QH Plus Fire-Resistant Steel Structural Solution

22/06/2023

Steel structure is always applied as a crucial and irreplaceable element in most large-scale construction projects. Nowadays, the construction and utilization of steel structures in building not only require the ability to bear loads but also demand excellent fire resistance and thermal insulation. According to the QCVN 06:2021/BXD regulations, the minimum fire resistance requirement for structural components of a building is the EI standard for fire resistance: EI120. To ensure compliance with the current fire safety regulations, QH Plus Corporation has introduced the QH Plus fire-resistant steel structural solution, which offers outstanding fire resistance and thermal insulation capabilities.

Introduction of the QH Plus Fire-Resistant Steel Structural Solution

QH Plus fire-resistant steel structural solution is a breakthrough approach that addresses the inadequate fire resistance of conventional steel structural systems. Most conventional steel structural systems begin to exhibit instability when the surrounding temperature reaches 550 degrees Celsius. However, tests conducted on the QH Plus fire-resistant steel structural solution show a superior fire resistance capability at temperatures exceeding 1000 degrees Celsius.

On October 31, 2021, the Institute of Building Science and Technology (IBST) conducted fire test experiments on samples of the QH Plus fire-resistant steel structural solution. The results demonstrated that the QH Plus solution easily meets the EI120 fire resistance standard. Moreover, after being subjected to a temperature of 1053 degrees Celsius for 70 minutes, the sample’s temperature only reached 540 degrees Celsius, highlighting the effective fire resistance and thermal insulation of the product. The entire test was conducted in accordance with the ISO 834-10:2014 standard.
