The steel angle is a carbon structural steel for construction. It is section steel with a simple cross-section. It is mainly used for metal components and the frame of the workshop. It is required to have good weldability, plastic deformation performance and certain mechanical strength in use. The raw steel billet for the production of angle steel is a low-carbon square billet, and the finished angle steel is delivered in the form of normalized or hot rolled.
Steel angle bar can be made into pressure structural bracket based on different size and grade, and also can be made into connector between structural beam. Widely used for various building structures and engineering structures, such as house beams, bridges, power transmission towers, lifting, and transportation machinery, ships, industrial furnaces, reaction towers, container racks, cable trench brackets, power piping, busbar bracket installation, and warehouse shelves.
Equal and unequal are the two major types of steel angle:
Steel angles are fashioned using a single Flat Steel section and bending it, generally at a 90-degree angle with both legs the same size. See below for a rundown of the different steel angle types:
Equal angle
Equal steel angles have 2 axes` that are the same length, hence their name. They are the most common types of steel section and can be made to various specs and cut to any size, making them extremely versatile. Their sizing is represented by side A x side B x thickness.
Unequal angle
Unequal steel angles are also right-angled; however, they have different sized axis` making them L-shaped. This section is much stronger (up to 20%) with a much higher strength to weight ratios. Their sizing is represented by side A x side B x thickness.

After 11 years of R&D, 5 years of on-line testing, and continuous improvement, the new energy automotive industry in Fuyang has opened up. Dongfeng Liyang Wagon Co., Ltd. announced on June 29, 2014 that eight new energy vehicles, including EQ6102HBEVA pure electric city buses, independently developed by the company entered the Catalog of New Energy Automobile Products of the Ministry of Industry and Information Technology. This means that these eight kinds of new energy vehicles have obtained "passes" for entering the national market.
It is understood that Shenyang has now formed 400,000 complete vehicles, 850,000 sets (sets) of engines, and 1.4 million axles. The industry scale and technology reserves are strong. According to Gong Jun, an expert on major electric vehicle projects during the “12th Five-Year Planâ€, as one of the pilot cities for the demonstration and operation of new energy vehicles nationwide, Liyang has a strong new energy automotive industry foundation and can completely “step ahead of others†in research and development of new energy vehicles. ".
Based on the state's subsidy policy, Fuyang has introduced a New Deal. Each municipality sells a car classified in the Ministry of Industry and Information Technology's automotive product catalog. The municipal government subsidizes the company by 200,000 yuan, giving priority support to project construction. The new energy bus running in Fuyang City is given an operating subsidy of 30,000 yuan per year, which inspires the acceleration of the new energy automobile industry. Many companies have started to take advantage of Liyang.
At present, Xiangyang is engaged in the research, development and production of new energy vehicles in more than 30 enterprises and institutes, and has nearly 200 patents and practical technologies independently researched and developed. More than 100 patents and practical technologies have been successfully used in process manufacturing. The “two vertical and three horizontal†industry pattern of pure electric vehicles, plug-in hybrid vehicles, power batteries, drive systems, and control systems has a total investment of over 10 billion yuan. It is estimated that by 2016, new energy vehicles will have a production capacity of 160,000 vehicles.
Promotion and application have also made breakthroughs. The pure electric city bus developed by Dongfeng Wagons Co., Ltd. has been operating online since the end of 2009, and its cycling distance has exceeded 100,000 kilometers. The cumulative safety operation of 87 pure electric city buses operating on 5 bus lines exceeded 5 million kilometers, with an average of 100 kilometers and a power consumption of 76 kilowatt-hours. According to 0.98 yuan/kWh, the operating cost per 100 kilometers was only 74.48 yuan. The safe operation distance and the 100km power consumption index rank the first in the industry in the pure electric bus industry.
