This Q355B steel structure system is engineered for logistics storage parks requiring large unobstructed floor space and high load capacity. The large-span design supports high-bay racking systems up to 12m in height, optimizing vertical storage density for distribution operations. The enhanced structural rigidity reduces building sway during high wind or seismic events, protecting stored inventory and racking systems from damage.
For e-commerce fulfillment operations, the column-free interior space supports automated sorting equipment, conveyor systems, and flexible picking zone layouts. The structure accommodates multiple loading dock positions along the building perimeter, supporting simultaneous loading and unloading for high-throughput operations. The floor load design supports heavy forklift traffic and stacked inventory storage common in e-commerce fulfillment workflows.
The anti-seismic steel structure provides stable storage for industrial raw materials, finished goods, and heavy equipment in manufacturing logistics parks. The corrosion-resistant treatment on steel components withstands exposure to industrial environments and variable weather conditions. The open interior layout supports flexible reconfiguration of storage zones as operational requirements change over time.

The structure includes a complete bracing system consisting of column cross bracing, horizontal tie rods, and knee braces at beam-column connections. This system distributes seismic loads across the entire frame, reducing concentrated stress at connection points during seismic events. Bracing components are sized according to local seismic design codes to meet project-specific intensity requirements.
Q355B low-alloy high-strength structural steel provides a minimum yield strength of 355MPa, offering higher load capacity and better ductility than Q235B steel. The material properties allow for larger span designs with smaller member sections, increasing usable interior space while maintaining structural integrity. The steel meets national standard GB/T 1591 requirements for low-alloy structural steel used in building construction.
All beam-column connections use rigid welded joints with high-strength bolted connections for on-site assembly. The connection design follows plastic hinge formation principles, allowing controlled energy dissipation during seismic events without sudden structural failure. All connection points undergo finite element analysis during the design phase to verify load transfer capacity under extreme load conditions.
The structure can be engineered to support overhead crane systems with lifting capacities ranging from 5t to 50t. Crane beam brackets are integrated into the main frame during production, with load calculations completed to verify structural capacity for crane operation loads and dynamic impact factors. This supports heavy material handling operations within the warehouse facility.
Multiple door options are available including rolling shutter doors, sliding doors, and pedestrian access doors, with sizes customized to match logistics vehicle dimensions. Loading dock positions can be pre-configured with dock leveler supports and bumper installation points. The front reserved door opening design allows for flexible placement of loading bays along any building elevation.
The structure supports installation of fire sprinkler systems, smoke ventilation systems, and natural ventilation equipment. Roof ventilators and FRP daylight panels can be integrated into the roof system to reduce daytime lighting energy consumption and improve natural air circulation. Electrical and plumbing penetrations are pre-located during the design phase to reduce on-site modification work.
The standard design meets Grade 9 seismic intensity requirements, with customization available for higher seismic zones based on local building code specifications. All structural calculations are completed according to international building seismic design standards, with third-party verification available for projects requiring formal engineering approval.
The single-span design reaches up to 60m without intermediate columns, providing completely unobstructed floor space for logistics operations. Multi-span continuous designs can achieve unlimited building width by connecting multiple single-span units with shared columns, supporting logistics park facilities of any required size.
Yes, the main frame can be designed to support single-girder or double-girder overhead crane systems with capacities from 5t to 50t. Crane runway beams and bracing reinforcements are integrated into the structural design during the engineering phase, with deflection limits set according to crane operation requirements.
All main steel components receive hot-dip galvanized treatment with a minimum coating thickness of 85μm, providing corrosion protection for 20+ years in normal outdoor environments. Routine maintenance includes inspection of bolt tightness every 2-3 years, touch-up of any damaged paint or coating areas, and cleaning of gutter systems to prevent water blockage. No major structural maintenance is required under normal usage conditions.
