To realize the vision of future construction featuring new technologies, new materials, cost reduction and higher efficiency, the deep integration of S690/S960 ultra-high-strength steel structures with BIM, MiC and DfMA technologies has become the most advanced one-stop full-life-cycle efficient construction solution adopted by top international engineering projects.

Through Peakkong Special Steel’s one-stop precise factory prefabrication, 90% of complex processes are completed in the factory, realizing zero welding and ultra-fast assembly on site. Details of this efficient construction system are as follows:

100% interference and collision simulation: Before construction starts, BIM (Building Information Modeling) is used for 3D modeling and assembly simulation of complex structures (pipe trusses, cross columns and box structure joints), solving component collision problems in the digital stage in advance.

CAM linked automatic cutting: BIM data is directly imported into the factory’s processing system to drive high-precision laser cutting machines and mechanical grooving equipment (accurate 3mm grooving). The geometric tolerance of 8–50mm high-strength steel components is controlled to millimeter level, eliminating secondary on-site repairs caused by dimensional errors.

DfMA (Design for Manufacture and Assembly): Breaking conventional construction thinking, components are designed to facilitate factory fabrication and fast on-site hoisting from the very beginning. Complex steel trusses and BH built-up beams are mass-produced in the controlled factory environment in strict accordance with EN 1011 temperature control requirements (100–150°C preheating, 250°C post-weld hydrogen removal and slow cooling, Sa2.5 shot blasting instead of pickling to prevent hydrogen embrittlement), ensuring products meet the highest safety standards of EN 1090-2 EXC3/EXC4.

MiC (Modular Integrated Construction): High-strength steel structures, fire wall panels, mechanical and electrical pipelines, and even interior finishes are integrated into independent three-dimensional Pod modules directly in Peakkong Special Steel’s factory.

Ultra-fast assembly with zero on-site welding: After modules are delivered to site, all splices adopt 100% friction-type connections with Grade 10.9 or higher strength bolts (slip resistance coefficient of faying surface μ ≥ 0.5). No overhead on-site welding or outdoor wind and rain shelters are needed; only pre-tightening and final tightening with torque wrenches are required, improving construction speed by 3 to 5 times.

• 50% reduction in material consumption: Ultra-high strength reduces component cross-sections, with plate thickness decreased by 30% to 50%, greatly lowering total steel procurement weight.
• Sharp reduction in welding and anti-corrosion costs: Thinner plates lead to geometric reduction of welding groove area, cutting welding wire consumption and labor hours. Smaller component surface area also reduces consumption of shot blasting, hot-dip galvanizing and anti-corrosion paint.
• Fixed logistics and hoisting costs: Greatly reduced self-weight cuts transportation trips by half. Smaller-tonnage cranes can be used on site, lowering site rental and operation costs.

This technical system of high-strength steel + BIM + one-stop prefabrication is widely applied to future infrastructure projects with extreme requirements for construction speed, structural strength and span:

• Bridges: Large-span steel box girders and steel truss girders, fabricated into large segments in the factory, transported by water and hoisted into position on site in one operation.
• High-rise and large public buildings: Mega cross columns, box columns and variable-section BH main beams, serving as the framework of modern high-rise buildings and MiC modular structures.
• Port facilities and port machinery: Container gantry cranes, ship unloader booms and stockyard structures. S960’s extreme weight reduction expands the working radius and maximum lifting capacity of machinery.
• Airports and subway stations: Super-large-span pipe truss roofs and heavy-load transfer trusses for underground stations, realizing column-free large open spaces.
• Intelligent logistics warehouses: Ultra-high large-span portal frames integrated with dense storage racks, doubling space utilization rate.
• Towers (wind power and high-rise structures): High-power wind turbine towers and ultra-high communication towers. High-strength steel effectively resists extreme wind loads and dynamic load fatigue.
