The use of Q355NH fire-resistant weathering steel can eliminate or reduce the coating, which greatly saves maintenance costs; Q355NH steel has good thickness and can be thinned, saving more than 30% of comprehensive cost. Moreover, the fire resistance and weather resistance are also permanent and self-healing, that is, the weather resistance and fire resistance of the Q355NH steel sheet can be unchanged whether after finishing or welding, or after surface rubbing or fire in use. This is not possible with ordinary steel and additional protective layers, so the benefits of Q355NH steel plate are difficult to estimate.
