B-Span Heavy Duty Shelving

[widgets_on_pages id=”Contact Us”]

A Wide Open Storage Alternative

Borroughs B-span® provides a heavy-duty storage solution with an easily accessible, widespan  design. B-span bridges the gap between clip-type shelving like Box Edge plus and full-scale pallet racking, and can accommodate hand-loaded items as well as pick lift loads (within the B-span load capacity ratings). Accessories such as back-to-back ties, wall ties and foot plates add strength and stability. The B-span keystone B-post design uses roll-formed posts as high as 19’ with keystone slots shared by beams to create a run. B-Span flush beams supporting either wire decking or corrugated flat steel meet practically any storage requirement. Flush bottom beams can also be used with Borroughs aisle-saver® to increase your systems’ capacity. Create full mat systems with B-span’s deck over beams.



Provides a solid connection between posts and beams. B-clips come standard with a passive safety spring clip.
