Clean room stainless steel panels

The nobility and quality of AISI 304 and AISI 316 stainless steel, thickness 10/10, allow the use of this kind of panels where very high environmental standards are required.

The PMI panel is the ideal solution for critical processing areas where production must be carried out with no microbiological or particulate contamination to product.

The metal sheets are mounted on an extruded aluminium internal frame. The total thickness of the panel is 60 mm and the core infill can be polystyrene (PMI-H), aluminium honeycomb (PMI-H) or rockwool (PMI-R).

The panel is available in the standard dimensions 3076x1226x60 mm or can be produced according to the Client’s requirements.

The panel is designed to host preparations for electrical conduits or boxes for electrical devices, aeration grills and vision panels.

The whole of the panel components give an exceptional mechanical resistance, total monolithicity of the module and significant thermo acoustic insulation.

The patented fixing system with the CH 60 locking keys allows the removal of a single panel without affecting the others, by simply removing the silicon between the junctions and then sliding the locking key along the groove. Installation and maintenance times will thus noticeably be shortened.
