Finished Space Frame Member Painting Process

The space frame member painting process at Xuzhou Shengjian uses shot blast cleaning to Sa2.5, zinc-rich epoxy primer, and polyurethane topcoat — 180-240 microns total DFT checked on 100% of members. ISO 12944 C3/C4 corrosion category protection for 15-25 year service life. Contact us for a free coating specification recommendation.

Technical Advantages

The painting and anti-corrosion coating process at Xuzhou Shengjian is a critical quality step that protects every space frame member for its full design service life. Our 50,000m² factory includes a dedicated paint shop with shot blast preparation, zinc-rich primer application, and polyurethane topcoat finishing — all applied and inspected to ISO 12944 corrosion category standards. Key features: • Shot blast cleaning to Sa2.5 standard before any coating application • Zinc-rich epoxy primer 60-80 microns dry film thickness • Intermediate epoxy coat for added barrier protection • Polyurethane topcoat in any specified RAL color — 60 microns DFT • Dry film thickness checked on 100% of members with calibrated DFT gauge • Total system typically 180-240 microns DFT — C3 or C4 corrosion category Our coating systems are engineered to protect space frames for 15-25 years in industrial, coastal, and tropical environments without repainting.
