Revision No. Date Released Description
N/A 2/2007 First Edition. It is not intended that the dimensions and section properties in this First Edition be used for analysis or design purposes. Rather, it is intended that the format of this document, and the type and numerical values of information displayed herein be reviewed by the engineering community. Constructive criticism is sought from said community for consideration by the authors and Stainless Structurals LLC for the preparation of future editions.
Note that the data is functional only with shapes made by and/or certified by Stainless Structurals, LLC. They arenot to be used with uncertified shapes, as dimensions, mechanical properties and methods of manufacture vary.
Please access our web site at www.stainless-structurals.com for the most up-to-date information and range of available sections.New shapes and ancillary information are being added on a regular basis.

P r e f a c e
The Georgia Institute of Technology and Stainless Structurals, LLC intend to develop a guideline for the design of stainless steelstructures. The first phase of this effort is the development of a set of section properties for stainless steel rolled and laser-fused
shapes used for construction. This document contains section property tables for five shapes currently produced by StainlessStructurals LLC. It is anticipated that the number of such tables will be increased and documented through updates to this
document as new information becomes available.
Further, as subsequent phases of this effort are completed, this document also will be updated.

STAINLESS STRUCTURALS PRODUCTS
The dimensions and properties for Stainless Structurals Products used in construction are given in thispart of the guideline. For design purposes, each cross section is referenced with respect to a localCartesian coordinate system (x,y,z) where the local x-axis coincides with the centroidal longitudinalaxis of the member, while the local y- and z-axes coincide with the principal axes of the member cross-section as shown in Figure 1.
Five types of cross section shapes are covered in this document. These are: W-shapes, S-shapes,Channels or C-shapes, Structural Tees, and Angles. Properties of these shapes include cross sectionarea, shear areas, torsion constant, moments of inertia, product moments of inertia, section moduli,radii of gyration, warping constant, centroid and shear center locations, and principal axis orientation,and are computed in accordance with accepted engineering principles. All calculations are carried outby means of a computer program CIMTEC Calc developed by the authors. Reported section propertyvalues are rounded as follows:
a) to the nearest whole number when the computed value is 100 or greater,b) to the nearest one-tenth when the computed value is between 10 and 99,c) to the nearest one-hundredth when the computed value is between 1 and 9, andd) to the nearest ten-thousandth when the computed value is a number less than 1.
