Material number 1.0244: S280GD
1.0244 is the European material number (Werkstoffnummer, EN 10027-2) for S280GD, hot-dip coated structural steel, guaranteed 280 MPa yield — the purlin grade specified in EN 10346.
Reading 1.0244 digit by digit
An EN 10027-2 number has the form 1.XXYY. The leading 1 marks it as steel. The pair 02 is the steel group, and for this number that group is other structural steels. The final pair 44 is a sequential count inside that group and carries no meaning of its own — 1.0244 is simply the 44th entry registered there.
The group digits are the useful part. Reading 02 tells you what kind of steel you are looking at before you know anything else about it, and the 2 other numbers from group 02 held here are listed below.
