ULTIMATE LOAD TABLES
INTRODUCTION
The following load tables have been prepared to assist the designer in specifying cold formed sections.
The tabulated values are only valid for use with the fixing details and recommendations proposed by the manufacturer.
This information has been prepared as a supplement to the main handbook for ease of reference in the design office.
