Report Number(s): Test No. E23-0800, E23-0645, E23-0617

Description: TRION DA S2-TL4 MASH is a high containment guardrail made entirely of galvanized steel, consisting of thrie beam rails supported by steel posts with steel spacers. The three-beam rails, posts, and spacers are made of hot-rolled steel sheet with quality S355JR according to EN ISO 10025 and are hot-dip galvanized according to EN ISO 1461. The thrie-beam has a nominal thickness of 2.5 mm. The posts have a C section of 125x80x25 mm, with a nominal thickness of 4.5 mm and a length of 1950 mm. The spacers have a C section of 100x60x25 mm, with a nominal thickness of 4.5 mm and a length of 290 mm. For installation, the top of the thrie-beam rail is located 1000 mm above the ground. The posts are placed every 1.905 m and are installed at a height of 940 mm from the ground. The fixing screws between the thrie-beam rail and the spacers are TBC M16x50 class 8.8 round head bolts, 100x40x5 mm rectangular plates of S235JR quality according to the EN ISO 10025 standard, M 16 washers, and M 16 nuts, following the UNE 135122 standard. Spacers are screwed to the posts using CRF-10.5 M 16x50 class 5.8 round head bolts, 100x40x5 mm, and 35x35x5 mm rectangular plates of S235JR quality according to EN ISO 10025 and Ml 6 nuts following the UNE 135122 standard. Thrie-beam rails use TBC M16x30 class 5.8 round head bolts, Ml 6 washers, and Ml 6 nuts, following the UNE 135122 standard. The CRF-10.5 M 16x50 bolts that join the spacer and the post are tightened with a torque between 30 Nm and 50 Nm. The bolts that join consecutive fences and those that join the spacers and rails are tightened with a torque between 80 Nm and 100 Nm.
