Video Gallery: See Before You Specify
Most steel building manufacturers show you renderings. We show you the factory floor, the launch of a 748 m covered bridge, and the Antarctic station that survived a blizzard while under construction. Watch how 200,000 tonnes of annual capacity translates into projects you can verify.
Factory Tour: 200,000 T Annual Capacity, Not a Concept
Our 320,000 m² production campus in Xuzhou, Jiangsu Province, houses 12 specialized production lines, from 3,000-tonne hydraulic pressing and CNC flame cutting to shot-blasting, automatic welding, and hot-dip galvanizing baths up to 14 m in length. The videos below walk through each stage of the process that turns a Tekla model into a container-loaded shipment.
Campus Overview: From Raw Coil to Loaded Container
Aerial and ground-level walkthrough of our 320,000 m² facility. See the 3,000-tonne hydraulic press forming box-column sections, the 12 m × 3 m CNC flame-cutting table, and the sequential shot-blast, primer, and hot-dip galvanizing line that processes 200,000 tonnes annually.
CNC Cutting, Beam Assembly & Automatic Welding
Watch a 40 mm Q355B flange plate cut to a bolted-sphere node profile on a 6-axis CNC plasma table, then moved to the assembly jig where H-beam web-to-flange joints are welded by submerged-arc machines at 450 A, 32 V, with 98.5% UT-pass rate.
Hot-Dip Galvanizing: 14 m Bath, 80-µm Coating
Surface preparation through shot-blasting to Sa 2.5, fluxing, immersion in a 460 °C zinc bath for 4-6 minutes depending on section thickness, and controlled cooling. The result: an 80-µm zinc layer per ISO 1461, with 30-year corrosion protection in C3-C4 environments.
Filmed on Site, Not in a Studio
These documentaries follow projects from the first soil test to the final bolt torque check. They include the problems that actually happened: a monsoon delay on a coal shed, a -28 °C Antarctic blizzard, and the logistics of moving a 35-tonne truss segment across three provinces.
Antarctic Ross Sea Station: Building at -28 °C
The documentary follows the design and erection of China's 5th Antarctic research station on the Ross Sea coast. Key engineering challenges: C5-M corrosion environment, 60 m/s design wind speed, and a 6-month construction window dictated by ice-breaker logistics. The steel frame had to be pre-assembled in Xuzhou, disassembled for container shipment, and re-erected with no on-site welding.
Guangzhou Baiyun T3: 450,000 m² Terminal Roof
Baiyun Airport Phase III demanded a 450,000 m² terminal roof with main spans of 54 m and a total structural steel weight of 42,000 tonnes. The documentary covers the spatial grid design (bolted-sphere nodes, 300 × 300 mm grid, Ø60 × 3.5 mm tubes), the incremental launching sequence over active runways, and the 24-hour shift schedule that delivered the steel closure 11 days ahead of programme.
Xianyang Covered Bridge: 748 m, China's First Qin-Style Two-Level Steel Landscape Bridge
At 748 m, the Xianyang Covered Bridge is China's first Qin-style two-level steel pedestrian landscape bridge. The film documents the prefabrication of the box-girder deck segments in our Xuzhou shop, the transverse launching across the Wei River, and the installation of the hand-fitted Dougong-style decorative brackets that give the bridge its traditional Chinese silhouette.
Installation Time-Lapse: From First Bolt to Handover
Time-lapse sequences compress weeks of field work into minutes you can watch during a coffee break. Each film includes the date-stamped erection log, weather interruptions, and the critical path moments: first column plumb, first truss lift, roof closure, and final inspection walk.
Coal Shed Erection: 96 m Span in 47 Days
A 96 m × 210 m enclosed coal yard at Huizhou Port. The time-lapse shows the incremental assembly of a bolted-sphere space frame (grid 3 m × 3 m, Ø89 × 4 mm tubes) starting from a central scaffold tower, expanding outward in 6 m rings. Total steel: 1,850 tonnes. Erection rate: 39 tonnes per day at peak.
GAC New Energy Capacity Expansion Workshop
Original factory footage for the GAC passenger-car capacity-expansion assembly workshop. The local case study covers the 85,000 m² workshop, double-layer grid roof, hybrid bolted-and-welded sphere joints and fabrication sequence.
High-Rise Steel Frame: 4 Floors per Week
A 24-storey commercial tower with cross-shaped-to-box column transitions and composite floor slabs. The time-lapse captures the 4-floor-per-week cycle: column splice (2 hours per joint, full-penetration butt welds, 100% UT), beam installation, decking placement, and concrete pour. Fireproofing application follows 72 hours behind the steel crew.
Testimonials Filmed on Their Sites, Not in Our Office
We asked three clients if we could film them on their own projects, with no script and no coaching. The result is unfiltered feedback from people who have actually paid for and lived with our structures.
Republic of Congo Airport: "The Shipment Arrived Complete"
The project manager for the Congo airport terminal extension describes receiving 340 tonnes of pre-assembled steel in 12 open-top containers, with every bolt, gasket, and lifting lug accounted for in the packing list. "We have worked with Chinese suppliers where 15% of the bolts were missing. With Permanent, the packing list matched the container seal. That saved us three weeks."
Qatar Islamic Studies: "They Understood GCC Standards"
The consulting engineer for the Qatar Faculty of Islamic Studies complex explains why they selected a Chinese fabricator for a project with QCS 2014, BS EN 1090-2, and LEED Gold requirements. "Permanent's Qatar team had already delivered three projects in Doha. They knew the Ministry of Municipality approval process, the third-party inspection sequence, and the documentation format. That experience was worth more than a 10% price discount."
Angola Social Housing: "2,400 Units, Zero Re-work"
The construction director for Angola's national social housing programme discusses the delivery of 2,400 PEC-integrated residential units across 12 sites. "The biggest risk in a multi-site programme is dimensional drift: column centre-lines that start at 6.0 m and end at 6.1 m after 200 bays. Permanent's CNC jigs held tolerance to ±2 mm, and the bolted connections meant our local crews could assemble without welding inspectors. Zero re-work on frame alignment across all 12 sites."
