The workshop project for Luoyang Aohai Refractory Materials Co., Ltd. is a key expansion project designed to support refractory materials production and processing. The facility adopts a portal steel frame structure, offering large spans, lightweight design, and high space utilization efficiency, making it highly suitable for modern industrial production.
The foundation adopts a compacted cement-soil composite base with independent footings, ensuring reliable load-bearing capacity and overall structural stability. The building is designed in accordance with national standards for Class II industrial buildings, balancing durability, seismic safety, and fire resistance, with an intended service life of 50 years.
Steel Structure Configuration
Steel columns: ~310.35 tons
Steel beams and crane beams: ~257.63 tons
Secondary members: ~46.97 tons
Roof purlins: ~167.92 tons
Corrosion & Fire Protection
Non-galvanized members coated with two layers of red oxide primer; dry film thickness: 150μm (outdoor), 125μm (indoor).
Steel columns: fire resistance ≥ 2.5 hours, with thick fireproof coating up to 41.5mm.
Steel beams: fire resistance ≥ 1.5 hours, with coating thickness up to 19mm.
Different areas adopt varied coating thickness to ensure comprehensive fire safety.
Structural Advantages
Portal steel frame structure ensures fast construction and cost efficiency.
Structural design accommodates crane installation and allows future expansion.
As of now, the workshop construction is progressing steadily, with the following completed works:
Roof skylight and wall cladding installation completed
Interior wall panels installation completed
Rainwater pipes 80% completed
Canopy installation completed
Roof rectification completed
Parapet inner panels installation completed
Flashing and edge finishing completed
The overall structure has been formed, with interior finishing and detail works currently underway.
Upon completion, this workshop will provide a highly efficient and modern production facility for Luoyang Aohai Refractory Materials Co., Ltd. The application of steel structure not only shortens the construction period but also significantly improves safety, fire resistance, and durability. The project will greatly enhance the client’s production capacity and operational efficiency, laying a solid foundation for long-term development.
At the same time, the successful execution of this project further demonstrates our company’s strong capabilities in large-span steel structure design, steel fabrication, and fire & corrosion protection technologies, strengthening our leadership position in the industrial steel building sector.
