Painted hollow steel features Technical Properties: Painted hollow steel profile has many technical features. Surface Treatment: Prior to painting, HSS may undergo various surface treatments, such as pickling, blasting, or phosphating, to enhance the adhesion of the coating and provide a protective layer against corrosion. Welding and Joining: HSS can be welded or joined using techniques like gas metal arc welding (GMAW), shielded metal arc welding (SMAW), or resistance welding. The specific method chosen depends on the HSS grade, the thickness of the sections, and the desired joint properties. Fireproofing: For applications where fire resistance is critical, HSS can be treated with fireproofing coatings or intumescent paints. These materials expand […]
