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。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。第二次世界大戰后，英國出現了CLASP和SEAC輕型鋼結構的學校建筑體系，法國出現了GEAJ等輕型鋼結構的住宅和辦公室建筑體系。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。但須作好防銹處理并加強養護，以提高耐久性。

There are usually two types of lightweight steel structures: one is a skeleton structure composed of thin-walled steel sections cold-rolled from thin steel plates (with a thickness of less than 6 millimeters); One method is to use smaller cross-sectional steel (such as angle steel, steel bars, flat steel, etc.) to make trusses and then form a skeleton structure; There is also a skeleton structure composed of a mixture of two methods. 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 industrialized construction systems. After World War II, the school building systems of CLASP and SEAC lightweight steel structures appeared in Britain, while the residential and office building systems of GEAJ and other lightweight steel structures appeared in France. Lightweight steel structure buildings are lightweight and easy to industrialize, with fast and convenient construction and assembly. They are particularly suitable for buildings that require rapid construction and movement, and are commonly used in schools, residences, offices, hotels, hospitals, factories, and warehouses. But it is necessary to carry out rust prevention treatment and strengthen maintenance to improve durability.

抗震性：低層別墅的屋面大都為坡屋面，因此屋面結構基本上采用的是由冷彎型鋼構件做成的三角型屋架體系，輕鋼構件在封完結構性板材及石膏板之后，形成了非常堅固的“板肋結構體系”，這種結構體系有著更強的抗震及抵抗水平荷載的能力，適用于抗震烈度為8度以上的地區。

Seismic resistance: The roofs of low rise villas are mostly sloping roofs, so the roof structure is basically a triangular roof truss system made of cold-formed steel components. After sealing the structural panels and gypsum boards, the light steel components form a very strong "plate rib structure system", which has stronger seismic resistance and resistance to horizontal loads, and is suitable for areas with seismic intensity above 8 degrees.

抗風性：輕型鋼結構建筑重量輕、強度高、整體剛性好、變形能力強。建筑物自重僅是磚混結構的五分之一，可抵抗每秒70米的颶風，使生命財產能得到有效的保護。

Wind resistance: Light steel structure buildings have light weight, high strength, good overall rigidity, and strong deformation ability. The self weight of a building is only one-fifth of that of a brick and concrete structure, and it can withstand a hurricane of 70 meters per second, effectively protecting life and property.

耐久性：輕鋼結構住宅結構全部采用冷彎薄壁鋼構件體系組成，鋼骨采用超級防腐高強冷軋鍍鋅板制造，有效避免鋼板在施工和使用過程中的銹蝕的影響，增加了輕鋼構件的使用壽命。結構壽命可達100年。

Durability: The light steel residential structure is entirely composed of cold-formed thin-walled steel components, and the steel frame is made of super anti-corrosion high-strength cold-rolled galvanized sheet, effectively avoiding the influence of steel plate corrosion during construction and use, and increasing the service life of light steel components. The structural lifespan can reach 100 years.

保溫性：采用的保溫隔熱材料以玻纖棉為主，具有良好的保溫隔熱效果。用以外墻的保溫板，有效的避免墻體的“冷橋”現象，達到了更好的保溫效果。100mm左右厚的R15保溫棉熱阻值可相當于1m厚的磚墻。

Thermal insulation: The insulation material used is mainly fiberglass cotton, which has good thermal insulation effect. The insulation board used for exterior walls effectively avoids the "cold bridge" phenomenon of the wall and achieves better insulation effect. The thermal resistance value of R15 insulation cotton with a thickness of about 100mm can be equivalent to a brick wall with a thickness of 1m.

隔音性：隔音效果是評估住宅的一個重要指標，輕鋼體系安裝的窗均采用中空玻璃，隔音效果好，隔音達40分貝以上；由輕鋼龍骨、保溫材料石膏板組成的墻體，其隔音效果可高達60分貝。

Soundproofing: Soundproofing effect is an important indicator for evaluating residential properties. The windows installed in the light steel system are made of insulated glass, which has good sound insulation effect and can achieve sound insulation of over 40 decibels; The wall composed of light steel keel and insulation material gypsum board can achieve a sound insulation effect of up to 60 decibels.

健康性：干作業施工，減少廢棄物對環境造成的污染，房屋鋼結構材料可100%回收，其他配套材料也可大部分回收，符合當前環保意識；所有材料為綠色建材，滿足生態環境要求，有利于健康。

Health: Dry construction reduces the pollution caused by waste to the environment. The steel structure materials of the house can be 100% recycled, and most of the other supporting materials can also be recycled, which is in line with current environmental awareness; All materials are green building materials that meet ecological and environmental requirements and are beneficial to health.

舒適性：輕鋼墻體采用高效節能體系，具有呼吸功能，可調節室內空氣干濕度；屋頂具有通風功能，可以使屋內部上空形成流動的空氣間，保證屋頂內部的通風及散熱需求。

Comfort: The light steel wall adopts an efficient and energy-saving system, with breathing function and the ability to adjust indoor air dryness and humidity; The roof has ventilation function, which can create a flowing air space above the interior of the roof, ensuring the ventilation and heat dissipation needs inside the roof.

快捷：全部干作業施工，不受環境季節影響。一棟300平方米左右的建筑，只需5個工人30個工作日可以完成從地基到裝修的全過程。

Quick: All construction work is done without being affected by environmental seasons. A building of about 300 square meters can complete the entire process from foundation to decoration in just 5 workers and 30 working days.

環保：材料可100%回收，真正做到綠色無污染。

Environmental Protection: Materials can be 100% recycled, truly achieving green and pollution-free.

節能：全部采用高效節能墻體，保溫、隔熱、隔音效果好，可達到50%的節能標準。

Energy saving: All use high-efficiency energy-saving walls with good insulation, heat insulation, and sound insulation effects, which can reach 50% energy-saving standards.
