TOLERANCES

TECHNICAL SHEET

Heavy duty H-beam is a type of steel with a cross-sectional shape similar to the English letter "H". Due to its large size and load-bearing capacity, it is called steel heavy H beem.

It consists of upper and lower parallel flanges and a web plate perpendicular to the flanges. The wing edge is usually wide and thick, mainly bearing bending stress; The belly plate mainly bears shear stress, which enables H-beams to effectively distribute force throughout the entire section when subjected to external forces, thus possessing good mechanical properties.

Other fields: It also has important applications in marine engineering, power engineering, and other fields.

Features of Heavy H Section Steel

1.Excellent mechanical properties:

Strong bending resistance: The cross-sectional shape of heavy H beams enables them to effectively resist deformation when subjected to bending loads, resulting in better bending resistance than other steels under the same weight. This can reduce the amount of steel used and achieve lightweight design of the structure.

Good torsional performance: The flange and web of H-beam are perpendicular to each other, making force transmission more reasonable and adaptable to complex stress conditions.

Good stability: not easily deformed or unstable when subjected to lateral forces and bending moments.

Superior seismic performance: capable of effectively absorbing and dissipating seismic energy.

2.Good processing performance

Easy to cut: Heavy duty H-beams can be easily cut into the desired length and shape, with good cutting surface quality.

Good welding performance: Most heavy-duty H-beams have good weldability.

Easy to machine: Heavy duty H-beams have relatively low processing difficulty and can ensure machining accuracy.

3.Good economy

High material utilization rate: Due to the reasonable cross-sectional shape of heavy-duty H-beams, the mechanical properties of the steel can be fully utilized, reducing steel waste, improving material utilization rate, and reducing engineering costs.

Low installation cost: Heavy duty H-beams have larger component sizes, which can reduce the number of connection nodes, lower installation workload and difficulty during construction, thereby shortening the construction period and saving installation and time costs.
