Cleanroom Wall and Ceiling Systems

Hollow MgO Cleanroom Sandwich Panel

A cleanroom sandwich panel built around a profiled hollow magnesium oxide core, reducing solid material mass while retaining firm inorganic webs that support flat steel facings and convenient internal service routing.

Product Introduction

Hollow MgO Cleanroom Panels use molded magnesium oxide profiles rather than a fully solid core. Internal ribs support the outer metal skins, while continuous cavities reduce weight and can accommodate carefully routed low-voltage services. The hard inorganic webs create useful bearing zones around the panel perimeter and at prepared openings. Steel facings close the core from the controlled room, and framed edges protect the hollow geometry during cutting and installation. This construction is particularly useful for ceiling modules and service-integrated partitions.

Key Features

Hollow channels reduce material mass compared with a solid magnesium core.

Internal MgO ribs transfer surface pressure between the two metal faces.

Selected cavities can carry pre-planned conduits without exposing services in the clean area.

Four-sided framing closes the hollow ends and protects the core profile.

Factory-prepared openings preserve rib continuity around lights, outlets and inspection points.

Customer Product Concerns

The main concerns are unsupported cut-outs, concealed-service access, edge damage and local point loading.

Random site cutting can sever internal ribs and weaken the panel around an opening.Factory-planned cut-outs retain supporting webs and add perimeter reinforcement where needed.

Loose cables inside an inaccessible cavity are difficult to inspect later.Defined conduit routes and labeled access points keep concealed services orderly and traceable.

Open hollow ends can trap debris or expose the internal structure.Closed edge frames seal every perimeter and provide clean interfaces to adjacent modules.

Concentrated ceiling loads can fall between the core ribs.Local inserts transfer fixtures to reinforced zones instead of relying on an unsupported cavity.

Typical Applications

Service-integrated cleanroom partitionsLighting and utility ceiling modulesLaboratory wall systemsElectronics manufacturing roomsMedical clean corridors
