## About

GrandEx Inc. is an end-to-end building materials sourcing and supply partner for construction companies across the United States. We help developers, contractors, builders, and distributors source high-quality products directly from manufacturers in China for residential and commercial projects.

Our team manages the entire supply chain, including manufacturer selection, product customisation, quality control, international shipping, customs clearance, warehousing, and delivery to the project site. This gives our clients a single point of responsibility throughout the procurement process and helps reduce sourcing complexity, avoid costly delays, and keep materials aligned with project specifications.

We supply windows, doors, façade systems, railings, staircases, cabinetry, millwork, flooring, wall panels, tiles, pergolas, and custom building components.
