Communication Tower

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. The Company locates in No. 19 Anqiu Qinglong Lake West Road Anqiu Economic Development Zone, where lies on the southern of beautiful world kite capital -Weifang city, with beautiful scenery and convenient traffic.
Weifang Wuzhou Wind Power Equipment Co.,Ltd. was established by Weifang Power Supply Co., Ltd.'s subsidiary Shandong Wuzhou Investment Group Co.,Ltd. in December 2007,later renamed as Weifang Wuzhou Dingyi Steel Tower Co.,Ltd. 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, and have achieved Inner Mongolia electric power (Group) annual equipment material pre-qualification qualification certificate. We have production capacity and the relevant performance for 1100kV steel tower and we also have the right of import and export.
We have strong technical strength. 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 have 20 welding management personnel who have obtained the authentication Certificate from China State Grid Corp Steel Structure Welding Technological Guidance Committee and 101 personnel have obtained the steel grade Q460/Q345 Welding Certificate and we also have 121 professionals. Besides we employed some experts from china famous design institutions as our technical consultant and they have supervised and guided well on the technological upgrading and product quality improvement of our Company. 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".
Our Company has 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.
All products have been implemented CAD design and scheme optimization. We have introduced the internal force analysis software TTA(IGT2.0) of the self-supporting steel tower, computer-aided Structural design software STWXP for steel tower, three-dimensional steel tower lofting software TMA, three-dimensional steel tubular tower lofting software LMA, cast-in-place pile design and Finite Element Analysis(FEA) software, and those software has greatly improved the production efficiency and design& lofting quality.
The Company has 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. (1100kV Changji-Guquan and 800kV Ximeng - Taizhou) 25134.69 tons of angle steel tower; Nine 1000kV UHV AC projects(YuhengExtension,QingzhouConverterStation,Ximeng-Shengli,Yuheng-Weifang,Mengxi-SouthTianjin,Ximeng-Shandong,Huainan-Nanjing-Shanghai,Zhejiang-Fujian,Anhui-Eastern Power Transmission) with total quantity of 64403.35 tons which includes 14982.24 tons of Angle steel tower, 45946.91 tons of tubular steel tower, 2700 tons of 198 meters large span tubular steel tower and 774.2 tons of the substation structure .
Advanced ERP microcomputer management system has been adopted in R&D, material supply, product sales, production planning, product processing, transportation, installation, and after-sales service and the other management functions. We insists on surviving by high quality, strict regulations and high-quality talents are our development basis, Strictly implementation each requirements of quality management have been strictly carried out, every aspect from raw materials entering into the factory to the final products delivery has been controlled effectively in order to ensure the realization of our quality policy and overall objectives, therefore we have won the "Anqiu mayor Quality Award" honorary title.
Our annual production capacity is as following: 1100kV and below of the various types of steel tower and frame a total of 125000 tons which includes 80000 tons of angle steel tower, 35000 tons of steel tubular tower (Pole) and other tower, 10000 tons of substation structure; 20000 tons of wind tower with capacity 750kW~3000kW, 5000 tons of steel structure workshop and 5000 tons of communication steel tower, 20000 tons of photovoltaic supporting brackets.
