How to Fix and Prevent Roof Leakage in Light Steel Structures

-

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 ...

 The glass of the dome needs to consider a number of aspects of the selection of requirements to ensure that it meets the safety, functionality, aesthetics and energy efficiency of the building. The following is a detailed analysis of the requirements for the selection of glass for domes: dome 1. Safety requirements Strength and Impact Resistance: Dome glass must have high strength and impact resistance to resist external impacts such as wind, rain, snow, hail and possible accidental impact. Tempered and laminated glass are common choices because of their high strength and better load resistance. Blast resistance: For locations that require a high level of security, such as public places or buildings near earthquake zones, glass with blast resistance, such as laminated glass, should be used. Even when impacted by external forces, laminated glass can remain intact, avoiding the scattering of fragments, thus safeguarding the safety of people inside the building. 2.functional require...

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...
