Agreed on the page-load squeaky squawk ...
Nice looking site; lots of content - more than I want to know about steel, but it would appear to be a content rich site ...
The taglines on the logo are not legible ...
Bibliografy? Should that be with a 'ph' for the 'f'? The file name is spelled with a 'ph' ....
Title tag need
SEO ... and the language of the description tag on the home page is stilted. Elsewhere metas are empty ... you will want some text navigation for
SEO ...
Perhaps you will resubmit the site when you have gotten further with
SEO ...
