INTRODUCTION
The steel structure is the bearing structure of construction works designed and constructed with steel. This type of structure is widely used in the construction industry, especially in large-scale construction works (Pre-engineered steel buildings) because of the useful properties of steel. Thanks to the high strength of steel, this structure is very strong and requires less material than other types of structures such as concrete structures or wooden structures.
Steel has the good bearing capacity as well as good compression. Therefore, steel will be lighter than concrete. This is the great advantage of steel. Today, this structure is used for almost all types of buildings. Including industrial, residential, office and commercial buildings. Steel is also used as a tower structure. Examples are node towers for cellular networks, radars and telephone relay towers.

STEEL STRUCTURE APPLICATION
Large span houses, which are houses that require large spans over 30-40 m, such as concert halls, gymnasiums, sports halls, exhibition halls, hangars, etc. bearing steel are the most reasonable.
Multi-story house frames, especially tower-shaped houses in cities. When the house is over 20-30 floors, the internal force in the column will be very large. Requires high rigidity, using steel frames is more beneficial than reinforced concrete frames.
Road bridges, railway bridges, are made of steel with the medium span, large spans when fast construction is required. The steel suspension bridge can span very large spans over 1000m.
High tower structures, such as electric poles, radio antenna masts, survey towers, or some special structures such as oil drilling towers. Using steel here is beneficial because the structure is light, easy to transport, easy to erect.
Kết cấu bản, như các loại bể chứa dầu, bể chứa khí, các thiết bị của lò cao, của nhà máy hóa chất, nhà máy hóa dầu. Đây là phạm vi ứng dụng đặc biệt có lợi, vì tính kín, chống thấm của kết cấu thép , vì khả năng làm việc trong những điều kiện bất lợi về nhiệt độ và áp suất.
Các loại kết cấu di động, như cần trục, cửa van, gương ăng ten Parabon… cần trọng lượng nhẹ để có thể di chuyển, nâng cấp trước dễ dàng.

Why choose Steel Structure?
Steel has a natural beauty that most architects love. Steel structures can create large-span space trusses, lots of natural light, high aesthetics and architecture.
Steel is an easy-to-form material, which is the first choice for projects that require high aesthetics. Not only strong, but steel is also very flexible in construction and elegant, bringing beauty to the building.
The steel structure has the high bearing capacity and high reliability. Can withstand extreme forces or extreme weather conditions, such as strong winds, earthquakes, storms and snowfall. This structure is also not susceptible to rust and unlike wooden frames, they are not affected by termites, bugs and mildew.
Due to its lightweight and great rigidity, it is easy and quick to transport and assemble steel structures. Can be modified in the future for new applications, loading conditions, vertical expansion, changes according to the owner's requirements that other framing systems cannot do.
Fabricated in the factory and quickly assembled on-site by skilled staff. This facilitates the construction process to take place in absolute safety. Minimize loss of construction materials.
The steel structure is considered the most economical option in terms of design and material costs. This type of structure costs very little in manufacturing, erection and maintenance compared to traditional methods.
