Custom extrusions are our speciality and we also stock a large range of standard profiles. section modulus of any section is the ratio of the moment of inertia to the distance of extreem fibre from the neutral axis. DESIGN OF Z-PURLINS: PART 1 Basics and cross section values according to EN 1993-1-3 Jörgen Robra a, Gerald Luza b a Zeman & Co GmbH, Vienna, Austria b austroSteel, Graz, Austria INTRODUCTION Z-purlins are possibly the most commonly used cold formed beams. 4 net tons per mile of track Bolt diameter 1”, 1-1/16” & 1-1/8” 26. Notation: I moment of inertia S. Corus is a subsidiary of Tata Steel, the world's sixth largest steel producer. 200 000 Newtons per square millimeter (N/mm2) I Moment of inertia (X & Y axis), inches4 or millimeters4. modulus of elasticity synonyms, modulus of elasticity pronunciation, modulus of elasticity translation, English dictionary definition of modulus of elasticity. 3 Light gauge. A beam that has a larger section modulus than another will be stronger and capable of supporting greater loads. S275 – a structural grade steel with a minimum yield strength of 275 N/mm² S355 – a structural grade steel with a minimum yield strength of 355 N/mm².
