Most transit damage isn’t catastrophic. In many cases, it appears as a dented corner, a hairline stress fracture where the frame meets the canvas, or a chipped frame edge. These small but noticeable issues account for a large share of transit damage claims. The good news is that they are largely avoidable if you understand the simple structural reason behind them. Learning why artwork gets damaged during shipping can help you protect your artwork more effectively and ensure proper corner protection before transit.
Why Artwork Gets Damaged During Shipping: Frame Corners Take the Hit
To understand why artwork gets damaged during shipping, it helps to know how framed artwork behaves under stress. In physical terms, a framed painting acts as a rigid rectangle. When it is bumped, dropped, or leaned against a wall at an angle, the impact energy is distributed unevenly across the frame. Instead of spreading evenly, the force travels to the nearest corner, where it concentrates. The result may be compressed wood grain, cracked gilding or finish, or, in more severe cases, a frame that flexes or becomes distorted.
The Mechanism of Damage in Corners and Edges
The physics of artwork damage is not only about the corner itself. The real problem begins when the corner transfers the impact inward. While a slightly crushed frame corner often causes only cosmetic damage, a stronger impact can rack the frame out of square, placing shearing stress on the stretched canvas or even causing a fracture line in a wood panel. This type of damage often becomes visible on the painted surface days or even weeks after shipping, once the artwork returns to a stable environment and reaches equilibrium under normal room conditions.
How Can You Protect the Frame Better?
Fortunately, most of this damage is preventable, and professional art shippers understand the importance of protecting corners and edges. By working with experienced specialists, you can be confident that the most vulnerable parts of your framed artwork receive the attention they need. Packing professionals often apply dedicated corner protectors before wrapping and crating the artwork. These protectors create a buffer between the frame and the crate, absorbing impact instead of allowing it to transfer directly into the frame joints.
Standard professional practice includes installing corner protectors on all four corners, wrapping the artwork in acid-free tissue and bubble wrap, and placing it inside a snug-fitting box with 2–3 inches of clearance on every side. Heavily textured, oversized, and high-value paintings are often transported in slat or travel crates, which provide additional structural support while preventing packing materials from coming into direct contact with the painted surface.
