Steel Works _ Peng Jian Steel (certified) _ Steel Ltd., Zhongshan, Dongguan City, Peng Jian provided by steel. Steel Co., Ltd., Dongguan City, Peng Jian (dgpengjian.cn) is specialized in the "Steel" of the enterprise, the company adhering to the "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Mr. Xu. Steel inherent problems; a unit in the processing of a building box columns 1200 * 1200 * 60 in the welding process appeared suddenly found 60mm tearing as the web plate, clearly visible crack the board split in half from the thickness direction, NDT inspection after cracks were found at a depth of 3mm depth occurred around the same time of the same type from the same batch cutting board another few parts for testing, found in a sandwich board memory, rolling is caused by poor quality mainly due to quality problems. In the process of welding the welding stress due to welding materials produced will mezzanine opened. Hence there are planks in the thickness direction of the phenomenon tear Cause Analysis: As part of the special nature of the use of steel, which is used as a component in the member web use, longitudinal welded components in the vertical direction welded formally opened The full penetration groove the force strength steel plate prices, due to the existence of a layered interior panels, welding welding stress generated thereby tearing out the release plate thickness direction. According to the actual situation can be taken several measures to deal with the following: steel building steel building strengths significant advantages, steel building will become the trend. Steel houses in Europe and America have decades of history, it is with good shock resistance, flexible and variable space, environmental protection and other strengths, to grow. It is a steel plant east if the main load-bearing member refers is composed of steel. Follow the progress of China's overall living standards, quality of housing, quality requirements will progress, steel housing will be popular. Machining high precision, short manufacturing cycle, producing high efficiency advantages, the construction industry is an indispensable sector steel company in the construction of the tower in Foshan, the application of steel construction of high buildings iconic objects, enough chaos, shock resistance, span Large steel structure installation, saving space, Guangzhou Steel Company in the application of light-based steel residential housing is mainly used in non-load-bearing construction to withstand large loads. Steel components smaller, lighter weight, easy to transport and install, easy assembly and disassembly, expansion, co-span steel structure for maintenance, high altitude, bearing the weight of the structure, Shenzhen, manufacture and installation of steel structures in terms of the company for the plant. Dongguan steel in heavy steel in the application can carry a large load bearing building.
