ZSJH
Designed for strength, stability, and efficient installation, primary steel frames are widely used in industrial workshops, warehouses, logistics centers, factories, commercial buildings, agricultural buildings, and pre-engineered steel buildings.
ZSJH Steel provides customized primary steel frame fabrication according to project drawings, structural requirements, building dimensions, loading conditions, and local design standards. From engineering detailing and steel fabrication to quality inspection, export packaging, and delivery, we provide reliable support for international steel construction projects.
A typical primary steel frame system includes:
H-shaped steel columns
Welded or hot-rolled steel beams
Steel roof rafters
Rigid portal frames
Base plates
End plates
Stiffener plates
Connection plates
High-strength bolt connections
Customized structural steel components
Primary steel frames are designed to safely transfer roof, wind, snow, and other structural loads to the building foundation.
Steel members can be fabricated according to customer drawings, project specifications, span, height, column spacing, and loading requirements.
Prefabricated steel components are processed and drilled in the factory, helping reduce on-site fabrication and improve erection efficiency.
Steel portal frames provide flexible large-span structural solutions with fewer internal columns, creating more usable interior space.
Bolted and welded connections are manufactured with strict dimensional control to ensure accurate assembly on site.
Available surface treatments include shot blasting, painting, zinc-rich coating, and hot-dip galvanizing according to project requirements.
