The curtain wall frame system is an extensional bench riveting structure, which utilizes the excellent static value of fine steel profiles to the extreme. The visible integrity plane is onlyof the 38mm, itprofile not only shows the excellent vision of the system, but also guarantees the lowest UF value of the system and satisfies the structural stress of the whole system. Light interior depth surface minimum size is only 50mm, the system is not limited by any glass thickness and can be matched with any open system, is a comprehensive innovation fine steel profile glass partition system.
