Hello,  We are interested in solar water heater's FRAME (BRACKET) of 1.5 mm. minimum thickness,  which has the ability to adjust its tilting angle on-site, from the horizontal axis, from about 10  to around 70 degrees, needed to support vacuum-tubes-collectors of 30-tubes of 58 x 1800 mm,  complete with reflectors that cover the entire collectors area, and all necessary accessories needed  to set up the frame on-site.  Regards,  Hayel Msherbash
