重型钢结构是没有一个统一的标砖的，基本常见的几种类型有：
Heavy steel structures do not have a unified standard brick, and the basic common types are:
每平米用钢量：大于等于50kg/m2，可以认为是重型钢结构；
Steel consumption per square meter: ≥ 50kg/m2, can be considered as a heavy steel structure;
主要构件钢板厚度：大于等于10mm，轻型钢结构使用较少，一般都是重型钢结构；
The thickness of the main component steel plate is 10mm or more, and light steel structures are rarely used, usually heavy steel structures;
厂房行车起吊重量：大于等于25吨，可以认为是重型钢结构
The lifting weight of the factory crane is greater than or equal to 25 tons, which can be considered as a heavy steel structure
轻型钢构造主要是用在不接受大载荷的承重修建。选用轻型H型钢，焊接或轧制，变截面或等截面，做成门形钢架支承。压型钢板或轻质夹芯板作屋面墙面围护构造，选用高强螺栓一般螺栓及自攻螺丝等连接件和密封资料拼装起来的低层和多层预制装配式钢构造房屋系统。轻钢构造住所构造悉数选用冷弯薄壁钢构件系统构成，钢骨选用超级防腐高强冷轧镀锌板制作，有用防止钢板在施工和使用过程中的锈蚀的影响，增加了轻钢构件的使用寿数。构造寿数可达一百年，很多的厂房都是由这样的钢结构材质制作而成。

Light steel structures are mainly used for load-bearing construction that does not accept large loads. Select lightweight H-shaped steel, welded or rolled, variable cross-section or equal cross-section, and make it into a door shaped steel frame support. A low-rise and multi-layer prefabricated prefabricated steel building system consisting of high-strength bolts, general bolts, self tapping screws, and other connectors and sealing materials assembled using profiled steel plates or lightweight sandwich panels for roof and wall enclosure construction. The residential structure of the light steel structure is entirely composed of cold-formed thin-walled steel component systems, and the steel ribs are made of super anti-corrosion high-strength cold-rolled galvanized sheet, which effectively prevents the corrosion of the steel plate during construction and use, and increases the service life of the light steel components. The construction lifespan can reach 100 years, and many factories are made of this steel structure material.
重型钢结构各构件或部件之间一般选用焊缝螺栓或铆钉衔接。因其自重较轻，H型钢结构房,双层结构房,重型钢结构结构首要由型钢和钢板等制成的梁钢钢柱钢桁架等构件组成。且施工简便，广泛使用于大型厂房场馆超高层等范畴。自重轻全体刚度好变形能力强，故用于缔造大跨度和超高超重型的修建物特别适合；大大提高其屈服点强度；此外要轧制新品种的型钢。
Weld bolts or rivets are generally used to connect the components or components of heavy-duty steel structures. Due to its relatively light weight, H-shaped steel structure houses, double-layer structure houses, and heavy-duty steel structure structures are mainly composed of beams, steel columns, steel trusses, and other components made of section steel and steel plates. Moreover, it is easy to construct and widely used in areas such as large factory buildings, venues, and super high-rise buildings. Lightweight, with good overall stiffness and strong deformation ability, it is particularly suitable for creating large-span, ultra-high, and ultra-heavy structures; Greatly improve its yield point strength; In addition, new varieties of section steel need to be rolled.
