For separating cantilever arms. Prevents round materials from accidentally slipping off (storage regulation BGR 234 for round materials)
(from the French word "agrafe", meaning "staple") Hook clock used for fastening a brace or beam to the upright section. The hook transfers the loads onto the upright section, and also reinforces the rack.
Racks are reinforced either with diagonals (cross bracing) or with lingitudinal reinforcers/beams. Diagonal braces are often used on shelving units. On pallet racks, reinforcement is provided by the structural forces of the beams.
Reinforcing elements on the back of racks, consisting of diagonal bars. Diagonal reinforcing bars are used on shelving units and cantilever racks. This is a highly effective reinforcement method for supporting tensile forces.
Connecting element between two racks. Used when assembling pallet racks, where it ensures a uniform gap between the different racks.
Prevents pallets from being pushed through accidentally. Back stops are not intended to be used as a brake for the pallets in the same way as pallet stops.
Indicates the distance between the top surface of the warehouse floor (or shelf) to the top edge of the shelf above. This distance is also referred to as the buckling length. If the distance between two shelf levels in the rack is greater, this is crucial for the structural design of the rack. The shelf has a direct effect on the load capacity of a rack (→ bay load).
Shelf load refers to the loading on one shelf level or shelf between two frames. The load should be evenly distributed over the whole surface. The total of the shelf loads makes the bay load.
Total load capacity of a rack bay. A bay is the area between two frames. The sum of the shelf loads one above the other should not exceed the permitted bay load. Bay load is affected by compartment height.
These are used as reinforcements at specified positions on bolted racks. META brackets consist of an angled plate with integrated nuts, which makes assembly tremendously easier.
With electro-galvanisation, or zinc-coating, the parts to be coated are first cleaned with dilute acids, then dipped in a bath containing a salt solution of the coating metal (zinc). A current is then passed through the bath at low voltage. The electric current causes the chemical breakdown of the solution in the bath. The metal (zinc) separates out from the salt and is eposited in a thin layer on the part being coated.
Clinching is a pressure-joining process used at META for producing its QUICK frames. With this process, the upright parts are force-fitted to the linking bars/panel. In this way, the pre-assembled frames are made highly stable and robust. Unlike frames with bolted or riveted linking bars, there are no obstructions to the insertion of shelves at any point. This process is also being used increasingly in shelving production. It has significant environmental advantages over traditional welding.

On racks with tilted surfaces or roller strips, a picking tray is installed where the goods taken from the rack can be assembled.
Bracing beams are angle sections with one agraffe on right and left. They are used to reinforce boltless racks at defined intervals. The shelf is inserted in the folded angle of the beam. The standard reinforcement is the diagonal brace.
PP is resistant to almost all organic solvents and fats, as well as most acids and alkaline solutions. PP is odourless and gentle on the skin. It is suitable for applications in the foodstuffs and pharmaceutical sectors. It is physiologically harmless.
The plastic coating supplied by META is an epoxy-polyester based powder coating. It provides optimal abrasion resistance and the highest possible surface quality. Even when used for storing foods, the plastic coating does not give off any substances that might have an unpleasant taste or smell, or which could be harmful to health. The coating process used is completely harmless to the environment. There are no chemical waste products. The water required is fully treated in a cleaning process circuit. No waste water is discharged into the sewage system.
The raw material (steel) in the form of strips or sheets is cleaned by baking in a conveyor furnace, after which it is heat-treated, then passed through a bath of molten zinc. The desired amount of zinc coating is controlled and adjusted using the jet-stripping process. A crystalline structure forms as the zinc coat solidifies.
Locking pins have to be inserted to prevent accidental lifting of the beams in the pallet rack.
The adjusting screw on the cantilever arms (META MULTISTRONG L+M) is a type of lift lock. When the screw is tightened, it causes a plate with two teeth to be pressed into the upright section and against the cantilever arm itself. This raises the arm slightly. Round materials therefore roll toward the uprights and the arm cannot be lifted off accidentally.
Vertical load bearing element, which is given its geometry by cold forming. It is joined to the load-bearing frame by connecting elements such as linking bars or C-section braces. On boltless racks, it is the shelves and brackets which are the connecting elements. The uprights transfer the bay load to the warehouse's load-bearing floor.
See "Supports". Longitudinal or depth supports are inserted, according to the shelf type.
Supports are used for various reasons: With shelves, they can increase the load capacity. In general, they prevent sagging of the shelves. With stepped beams, they prevent hollowing out of the beams when under load. If chipboards are inserted, they prevent sagging and therefore breakage of the boards.
For safe storage of mesh box pallets. These have angled foot-plates, which make them difficult to store directly in pallet racks. The channel supports guide the foot plates of the mesh boxes, which can then be safely set down on the beams.
