Prefabricated Airport Steel Structure

Custom prefabricated airport steel structure from EIHE China factory bridges 80-meter to 150-meter column-free spans using Q355B/Q420B circular space pipe trusses, welded box girders, and cast-steel spherical joints. Aviation terminals and wide-body aircraft hangars require vast unobstructed halls so passenger check-in islands, baggage carousels, and wingspan maintenance bays operate without interior pillars.

The roof framework combines seamless steel tubes with cast-steel spherical nodes or bolted ball joints, transferring roof loads down through bifurcated tree columns, slanted box pillars, or concrete-filled steel tubes. Over the roof, we install standing-seam aluminum-magnesium-manganese metal sheets with acoustic insulation and siphonic drainage. Every weld undergoes ultrasonic and magnetic particle testing, followed by marine-grade fluorocarbon paint that withstands 160 km/h coastal gales and Grade 8 earthquakes.

Large-Span Spatial Grid Truss Roof & Heavy Steel Columns Erected by EIHE at Qingdao Jiaozhou 4F International Airport

CNC Pipe Profiling & Heavy Aviation Spatial Grid Fabrication

Multi-Axis Pipe Intersections & Total Station Checks: Curved airport canopies require exact tubular branch profiling. In our Qingdao facility, multi-axis plasma cutting machines bevel complex saddle joints automatically, followed by 3D laser coordinate measurements on factory jigs before parts leave for the shipping dock.

National-Level Aviation Experience: As shown during roof completion at Qingdao Jiaozhou 4F International Airport, our 500-member production team delivers major aviation hubs under tight schedule constraints.

Container Packing & On-Site Block Lifting for 80m+ Airport Trusses

Shipping Long Roof Trusses in Standard Ocean Containers: For a prefabricated airport steel structure, our design team divides 80m-120m spatial pipe trusses into 11.5m to 11.8m modular sections with precision bolt sleeves that slide into 40HQ or 40OT open-top shipping containers.

Ground-Level Block Assembly & Hydraulic Hoisting: On site, ironworkers connect the pipe pieces into broad roof sections upon temporary floor jigs, add access catwalks at ground level, and lift the finished roof panels into place using mobile cranes or strand jacks.

Yantai Penglai International Airport Terminal Wave-Curved Space Pipe Truss Roof Structure by EIHE

Verified Aviation & Transit Hub Cases

We fabricated and erected the large-span spatial steel hub framework for Qingdao Jiaozhou 4F International Airport, the wave-curved terminal roof trusses for Yantai Penglai International Airport, and the spatial pipe truss roofs for Weihai Nanhai and Rushan South High-Speed Railway Stations.

FAQ

Q1: What is your minimum order size and average fabrication timeframe for aviation canopies?

A: Our minimum scope for a prefabricated airport steel structure is 50 tons or 800 square meters. Structural detailing in Tekla takes twelve to fifteen days, and fabrication runs between thirty-five and sixty days based on truss geometry and total tonnage.

Q2: How do you safeguard coastal terminal framing against salt air degradation?

A: We clean all tubular members to Sa 2.5 purity, apply an eighty-micron zinc-rich primer, an intermediate epoxy barrier, and a seventy-micron fluorocarbon top layer, offering fifty years of marine atmospheric defense.

Q3: How much ground space must remain clear beside the terminal during erection?

A: We recommend keeping a 25m to 35m wide flat apron beside the building footprint for crane setups and ground-level truss pre-assembly. Our staff supplies a detailed lifting zone diagram.

Q4: What port do you ship from, and what trade terms do you support?

A: Components are fabricated in Qingdao, China and loaded at Qingdao Port under FOB or CIF conditions. We accept 30% wire deposits and 70% before container dispatch, or letters of credit.
