Steel structure warehouse without rust treatment

Steel warehouse environment shock. Steel structure is not easy to rust, because the steel warehouse after welding, in order to prevent the stacking, transportation and installation process, no longer rust, and lay the foundation for further coating, welding components to be completed after the pretreatment and spraying "Primer" powered by. Component surface rust quality requirements to achieve Sa2.0 ~ Sa2.5 or more. According to the environmental media in which the component is located, choose the anti-rust primer. Light steel structure Primer is alkyd class, it can be epoxy zinc-rich class. In the installation site as needed and then brushing topcoat or fire retardant coating. Light steel structure is mainly H-shaped solid beam-column structure, which surface treatment and coating technology is relatively simple, but also easy to achieve mechanized assembly-line. Surface treatment using shot blasting process, roller-type or hanging feed. Painting is generally manual, combined with hanging shot blasting, but also semi-mechanized assembly line operations.
