How to Fix and Prevent Roof Leakage in Light Steel Structures

-
图片
Roof leakage is one of the most common problems in light steel workshops and warehouses. It not only affects daily use but also causes internal corrosion, shortens the building’s service life, and leads to higher maintenance costs. Most leakage happens at panel joints, screw holes, flashing areas, or around openings. The main reasons are poor waterproof treatment, aging sealant, loose screws, or improper installation. To fix existing leaks, first clean the surface and locate the leakage points. Replace damaged or aging sealing strips. Re-tighten loose screws or replace them with waterproof self-drilling screws. Apply professional waterproof sealant at joints and openings. For serious cases, add a layer of waterproof coating to improve protection. To prevent future leakage, use high-quality roof panels and waterproof materials from the beginning. Ensure professional installation with standard flashing and sealing design. Conduct regular inspections, especially before rainy seasons, and ...

space frame

Strong seismic performance: Steel has excellent seismic performance, providing greater safety in the event of an earthquake.


Lightweight and Strong: Steel has higher strength and stiffness than traditional materials such as concrete and masonry, while being relatively lightweight, reducing the overall structural weight and foundation requirements.


High flexibility: steel is easy to cut, bend and connect, and can realize various complex structural forms and adapt to different design requirements.


Short construction cycle: The production process of steel structure is highly industrialized and can be prefabricated in the factory, reducing the on-site construction time and improving the project progress.


Green and environmental protection: steel can be recycled and reused, which reduces the consumption of natural resources and conforms to the concept of sustainable development.


Beautiful and generous: steel structure can create a modern design effect with unique aesthetic charm.


Low maintenance cost: steel structure has a long service life and relatively low maintenance cost, which is economical in the long run.


Wide scope of application: Steel structure is not only suitable for large-span roofs, but also can be used in bridges, factories, stadiums and other types of buildings.


Strong expandability: steel structure is easy to expand or remodel, and the structure can be adjusted at any time according to the needs.


Good fireproof performance: The surface of steel can be coated with fireproof coating to improve its fire-resistant performance and enhance safety.


It should be pointed out that the use of steel structure also needs to pay attention to measures such as anti-rust and anti-corrosion to ensure the lasting stability of the structure. In addition, the design and construction process needs to follow the appropriate standards and codes to ensure the safety and reliability of the structure.

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...
