The Duojia White Zinc Plated (WZP) Steel Drop-in Anchor is a heavy-duty, internally threaded expansion anchor engineered for secure and reliable fastening in solid concrete. Manufactured from high-grade carbon steel and finished with a durable white zinc plating, this anchor provides an excellent combination of strength and corrosion resistance for a wide range of building and industrial applications. It is designed to be set flush with the concrete surface, creating a permanent, high-strength threaded socket for attaching fixtures, equipment, and structural components. As a fundamental fastener for construction professionals, industrial maintenance teams, and general contractors, the Duojia WZP Drop-in Anchor ensures a simple, fast, and robust anchoring solution you can depend on.
The WZP Drop-in Anchor features a cylindrical body with four pre-cut expansion slots and a knurled exterior. This knurling is a critical design element that significantly increases friction against the wall of the drilled hole, preventing the anchor from spinning during installation. Internally, the anchor houses a solid expander plug at its base. The installation mechanism is straightforward and effective: after inserting the anchor into a clean, pre-drilled hole, a dedicated setting tool is used to strike the plug. This action drives the plug up into the tapered section of the anchor, forcing the four segments to expand outwards and create a secure, 360-degree frictional lock within the concrete. The entire anchor is coated with a White Zinc Plating (WZP) via an electro-galvanization process, which provides a protective barrier against rust and corrosion in indoor and dry environments. The internal threads are precision-machined to accept standard metric bolts and threaded rods, offering versatile and convenient fixture attachment.

This drop-in anchor is characterized by several features designed for optimal strength and ease of use. Its Robust Carbon Steel Construction ensures high load-bearing capacity, making it suitable for heavy-duty applications that demand strength and reliability. The Protective White Zinc Plating offers effective corrosion resistance for indoor and mild environmental conditions, while also providing a clean, professional appearance. The anchor’s High-Performance Expansion Design, featuring a knurled body and a four-way expansion mechanism, creates an exceptionally strong frictional hold, delivering excellent pull-out resistance. The Simple and Efficient Installation process (drill, clean, insert, and set) is fast and straightforward, reducing on-site labor time and ensuring consistent results. Lastly, the Flush-Mount Finish is a key advantage, leaving a clean, unobstructed surface and allowing for easy fixture removal or replacement without damaging the anchor or the concrete.
The WZP Steel Drop-in Anchor is a fundamental component in modern construction and industrial projects. In Building and Construction, it is the industry standard for suspending threaded rods from concrete ceilings to support MEP (Mechanical, Electrical, and Plumbing) systems, including cable trays, HVAC ductwork, fire sprinkler pipes, and lighting fixtures. In Industrial Maintenance and Plant Operations, these anchors are used to securely fasten machinery, conveyor systems, safety barriers, and heavy equipment to concrete floors. For Commercial Fit-outs, they are ideal for installing heavy-duty shelving, pallet racking, and structural supports. Their versatility also extends to general-purpose applications, such as securing handrails, signage, and brackets to any solid concrete or masonry surface where a strong, permanent threaded point is required.
