Production information
Steel structures are capable of constructing single-story buildings, such as steel warehouses, workshops, and storage. They can also be employed to build double-story or even multi-story structures. The use of steel structures in the construction of multi-story buildings has the characteristics of rapid construction, strength superiority, and flexibility. It is suitable for a wide range of construction projects, including commercial office buildings, residential buildings, and public buildings.
The steel building we intruduce here is also a 4-story building for an office metal building. It's steel main frame composed of H-section steel structure, and then use the light-weight concrete block as the wall. 1.0mm thick galvanized floor decking is used as the floor plate. Add re-bars, and pour 120~150mm concrete directly. This kind of making method is similar to traditional buildings, but the installation is generally much simpler and faster than conventional buildings. It can meet the earthquake and wind resistance requirements of different countries.

Steel building techniques
Steel building techniques include structural design, fabrication, welding, assembly, and installation. That refers to the methods and processes used in the construction of steel buildings. Steel is a durable and robust material that can support large spans and heavy loads, making it suitable for a wide range of construction projects. Steel has strength, versatility, and cost-effectiveness, making it a reliable and long-lasting choice for various applications.
Steel buildings application
Commercial Buildings: This includes office buildings, shopping malls, hotels, exhibition centers and entertainment venues.
Industrial Buildings: Such as factories, warehouses, logistics centers and manufacturing facilities.
Public buildings: Such as schools, hospitals, sports venues and cultural centers.
Residential buildings: They can be used in apartment buildings, high-rise residences, villas and residential complexes, etc.
Steel structue construction building advantages
Strength and Rigidity: Steel has high strength and rigidity and is able to withstand large loads bending forces earthquake proof and wind resistance, which makes the high structural safe.
Long-span design: Steel structures do not require too many support columns inside the building, allowing for more flexible interior space layouts and the ability to create open, spacious environments.
Fast construction: Steel-framed multi-story buildings feature prefabricated steel components fabricated in factories and then quickly installed and assembled by bolts on site.
Why are we using H beams more than I beams for a metal/steel building?
1. H beams are straightforward and have better mechanical properties than I beams.
2. H beams are easier to fabricate than I beams because of their straight outer flanges.
3. The H beam is lightweight but stronger than the cross-section of the I beam.
4. I beams are usually beams but H beams can be used as load-bearing columns or beams.
