Product Description
Manufactured from ASTM A992 carbon steel (with 50 ksi minimum yield strength), these beams feature an H-shaped cross-section that optimizes strength-to-weight ratio. Available in sizes from W4×13 to W36×300 (nominal depth × weight per foot), they form the primary framework in high-rise buildings, bridges, and industrial facilities.

High Strength-to-Weight Ratio: ASTM A992 grade offers yield strength of 345 MPa with 18% elongation, balancing load capacity and material efficiency.
Weldability: Low carbon equivalent (CE ≤ 0.45) minimizes cold cracking during welding, compatible with SMAW and GMAW processes.
Dimensional Consistency: Web and flange thickness tolerances within ±10% of nominal values (ASTM A6/A6M), ensuring uniform load distribution.
Fire Resistance: When coated with intumescent paint, provides 2-hour fire rating per ASTM E119, meeting building code requirements.
Commercial Buildings: Used as columns and girders in office towers, shopping centers, and hotels, spanning up to 60' between supports.
Industrial Facilities: Supports crane runways and mezzanines in manufacturing plants and warehouses.
Infrastructure: Forms bridge girders and overpass supports, withstanding dynamic vehicle loads.
Q: What is the maximum span for a W18×50 beam?
A: For uniformly distributed loads, maximum span is approximately 30' in unbraced conditions, increasing to 45' with lateral bracing.
Q: Can these beams be galvanized?
A: Yes, hot-dip galvanization adds 60-80μm zinc coating for outdoor applications, increasing weight by approximately 3-5%.
Q: How to calculate load capacity?
A: Refer to AISC Steel Construction Manual tables, considering span, support conditions, and load type (dead vs. live loads).
