Product Description
A Straight Column Primary Steel Frame is a standardized and cost-effective structural system featuring columns with uniform cross-sections (constant width and height), engineered for simplicity, ease of fabrication, and wide applicability. Manufactured with Q235B/Q355B high-strength steel (straight columns, I-beam beams) and 8.8/10.9-grade high-strength bolts, this product features straight columns (H-beam or box-section, size: 200×200mm to 600×300mm) with consistent cross-sections throughout their height, ensuring straightforward factory fabrication and on-site assembly. The main beams adopt I-shaped cross-sections (250×125mm to 700×300mm) with yield strength ≥235MPa (Q235B) or ≥345MPa (Q355B), and bolted or bolt-welded joints between beams and columns provide reliable force transmission, limiting vertical deflection to ≤L/500 (L=span length) and lateral displacement to ≤H/500 (H=frame height). Key features include simplified design (easy to model and fabricate), cost-effectiveness (30% lower fabrication cost than tapered columns), and high compatibility with standard components (purlins, girts, wall panels). The surface is treated with hot-dip galvanizing, epoxy paint, or black oxide coating, providing salt spray resistance ≥800 hours and adapting to indoor, outdoor, and general industrial environments. It complies with GB 50017-2017 and EN 1993 structural standards, supporting span customization (6m-24m) and column spacing (4m-10m) to meet diverse project needs. Professional services include load calculation, component size selection, on-site installation training, and quality inspection, ensuring the frame balances simplicity, reliability, and economy.
Applications
Straight Column Primary Steel Frames are versatile and practical structural solutions ideal for low-rise to mid-rise buildings, light-industrial facilities, and budget-sensitive projects. Certified by GB 50017-2017, EN 1993, and ISO 9001, they meet essential structural safety standards. Typical applications include low-rise industrial workshops (light manufacturing, assembly plants), small to medium warehouses (span 6m-18m), commercial buildings (small retail shops, office buildings), agricultural facilities (barns, small greenhouses), prefabricated buildings (modular houses, temporary structures), and residential buildings (1-5 story villas, townhouses). They are particularly suitable for projects in low-seismic zones (intensity ≤7 degrees) and areas with moderate wind loads, where complex structural designs are unnecessary. The minimum order quantity is 5 sets for standard specifications, with customized solutions available based on span size, column size, and load conditions. Competitive pricing and bulk purchase discounts (for orders over 50 sets) enhance cost-effectiveness, while short delivery times (7-15 workdays for standard orders) support fast-track construction. With a monthly supply capacity of 150 sets, the manufacturer ensures timely delivery and professional technical support. Customization options include corrosion-resistant upgrades (304 stainless steel) for humid environments, fire-resistant coating (fire resistance ≥1 hour) for commercial buildings, and lightweight design for temporary structures.
