Why Advanced Equipment

Steel where others use gypsum

Every ALPHA® panel is all-welded, all-steel — heavy 16 or 14 gauge faces robotically fusion-welded every 8 inches to the perimeter frame. That construction is why our panels reach 60 feet, carry limited warranties up to 20 years, and keep working decades after installation.

We're also the only manufacturer with true curved track and curved steel panels — and our Spacematic® automation sets up large exhibit halls automatically.

Service & Repair

We service every manufacturer's walls — not just ours

Repairs, retrofit, replacement, and refurbishment on all makes of operable partitions. If a wall in your building has stopped moving the way it should, our factory-trained crews can bring it back — often without replacing the system.

Common Questions

Answers before you ask

How much sound do operable partitions actually block?

Our ALPHA® all-steel panels carry laboratory sound ratings up to STC 54, with field-tested performance of NIC 42 under ASTM E 336 — and we guarantee field sound ratings on our large operable walls. Sound test reports are available in our document library.

How tall can an operable wall be?

We build one-piece panels up to 60 feet high and up to 60 inches wide — used in convention centers and exhibition halls where standard systems can't reach.

Can you repair a partition made by another manufacturer?

Yes. We service, retrofit, replace, and refurbish operable partitions from all manufacturers — see our Service & Repair page.
