Common Steel Structure Installation Tips

  Professional installation is the key to ensuring your steel structure is safe, stable, and long-lasting—and these simple tips will help avoid common mistakes. First, start with accurate measurement and positioning: even small errors can lead to misaligned components, which weakens the structure and causes future problems. Always ensure all components (columns, beams, fasteners) are connected firmly: check bolts regularly to avoid loosening, and prioritize high-quality welding—poor welds are a major weak point. Pay attention to weather conditions: avoid installing steel components during heavy rain or strong winds, which can affect safety and installation quality. Finally, follow strict construction standards: don’t cut corners to save time, and have a professional inspect the structure before use. Good installation practices don’t just ensure safety—they extend the life of your steel structure and reduce maintenance costs later. Steel Structure Installation

 Bolt Ball Testing Methods

bolt ball



1, bolt ball and manufacturing bolt ball nodes need materials, its varieties, specifications, performance, etc. should comply with national product standards and design requirements.
Inspection methods: check the quality of the product qualified documents, Chinese signs and inspection reports, etc.
2、Bolt ball shall not have burn, crack and crease.
Inspection method: Sample part of each specification of bolt ball, observe with 10 times magnifying glass and surface inspection.
3, bolt ball thread size and thread tolerance should be in line with the current national standard provisions.
Inspection method: check a part of each specification of the bolt ball and measure it with a standard thread gauge.
4, bolt ball diameter, roundness, adjacent two bolt hole centre line angle and other dimensions and allowable deviation should be in line with the local steel structure acceptance regulations.
5、Inspection method: Sample a portion of each specification of bolt ball and check if it conforms to the specified value with calipers and indexing head gauge.

What is a coal bunker?

-

Coal bunker , is a structure used for storing coal. Coal bunkers play an important role in thermal power plants, coal mines and coal marshalling stations. Depending on the specific application scenario and design, there are various types of coal bunkers, such as circular coal bunkers, square coal bunkers and open coal yards. Safety Management of coal bunkers Preventing spontaneous combustion of coal: Since coal itself contains certain moisture and volatile substances, long-term exposure to the air may lead to spontaneous combustion, so the safe management of coal bunkers is of great significance in preventing spontaneous combustion of coal. Ensure the quality of coal: coal in the coal bunker usually needs to be stored for a long time, if not managed properly, it may lead to the decline in the quality of coal, such as sulphurisation, weathering and other phenomena, so it is necessary to ensure the quality of coal by strengthening the safety management of the coal bunker. Improve the eco...

What is the difference between a single-layer reticulated shell and a double-layerreticulated shell?

图片
  The differences between single-layer reticulated shells and double-layer reticulated shells are as follows: Structural Configuration   Single-layer reticulated shell: Composed of a single layer of members, with the members directly connected to form a grid structure . The node configuration is relatively simple, typically employing rigid connections that allow the members to bear not only axial forces but also bending moments and shear forces.   Double-layer reticulated shell: Consists of upper and lower parallel layers of members connected by web members, forming a truss-like structural system. The nodes are generally hinged, and the members primarily bear axial forces. Its configuration is relatively complex, requiring more members and nodes to ensure structural stability and load-bearing capacity. Structure Single-layer mesh shell: composed of one layer of rods, the rods are directly connected to form a mesh structure, the node structure is relatively simple, usually...

Structural Steel Bolting Balls: Connecting the Future, Securing the Cornerstone

-
图片
In the field of steel structure , bolted ball, as an innovative choice of connecting node, is gradually becoming the preferred solution in modern buildings and industrial facilities due to its advantages of easy installation, removable and reorganisable, and low maintenance cost. Compared with traditional welded balls, bolted balls not only simplify the construction process and improve efficiency, but also give the structure greater flexibility and sustainability, which is an indispensable and important component in modern steel structure projects. The core concept of the bolted ball connection technology is to use high-strength bolts to closely connect the components to form a stable and reliable node structure. Compared with welded ball, bolted ball connection does not require on-site welding and avoids thermal stress, deformation and weld quality problems that may arise during the welding process, thus improving the overall stability and safety of the structure. In addition, the bo...
