The Major Cold (Dahan) is the last solar term of the 24 solar terms, usually occurring around January 20-21, when the sun reaches 300° longitude. During this time, cold waves frequently move south, making it the coldest period of the year and also the time with the least precipitation.
Depending on the building height and design requirements, frame structures, frame-braced structures, tubular structures, and mega-frame structures can be selected. The components can be made of steel, reinforced concrete, or concrete-filled steel tubes.
As we all know, steel structure is widely used in various industries due to its light weight, high strength and high construction efficiency.
In the construction process of steel structures, the quality of welds directly affects the stability and safety of the building. Different weld grades represent different strengths and load-bearing capacities, and choosing the appropriate weld grade is a crucial step in ensuring the quality of the project. According to the national standards of China, the quality grades of steel structure welds are divided into three levels: Level 1, Level 2, and Level 3.
The Laba Festival is one of China's traditional holidays and also a prelude to the Spring Festival. The character "腊" (là) symbolizes the end of one year's work and the beginning of the new year. On this day, families prepare Laba porridge, praying for peace and prosperity in the coming year. During this traditional festival, we not only reflect on the efforts and achievements of the past, but also look forward to the hope and development of the future.
In the field of modern construction, steel structure buildings are increasingly favored for their unique advantages. This article will introduce you to some basic knowledge about steel structure buildings, helping you to better understand this form of construction.
In 2025, as a leading supplier in China's steel structure industry, quality remains the cornerstone of Hengon’s market presence and customer trust. Strict quality control will continue to be one of our core strategies for development.
The common connection methods in steel structures are welding, bolting, and riveting. With the widespread application of steel structures in commercial and industrial buildings, welding has become the most common connection method. High-strength bolted connections have become the most popular, while riveting is gradually being replaced by the former two methods and is rarely used in practical engineering projects.
Steel structures and reinforced concrete structures are two common types of building structures in industrial construction. They have significant differences in terms of performance, maintenance costs, construction speed, and suitable application scenarios.
As our factory continues to strengthen its capabilities, Hengon is committed to ongoing innovation in improving production efficiency, reducing energy consumption, enhancing steel structure cleaning effectiveness, and promoting environmental sustainability.
When we think of the Winter Solstice, we naturally associate it with snow. In the steel structure construction industry, one important factor closely related to snow is snow load.
In steel structure construction and installation, different foundation types need to be chosen based on geological conditions, structural loads, and construction requirements. To help clients install projects more quickly and accurately, Hengon has compiled the following common foundation types for reference.
