Fire Rated Primary Steel Frame Easy Install For Fire Critical Buildings Industrial Facilities

Product Description
A Fire-Rated Primary Steel Frame is a high-safety structural system engineered to maintain load-bearing capacity under fire conditions (fire resistance ≥1.5-3 hours), integrating structural performance and fire protection. Manufactured with Q355B/Q460 high-strength steel (beams, columns) and intumescent fireproof coating (dry film ≥1.5mm), this product features a two-layer protection design: the base steel (yield strength ≥345MPa) provides inherent load-bearing capacity, while the intumescent coating expands to 10-15x its thickness at ≥300℃, forming a dense carbonized layer that insulates steel from high temperatures. The main beams and columns adopt box-section or H-beam profiles (beams: 300×150mm-800×300mm; columns: 250×250mm-600×300mm) with fireproof 封堵 material (ceramic fiber) at connections to prevent flame penetration. Key features include fire resistance certified by GB 50016, BS 476, and UL 263, maintaining ≥80% load-bearing capacity at 600℃. The surface is pre-treated with epoxy primer before fireproof coating, ensuring adhesion ≥1.5MPa and weather resistance (no cracking after 1000 hours of artificial aging). Factory prefabrication rate ≥90% ensures coating uniformity, with dimension error ≤±1mm. It complies with GB 50017-2017 and AISC 360 standards, supporting customization of fire resistance duration (1.5-3 hours), span (10m-30m), and frame configuration. Professional services include fire resistance testing, on-site coating inspection, and long-term maintenance guidance.

Applications
Fire-Rated Primary Steel Frames are essential for fire-critical buildings and industrial facilities, ensuring structural stability during fires. Certified by GB 50016, BS 476, and ISO 9001, they meet strict fire safety standards. Typical applications include public buildings (shopping malls, theaters, hospitals), high-rise residential and office buildings, industrial facilities (chemical plants, oil refineries, data centers), and infrastructure (subway stations, airport terminals). They are particularly suitable for buildings with large occupant loads, flammable materials, or critical functions (e.g., data centers, emergency rooms) where fire resistance directly impacts safety and business continuity. The minimum order quantity is 1 set (customized per project), with full tailoring based on fire resistance requirements, span, and load conditions. Competitive project-based pricing and flexible delivery terms (20-40 workdays) support fire-critical construction schedules, while a monthly supply capacity of 50 project sets ensures timely delivery. Customization options include environmentally friendly low-VOC fireproof coatings, corrosion-resistant upgrades (316L stainless steel), and enhanced fire resistance (≥3 hours) for high-risk industrial areas.
