Product Name: Hot-Rolled Structural I-Beam

Overview

An I-beam is a long steel bar with a cross-section shaped like the letter "I", consisting of a web and two flanges. This classic design gives it an exceptionally high section modulus and moment of inertia about its strong axis (parallel to the web), delivering unparalleled bending resistance. We supply I-beams compliant with major global standards like GB, ASTM, EN, and JIS, making them the primary choice for beams, columns, and truss systems.

Technical Specifications

Key Advantages

Superior Bending Efficiency

The "I" shape efficiently distributes material away from the neutral axis, achieving a much higher section modulus with less weight compared to a rectangular beam.

Excellent Structural Stability

The significant difference in moment of inertia between its two principal axes makes it ideally suited for carrying loads applied perpendicular to the web, offering great stability as a main beam.

Ease of Connection & Fabrication

The flat flange surfaces facilitate easy connection to other steel members (e.g., gusset plates) via bolting or welding.

Cost-Effectiveness

As a mature hot-rolled section, it is relatively low-cost to produce and readily available, offering a highly economical structural solution.

Typical Applications

Building Structures: Main and secondary beams in industrial plants and commercial buildings.

Bridge Engineering: Girders and support beams for medium and small-span bridges.

Mechanical Equipment: Chassis, frames, and guide rails for heavy machinery.

Vehicle Manufacturing: Truck frames and structural components for railway vehicles.
