Weifang Wuzhou Dingyi Steel Tower Co., Ltd.

Weifang Wuzhou Dingyi Steel Tower Co., Ltd. Is specialized in manufacturing wind power tower, transmission line tower(we can manufacture the 1100 kV and below steel tower and 3000 kW wind power tower), broadcasting communication steel tower and mast, photovoltaic supporting bracket.

Our registered capital is 106, 000, 000RMB, our workshop area is more than 100000 square meters. We have a staff of 720. We own manufacturing license certificates of 750kV transmission line tower, communication tower and we have 3rd level qualification of steel structure specialized contract. We already have passed the quality, environment, occupation health and safety management system certification and State Grid supplier qualification site audit, and have obtained the Qualification Performance Verification for State Grid angle steel tower, tubular steel tower, substation structure and have passed the southern Power Grid Corp Level-A material supplier document review. We have production capacity and the relevant performance for 1100kV steel tower and we also have the right of import and export.

We were recognized by Weifang city as "enterprise technology center" and "Weifang green hot-DIP galvanized engineering technology research center", "Weifang Engineering Laboratory". We have one committee member from "National Overhead Line Standardization Technical committee", one committee member from "Power Transmission Branch Committee of Chinese society of Electrical Engineering", one committee member from"Branch Director of Tower Mast Steel Structure of China Steel Structure Association". We are main participant in the standard compiling of<Flange used in The Transmission line Steel Tubular Tower>, <Manufacture Technical specification for Cylindrical Tower of wind turbine generator>and we also have participated in the compiling of national standards and industry standards such as DL/T5130_2001<Design Technical Regulation of Steel Tube Pole for Overhead Transmission line>, <Design Technical Requirement of Steel tubular Tower for Transmission Line >, <Ultrasonic Inspection and Quality Evaluation to butt-jointed seam of thin walled pipe for steel tubular tower of power transmission line>.

We have undertaken the welding and processing compile work of power industry new standard "Welding Technology Guidance of Power Transmission Line Steel Tubular Tower", "Processing Technical Regulation of Power Transmission Line Steel Tubular Tower" which is being audited, and it will be the first important standard to regulate the welding and processing technology standardization of domestic steel tubular tower manufacturing industry.

We have the domestic first-class strength in the respect of transmission tower manufacture, especially in the development and manufacture of UHV transmission steel tower, with the world′s leading level.

We have totally won the bidding for UHV projects with a total of 89538.04 tons from 2012 to the present which includes two UHV DC project.
