Established in 2014, Grandex Door Solutions Co., Ltd. is a premier entry door manufacturer operating from a modern 35,000 m² facility. With 16 years of industry expertise and 8 years of dedicated export experience, the company generates an annual export revenue of USD 28 million. Grounded in strong OEM and ODM trade backgrounds, our products primarily serve North America and Western Europe, supported by a network of over 1,200 supply chain partners. We cater to leading building material distributors, real estate developers, and commercial contractors. Quality is integral to our operations: supported by strict ISO 9001 certified internal testing and third-party laboratory verification, our 45-member QA team ensures rigorous quality control throughout production. Driven by an active R&D division with 85 specialized engineers, we introduced 120 new door designs last year and offer full custom solutions spanning custom dimensions, security locks, surface finishes, and decorative glass panels.
Designed for Finnish U-values, our French windows provide superior thermal insulation, critical for mitigating energy loss in Nordic winters.
We ensure all products meet EU Construction Products Regulation (CPR) and local Finnish safety standards (CE marking).
Perfect for Helsinki's modern modular construction trends and the renovation of historical estates, offering high-durability timber-aluminum composites.
Grandex leverages a "Global-Local" strategy. While our manufacturing hub produces at scale, our technical team works directly with Finnish architects to integrate "Smart Window" sensors and security lock systems. We focus on low-maintenance, high-durability surfaces specifically treated for the high UV exposure in summers and high moisture levels in winter.
