Case Study: Export of 3003 Alloy High-Gloss Aluminum Sheets for Canadian Construction Applications
Views: 4 Author: Site Editor Publish Time: 2026-01-12 Origin: Site
Project Overview
In September 2025, a 20-foot container of 3003 aluminum alloy sheets was exported from China to Canada, tailored for architectural applications including roofing systems and gutter downpipes. The shipment featured 0.96mm-thick sheets with double-sided high-gloss white coatings, meeting the stringent requirements of Canadian building codes and sustainable construction standards. This case details the product customization, compliance verification, and on-site application value of the project.
