Mining and Tunneling Steel Profiles (EAF ROUTED)

This EPD is an average EPD representative for the manufacturer's mining and tunneling steel profiles. There are four different products under this category, namely: TH Mining Profile, GI NO 120, TH Notched Clamps, and K profile as shown in the figures below.

The only input material for these products is steel billet. In addition, manufacturing related processes are very similar between the investigated products. Thus, they are grouped under a single EPD. Steel billets used in the manufacturing of the investigated products are produced 100% through Electric Arc Furnace (EAF) route.

Mining and tunneling steel profiles are widely used in underground mines and railroad/highway tunnels, providing not only a higher resistance but also a yielding support to stabilize the underground cavities.

One of the most significant advantages of TH profiles against I and H profiles is their ability to provide same high tensile momentum on both cross sections (X-X and Y-Y) throughout the profile. Besides the ease of assembly, dismantling and high performance at the junctions; they maintain full support during the decreasing cross section of the underground cavity by sliding on each other without major deformation. In our production facilities, TH profiles can be supplied as hot rolled bars of various lengths according to customer demand or as final products prepared according to usage area.
