Paint coatings for structural steelwork are usually spray applied. The paint is atomised into fine droplets and projected onto the surface to be protected where the droplets join together to form a continuous film. The atomisation can be accomplished in a number of ways.
Steel structure painting parameter
| Parameter | Description | Typical Value | Notes |
| Surface Preparation | Cleaned surface (sandblasting/shot blasting) | Sa 2.5 (ISO 8501-1) | Removes rust and impurities |
| Paint Type | Coating material based on environment | Epoxy, Polyurethane, Zinc-Rich Primer | Enhances corrosion resistance |
| Coating Thickness | Uniform application for durability | 100-150 microns | Adjust based on environment |
| Curing Time | Time allowed for drying/curing | 4-8 hours per coat | Depends on paint type and conditions |
| Attribute | Description |
| Surface Roughness | Enhanced texture from sandblasting for optimal paint adhesion and durability. |
| Corrosion Resistance | Protective coating that prevents rust and withstands harsh environmental conditions. |
| Adhesion Strength | Strong bond between paint and surface, reducing risk of peeling and flaking over time. |
| Coating Thickness | Uniform paint layer, typically 100-150 microns, providing consistent coverage and protection. |
Steel structure welding
Steel is used for ship hulls, offshore platforms, and docks because of its strength and durability in demanding environments.
2. Uniform and Seamless Joints
3. Resistance to Environmental and Mechanical Stress
Applications of Steel Structure Welding
Given these features, steel structure welding is widely used in the construction of buildings, bridges, industrial facilities, shipbuilding, oil and gas infrastructure, and heavy equipment. The combination of strength, flexibility, and efficiency makes welded steel structures a core choice for modern engineering solutions.
Located close to major highways, it is only 2 hours' drive from Qingdao. Our engineering department is staffed by experts in the design and manufacture of steel structures .Our know-how in mechanical welding and our compliance with industrial standards guarantee maximum quality control.
