PPGL Steel Coil - Prepainted Galvanized Steel Coil for Roofing & Construction

PPGL steel coil represents a premium grade prepainted galvanized steel solution engineered for demanding construction and roofing applications. This factory-finished metal substrate combines a hot-dip galvanized steel base with a baked-on paint system, delivering exceptional durability against corrosive environments while maintaining superior aesthetic appeal. Designed for architects, contractors, and metal building manufacturers seeking cost-effective yet high-performance building materials, PPGL steel coil serves critical roles in residential roofing, commercial cladding, and industrial panel fabrication across diverse climatic conditions.

What is PPGL Steel Coil?

PPGL steel coil is a pre-finished metal product consisting of hot-dip galvanized steel substrate coated with multiple layers of paint applied through a continuous coil coating process. The galvanized base provides a zinc coating of 40-275 g/m² per ASTM A653, while the paint system typically includes a primer layer and topcoat with total thickness ranging from 15-25 micrometers per side, offering both corrosion protection and decorative finishes for architectural and construction applications.

PPGL Steel Coil Technical Specifications

Our PPGL steel coil is manufactured according to JIS G3312 and ASTM A755 standards, featuring base metal thickness from 0.14mm to 1.2mm with width options between 600mm-1,250mm. The zinc coating weight complies with Z60-Z275 classifications, providing corrosion resistance rated for C3-C4 environments per ISO 12944. The paint system achieves pencil hardness of 2H minimum and demonstrates T-bend flexibility of 0T-2T depending on coating thickness, ensuring optimal forming characteristics for roll-forming and panel fabrication processes.

Frequently Asked Questions

What is the minimum order quantity (MOQ)?

Our standard MOQ is 25 metric tons per specification, though we accommodate smaller trial orders of 10 tons for new customers evaluating material performance. Mixed container loading is available for orders combining different colors or thicknesses, with lead times adjusted based on current production schedules and your specific coating requirements.

Do you provide material test certificates?

Yes, we supply comprehensive mill test certificates (MTC 3.1 per EN 10204) documenting chemical composition, mechanical properties, coating weight, and paint system specifications. Certificates include batch-specific test results for tensile strength, yield strength, elongation percentage, and coating adhesion values, along with third-party SGS inspection reports upon request for international shipments.

What is the typical delivery time?

Standard color PPGL steel coil ships within 15-20 business days from order confirmation, while custom RAL colors require 25-30 days for paint formulation and production scheduling. Express production is available for urgent projects with 10-day lead times, subject to current factory capacity. We provide weekly production updates and coordinate shipping arrangements to optimize your project timeline.

Can you cut to custom sizes?

Our slitting capabilities accommodate custom widths from 50mm to 1,250mm with tolerance of ±2mm, while length cutting services provide sheets from 1,000mm to 6,000mm with ±5mm precision. We also offer edge trimming and protective film application to prevent handling damage during transportation and installation, ensuring your material arrives ready for immediate fabrication.
