Product Description

   During the construction process of coal mines, a large amount of steel pipes and supporting steel structures are required to build the main shaft (vertical shaft), excavate the main roadway, divide the mining area, and establish the working face. The steel structure of coal mines is usually used for mine support, which has high requirements for the performance of steel and the quality of welding. In the past few years, Huilai has provided drawing splitting, material supply, welding finished products, pre installation, and on-site guidance for multiple coal mine projects both domestically and internationally, accumulating rich experience in the supply of coal mine steel structures.

Steel Structure

Steel structure is a structure composed of steel materials and is one of the main building structure types.

The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plate. welding, bolts or rivets are usually used between each component or component.

Because of its light weight and simple construction, it is widely used in industrial plants, municipal infrastructure construction, electric power, Bridges, offshore oil engineering, aerospace and other industries. Including bridge structure, plant roof beam column structure, bridge steel box girder(Steel Module), deck longitudinal beam, coal mine structure tower and so on.

In order to solve the rust prevention on the surface of steel structure, we can also provide shot blasting and painting treatment on the surface of steel structure, including epoxy paint, galvanizing and other processes to extend the service life of steel structure and improve the service performance.

The main inspection methods of welding are: magnetic particle inspection(MT), penetration  inspection(PT), UT testing , RT testing, etc.
