S250GD equivalent grades: ASTM, EN, JIS, GB, DIN
S250GD is hot-dip coated structural steel, guaranteed 250 MPa yield specified in EN 10346. Every grade in the database that can stand in for it is listed below, drawn from 5 standard systems, each with the reason it does or does not match exactly. The full S250GD data sheet carries the composition and mechanical tables.

For S250GD the exact matches are S250GD+Z, IS 277 Grade 250, and material bought as one is accepted as the other without deviation. SS Grade 37 (A653), S280GD, SGC340 differ by one requirement, which is a line on the order rather than a redesign. S350GD, DX51D, S235JR and 1 more serve in the same applications, but the composition differs enough that the engineer signs it off, not the buyer. Across systems that is 1 in GB/T (China), 1 in IS (India), 1 in ASTM / ASME, 5 in EN (European), 1 in JIS (Japan).
Cross-reference table
| Grade | System | Match | Why / differences |
|---|---|---|---|
| S250GD+Z | GB/T (China) | Identical | GB/T 2518 adopts the EN designation (also listed as 250 by yield). |
| IS 277 Grade 250 | IS (India) | Identical | Indian galvanized sheet with 250 MPa yield. |
| SS Grade 37 (A653) | ASTM / ASME | Near | ASTM A653 Structural Steel Grade 37 [255]: 255 MPa yield, 360 MPa tensile — the closest US structural galvanized grade; SS Grade 33 [230] sits just below. |
| S280GD | EN (European) | Near | Next class up (280 MPa); the common purlin grade when S250GD is not stocked. |
| SGC340 | JIS (Japan) | Near | JIS G3302 SGC340: yield ≥ 245 MPa, tensile ≥ 340 MPa, A ≥ 20 % — Japanese structural galvanized. |
| S350GD | EN (European) | Functional | Same chemistry family, 350 MPa yield; used where span tables require it. |
| DX51D | EN (European) | Functional | Same substrate family without a guaranteed yield — for bending and profiling that is not load-bearing. |
| S235JR | EN (European) | Functional | Uncoated hot-rolled structural steel of similar strength for members that will be post-galvanized. |
| DX52D | EN (European) | Functional | Same standard and coatings but a structural grade with a 250 MPa minimum yield — specified when the sheet carries load rather than being formed. |
Identical, near and functional are defined once on the grade index; the reason column below says which limit differs in each case.
