Longspan Shelving

Apex Type Longspan Shelving.

Longspan shelving & racking is designed to be easy to assemble, have good stability, yet remain low cost. This is driven by the modular configuration, made up of frames, beams and chipboard decking.


Each frame (upright) is composed of two metal, perforated uprights. The uprights are joined together with diagonal bracing to provide stability.

The frame uprights are perforated to allow boltless attachment of the beams – a characteristic that gives rise to the often used generic term of “Boltless Shelving”. The perforations are tapered in order to positively locate the cross-beams, guaranteeing a rigid shelving unit when built. The perforations are adjustable every 50mm to give plenty of flexibility when it comes to positioning shelves.


The beams fit between the frames and support each chipboard deck (shelf).


Once the beams are in place, shelves are laid between them. Shelves are generally made of chipboard.


You will often hear people referring to “levels” when talking about longspan shelving systems. This term simply means the combination of two beams and a shelf.


A Starter Bay has two end-frames and normally two or more levels. This is the item needed if you want a standalone longspan shelving unit. To extent the starter bay into a run of bays, add on bays are added.

Add-on (extension bays) come with a number of levels but only one frame. This is used in a run of shelves as one end of the beam fits in the frame of the bay next to it.

This configuration, making use of common frames, allows you to keep costs down by reducing the number of frames required in a run. For example, a continuous run of four bays needs only five frames, rather than the eight frames required by four single bays.
