In german, but I think it's the pics that are interesting...
TT Schmiedeeisen von Triebenbacher Schmiedeeisen, München, Germany
on the left side you can choose the style...
also you might try the google Image search with the the follwoing keywords
for german: "schmiedeeisen" AND "Geländer"
for french: "fer forgé" AND ("garde corps" OR "balustrade)
these give a lot of ideas...
Hope it helps
