Rostirolla’s new GNW interlocking system is a simple, fast, and flexible hanging solution, ideal for loading small parts.

In a period such as the one the manufacturing industry is currently going through, where every day companies are confronted with the scarcity of raw materials and components of all kinds and with the extension of delivery times even for simple but sometimes essential products, having easy-to-use and extremely flexible tools at one’s disposal becomes of paramount importance. In a paint shop, the hanging of workpieces is one of the most important operations; to handle it at best, operators need tools such as hooks, racks, and other accessories on a daily basis. Whereas, for hooks and masking systems, coaters can usually count on suppliers with well-stocked warehouses or on averagely fast delivery times, the situation is different in the case of racks, as their design, sampling, and production times often hardly fit the demands of a fastpacing industry. Being able to manage the hanging of a new workpiece to be coated in the best possible way and, above all, autonomously becomes therefore essential, because it leads to greater efficiency of the entire painting cycle and, consequently, to considerable energy savings.

Rostirolla Srl has established itself in the coating sector as a manufacturer of hooks, frames, racks, masking systems, and other accessories since 1990. Its products are designed by its highly specialised technical department and manufactured in its dedicated machining department, equipped with state-of-the-art and continuously upgraded machinery. The company also offers customised and easily applicable solutions. In fact, its technical department is constantly searching for systems that can meet the most diverse and particular needs of users. The latest innovation patented by Rostirolla is the new GNW system, designed to interlock harmonic steel hooks and/or springs to a punched sheet metal support, on which various accessories can be combined to form a rack for hanging workpieces before coating. GNW is an extremely flexible tool that enables end users to independently solve any hanging issues on their coating lines.

GNW bars

The hook-holding bars are made of punched sheet metal with a thickness of 1.5 mm, bent for higher strength. They are available in standard widths of 600, 700, 800, and 1000 mm with a hole for hook insertion every 20 mm.

GNW frames

The robustness of the frames is guaranteed by the material they are made of, i.e. S355R steel with a diameter of Ø10 mm. Each component is wire-welded. The frames are available in standard widths of 600, 700, 800, and 1000 mm, while their height can be customised according to user requirements up to 2200 mm. The standard spacing between bar supports is 100 mm, but it can be modified upon request. Handles are generally customised according to customer requirements.

The MS.0026.1 component serves both as an interlock and as a protection.

GNW hooks and springs

Rostirolla manufactures hooks and springs for the GNW frames inhouse. They are made in C70 steel with a diameter of 1.5 or 2 mm. They can be easily inserted into the hanging system with a very high frequency rate of about 400-450 elements per hour, depending on their type.

Accessories

The MS.0026.1 side interlocking component is made of rigid silicone and has two main functions: it serves both as an interlock for the bar on the frame and as a mask for the electrical contact. The MS.0026.2 silicone cap was designed to protect unused bar supports. Once inserted into the punched holes, the hooks can be protected with a special sheath from the MS.0028.4 series.

GNW system’s compatibility with P20/P25 columns

The horizontal bars are compatible with the P20/P25 columns manufactured by Rostirolla for hanging small parts. The combination of the new GNW interlocking system and the P20/P25 columns further speeds up the loading of components by utilising the available space in the paintshop in the most efficient way.

Special projects

The GNW horizontal bars are mass-produced by cold forging and therefore cannot be customised; however, they can be shortened manually to suit special requirements and welded onto any structure according to customer needs.
