Data Center Structural Ceilings: Tate Grid+, Alustra, Duo & Strut

Tate structural ceiling grids suspend heavy data center infrastructure, such as cable trays, busway, containment and lighting, from one pre-designed ceiling system instead of custom-built strut. LG2 sells, supplies and installs Tate structural ceilings.

Data center infrastructure

Structural Ceilings in the data hall

A data hall hangs a lot from its ceiling: cable trays, busway, containment and lighting. A structural ceiling replaces custom-built, on-site support systems such as strut with a grid that is designed and specified in advance.

Tate's structural ceilings provide connection points to the building structure, a continuous slot for suspending equipment, and a grid for ceiling tiles, lights and return air grilles, so one system can carry both the infrastructure and the finished ceiling.

Tate offers aluminum and steel profiles with different load capacities and spans. Datasheets, spec documents, installation guides and Environmental Product Declarations (EPDs) are published for each.

Data center applications

  • Cable tray and busway

    Suspend cable trays, bus bars and other heavy accessories from a continuous slot.

  • Containment roof

    Support hot aisle containment and its ceiling panels from above.

  • Lighting and grilles

    Hang light fixtures and return air grilles from the same structural grid.

  • Finished ceiling

    Hold ceiling tiles, lights and return air grilles in the same grid.

Tate structural ceiling systems

Tate Grid+ LEC

The next evolution of Tate Grid, with a sleek profile and increased load capacity. Part of Tate's Lower Embodied Carbon (LEC) range, made with recycled aluminum.

  • Max safe working load of 475 lbs and max uniform load of 75 lbs/sf
  • 2x safety factor validated through third-party testing
  • Redesigned hold-down clips make tile installation easier
  • Notched main runners for accurate alignment

Tate Alustra

A heavy-duty aluminum ceiling grid with a strut-like profile: lightweight, strong and easy to transport and install.

  • Max safe working load up to 1,000 lbs with a spring nut connection at 4x4 hanger spacing
  • Two connection options for suspending equipment
  • Connects to the building structure anywhere along the mains, up to 8 ft apart
  • White or black painted aluminum; combines with the light structural grid for tiles and lights

Tate Strut

A galvanized steel strut profile whose welded flanges support tiles, light fixtures and return air grilles, so one system replaces two separate ceilings.

  • 12 gauge steel, hot-dipped galvanized, white or black powder coat
  • Continuous open top slot for connection to the building structure
  • Continuous open bottom slot for cable trays, bus bars and heavy accessories
  • Pre-drilled for light structural infill to keep a tile grid

Specifications as published by Tate. See the Tate structural ceilings pages and LG2 Tech Data for current documents.

FAQ

Frequently Asked Questions

Does LG2 install Tate structural ceilings?
Yes. LG2 sells, supplies and installs Tate structural ceilings, including Tate Grid+ LEC, Alustra, Duo, Grid and Strut.
What is a structural ceiling in a data center?
A structural ceiling is a pre-designed grid hung from the building structure that supports data center infrastructure such as cable trays, busway, containment and lighting, and can also hold the ceiling tiles. It replaces custom-built, on-site strut.
How much load can a Tate structural ceiling carry?
It depends on the system and layout. Tate publishes a max safe working load of 475 lbs and a max uniform load of 75 lbs/sf for Tate Grid+ LEC, and up to 1,000 lbs for Tate Alustra with a spring nut connection at 4x4 hanger spacing. Check the datasheet for your configuration.
Which Tate structural ceiling should I specify?
Tate Grid+ LEC and Tate Grid are aluminum grids; Tate Alustra is a heavy-duty aluminum strut-like grid; Tate Duo offers spans up to 8 ft with a two-layer threaded slot; Tate Strut is galvanized steel with welded flanges for tiles. LG2 sells, supplies and installs all of them and can compare them against your loads and layout.
Are EPDs available for Tate structural ceilings?
Yes. Tate publishes Environmental Product Declarations for Tate Grid+, Alustra, Duo, Grid and Strut, linked with each product on this page.
