Frequently Asked Questions (FAQ)

What are the available base materials and specifications for the color coated steel sheets?

The base materials include DX51D+Z, SGCC, and SGLCC (both Galvanized and Galvalume). The zinc coating ranges from Z60-Z275 (Galvanized) and AZ50-AZ150 (Galvalume), with customizable thicknesses from 0.3mm to 1.2mm, widths from 600mm to 1250mm, and lengths up to 12m for corrugated sheets.

What is the warranty period for the paint coatings?

We offer a 10-year warranty against fading, chalking, and red rust for PE coatings, and an extended 20-year warranty for PVDF coatings. Note that the warranty does not cover improper installation, natural disasters, or human-induced damage.

What quality standards and certifications do these products meet?

Our products can be produced according to GB/T 12754-2006, ASTM A653, and EN 10147 standards. Quality control includes raw material inspection, online tracking of coating thickness, surface visual checks, and mechanical/corrosion resistance sampling tests. Certificates such as ISO9001, SGS, and BV are available upon request.

What are the recommended overlap and fastener parameters for installation?

The recommended overlap length is ≥50mm for roofing profiles and ≥40mm for wall cladding. Fasteners should be galvanized self-drilling screws equipped with EPDM washers. To protect against thermal expansion and contraction damage, expansion joints should be installed every 6 to 8 meters.

What is the minimum order quantity (MOQ) and production lead time?

Our standard minimum order quantity (MOQ) is 5 tons (negotiable depending on requirements), and the standard production lead time is 7 to 15 days following the receipt of the deposit.

How are the steel sheets packaged and where are they shipped from?

Products are wrapped with waterproof plastic film, kraft paper, and reinforced with steel strips, and then packed securely on export-standard wooden pallets. Shipments are typically dispatched via main ports in China, including Shanghai, Ningbo, and Qingdao.
