Two tier shelving systems can be constructed using the Sigma and Unirack shelving ranges. 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 and because of its lead free galvanised finish, is suitable for the storage of old archives such as books, documents, manuals etc. Lighting and fire protection sprinkler systems can be installed to comply with relevant building and fire safety standards.
