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 ...

Why do most of the stadium bleachers use truss structure?

  The reasons for adopting truss structure for stadium grandstand are as follows: truss roof 1. High strength : Joist structure is composed of multiple triangles, which can disperse the load and support the weight, with high strength and stability. 2. Lightweight : truss structure is usually made of lightweight materials, such as steel or aluminum alloy, which is light in weight and easy to transport and install. 3. Good flexibility : Joist structure can be adjusted and changed as needed to suit different sites and usage requirements. 4. Economical and practical : The manufacturing cost of joist structure is relatively low and the maintenance cost is also low, so it is economical and practical. 5. Beautiful and generous : Joist structure has simple and generous appearance and good aesthetics, which meets the aesthetic standard of modern architecture. _________________________________________________________________ Follow me and take you to learn more! 👇👇👇 www.safsteelstructure...

Features of truss

  From the perspective of material layout (or distribution), the truss can be regarded as a latticed beam as a whole, and its overall mechanical performance is similar to that of the beam. In the detail structure, each rod is used to re-direct the force flow (the nodes between the rods are not overlapped, and the bending moment cannot be transferred), and the overall layout is basically consistent with the main stress trace. Each rod is a secondary force rod, which is only subjected to tension and compression Truss, especially space pipe truss, is often made into arch. However, at this time, the arch is not a pure pressure arch, and the whole arch is still dominated by bending. We can also consider it as a curved beam in a certain sense. Of course, arch camber can increase the span capacity, and the role of "axial force" in the "beam" can not be ignored at this time, but in most cases, especially when the rise-span ratio is small, the bending is still the main part.

What is the truss welding method?

  truss roof Most of the rods in joist structures are welded at the nodes. Before welding, the webs and chords need to be cut in advance according to the shape of the weld seam of each member to be welded, which requires cutting of the web ends and slotting of the chords. Since the joist structure is intersected by coherent line between the rods and rods, the shape of rod end section is complicated, so in the actual cutting process, two methods of mechanical automatic cutting process and manual cutting process are generally used.

truss roof A truss refers to a lattice structure composed of round rods connected to each other at the ends. Wide range of applications and economical and practical today. Such as exhibition centers, stadiums or some other large public buildings have been used.   In recent years, with the continuous growth of my country's steel production, steel structures, with their own advantages, account for an increasing proportion of buildings, and steel pipe structures have also made great breakthroughs. The biggest advantage of the steel pipe structure is that it can perfectly combine the functional requirements, sensory requirements and economic benefits of people's buildings. The pipe truss structure in the steel pipe structure is favored by people with its unique advantages. ______________________ Whatsapp/Tel:+ 86/13056229023 E-mail:safs121@safsteelstructure.com www.safsteelstructure.com

 What is a truss? truss roof A structure in which rods are connected to each other by hinges at both ends. The truss is composed of straight rods and generally has a plane or space structure with triangular elements. The truss rods mainly bear axial tension or pressure, so that the strength of the material can be fully utilized. When the span is large, the material can be saved compared with the solid web beam, and the self-weight and weight can be reduced. Increase stiffness. __________________________ Whatsapp/Tel:+ 86/13056229023 E-mail:safs121@safsteelstructure.com Website:www.safsteelstructure.com/
