Essential Steps to Strengthen Steel Roof Anti-Corrosion

-
图片
  Outdoor steel roof structures serve as the primary protective barrier for industrial plants, warehouses, and commercial buildings, yet they are constantly exposed to harsh natural conditions—rain, snow, UV rays, high humidity, and even salt spray in coastal regions. Corrosion stands as the most significant threat to their durability, often resulting in peeling coatings, rusted steel, weakened structural integrity, and eventually, expensive repairs or full replacements. For facility managers and project contractors, boosting the corrosion resistance of outdoor steel roofs is more than just prolonging asset life; it’s about safeguarding operational safety and cutting down long-term maintenance costs. Below are practical, actionable strategies tailored to outdoor environments, designed to create a robust, long-lasting anti-corrosion shield for steel roof systems. Unlike indoor steel structures, outdoor steel roofs endure year-round exposure to unpredictable weather, making corrosio...

What are the characteristics of the space frame structure

-

space frame roof


  1. The space frame is a mesh structure composed of many steel bar. It is a high -end super -static space structure. The space frame structure can be divided into two types: flat space frame and curved space frame.
  2. The flat space frame is used more. The advantages are: space stress system, the pole parts are mainly axial force, reasonable force, good overall performance, large rigidity, and good shock resistance. There are fewer rod types, suitable for industrial production.
  3. Space frame can be divided into two types: cross truss system and corner cone system. The corner cone system is more reasonable and greater.
  4. The height and short -span of the space frame is generally about 1/15. Steel tubes are generally used, and nodes generally use ball nodes.

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...
