F.lli Razeto & Casareto unveils new nanoceramic handles at Metstrade 2026

At Metstrade in Amsterdam, F.lli Razeto & Casareto introduces a new generation of aluminium and stainless steel handles featuring the HNCF™ nanoceramic treatment. The technology enhances wear and corrosion resistance, thermal performance and the tactile properties of the surfaces.

F.lli Razeto & Casareto, an Italian company specialising in the design and manufacture of marine hardware, will present a new generation of handles made from aerospace-grade aluminium alloy and stainless steel at Metstrade 2026, taking place in Amsterdam from 17 to 19 November. The handles feature HNCF™ (Hard Nano-Ceramic Finishing) nanoceramic technology. Beyond its aesthetic function, the treatment modifies the components’ surface properties to improve mechanical resistance, thermal performance and comfort to the touch.

HNCF™ technology uses deposition and surface conversion processes that, depending on the alloys used, produce multilayer coatings offering high hardness, abrasion resistance, reduced friction and protection against corrosive agents. These properties are particularly relevant in marine environments, where salt, humidity, temperature fluctuations and frequent use place onboard hardware under constant stress.

A further area of development concerns thermal performance. Specific nanoceramic formulations can reduce heat transfer through contact, making handles more comfortable to use when exposed to particularly high or low temperatures. The research therefore aims to make metal components easier to use even in extreme climatic conditions, with potential applications both on board and in environments such as saunas, wellness centres and cold rooms.

In marine environments, nanoceramic coatings can also help limit galvanic corrosion where dissimilar metals are in contact, thanks to the insulating properties of specific formulations. Wear resistance and a low coefficient of friction offer further potential for use in mechanical components subject to repeated movement, such as the internal components of locks and locking systems.

Alongside these functional properties, F.lli Razeto & Casareto introduces the Oxyd Matt finish, featuring a matt surface with a Velvet Like tactile effect. The treatment combines the high hardness of the nanoceramic coating with a soft, velvety feel, bringing a sensory dimension to hardware design.

The research also explores the hygienic properties of surfaces. Thanks to their low porosity, certain nanoceramic coatings can limit the build-up of contaminants and facilitate cleaning. Specific formulations may also be developed to inhibit microbial growth or meet food-contact requirements.

Potential applications extend beyond the marine sector to include hospitality, healthcare facilities, wellness environments, architecture and industry, where corrosion resistance, thermal comfort and durability are important requirements.

Founded in 1920, F.lli Razeto & Casareto continues its research into materials and opening systems, with the aim of progressively extending nanoceramic treatments from handles to the mechanical components of locks.

The new solutions will be presented at Metstrade 2026, at RAI Amsterdam, stand 12.101.
