What is A992 Galvanized?
A992 Galvanized is A992 supplied in the Galvanized condition — pick for outdoor, humid or unpainted-maintenance structures; base mechanicals are essentially unchanged but service temperature is limited by the zinc layer. A992 Galvanized has a yield strength of 375 MPa (54.4 ksi) and a tensile strength of 500 MPa (72.5 ksi) — weaker than 69% of steel grades. Elongation at break is 23% and the elastic modulus is 200 GPa (29 Msi). A992 Galvanized has a density of 7.85 g/cm³ (0.284 lb/in³), heavier than 56% of steel grades. It melts at 1,425°C (2,597 °F). HR is the default condition FabDigit quotes; Galvanized is available on request or by drawing note.

Working with A992 Galvanized
Is A992 easy to machine?
Machines like 1020/HSLA steel — free-cutting it is not; use sharp positive-rake carbide, moderate speeds and good chip control on drilled/coped connections.
Can A992 be welded?
Excellent: CE ≤0.47 makes it AWS D1.1 prequalified with E70XX/ER70S consumables, usually no preheat below ~40 mm thickness (preheat heavy jumbo shapes).
Can A992 be formed, bent or molded?
Hot-rolled shapes bend and cambers well hot or cold; keep cold bend radii ≥ 3t and avoid cold working across the k-area of W-shapes.
What surface finishes work on A992?
Requires protection — hot-dip galvanizing per A123, metallizing, or shop primer/epoxy; blast to SSPC-SP6 to remove mill scale before painting.

A992 Galvanized — frequently asked
What is A992 Galvanized used for?
A992 Galvanized is typically used for building I-beams and wide-flange columns, high-rise moment-frame framing, bridge stringers and bearing supports, heavy platform and mezzanine framing, crane runway support beams and braced-frame members and connection stubs. In short: heavy bridge structural.
What is the yield strength of A992 Galvanized?
A992 Galvanized has a typical yield strength of 375 MPa (54.4 ksi) and a tensile strength of 500 MPa (72.5 ksi) — weaker than 69% of steel grades. Strength varies by condition: see the 4 listed tempers.
Is A992 Galvanized easy to machine?
Reasonably — machinability is rated good (60/100, better than 83% of steel grades). Machines like 1020/HSLA steel — free-cutting it is not; use sharp positive-rake carbide, moderate speeds and good chip control on drilled/coped connections.
Can A992 Galvanized be welded?
Yes — weldability is rated good (55/100). Excellent: CE ≤0.47 makes it AWS D1.1 prequalified with E70XX/ER70S consumables, usually no preheat below ~40 mm thickness (preheat heavy jumbo shapes).
What surface finishes work on A992 Galvanized?
Requires protection — hot-dip galvanizing per A123, metallizing, or shop primer/epoxy; blast to SSPC-SP6 to remove mill scale before painting.
Can A992 Galvanized be formed, bent or molded?
Hot-rolled shapes bend and cambers well hot or cold; keep cold bend radii ≥ 3t and avoid cold working across the k-area of W-shapes.
What is the maximum service temperature of A992 Galvanized?
A992 Galvanized is rated for continuous use to about 200°C (392 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between A992-HR and A992-CR?
HR is the default condition — standard stock condition for A992 wide-flange shapes and structural bars — pick unless a coating or cold-formed section is required. CR: choose when tighter dimensional tolerance, a smooth scale-free surface or extra strength from cold work is needed; ductility and toughness drop. Yield strength is 380 MPa in HR versus 460 MPa in CR.
