We are interested for big quantities of thermal break aluminum profiles for casement doors and windows, powder painted. There is a big European program for the replacement of outside doors and windows of old buildings by new ensuring good heat isolation. The profiles must be suitable to fit tilt and turn hardware systems of well known brands (ROTO, SIEGENIA, etc). We need prices per Kg and your e-catalogues with drawings of the profiles and the accessories. It should be appreciated if you could suggest us some Chinese hardware manufacturer with products similar to the European brands and same level of quality.
