Q355 H-Beam Product Specification Table
Short Description (for homepage/card)
Q355 H‑Beam is a high‑performance structural steel profile with optimized section geometry, excellent load capacity, and cost‑effective performance. Widely used in buildings, bridges, steel structures, machinery, and engineering projects.
Full Description (for product page)
Q355 H‑Beam is a hot‑rolled structural steel section with an H‑shaped cross‑section, featuring parallel flanges and uniform thickness distribution. Made from Q355 high‑strength low‑alloy steel (yield strength ≥355MPa), it delivers superior bending resistance, stable mechanical properties, and reliable weldability.
Compared with conventional I‑beams, Q355 H‑Beam offers a more reasonable strength‑to‑weight ratio, higher section modulus, and more uniform stress distribution. It helps reduce structural weight, save material costs, and simplify on‑site installation.
