PPGI APPLICATIONS

Built for Roofing, Cladding & Roll Forming

PPGI combines a color-coated surface with a zinc-coated steel substrate, making it suitable for formed building products that require consistent appearance, corrosion protection, and reliable processing performance.

CUSTOM PROCESSING

PPGI Coils Prepared for Your Production Line

Processing requirements can be coordinated before production to reduce additional handling and help the material match downstream equipment.

FACTORY & PRODUCTION

Built for Stable Production & Order Delivery

PPGI orders are managed from specification confirmation through color coating, inspection, packaging, and loading to support consistent supply for international projects and distributors.

  • 3 Color Coating Lines
  • 2 Galvalume Production Lines
  • Advanced Manufacturing Equipment
  • Large Inventory Support
QUALITY CONTROL

PPGL Quality Checked at Critical Stages

Base Metal & Dimensions

Steel grade, thickness, width, and dimensional tolerances are checked against the confirmed order.

Metallic & Paint Coating

Metallic coating and paint-coating requirements are checked according to the agreed specification and applicable inspection method.

Color & Surface

Color reference, gloss, surface appearance, coating consistency, and visible defects are inspected.

Forming & Adhesion

Relevant coating adhesion and forming-performance checks can be conducted according to the confirmed specification.

Coil & Packaging Condition

Coil condition, identification, packaging, and loading protection are checked before shipment.

EXPORT PACKAGING

Built for Long-Distance Ocean Shipping

PPGI coils require protection against moisture, impact, edge damage, movement, and painted-surface contamination during storage, handling, and ocean transportation.

  • 01

    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.

  • 02

    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.

  • 03

    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.

  • 04

    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.

  • 05

    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.

  • 06

    Professional Container Loading

    Steel coils are wrapped with waterproof paper and protective steel sheets to minimize moisture exposure during transportation.

Faqs

Frequently Asked Questions

View More FAQs
What is PPGI steel coil?
PPGI is prepainted galvanized steel. It uses a zinc-coated steel substrate with an additional paint system applied to the surface. It is commonly used for roofing, wall cladding, sandwich panels, and roll-formed building components.
What is the difference between PPGI and PPGL?
PPGI uses a galvanized zinc-coated substrate, while PPGL uses a galvalume substrate with a 55% aluminum-zinc alloy coating. The appropriate material depends on the exposure environment, forming requirements, project specification, and budget.
Which paint system should I choose?
PE, SMP, HDP, and PVDF are available for different requirements. Selection should consider UV exposure, weather conditions, expected color performance, forming needs, and project budget.
Can you match a specific color?
RAL colors and custom color matching can be discussed. The final color should be confirmed using an agreed color reference or approved sample before production.
Can PPGI coils be supplied for roll forming?
Yes. Steel grade, thickness, width, coating adhesion, coil dimensions, and surface-protection requirements should be matched to the downstream roll-forming equipment and profile.
What information is required for a quotation?
Please provide the steel grade or standard, thickness, width, zinc coating requirement, paint system, color, gloss, coil weight, coil ID, quantity, destination port, processing needs, and packaging requirements.
Can you provide samples before bulk production?
Sample availability and color confirmation arrangements can be discussed according to the required material, color, coating system, and project schedule.
What documents can be supplied with the order?
Available documents and inspection records depend on the confirmed order and customer requirements. Please specify the required certificates or reports before quotation.
