Description

Product Description

An Asymmetrical Primary Steel Frame is a customized structural system designed for irregular architectural layouts (e.g., L-shaped, U-shaped, or free-form buildings), integrating asymmetric load distribution, spatial flexibility, and structural stability. Manufactured with Q355B/Q460 high-strength steel (beams, columns) and Q355B connection plates, this product features non-uniform span lengths, column heights, or frame configurations, optimized via finite element analysis (FEA) to balance asymmetric forces (uneven wind, seismic, or vertical loads). The main beams and columns adopt variable cross-sections (beams: 300×150mm-900×400mm; columns: 250×250mm-700×400mm) with yield strength ≥345MPa, ensuring lateral stiffness ≥1.0×10⁵ kN/m and vertical deflection ≤L/500 (L=maximum span). Key features include rigid bolt-welded joints to resist torsional forces, reinforced corner nodes to prevent stress concentration, and factory prefabrication rate ≥90% (dimension error ≤±0.8mm) to ensure precision for irregular components. The surface is treated with hot-dip galvanizing, fluorocarbon coating, or weathering steel finish, providing salt spray resistance ≥1200 hours. It complies with GB 50017-2017 and AISC 360 standards, supporting full customization based on architectural drawings, load conditions, and seismic requirements. Professional services include asymmetric load simulation, torsional stability analysis, BIM-based design integration, and on-site installation supervision.

Applications

Asymmetrical Primary Steel Frames are versatile solutions for irregular and design-driven buildings, where traditional symmetric frames cannot adapt to architectural needs. Certified by GB 50017-2017, AISC 360, and ISO 9001, they meet strict structural standards. Typical applications include commercial complexes (L-shaped shopping malls, irregular office towers), public buildings (museums, theaters, exhibition centers with free-form designs), residential buildings (luxury villas, urban lofts with unique layouts), and urban landmarks (gateway structures, pavilion buildings). They are particularly essential for projects with asymmetric floor plans, sloped roofs, or attached wings, where balanced force distribution is critical for stability. The minimum order quantity is 1 set (customized per project), with full tailoring based on architectural layout and load conditions. Competitive project-based pricing and flexible delivery terms (20-45 workdays) support design-driven construction schedules, while a monthly supply capacity of 40 project sets ensures timely delivery. Customization options include corrosion-resistant upgrades (316L stainless steel), fire-resistant coating (≥1.5 hours) for public buildings, and weathering steel for architectural rust-patina effects.
