1.What types of classic general types are included?
Sine wave (S-shaped): The waves are smooth, sinusoidal curves with no sharp corners. The wave height is typically 5-15mm, and the wave spacing is 50-100mm.
It provides even force distribution, good wind resistance, and is less susceptible to dust and water accumulation.
Trapezoidal wave (T-type): The corrugation is "trapezoidal" (flat top, vertical or slightly inclined sides), with a wave height of 10-25mm and a wave distance of 100-200mm. The load-bearing capacity is better than that of sine wave, and the overlap is more stable during installation.
Arc wave (U-shaped): The ripples are in a semi-circular shape (the bottom is an arc, with a smooth transition on both sides), with a wave height of 8-20mm and a wave distance of 80-150mm. It has smooth drainage (water is not easy to accumulate at the bottom of the arc) and is slightly more aesthetically pleasing.
2.What are the main types of efficient coverage?
Large Wave Type (High Wave, Long Spacing Type)
Structural Features: Wave height 25-40mm, wave spacing 200-300mm, and the effective coverage width of a single sheet can reach 800-1200mm (far exceeding the 500-800mm of the classic type).
Core Advantages: Large coverage area, reduced panel usage per square meter, and fast installation. The high-wave structure improves overall bending strength, making it suitable for long-span roofs (such as warehouses with spans over 10 meters).
Typical Applications: Large industrial factory roofs, logistics warehouse roofs, and rain shelters for open-air cargo yards.
Combined Corrugated Panel (Dual Corrugated/Multiple Corrugated Panels)
Structural Features: A single panel features a "main corrugation + secondary corrugation" design (e.g., main corrugation height 30mm, secondary corrugation height 10mm, with alternating corrugation spacing), balancing wide coverage with localized load-bearing capacity.
Core Advantages: The main corrugation provides overall load-bearing and drainage, while the secondary corrugation enhances panel flatness and reduces post-installation deformation. Effective coverage widths can reach 1000-1500mm.
Typical Applications: Roofs of medium-sized steel structure factories and large livestock farms (such as dairy farms and piggeries).
3.What types of special function types are there?
Interlocking Corrugation (Locked Edge Corrugation)
Structural Features: The corrugated edge design features an interlocking groove, allowing adjacent panels to be mechanically locked during installation (rather than simply overlapped). Corrugation height is 15-35mm, and the distance between the corrugations is 150-250mm.
Key Advantages: Extremely airtight (better than conventional overlaps for rain and wind protection), and strong wind-uplift resistance (suitable for areas prone to typhoons and heavy rain).
Typical Applications: Factories in coastal areas, buildings in high-altitude areas (resistant to strong winds), and storage sheds requiring waterproofing (such as grain warehouses).
Low-Density Corrugation
Structural Features: Extremely low corrugation height (3-8mm), small distance between the corrugations (30-60mm), dense corrugations, and high overall flatness.
Key Advantages: Smooth surface, suitable for wall decoration or interior partitions (not load-bearing roofing), and can be directly painted.
Typical Applications: Factory exterior wall panels, temporary building interior partitions, and equipment protection panels. Rib-Shaped Corrugation
Structural Features: Additional longitudinal ribs (narrow raised strips) are added between the corrugations, or "indentations" are designed at the top of the corrugations. The corrugation height is 15-30mm.
Core Advantages: Significantly improves the bending and flexural strength of the sheet material, making it suitable for applications requiring load bearing (such as rooftops for equipment placement and snow-covered areas).
Typical Applications: Roofs in northern snowy areas (to withstand snow loads) and factories with small equipment (such as ventilators) on the roof.
4.What is the core basis for choosing waveform?
Wave Height (H): Higher wave heights provide greater load-bearing and wind resistance (suitable for large spans and snow-covered areas); lower wave heights provide improved flatness (suitable for walls and small spaces).
Pitch (P): A larger pitch increases the effective coverage width (saving materials and increasing efficiency); a smaller pitch increases the uniformity of the panel (suitable for applications requiring high flatness).
Effective Coverage Width (B): The actual coverage width of a single panel after excluding the overlap (e.g., a 1.2-meter-wide panel may only have an effective coverage of 1 meter), which directly impacts installation efficiency and cost.
5.How to match the appropriate tile type according to the scene?
Simple temporary buildings → Choose classic trapezoidal or sine waves;
Large factories/warehouses → Choose large wave or combined wave patterns;
Coastal/snowy areas → Choose interlocking or reinforced wave patterns;
Walls/partitions → Choose low-density wave patterns.
