IndiaWILLSTRONG® SSHP
Stainless Steel Honeycomb Panel
WILLSTRONG® Stainless Steel Honeycomb Panel (SSHP) combines corrosion-resistant stainless steel skins with an aluminum honeycomb core, providing exceptional rigidity and minimal weight.
Outperforming ACP in strength and stiffness, SSHP enables graceful curves, effective insulation, and large‑scale, durable, aesthetically appealing designs.
The hexagonal aluminum core, bonded between stainless steel and alloy backing, ensures outstanding flatness and impact resistance, eliminating oil-canning on expansive façades.
With A2 fire-rated safety and excellent dimensional stability, SSHP delivers reliable, long-lasting performance for modern architectural projects.

The ultra-lightweight stone honeycomb system perfectly merges the timeless elegance of natural stone with the precision contemporary facade.
This advanced combination creates a sophisticated dialogue between natural materiality and bold modern design.
Stainless steel honeycomb panels are an ideal solution for sculptures, roofs, ceilings, and facades.
With a corrosion-resistant surface and rigid honeycomb core, they provide exceptional flatness, durability, and a sleek modern look.
Its unique and classical finish is highly favoured for museums and libraries.
Just like Titanium-zinc, its unique texture provides great possibilities for architects.
