Product Introduction

Die-cast aluminum raised access flooring uses a one-piece panel with an orthotropic underside rib pattern that directs material where bending stiffness is needed. The corrosion-resistant, non-magnetic carrier panel is accurately manufactured for repeatable alignment on a 600 mm pedestal grid. Its open ribbed underside leaves space for service distribution and reduces panel weight compared with a solid slab. The top can remain coated aluminum or accept cleanroom PVC and conductive finishes, while each module can be removed to reach the plenum below.

Key Features

The one-piece aluminum casting avoids welded seams within the carrier panel and resists corrosion in controlled environments.

Orthotropic ribs provide high load capacity with controlled deflection while limiting unnecessary panel mass.

Non-magnetic aluminum is suitable around processes and instruments that restrict ferrous floor construction.

Conductive powder coating or resilient cleanroom covering can be bonded to the accurately machined top surface.

Customer Product Concerns

Cleanroom access flooring must combine frequent panel removal with corrosion resistance, tight fit and low particle-generating movement.

Paint damage exposes conventional steel panels to corrosion in humid service voids.The carrier panel is a corrosion-resistant aluminum casting rather than a painted carbon-steel shell.

Heavy solid panels slow maintenance and increase handling risk during access.The ribbed orthotropic design removes non-working material while retaining structural stiffness.

Ferrous floor components interfere with magnetically sensitive instruments.The principal panel body is non-magnetic aluminum, with understructure materials selected separately for the room.

Inconsistent panel dimensions create rocking edges and dirt-trapping height differences.Precision casting and machining provide repeatable corner geometry across the modular grid.
