/Q345B, with lengths cut to order and full EN 10204 3.1 mill certification on every shipment.

Dimensional Tolerances
| Parameter | Tolerance (typical, per GB/T 706 / EN 10365) |
|---|---|
| Height (H) ≤400 mm | ±2.0 to ±3.0 mm |
| Flange width (B) ≤150 mm | ±2.0 to ±3.0 mm |
| Web thickness | ±0.5 to ±1.0 mm (thickness band dependent) |
| Straightness | ≤2 mm per meter; ≤0.15% of total length |
| Flange slope | Within standard series geometry (typically 1:6 on IPN-style rolls) |
| Length tolerance | +50 / 0 mm for cut lengths; exact cutting (±3 mm) on request |
