RSF Aluminium Stretcher Bars
Studio-engineered solutions for the care of art
Alongside our conservation services, RSF develops specialised products born from decades of hands-on restoration experience.
Designed for the realities of Southeast Asia’s climate — and tested in our own studio.
“ RSF’s aluminium stretcher bars address the problem at its source.”
Canvas tension is one of the most overlooked factors affecting a painting’s long-term condition. In tropical climates, traditional wooden stretchers absorb humidity, warp, and gradually lose tension — leading to canvas distortion, stress within the paint layers, and, over time, irreversible damage.
