Bossong SpA is constantly conducting research and development not only on new materials and applications, but also keeping updated on regulatory aspects of fasteners in construction.
Focusing on heavy-duty anchors, Bossong has announced that two new heavy-duty anchors are now available on the market. These two new products are the new concrete screw CLS-CE and the new mechanical anchor NWS-CE1 – both of which have been assessed following the recent EAD 330232-00-0601.
The new concrete screw CLS-CE has a European Technical Assessment for cracked and non-cracked concrete (ETA – 17/0471), with seismic qualification in category C1 and with fire resistance R120. Available in a range of diameters – 6mm, 8mm, 10mm, 12mm and 14mm – the strengths of the CLS-CE concrete screw include a high mechanical performance and high flexibility in use – thanks to three different depths of installation for each diameter.
The CLS-CE requires small minimum distance between anchors and small minimum distance from the lower edges. Plus, a smaller hole diameter means a lower installation time is required in respect to other anchorage systems. There is also the possibility of adjustment after installation of the screw – the CLS-CE can be recoiled twice up to 10mm if the nominal embedment depth is guaranteed.
Available in galvanised and A4 stainless steel, three different kinds of heads are available – hex head, countersunk head and pan head. Each type of head has a different type of assortment, with different lengths and diameters.
Bossong’s other new product is the mechanical anchor NWS-CE1, which has been assessed for cracked and non-cracked concrete (ETA – 17/0506), has fire resistance R120, and also the seismic qualification in category C1 and C2 according to EAD 330232-00-0601.
The strengths of the new Bossong mechanical NWS-CE1 anchor include a very high mechanical performance and a wide range of diameters – 8mm, 10mm, 12mm, 16mm, 20mm, 24mm and 27mm. The NWS-CE1 also offers high flexibility thanks to two different setting depths and is available in galvanised steel, stainless steel A4 and high corrosion resistance steel HCR.
The main applications for both the CLS-CE and the new NWS-CE1 are shelves, base plates, railing, anchoring of equipment, and anchoring of beams or metal profiles.
