1. Panel Material Classification

The covering panels for warehouse walls and roofs are predominantly single-layer corrugated steel, with rock wool composite and polyurethane composite options also available. Crucially, avoid using polystyrene (foam) corrugated steel panels; they are a significant fire hazard and difficult to extinguish. Similarly, do not utilize plastic panels as a covering, as they offer inadequate wind resistance, aging resistance, and fire protection. In colder climates, composite panels provide excellent insulation. Single-layer panels are suitable for warmer regions. In inland areas with minimal wind, a 0.4mm thickness is generally sufficient. Coastal areas prone to typhoons require 0.6-0.8mm thickness to prevent panel deformation and cracking. For composite panels, the outer steel gauge should be increased based on the expected wind load, while the inner layer typically requires a gauge of 0.3-0.4mm. To enhance protection, select roofing profiles with a higher peak, and lower-profile wall panels. For those with budget flexibility, manganese-magnesium alloy panels or aluminum alloy panels are excellent choices. Alternatively, galvanized steel panels with a colored coating can offer a more economical solution.

2. Panel Color Options

Panel colors vary, each suited to different contexts: white, medium gray, dark gray, light blue, red, grass green, dark green, camouflage, silver, brown, and orange are all common. Choose a color that aligns with your preferences. Color combinations can involve a single, uniform color for the entire wall, or a patchwork of different colors. However, avoid evenly distributed color patterns. A dominant color should account for approximately 70% of the surface area, with accent colors comprising the remaining 30%. Consider using accent colors around the perimeter of the roof or at the corners. Minimize curved or flowing color transitions, as they increase construction complexity.

3. Panel Installation & Accessories

Corrugated steel installation typically includes self-tapping screws and corner trims. While we generally don’t detail self-tapping screws in renderings due to their small size, we do depict corner trims, door trims, and window trims because their color significantly impacts the visual appearance.

4. Supporting Steel Framework

When creating warehouse renderings, the supporting steel framework should also be visible. This is because interior renderings are often generated from a perspective within the building, allowing viewers to see both the exterior walls and the internal steel framework. If only an exterior rendering is required, the framework can be omitted. Panel placement must align with the actual steel framework during the design process – arbitrary placement is unacceptable. Considerations such as awnings above doorways require carefully planned support structures, with short overhangs supported directly by the framework and longer overhangs requiring suspended rods to ensure structural integrity.

5. Surrounding Environment Design

The warehouse should be surrounded by roadways on all sides. A fixed access ladder must be located at one corner, allowing for convenient roof access for maintenance purposes. However, the ladder should be positioned at least 2 meters from the ground to prevent children from climbing. Avoid planting trees directly adjacent to the warehouse. Typically, no debris should be stored around the building perimeter. Warehouse fires can often originate from external sources rather than internal causes.

6. Fire Safety Measures

A sand pit should be positioned on the left side of the warehouse entrance for storing fire-retardant sand, and a water reservoir on the right side for water. Properly designed warehouses will not have internal wiring; all electrical wiring should be external, routed through approved conduits, and brought into the building. Only switches and lights should be installed inside, minimizing extensive wiring. This approach reduces the risk of fire. The external wiring can be concealed within metal conduits made from bent sheet metal with rock wool insulation to protect the wires from the elements and temperature fluctuations. Windows are essential for ventilation and provide a means for emergency egress. Curtains can be used to shield goods from sunlight, but the primary purpose of the windows is ventilation and as an emergency escape route.
