Product Description
Q355B Steel Desulfurization DeNOx Corrosion Resistant
prodnct deecrlption
The desulfurization and denitrification steel structure system made of Q355B low-alloy high-strength steel is specially designed to provide high rigidity load-bearing support for environmental protection equipment. The material needs to be equipped with protective processes such as heavy-duty anti-corrosion coating/hot-dip galvanizing, which can adapt to the harsh chemical environment in desulfurization and denitrification processes. Modular design facilitates equipment installation and maintenance, reducing on-site welding workload. Provide customized anti-corrosion and structural design solutions based on environmental protection requirements in different regions. The product has passed ISO 14001 environmental management system certification and complies with global environmental standards.
