Longspan Mezzanine Floors

Bowen Storage has the right longspan mezzanine floor solution for your warehouse or storage facility, let us tell you why…

Two-tier shelving systems can be constructed using the Sigma and Unirack shelving ranges, while it is also a cost-effective solution designed to suit the floor area in your new or existing warehouse.

These two-tier storage systems use standard modular shelving components to create raised storage areas that maximise warehouse volume and storage capacity, utilising all available ceiling height.

Sigma shelving is easily customisable for two-tier storage modules. Due to its lead-free galvanised finish, it is suitable for the storage of old archives such as books, documents, and manuals, etc.

Lighting and fire protection sprinkler systems can also be installed to comply with relevant building and fire safety standards.
