Overview

Corrugation Processing for Project-Ready Roofing Sheets

Steel roofing sheet corrugation converts coated steel coils into profiled sheets according to the buyer’s roofing design and installation requirements. Before processing, the material type, coating, paint system or surface finish, thickness, coil width, profile drawing, effective cover width, sheet length, dimensional tolerance, surface protection, bundle size, and packing method are reviewed as one complete specification.The service is applicable to PPGI, PPGL, galvanized steel, and galvalume steel. Material properties—including coating condition, paint surface, thickness, hardness, and forming requirements—are considered when confirming the corrugation plan and finished profile.Material supply and corrugation processing can be arranged in the same order, allowing roofing sheets to arrive in the required profile and length for construction projects, local distribution, or further fabrication.

Export Packaging & Shipping

Five-Layer Protection for Steel Coil Shipments

Each steel coil is packed through a five-step protection process to reduce moisture exposure, edge damage, surface scratches, and movement during handling and international transportation.

  • Paper Edge Protection

    Paper edge protectors are applied around both sides of the coil to cushion the edges and reduce direct contact during the subsequent wrapping process.

  • Kraft Paper & Plastic Film Wrapping

    The coil is wrapped with kraft paper and plastic film to help protect the steel surface from moisture, dust, and contamination during storage and transportation.

  • Steel Sheet Outer Wrapping

    An external steel sheet layer is wrapped around the coil body to provide additional protection against impact, scratches, and mechanical damage during handling.

  • Side Plates & Steel Edge Protectors

    Steel side plates and reinforced edge protectors are installed on both ends of the coil to protect the coil faces, inner edges, and outer edges from deformation and impact.

  • Steel Strapping & Secure Fastening

    Steel straps and fastening seals are applied around the completed package to hold all protective layers firmly in place during lifting, loading, and transportation.
