輕型鋼結構通常有兩種：一種是用薄鋼板（厚 6毫米以下）冷軋的薄壁型鋼組成的骨架結構；一種是用斷面較小的型鋼（如角鋼、鋼筋、扁鋼等）制作桁架，再組成骨架結構；還有混合使用兩種方法組成的骨架結構。
There are usually two types of lightweight steel structures: one is a skeleton structure composed of thin-walled steel sections cold-rolled with thin steel plates (less than 6 millimeters thick); One method is to make a truss using smaller section steel (such as angle steel, steel bars, flat steel, etc.) and then form a skeleton structure; There is also a skeleton structure composed of a mixture of two methods.
薄壁型鋼在汽車、飛機和船舶的骨架結構上的廣泛使用，促進了輕型鋼結構在工業化體系建筑中的發展。
The widespread use of thin-walled steel in the skeleton structures of automobiles, airplanes, and ships has promoted the development of lightweight steel structures in industrial system buildings.
After World War II, the school building system with light steel structures such as CLASP and SEAC emerged in the UK, and the residential and office building system with light steel structures such as GEAJ emerged in France.
輕型鋼結構建筑輕盈,便于工業化生產,施工組裝快速、方便，特別適于要求快速建成和需要搬動的建筑，較多地用于學校、住宅、辦公、旅館、醫院以及工廠和倉庫等。須作好硅烷化磷化鍍鋅除銹處理，以提高后期養護耐久性。
Lightweight steel structure buildings are lightweight, convenient for industrial production, fast and convenient for construction and assembly, and are particularly suitable for buildings that require rapid construction and need to be moved. They are commonly used in schools, residential buildings, offices, hotels, hospitals, factories, warehouses, etc. It is necessary to carry out rust removal treatment for silane phosphating zinc plating to improve the durability of later maintenance.

輕型鋼結構建筑的結構形式受歐洲傳統的木構架建筑影響較大，常由薄壁型鋼或小斷面型鋼組合成桁架來代替木構建筑的墻筋、擱柵和椽架等。骨架的組合方式一般同建筑規模、生產方式、施工條件以及運輸能力有關。常見的有：
The structural form of lightweight steel structures is greatly influenced by the traditional wooden frame construction in Europe, often consisting of thin-walled steel or small section steel combined into a truss to replace the wall reinforcement, joists, and rafters of wooden structures. The combination method of the skeleton is generally related to the building scale, production method, construction conditions, and transportation capacity. Common ones include:
單元構件式建筑體系 建筑物由柱、墻筋、梁、擱柵、檁條、椽子和屋架等單元構件裝配成輕型鋼結構骨架，然后再加鋪屋面，安裝墻板和門窗等。骨架的節點多采用螺栓和接板固定。
The unit component building system consists of columns, wall reinforcement, beams, joists, purlins, rafters, and roof trusses, which are assembled into a lightweight steel structure skeleton. Then, the roof is laid, and wall panels, doors, and windows, etc. are installed. The nodes of the skeleton are mostly fixed with bolts and connecting plates.
為了加強組裝式骨架的穩定性，在必要的部位加支撐或可調節的交叉式拉桿。單元構件組裝的建筑，組裝靈活，運輸方便，可適應各種不同建筑空間組合的需要。但現場施工時間比其他幾種安裝方式長些。
In order to enhance the stability of the assembled skeleton, support or adjustable cross tie rods are added at necessary locations. The construction of unit component assembly is flexible in assembly, convenient in transportation, and can meet the needs of various spatial combinations of buildings. But the on-site construction time is longer than other installation methods.
框架隔扇式建筑體系 由薄壁型鋼龍骨組成的框架隔扇，用作墻體、樓板和屋面的承重骨架結構，來裝配成整幢的建筑。這種建筑的內外面層和內部保溫、隔熱層以及門窗等可以在工廠預制時安裝好，也可在施工現場待骨架裝配好后再進行安裝。
The frame partition type building system is composed of thin-walled steel keels and is used as a load-bearing skeleton structure for walls, floors, and roofs to assemble the entire building. The inner and outer surfaces, internal insulation, insulation layers, and doors and windows of this type of building can be installed during factory prefabrication, or installed after the skeleton is assembled on the construction site.
這種建筑體系如同板材裝配式建筑，要求隔扇的規格類型少，節點裝配方便。由于大部分工作可在工廠完成，所以質量較高，現場施工速度較快。 盒子組合式建筑體系 在工廠用薄壁型鋼組裝成一個房間大小的盒子骨架，完成內外裝修并作好內部絕緣層，甚至可以把室內裝修，包括燈具、窗簾、地毯、衛生設施，以至固定家具等都在工廠安裝好。
This building system is like a prefabricated building made of panels, requiring fewer specifications and types of partition fans, and convenient node assembly. Due to the fact that most of the work can be completed in the factory, the quality is high and the on-site construction speed is fast. The box combination building system is assembled into a room sized box skeleton using thin-walled steel in the factory, completing internal and external decoration and providing internal insulation layer. It can even install indoor decoration, including lighting fixtures, curtains, carpets, sanitary facilities, and even fixed furniture, in the factory.
