Q355B Steel for Desulfurization DeNOx Systems, Corrosion Resistant
prodnct deecrlption
The desulfurization and denitrification steel structure system made of Q355B low-alloy high-strength steel is specially engineered to provide high rigidity load-bearing support for environmental protection equipment. Modular design facilitates equipment installation and maintenance, reducing on-site welding workload. We 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. The material requires protective processes such as heavy-duty anti-corrosion coating or hot-dip galvanizing to withstand harsh chemical environments in desulfurization and denitrification processes.
