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 ...

What are the economic advantages of a space frame structure?

  The advantage of the space frame  structure is that all the components can be spliced and installed by the factory. It only takes 45 days to 2 months for the roof of a large-scale industrial plant, and 8 to 12 months if the reinforced concrete building is used. The short project cycle greatly reduces unnecessary costs.   Because the weight of the space frame  itself is light, under normal circumstances, it is not necessary to do pile foundations, which can save investment. According to the current domestic market price in China, the cost of light steel structure is already lower than that of reinforced concrete structure. When the span of the space frame  structure is larger, the use space can be greatly increased, and its advantages are more obvious, which is also one of the competitions it relies on. big advantage.   Generally, the truss can be designed with a span of about 20 meters, and the supporting columns should be placed. However, the span of the...

Common connection methods for steel structures

-

Common connection methods for steel structures : 1. A steel structure is made up of a number of elements combined. The role of the connection is to combine the plates or sections into members in a certain way, or to combine several members into a whole structure in order to ensure that it works together. Therefore, the connection method and its quality directly affect the working performance of the steel structure. 2. At present, the steel structure is commonly connected by welding, bolting or riveting. The earliest common bolt connection was used from about the middle of the 18th century, and the rivet connection was introduced in the 1920s, while the weld connection appeared in the second half of the 19th century. Since the middle of the century, high-strength bolted connections have been developed.

Application Status of Large Span Space Frame Structures As we all know, the large-span spatial structure is a structural form with broad development prospects. In recent years, with the use of high-strength and lightweight materials, the development of structural design methods, construction technology and the application of computer numerical simulation analysis have created extremely favorable conditions for the development of large-span spatial structures. At present, the large-span space structure is widely used in a series of urban landmark buildings such as airports, gymnasiums, convention centers, and large commercial plazas, which reflects the current trend of world architectural concepts. The construction of space structures and the technologies used often reflect the level of a country's building science and technology. Some large-scale, novel and technologically advanced large-scale space structures have also become important symbols of a country's economic strength...

What is the new technology for removing rust from steel structures and equipment? Rust removal 1 、 Rust removal and corrosion prevention Rust removal is the main focus, equivalent to the highest standard of GB8923 Sa2.5/St3 Grade, as the base layer of paint, can significantly extend the corrosion prevention cycle of paint. 2、Paint compatibility It can be matched with any paint without wrinkling. For example: various anti-rust paints, epoxy  zinc-rich paint, epoxy iron paint, chlorosulphonated polyethylene paint, fireproof paint, atomic  ash, etc. 3、Bonding power The anti-rust layer formed after rust removal has a microscopic reticulated structure, which is easy for paint molecules to  penetration and macroscopic roughness, which makes the resin bite strong and combines well with the steel substrate and paint. The strength is very good. 4、Safety The product is a thick yellow water-based liquid, non-toxic and non-flammable. It only works with rust. No chemical reaction wit...
