Our company manufactures over 100 towers annually, utilizing materials including stainless steel, duplex steel, clad steel, low-temperature steel, chrome-molybdenum steel and special alloys. The heaviest tower we have produced weighs over 2,600 tons with a diameter of 11 meters. In March 2025, we completed the fabrication of a wash tower for the EPC project of the 1.5 million tons per year ethylene and downstream deep processing complex, which is part of the ethylene oxide and ethylene glycol unit. This equipment, weighing 2,650 tons, standing 110 meters tall and with a diameter of 10.2 meters, is constructed from Q345R+S30403 clad steel and is the world's largest tower of its kind for such a facility to date.

Our company is equipped with an out-of-gauge equipment workshop located near the Zhangjiagang Gangxin Port. This enables us to manufacture equipment with large diameters and heights that cannot be transported via road. The workshop houses the largest heat treatment furnace in South China, measuring 31m in length, 13m in width and 13m in height, capable of meeting the heat treatment requirements for out-of-gauge equipment.
