Artefex ACM panels, 3mm thick for durability, with 6mm Gridpanel for larger sizes, offering stable support for artwork.

We cut Artefex ACM panels to standard sizes but we also cut custom panels in any shape or size you don’t see above.

Artefex panel inspection and stamping process, ensuring quality and longevity for artists and collectors' artwork.

We use 3mm thick ACM panels to provide the most durable, rigid, and long-lasting support for your art. ACM panels do not react to relative humidity and other environmental changes, providing a very stable support for artwork. For larger sizes up to 5ft by 10ft we use a 6mm thick Gridpanel.

Finally we inspect and stamp every panel before sending it to you. This stamp represents an insurance policy not just for artists but for collectors. Your artwork is safe on an Artefex panel for generations.
