Load capacity of sliding systems
What does the load capacity of sliding systems depend on?
The load capacity of a sliding system is an important parameter that determines the maximum door weight that a particular system can support. The load capacity is influenced by many factors that should be considered before purchase, since an incorrectly chosen system can damage the door or even the entire wall.
Before buying a sliding system, you should pay attention to the following:
- the structural strength of the wall or ceiling, which depends on the type of building material used (see tables below) and its quality. Different walls have different physical properties and limitations; for example, masonry walls are stronger than partition walls, which allows the installation of heavier doors. Building materials from reputable manufacturers that meet certain standards are also more durable and more suitable for installation.
- the strength of the components of the sliding system, which should be structurally designed so that they support the weight of the door and ensure safe, long-term operation of the entire system.
- the type of sliding system, which is designed for doors of a certain weight. Systems differ in load capacity and in the number of guide-rail fixing points, which additionally affects the installation options.
- the total weight of the door (check here), which depends on the material the door is made of. Materials such as wood, steel, mirror or glass have different masses, which directly affects the weight of the door and the load on the system.
If the weight of the door is not matched to the strength of the system and the wall structure, deformation of the guide rail, damage to the hangers, and damage to the wall or ceiling can occur.

CONCRETE WALL - Concrete walls must be solid and thicker than the required minimum anchoring depth of 3 cm.
MASONRY WALL - Masonry walls must be solid and thicker than the required minimum anchoring depth of 5 cm.
STEEL BEAM - The steel beams must be structural in nature with a minimum wall thickness of 0.6 cm.
FRAMED WOODEN WALL - Wooden frame walls must have at least 7.5 cm of solid wood fixed to the structural element.
PLASTERBOARD - For more information on installation on a plasterboard wall, see our blog post: "Installing sliding doors on a plasterboard wall".
AERATED CONCRETE - For more information on installation on an aerated concrete wall (gas concrete, Ytong blocks): Assembly set for aerated concrete walls.
