As part of our art shipping services, we produce bespoke plywood crates and tri-wall cases to suit single or multi-piece shipments.
Although not recommended for high value, heavy, or very fragile items, the three-layered corrugated cardboard packaging (which is anchored at the sides by wooden struts) does provide a strong packing solution that is lighter than the plywood alternative.
Below is a video showing how we packaged a recent shipment of three framed canvases.
