Graphics that take flight

Durable Printing for Large-Scale
Exterior Applications

Developed by the same team of experts that perfected FOLIA™,  the ALTO™ process has been refined since 2007 into a uniquely durable, eco-responsible and vibrant aluminum surface material for large-scale exterior applications.

We use a proprietary dye-sublimation process to infuse powder-coated aluminum with high-resolution digital images for long-lasting, vibrantly colored, and easy to install panels as specialty printers. The ALTO product is ideal for large-scale public art, mural and building skin projects, as well as multi-site civic projects. 


Thanks to the quality of inks and durability of our powder coats, ALTO™ Aluminum panels are trusted by designers, architects, fabricators, and organizations around the world.

MacLaren Youth Correctional Facility

Salem, OR


2020 SEGD Merit Award in Placemaking & Identity

Six original pieces bring remarkable color and an inspiring message to the exterior walls of this youth correctional facility.


Painted in the artist’s studio, then fused into powder-coated ALTO™, the murals become a part of the architecture.


The material was chosen for its durability and resistance to the highly-humid environment of Oregon.

ALTO Aluminum Exterior Mural with durable and resistant to high-humid environments


Anonymous Somebody Murals
Runnymede TTC Station, Bloor Village West, Toronto, ON

Based on sketches the artist made during his travels on the Toronto subway, Anonymous Somebody tells the stories of the Bloor West Village in a series of brightly colored murals. Celebrating the colorful individuals we meet on our daily commutes, these murals celebrate the past, present and future of a diverse community.

The artist's painting were sublimated onto ALTO™ aluminum, which will resist environmental damage in this high-traffic station where temperature changes and vibrations are the norm.

PGAV Destinations

Since this project would be within reach of tens of thousands of fans every home game, the graphic panels needed to be extremely durable and long-lasting. The panels also needed to reproduce the inductee portraits, text, and color in a clear, high-quality way. ALTO was the ideal choice for these reasons.

Louise Griffin, Artist

When creating public art, especially an exterior piece, there are a lot of additional requirements around durability, fading and manufacturer’s warranty. Not only does the Alto product hold up to the harshest weather conditions but SH provides one of the best warranties in the profession AND you do not have to sacrifice beauty or design. I love the Alto product. Unlike solid powder coating, Alto can provide a completely custom design filled with a rainbow of bright and intense colors. You create the artwork, submit your high resolution image and the finished product is as bright and beautiful as your digital artwork.

We have finished the inspection and post-painted assembly on the 4 projects… all looked great.  At the end of the 4 projects, we had over 2000 image panels with no rejects! Nice job and thanks for expediting this order ahead of the original lead-time.
