Symmetrical H-section with balanced flanges and web for high load capacity in both the horizontal and vertical directions.
The first choice for primary beams and columns in modern steel structures, enabling long-span designs without intermediate columns.
Main columns & beams for factories and pre-engineered buildings
High-rise structural frames, long-span roofs
Overpass girders, conveyor bridges
Seaport warehouses, logistics warehouses
/I-BEAM
I-beam
Load-bearing beams · 187 sizes
I-section with a narrower web than H, optimized for vertical bending and more economical for light to medium loads.
Suited to structures that need deep beams but not the two-way load capacity of H-beams.

Can't find it in the catalog? Enter the dimensions to calculate the weight yourself: angle, H/I, seamless pipe, steel plate, Larsen sheet pile.
Nominal density 7.85 g/cm³. Enter a unit price (VND/kg) to get the amount. Manufacturing tolerance ±3–5%.
W = (2B − t) × t × 0.00785 [kg/m]
A = 2B·tf + (H − 2tf)·tw → W = A × 0.00785 [kg/m]
* The formula excludes fillet radii — results are ~2-3% below Chinese/JIS weight tables (e.g. H350×350×12×19 ≈ 134 vs 137 kg/m in the tables).
A = H·tw + 2·(B − tw)·tf → W = A × 0.00785 [kg/m]
* U-channel: H = web depth, B = flange width, tw = web thickness, tf = flange thickness. Fillet radii not included.
W = (OD − t) × t × π × 0.00785 ≈ (OD − t) × t × 0.02466 [kg/m]
W = D × R × T × 7.85 × 10⁻⁶ [kg/plate]
Look up Larsen U-type sheet pile weights (SP-II → SP-VI). Select a type to get the standard kg/m per Chinese/JIS tables.
* SP = Steel Pile (Larsen U-type sheet pile). Size W×H×t. Quotes are usually based on theoretical weight; "−5%" is the tolerance on actual delivered scale weight.
