What materials are included in a steel structure warehouse building?
10/30/2025
As the material system of a steel structure warehouse building, it plays a critical role. We will break down its material composition into four parts. 1. Main Structural Framework of warehouse Typically, steel structure warehouse require large, flexible spaces. The most appropriate structural form is selected based on specific requirements. The most common structural forms and their corresponding materials are generally categorized as follows: Portal Structure Primary Materials: H-shaped steel, I-beams. Connection Method: Bolted connections. Characteristics: This form offers convenient fabrication, a high degree of customizability, and rapid installation. It balances strength with durability and has lower requirements for concrete foundations. It is the primary choice for industrial warehouse buildings. Grid (Space Frame) Structure Primary Materials: Steel tubes and solid spherical nodes. Connection Method: Steel tubes are connected to the nodes via bolts. Characteristics: This system provides high overall structural strength. It can be assembled on the ground and then hoisted as a complete unit into position by cranes. With spans capable of exceeding 100 meters without the need for interior columns, it is exceptionally well-suited for production warehouse with high spatial requirements. Truss Structure Primary Materials: Steel tubes or rectangular hollow sections, welded together. Characteristics: The key advantage is excellent structural durability. As these trusses require no on-site welding, they are hoisted into position as complete units. This makes them particularly suitable for regions with heavy snow loads, such as cold climates. 2. Secondary Structural System of Warehouse The secondary structure generally includes the purlin system and the bracing system of the steel structure warehouse building. Purlin System: Materials: C-shaped or Z-shaped steel sections are typically used for wall and roof purlins. Large-Span Solutions: For purlins with longer spans, H-shaped steel or trussed purlins may be employed. Integration: The purlins are tied together with steel tubes and round steel tie rods, ensuring the integrity and stability of the entire structural frame. Bracing System: Materials: Steel tubes are commonly used as sag rods or horizontal braces between steel columns. Function: This system connects all the columns, enhancing the overall rigidity and strength of the building to resist lateral forces like wind. 3. Warehouse Envelope System The building envelope of a steel structure warehouse is critically important, as it must combine aesthetics with performance characteristics like wind resistance, corrosion resistance, and protection against solar radiation. Commonly used materials include Color Steel Sheets and Sandwich Panels. Color Steel Sheets: The thickness and material quality of these sheets are paramount. Premature rusting and leakage within 3-5 years are often directly attributed to the use of inferior-quality materials. Sandwich Panels: These panels are selected based on their durability, fire resistance, and thermal insulation properties. Common core materials include: Rockwool Sandwich(Stone Wool) Polyurethane Sandwich (PU) Glass Wool Sandwich panel For cleanrooms, sandwich panels are typically used for both wall cladding and ceiling panels. For areas with extreme hot or cold climates, PU Sandwich panels are an excellent choice, offering a balance of strength and environmental performance (high insulation value). For high fire safety requirements, rockwool sandwich panels are the optimal solution. They boast an A1-grade fire rating (non-combustible) and provide excellent thermal insulation. Doors & Windows: Doors: The selection is based on the size of the logistics access points. Common options include Shutter Doors and Sliding Doors. In areas prone to high winds, wind-resistant roll-up doors are essential. Windows: As the primary source of natural light, windows should also offer thermal insulation. Frames are typically made from Aluminum or PVC. Glazing options range from single-pane to superior double-pane (insulated) glass. 4. Bolts and Accessories The installation of a steel structure warehouse involves connecting prefabricated structural components with bolts. The connection between steel columns and beams typically requires Grade 10.9S high-strength bolts, whose strength exceeds that of the main structural members themselves. The installation of the secondary structure utilizes galvanized Grade 8.8S bolts. Cladding sheets are fixed using galvanized or stainless steel self-drilling screws or blind rivets, which must balance strength with corrosion and water resistance. At sheet overlaps or eave locations, sealant and waterproof closure strips must be used to ensure weathertightness.
