|---|---|---|---|---|
| Profile Design | Smooth S-Wave / Sinusoidal | Angular Trapezoidal Ribs | Deep Inverted Box Flutes | Stepped Traditional Tile Pattern |
| Water Drainage Capacity | Moderate. Smooth flow, best for medium to steep slopes (>10–15°). | High. Deep channels clear heavy rainfall quickly without overflow. | Profile-dependent. Deep flutes & square ribs handle heavy tropical rain & low pitches (>5°). | Standard. Requires steeper slope (>15–20°) to help reduce transverse water ponding. |
| Load Bearing Strength | Basic / Low. Requires closer purlin spacing (800–1000mm); prone to flexing. | High. Strong structural rib design allows wider purlin spacing (1200–1500mm). | Very High. Deep box rib provides exceptional span strength & high wind/snow load resistance. | Moderate. Stepped structure provides rigidity, but purlin distance is strictly fixed by step pitch. |
| Typical Application | Agricultural sheds, temporary hoarding, light roofing, side cladding. | Industrial warehouses, commercial roofs, steel structure workshops. | Heavy industrial plants, high-rainfall regions (Africa/S. America), mining sheds. | Residential villas, gazebos, heritage-style buildings, resort roofs. |

Buyer Concern & FAQ
Which metal roofing substrates and profiles are available?
Available options can include GI, GL, PPGI, PPGL, printed metal, and prepainted aluminum in corrugated, trapezoidal, IBR, and step-tile profiles, subject to the selected product and order specification.
How should I choose a roofing substrate and coating system?
Selection depends on the project environment, roof design, substrate grade, metallic coating, paint system, forming requirements, appearance, maintenance plan, and applicable specification.
How do corrugated, trapezoidal, IBR, and step-tile profiles differ?
The profiles differ in rib geometry, effective cover width, appearance, and drainage layout. Allowable span, load, drainage, and wind performance must be confirmed from the selected material, profile, support spacing, roof slope, fasteners, installation, and engineering design.
Are custom sheet lengths and protective film available?
Custom lengths and protective-film options may be available. Suitable length and film depend on the profile, surface finish, handling method, bundle dimensions, container plan, destination, and confirmed order requirements.
How are metal roofing sheets packed for shipment?
Packaging is selected according to the material, profile, sheet dimensions, surface finish, handling method, and shipment requirements and may include protective wrapping, edge protection, supports, steel strapping, and secured loading.
