 Corrosion Protection Process for Steel Structures Corrosion protection processes for steel structures are essential for ensuring that steel structures remain in good condition over the long term. This article provides a detailed overview of the various steps involved in these processes, including surface preparation, priming, coating application, quality control, and final inspection and acceptance. Surface treatment Surface preparation is the first step in the corrosion protection process. Its primary purpose is to remove dirt, grease, rust, and other contaminants from the surface of steel structures to improve coating adhesion and corrosion protection. Surface preparation includes the following steps: Cleaning: Removing grease, dirt, and dust from the surface of steel structures using solvents or detergents. Degreasing: Removing grease and wax-like substances with an alkaline degreaser to improve coating adhesion. Rust Removal: Removing rust and other corrosion products from the...

What Are The Architectural Features Of The Space Frame Fabrication?


Buildings processed by space frame are a good form of construction, because the materials used are mainly metal, which have better toughness than other materials. This will not only help enhance the load-bearing capacity of the building itself, but also shorten the construction period. To reduce the difficulty of construction, let's talk about the characteristics of space frame production buildings：


space frame


1. The components of space frame has good mechanical properties, and its stiffness and overall stability are better than those of general planar structures.

2. The space frame structure has certain regularity and is convenient for construction. There are a large number of same form components and nodes in the space frame structure, which brings convenience to factory production and structural installation, ensures the quality of the project, accelerates the installation speed of the construction site, and meets the strict requirements of the construction market on the construction period and project quality.

3. The space frame structure is multi-directional force. This force mode changes the force state of the plane structure, so that the material can more effectively play the role of the space frame structure as a spatial hinged bar structure. These rods mainly bear axial forces in different directions, and their cross-sectional dimensions are relatively small. These spatially intersecting parts support each other, and the force-bearing parts and the supporting system are organically combined, and high economic effects can be obtained. 

4. The building has great rigidity and seismic performance because of the overall mechanical properties of all components in the space frame structure. 

5. The space frame structure has so many advantages, including beautiful structure, light and generous, flexible layout. And also, it can meet the building function and modeling requirements, especially for the construction function of large-span, large-pillar net roof. Its superiority is even more prominent.

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?

  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...

What are the differences between bolted ball grids and welded ball grids?

 There are a number of differences between bolted ball grids and welded ball grids in terms of fabrication, construction and design. The following are specific comparisons: 1. Manufacturing process: The manufacturing of bolted ball net frame is mainly carried out in the factory, using mechanical shot blasting to remove rust, and then spraying paint, plastic spraying or zinc spraying treatment to enhance corrosion resistance.  The steel pipe and welded seam of welded ball mesh frame can only be descaled manually on site, and then paint or fireproof coating is brushed. For the welded part, it needs to be descaled and brushed at a stage to maintain, which increases the cost of later use and affects the safety of the structure. 2. Construction process: 70% of the workload of bolted ball grid frame is prefabricated in the factory, 30% of the workload is installed at the site, only a wrench is needed to tighten the bolts at the site, which is easy and fast, and can be constructed ...
