轻型钢结构常被宣传为“抗震抗风”，但口号听得再多，不如看具体数据。这些数据决定了它在极端条件下的真实表现。

Lightweight steel structures are often promoted as "earthquake resistant and wind resistant", but no matter how many slogans you hear, it's better to look at specific data. These data determine its true performance under extreme conditions.

抗震：适用于8度以上设防地区。 轻钢构件封完结构板材后，形成“板肋结构体系”，这种体系有更强的抗震及抵抗水平荷载能力，适用于抗震烈度为8度以上的地区。作为参考，汶川地震的震中烈度达到11度，8度设防意味着能抵御大多数破坏性地震。

Seismic resistance: suitable for areas with a fortification level of 8 or above. After sealing the structural plates with light steel components, a "plate rib structure system" is formed, which has stronger seismic and horizontal load resistance capabilities and is suitable for areas with seismic intensity above 8 degrees. As a reference, the epicenter intensity of the Wenchuan earthquake reached 11 degrees, and an 8-degree fortification means it can withstand most destructive earthquakes.

抗风：可抵抗每秒70米飓风。 轻型钢结构建筑自重轻、强度高、整体刚性好，建筑物自重仅是砖混结构的五分之一，可抵抗每秒70米的飓风。70米/秒是什么概念？超强台风“山竹”登陆时的最大风速约45米/秒，70米/秒的风速已经超过大多数台风的破坏力。

Wind resistance: can withstand hurricanes up to 70 meters per second. Lightweight steel structure buildings have a light weight, high strength, and good overall rigidity. The building's self weight is only one-fifth of that of brick and concrete structures, and it can withstand hurricanes up to 70 meters per second. What is the concept of 70 meters per second? The maximum wind speed of Typhoon Mangkhut when it made landfall was about 45 meters per second, and the wind speed of 70 meters per second exceeded the destructive power of most typhoons.

保温：100mm保温棉相当于1米砖墙。 轻钢结构采用玻纤棉作为保温隔热材料，100mm左右厚的R15保温棉热阻值可相当于1米厚的砖墙。外墙保温板还能有效避免墙体的“冷桥”现象。对于北方寒冷地区和南方炎热地区，这个保温性能直接转化为空调和采暖的能耗节省。

Insulation: 100mm insulation cotton is equivalent to a 1-meter brick wall. The light steel structure uses fiberglass cotton as insulation material, and the thermal resistance value of R15 insulation cotton with a thickness of about 100mm can be equivalent to a 1-meter-thick brick wall. External wall insulation board can effectively avoid the phenomenon of "cold bridge" in the wall. For cold regions in the north and hot regions in the south, this insulation performance directly translates into energy savings for air conditioning and heating.

隔音：墙体可达60分贝。 轻钢体系安装的窗均采用中空玻璃，隔音达40分贝以上；由轻钢龙骨、保温材料石膏板组成的墙体，隔音效果可高达60分贝。60分贝的隔音意味着隔壁大声说话基本听不见。

Sound insulation: The wall can reach up to 60 decibels. The windows installed in the light steel system are all made of insulated glass, with 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. A 60 decibel sound insulation means that you can hardly hear loud voices next door.

这些数据不是营销话术，是轻钢结构“轻而不弱”的技术支撑。选轻钢建筑时，问问厂家“抗震设防烈度多少、保温层厚度多少、隔音指标多少”，比听“我们的房子很结实”更有用

These data are not marketing jargon, they are the technical support for the "light but not weak" lightweight steel structure. When choosing light steel buildings, asking the manufacturer "what is the seismic fortification intensity, insulation layer thickness, and sound insulation index" is more useful than hearing "our house is very sturdy"
