DOLUFLEX® panel can be easily worked with standard woodworking equipment or by CNC machining centers numerically controlled with standard tools for cutting and drilling. MATERI A L S AND FINISHES Galvanized steel IDOLUFLEX® panel can be manufactured using galvanized steel sheets of 0.4 mm for both the corrugated core and the external sheets.

Post-painting DOLUFLEX® panel can be liquid post-painted. As standard, all coating techniques that do not exceed the threshold of 80 °C are suitable.

Pre-painting - Prefinished surfaces DOLUFLEX® panel can be produced directly using industrially pre-painted aluminum sheets, powder or liquid, or pre-finished with multiple opportunities to decorum (such as wood, stone and many others). These materials are produced by specialized suppliers. In this case the surface is protected with a peel-able PVC Coverings DOLUFLEX® panel can be covered with various materials. The main coverings used are: ❯ HPL plastic laminates ❯ real wood veneer ❯ natural or synthetic leather ❯ upholstery ❯ tissues ❯ 3M or similar adhesive films ❯ ceramic tile ❯ marble, stone and granite ❯ porcelain tile, Kerlite® ❯ glass ❯ Corian, Pral, Hi-macs and similar solid surface film which prevents damages during the production, from ❯ fiberglass the processing to the assembly on site. The great advantage is therefore, after the appropriate processing, a panel that requires no further finishing For many years now, DOLUFLEX® panel has been used processes. in various productive industries; the main are: shipbuilding Anodized • furnishings This finish is obtained by producing DOLUFLEX® panel • railways from anodized aluminum sheets; the treatment’s standard • thickness is 5 microns, but thicker anodizing alternatives • building are available upon request. • design

Also in this case the surface is protected with a peel-able PVC film which prevents damage during the production, from the processing to the assembly on site.

The most used anodizing color is natural silver but, upon request, other colors are available.

Mirror finish This finish is obtained by producing DOLUFLEX® panel from aluminum with mirror surface sheet made through a special anodizing process. Otherwise, in order to ensure more use resistant finishes it is possible to cover the panel with polished or super-mirror stainless steel sheets.

DOLUFLEX® panels is mainly made of aluminum, but can be also made of galvanized or stainless steel. SHIPBUILDING
