Choosing KLT Euro Containers in the 600x400 Grid
KLT Euro containers follow the 600x400 mm module and stack seamlessly onto Euro pallets, conveyors and racking. This guide explains the sizing logic, the difference between solid and perforated versions, and VDA compatibility for automated systems.
View KLT containersWhy is the 600x400 grid the standard?
The 600x400 mm base size is a divisor of the 1200x800 mm Euro pallet: exactly four KLT Euro containers of this size form one closed layer. Every other KLT format derives from this grid as a divisor or multiple, so container, pallet, racking and conveyor line up without gaps.
The common footprints are 600x400, 400x300 and 300x200 mm. Heights are stepped, typically 120, 147, 174, 213 and 280 mm. Shallow and deep containers therefore combine freely without leaving the grid.
Solid or perforated - which version fits?
Walls and floors come solid (smooth) or perforated (mesh). Solid protects small parts from falling out and from dirt, while perforated saves weight, lets swarf and liquid drain and is easy to clean.
- Solid wall and solid floor: for small parts, bulk goods and dust-sensitive items.
- Perforated wall with solid floor: lighter, well ventilated, still holds small parts safely.
- Fully perforated: minimum weight, ideal for wash processes and draining liquid.
- A reinforced floor and full-length grip ledges raise both load rating and stacking stability.
Stackability depends on the floor contour: a continuous stacking rim or floor profile centres the container placed on top and prevents sliding. Always check the manufacturer's stacking load, as it limits the maximum tower height in storage.
What does VDA compatibility mean for automation?
VDA 4500 defines the small load carriers (KLT) of the automotive industry and fixes dimensions, tolerances, floor design and labelling surfaces. VDA-compliant containers run through third-party systems without adaptation because footprint, floor and label pocket are standardised.
For automated small parts warehouses (AS/RS) and stacker cranes, tight dimensional tolerances, a defined floor and shape stability under load are what matter. If a container deviates from the grid or warps, the system stops. Also check for consistent colour and labelling for both visual and machine recognition.
Frequently asked questions
How many KLT containers fit on a Euro pallet?
Four 600x400 mm containers form one closed layer on a 1200x800 mm Euro pallet. Smaller footprints such as 400x300 or 300x200 mm give proportionally more containers per layer.
What is the difference between a Euro container and a VDA KLT?
Both use the 600x400 grid. The VDA KLT additionally meets the tight dimensional and floor tolerances of the VDA 4500 norm, so it runs through automotive automated systems without adaptation.
Should I choose solid or perforated walls?
Solid for small parts and dust-sensitive goods, perforated for less weight, good ventilation and draining liquid. For automatic conveyors the floor should always be flat and stable.
What load can KLT Euro containers carry?
Depending on size and version, around 20 to 50 kg is typical. Material thickness, a reinforced floor and the manufacturer's stated stacking load are the deciding factors.
