W12x252 279 A36/A572GR50/A992 H Beam
ASTM A36 h beam steel structure is a low-carbon steel widely used in construction and general structural purposes, with good weldability and processing, but low strength.
ASTM A572/A572M Grade 50 h section steel beam is a high-strength low-alloy steel (HSLA), which is improved by adding trace elements (such as niobium and vanadium) and is suitable for structures that require higher strength.
ASTM A992/A992M h shaped beam is a modern high-strength low-alloy steel designed for wide wing steel, with higher yield strength and better toughness, and is the preferred material for North American building steel beams.
Characteristics of three materials in W12x252 and W12x279
A36 h shaped iron beam
Advantages: low cost, easy to weld and process, suitable for low-requirement scenarios.
Limitations: Low yield strength (36 ksi), may require larger sections in heavy-load structures, increasing weight and cost.
Applicable scenarios: small buildings, secondary components.
A572GR50 h-shaped steel beam
Advantages: Higher yield strength (50 ksi), stronger bearing capacity under the same cross-section, suitable for medium and high loads.
Limitations: Slightly higher cost than A36, slightly inferior weldability than A36.
Applicable scenarios: Bridges, industrial frames, medium and high-rise buildings.
A992 h-type beam
Advantages: Best comprehensive performance, high yield strength and controllable range (50-65 ksi), excellent seismic performance, widely used in modern buildings.
Limitations: Higher cost than A36 and A572GR50.
Applicable scenarios: Main beams of high-rise buildings, seismic design structures.
Features and applications of W12x252 W12x279 h type steel beam
W12x252 material h beam: Lightweight but with a larger cross section, suitable for scenarios that require high bending resistance but are weight-restricted, such as secondary beams of bridges or secondary load-bearing members in buildings.
W12x279 steel beam h: Heavier, with thicker flanges and webs, providing higher load-bearing capacity and shear resistance, suitable for primary beams or structures subject to extreme loads.
Both are in the "W12" series, with a height of approximately 12-14 inches, but the W12x279 h profile steel has stronger cross-sectional performance and is suitable for more demanding engineering needs.
