STEEL SELECTION OF REGULAR GROUND FLAT STOCK (GFS)

To find the right Standard Ground Flat Steel for your project, you can use two methods:

Method 1: Initial or proactive GFS Steel Selection

For this method, it is necessary to determine the extent of the primary properties and dimensions the desired GFS steel must have.

Method 2: Reactive GFS Steel Selection

This method involves identifying the causes of failure or malfunction of the component and selecting the appropriate GFS steel grade based on the new required properties.
