Glass on steel: why we never clamp the plate

Reclaimed steel moves with temperature and is never truly flat. A rigid clamp turns both facts into a crack. The answer is four points and an interface that gives.

Glass on steel: why we never clamp the plate
Concept render — production units in progress

01Four points, not a frame

A continuous frame demands a plane the steel does not have. Four discrete stainless carriers let us shim each contact to the real surface, so the glass rests on a plane we define rather than one we hope for.

02The interface has to give

Between steel and glass sits a bonded elastomer pad — thin, invisible from standing height, and stiff enough to transmit load without transmitting the point stress that starts an edge fracture.

The glass never touches the steel. That is the whole rule.

03Specification, not preference

Tempered laminated glass throughout, 15 to 19 mm depending on span, polished edges on every exposed side. On tables over two metres the plate is set on site, because the risk is never the transport — it is the handling at the door.
