What steel materials are adopted for your power transmission tower?

We mainly use national standard Q235B, Q355B high-strength angle steel, Q420 steel for extra-high voltage projects. All raw materials come from large formal steel mills with complete material test reports, fully complying with GB/T2694, IEC and ASTM international standards.

Can you customize tension tower, crossing tower and other types of transmission towers according to project drawings?

Yes. Our professional engineering team can design and produce Flying Angle Tower, Terminal Tower, Transposition Tower, Branching Tower and other lattice towers. We support OEM & ODM, customize height, voltage grade, wind & ice load parameters to match mountain, coastal, river-crossing working conditions.
