According to customer demand and desired gallery sections, bended TH / K / GI and IPN / HEA profiles and traversal junctions are produced.
GI profiles are offered to our customers in special section and special rolled form.
TH mining 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.
K 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.
