Steel HEB 240 beams with special high-strength connection. A vertical junction plate U 240 x 115 x 15. Centring DIAMETER 130 x 15. Special nut @ 40 x 28 M 22 (high-strength bolt). The two or more beams are bolted firmly together (M 22 x 50). This rigid connection applies particularly to areas where vibrations and shear stresses are especially great. <IMAGE>
