Galvatite high-strength steel

Galvatite high-strength steel allows the user to increase the strength of the finished component or reduce the steel thickness, or both. It also offers corrosion resistance and good forming properties.

Chemical composition

Galvatite high-strength steel meets the requirements of the cast analysis in the standard, as shown in table 51 on page 68.

Typical applications

· automotive components · cold-formed tubes · building frames · floor decking · racking and shelving · building components

Dimensions

The width and thickness limits are shown in table 52 on page 68. The minimum width for all products is 900mm. Widths below this may be available after consultation. Table 49: Standard: EN 10292 : 2000
