25 years of manufacturing experience. Over 20 years serving the North American market. That focus: being the extrusion partner North American window manufacturers build their business around.
Founded in 2001 in Foshan, China — one of the world's leading manufacturing hubs for building materials — Weihui was built from the ground up as a vinyl extrusion manufacturer, not a trading company or distributor. From day one, our focus was on producing high-performance vinyl (UPVC) extrusions built to exacting standards.
We entered the North American market over 20 years ago, and it's been a core part of our business ever since. Over that time, we've developed a deep understanding of what American window manufacturers need: profiles that meet AAMA specifications, consistent quality across production runs, and a partner they can actually count on.
Today, Weihui Plastic Profile, Inc. operates as our North American entity, based in Oakland, California — giving our US customers a local point of contact who is reachable in their time zone, fluent in the industry, and accountable.
Foshan Manufacturing Facility
Shishan Industrial Park, Nanhai District
Foshan, Guangdong, China
Our structure gives you the cost advantages of a direct factory relationship with the communication and accountability of a domestic partner.
Our production facility in Shishan Industrial Park, Nanhai District, Foshan is where everything starts. With 20+ extrusion lines, in-house tooling capability, and a quality management system certified under AAMA 109, it's built to produce at the consistency and scale North American manufacturers require. At least twice a year, unannounced third-party inspectors walk the floor — that's not a courtesy, it's a condition of our AAMA certification.
Our Oakland, CA office is your direct line into the company — not a customer service layer, but a US-based team that understands your production environment, your compliance requirements, and what it takes to run a window fabrication floor. Order questions, sample requests, technical support, commercial discussions — all handled here, in your time zone, without an overseas relay.
20+ Years in the NA Market
AAMA-compliant profiles for American window manufacturers
Not every Chinese extruder knows the difference between a European tilt-turn profile and an American single-hung system. We do. We've been producing profiles specifically for the North American market for over 20 years — and we've pursued AAMA certification precisely because we know it matters to US window manufacturers and their customers.
Our profiles are designed to the specifications and performance expectations of the US window industry — not adapted from European lines. When you work with us, you're getting profiles built for your market from the start.
