Jinhongtong Group presents the JHT-PFB-SG8, a Seismic grade 8 prefabricated steel school gymnasium building engineered for Latin America seismic zones. 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 Latin America seismic buyers worldwide.

• Earthquake Grade 8: JHT-PFB-SG8 is designed to seismic grade 8 per GB 50011, with ductile frames that absorb seismic energy in Latin America seismic.
• Rigid Frame + Bracing: Cross bracing and rigid frame action distribute lateral forces evenly through the structure.
• High-Strength Connections: Grade 10.9 bolted connections provide ductility and prevent brittle failure under cyclic loads.
• Wind Load 12 Levels: The gymnasium envelope resists 12-level typhoon winds with secure cladding fixings.
• Certified Engineering: Seismic and wind load calculations are certified by licensed structural engineers before fabrication.
• Safe Assembly Areas: Large clear spans create safe, column-free spaces for schools and community gatherings.

Typical applications include school gymnasiums, sports halls, community centers, emergency response warehouses and multi-purpose assembly buildings in active seismic zones.

For Latin American clients, the structural design follows GB 50011 seismic provisions and can be adapted to local codes, with site-specific seismic reports delivered before fabrication begins.

Jinhongtong 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.

High-strength bolt kits are batch-tested and supplied with torque specifications. All members are shot blasted and painted with epoxy systems before packing.

Certified seismic calculation reports, shop drawings and installation manuals are included. Our engineers provide remote technical support during erection, and a 10-year warranty applies.
