Particle Board Longspan Shelving Add-on Bay

When you need to extend your storage footprint, you don't need to buy another freestanding unit. The Industrial Longspan Add-on Bay is designed to lock directly into your existing setup, sharing an upright frame with your Starter Bay to create a continuous, heavy-duty storage run.

Step 2 of Your Modular Storage Build

Scaling your storage shouldn’t be complicated or overly expensive. Designed as Step 2 of our modular longspan system, this Add-On Bay hooks straight into your current layout. High-density particle board timber decks drop neatly into step-down beams, sitting completely flush so you can slide archive boxes, storage tubs, tools, and heavy inventory along the entire row without snagging.

All horizontal beams feature safety locking pins to ensure they remain securely seated, even under heavy upward impact during daily hand-loading operations.

Complete 3-Shelf Tier Configuration

Each Starter Bay comes equipped with three complete shelf levels out of the box. Every level includes two precision step beams, safety locking pins, and a heavy-duty particle board insert. Shelf levels adjust up or down in 50 mm increments, allowing you to tailor spacing for tall cartons, tool chests, or compact parts tubs. Need higher picking density? Additional tier levels can be purchased separately at any time.

Important Notice

An Add-On Bay cannot stand alone. It is supplied with 1 x Heavy-Duty End Frame and is designed to connect directly onto an existing Longspan Starter Bay or another Add-On Bay.

What’s Included in This Package:

  • 1 x Heavy-Duty Pre-Assembled End Frame: High-grade, welded steel upright in industrial gunmetal grey powder coat.
  • Heavy-Duty Step Beams: Recessed step-down profile designed to hold chipboard inserts flush.
  • High-Density Particle Board Decks: Smooth, heavy-duty timber shelf boards cut to size.
  • Safety Locking Pins: Steel safety clips to lock beams securely in place and prevent accidental dislodgement during hand-loading or forklift operations.
