In the modern construction era, the Knock-down (KD) door frame has revolutionized how developers and contractors approach interior and exterior installations. Unlike traditional welded frames that are bulky and expensive to ship, KD frames are designed for modularity. Globally, the demand for custom knock-down door frame factories has surged, particularly in regions like North America, Australia, and the Middle East, where high-density residential projects and commercial high-rises dominate the urban landscape.
Industry reports indicate that the door frame market is shifting toward materials that offer both durability and aesthetic flexibility. From Hollow Metal Steel Frames for industrial safety to WPC (Wood Plastic Composite) for moisture-prone areas like hospitals and hotels, the variety of "knock-down" solutions is expanding to meet localized building codes and architectural trends.
Our flagship commercial-grade hollow metal door frames utilize a precision-engineered mitered corner design. This allows for a "snap-together" installation that maintains the structural integrity of a welded frame while offering the convenience of field assembly. Perfect for hotel retrofits and new hospital wings where timing is critical.
View Technical Specifications →The transition toward Industry 4.0 has reached the door frame sector. Leading Chinese factories, like Foshan Green Earth Wood Co., Ltd., are integrating AI-driven precision cutting and automated finishing lines. This ensures that every mitered joint and screw hole in a knock-down frame is accurate within 0.1mm, eliminating the common frustration of on-site misalignment.
Local procurement needs have also evolved. In North America, the trend is moving toward "Pre-primed MDF" and "Finger-jointed Pine" frames that allow for rapid painting. In contrast, the Australian market often demands high-density timber or termite-resistant WPC frames. Our ability to customize these frames at the factory level allows us to serve these diverse global markets effectively.
Foshan Green Earth Wood Co., Ltd. is a "grey-hair" wood moulding and door frame supplier from China, bringing over 12 years of specialized expertise to the international stage. With a core focus on the Australian and North American markets, we have cultivated a reputation for reliability and technical excellence.

Engineered for longevity, our WPC (Wood Plastic Composite) door jambs combine the natural aesthetic of wood with the durability of polymer. These knock-down components are 100% waterproof, making them the ideal choice for tropical climates or high-moisture interior environments like bathrooms and kitchens.
Explore Color Options →Sourcing from a specialized Chinese factory like Green Earth Wood offers more than just cost savings. It provides access to a sophisticated supply chain that can pivot between materials—such as MDF, Solid Pine, and Galvanized Steel—within the same production hub. For a procurement officer in the US or Australia, this means a "one-stop-shop" experience for all door casing and frame requirements.
Furthermore, the "Knock-down" design is particularly suited for the Amazon/E-commerce and DIY retail sectors. Modern consumers look for products that are easy to transport in a personal vehicle and simple to assemble with basic tools. Our custom KD frames are designed with this "Local Application" in mind, featuring pre-slotted grooves and universal hardware compatibility.
Our product portfolio is built to serve the entire building envelope. Whether it is the crown moulding that finishes a luxury ceiling or the fire-rated steel frame that protects an emergency exit, our precision is unwavering.
Specializing in White Primed MDF and Finger Jointed Pine. Our door jambs and baseboards are treated with high-quality gesso and primer, ready for a final topcoat on-site. Ideal for suburban housing developments.
Providing UL and FM certificated hollow metal frames. These KD frames are designed for high-traffic areas, offering fire resistance ratings from 20 to 90 minutes. Essential for malls, schools, and hospitals.
With a monthly export of 20 containers each to North America and Australia, we have mastered the nuances of international shipping standards and regional humidity variations that can affect wood products. This expertise ensures your frames arrive straight, dry, and ready for installation.
