Trying to translate this from Russian to English, is it correct? If not, please correct my errors.

Мы хотим рассмотреть: 
кляммера под керамогранит толщиной 7-8мм и под керамогранит 11мм.

Отдельно кляймера для керамогранита толщиной 20 мм.

We are going to consider(review):

Cleat(clip) for ceramic granite with thickness of 7-8mm and for 11mm. 

Separately, cleat(clip) for ceramic granite with thickness of 20mm.

Hope that it is correct)


Not sure if this even comes close but I can't make sense of it, please help, thanks in advance.
