Endwall Primary Steel Frame Terminal Support For Industrial Buildings And Warehouses

Product Description
An Endwall Primary Steel Frame is a specialized structural system designed as the terminal support for industrial buildings, warehouses, or large-span structures, integrating closure, load-bearing, and weather-resistance functions. Manufactured with Q355B/Q460 high-strength steel (beams, columns, bracing) and Q235B connection plates, this product features a portal or rigid-frame design (span 10m-30m) that closes the end of the main building, supporting vertical loads (roof dead load, snow load) and lateral forces (wind, seismic action). The main beams and columns adopt I-shaped or box-section profiles (beams: 300×150mm-700×300mm; columns: 250×250mm-500×300mm) with yield strength ≥345MPa, while diagonal bracing (angle steel or circular pipe) enhances lateral stability, limiting displacement ≤H/600 (H=frame height). Key features include integrated openings for doors (overhead crane doors, personnel doors) and windows, weatherproof sealing (EPDM rubber gaskets) to prevent water infiltration, and factory prefabrication rate ≥92% (dimension error ≤±1mm) to ensure alignment with the main building. The surface is treated with hot-dip galvanizing or epoxy paint, providing salt spray resistance ≥1000 hours. It complies with GB 50017-2017 and AISC 360 standards, supporting customization of span (10m-30m), door/window sizes, and load conditions. Professional services include opening layout optimization, wind load calculation, on-site installation supervision, and weatherproof performance testing.

Applications
Endwall Primary Steel Frames are essential terminal support solutions for industrial and large-span buildings, ensuring structural closure and weather protection. Certified by GB 50017-2017, AISC 360, and ISO 9001, they meet strict structural and functional standards. Typical applications include industrial workshops (end closures for manufacturing plants), warehouses and logistics centers (terminal support for storage facilities), agricultural buildings (endwalls for greenhouses, barns), and public buildings (stadiums, exhibition halls with end closures). They are particularly suitable for buildings requiring large overhead doors (e.g., crane access) or weather-tight end closures (e.g., cold storage warehouses). The minimum order quantity is 1 set (customized per project), with full tailoring based on main building span, opening requirements, and environmental conditions. Competitive project-based pricing and flexible delivery terms (15-30 workdays) support building construction schedules, while a monthly supply capacity of 80 project sets ensures timely delivery. Customization options include corrosion-resistant upgrades (316L stainless steel) for coastal environments, fire-resistant coating (≥1.5 hours) for industrial facilities, and insulated panels for energy-efficient closures.
