Product Description
Jinhongtong Group presents the JHT-PFB-SB25, a Prefabricated steel building with Sa2.5 shot blasting surface treatment for coastal Southeast Asia warehouses. Manufactured under strict ISO 9001 quality control with CE-certified processes, this prefabricated steel building combines structural reliability, rapid construction and long service life, making it a trusted choice for Southeast Asia coastal buyers worldwide.
Key Features- Sa2.5 Shot Blasting: JHT-PFB-SB25 members are shot blasted to Sa2.5 grade, removing mill scale and rust for perfect coating adhesion in Southeast Asia coastal.
- Three-Layer Paint System: Epoxy zinc-rich primer plus polyurethane topcoat delivers 120-180 um total protection.
- Salt Spray Verified: Coating systems pass 800+ hours of ASTM B117 salt spray testing for coastal environments.
- Stainless Steel Fasteners: All exposed fasteners are grade 304 stainless steel, eliminating rust streaking on facades.
- AZ150 Roofing: Galvalume roof sheets resist edge corrosion and reflect solar heat in tropical climates.
- Long Coating Life: Properly maintained, the paint system protects the structure for 15-20 years before first maintenance.

Manufacturing QualityJinhongtong operates 170 sets of advanced fabrication equipment, including large hydraulic press brakes, CNC drilling machines, large-scale shot blasting units and ultrasonic flaw detectors. Processing follows AISC 360, Eurocode 3 and EN 1090 standards, with strict raw material inspection, precision CNC cutting, professional submerged arc welding, and full visual and UT/MT non-destructive testing before delivery. This disciplined process ensures every member arrives on site with exact dimensions and flawless coating.
Packaging & Quality AssuranceCoated members are inspected with dry-film thickness gauges before packing, and damaged areas are repaired with zinc-rich paint. Members are separated with plastic spacers to prevent transit abrasion.
A corrosion maintenance manual covering inspection and touch-up intervals is provided. Coating performance is backed by mill certificates, and a 10-year structural warranty applies.
