Product Details

Duojia’s concrete wedge anchors, with yellow zinc plating, are manufactured in our advanced Yongnian District plant, leveraging decades of expertise to produce fasteners that prioritize secure expansion and rust protection for concrete beam applications. The carbon steel design (grades 4.8–8.8) includes a cone wedge that pulls upward during tightening, locking firmly into the substrate without requiring special tools beyond a wrench. Our expansive 5,000+ square meter facility uses precision stamping, threading, and forming processes to achieve a 500-ton monthly output, maintaining high consistency. To install, drill a matching hole (e.g., 10mm for M10), clean thoroughly, insert the anchor with nut and washer loose, and torque the nut to expand the wedge—prevent overtightening to avoid base damage. Suited for fastening panels or units in buildings, they undergo detailed grade and plating inspections with AAA certification. We support custom lengths or coatings, complemented by reliable after-sales including replacements within three weeks for defects. Exported globally, these anchors embody Duojia’s commitment to sustainable, high-quality production, delivering a yellow zinc solution for durable, vibration-tolerant fixings in construction sites, warehouses, and structural reinforcements where precision and endurance are paramount.

Product Parameters

Product Features

Concrete wedge anchors from Duojia excel with their yellow zinc plating on carbon steel, providing enhanced rust resistance and a bright finish that suits aesthetic requirements in visible installations, outperforming basic galvanized options in moderately corrosive atmospheres. The wedge expansion mechanism, paired with a nut and washer, offers immediate, permanent locking with high pull-out strength across grades, ideal for dynamic loads in beams or walls. Certified through comprehensive tensile and coating tests under AAA protocols, they allow for tailored configurations like extended rods for deeper embeds. Duojia’s efficient manufacturing ensures competitive wholesale pricing and prompt delivery, accommodating urgent construction timelines. These anchors’ cone design minimizes drilling depth while maximizing grip, integrating corrosion protection with simple mechanics to deliver a versatile fastener that boosts installation speed and reliability, setting a standard for applications where secure, low-maintenance anchoring is vital without complex equipment.

Product Applications

Concrete wedge anchors are crucial for construction projects, fastening rebar or brackets to concrete beams with their expansion hold for structural reinforcements in buildings and bridges. In warehouses, they secure safety barriers or shelving to floors, ensuring stability in high-traffic storage areas. For commercial setups, they’re used to mount HVAC or electrical systems to walls, benefiting from yellow zinc in indoor environments. Duojia supplies to international markets like Canada, Mexico, and Thailand, with straightforward installation: drill (matching diameter, e.g., 10mm for M10), clean, insert, and tighten nut for wedge activation—avoid overtightening. They’re also effective in renovations for attaching fixtures in retail spaces. This anchor’s heavy-duty capability supports general industry and heavy tasks, facilitating permanent, vibration-resistant fixings that improve safety and functionality in diverse concrete-based applications.
