Stone benchtops can be extended up to 300mm with support solely from a substrate. If you need an overhang beyond this width, you will require additional support, which can take the form of brackets or a metal support frame (for overhangs between 300mm to 500mm), or legs, columns, or panels (for overhangs exceeding 500mm). When requesting a quotation, please consult with us, and we will gladly provide you with more information regarding the necessary support requirements.
