​The HULK Standard Slab Coil Insert is a general-purpose lifting and anchoring component engineered for medium-thickness precast concrete slabs. It provides dependable working loads, quick installation, and secure attachment points for handling, transport, and permanent structural connections.

​Thin Slab Coil Inserts are engineered to provide secure lifting and reliable handling for thin precast concrete panels throughout production, storage, transportation, and installation. Manufactured from high-strength steel with precision-formed coil threads, they deliver excellent load capacity and dependable performance in demanding precast applications.

​Flared Thin Slab Coil Insert is specifically developed for lifting and fixing applications in thin precast concrete components where installation space is limited. Its flared body enhances load distribution within the concrete, while the sealed end prevents concrete slurry from entering the internal thread during casting, ensuring smooth bolt engagement after curing.

​Expanded Coil Coil Inserts are engineered embedded fastening components designed to provide reliable threaded connections and effective load transfer within precast and cast-in-place concrete structures. Featuring an expanded-pitch coil section at the embedded end, the insert distributes applied loads across a larger area of surrounding concrete, helping reduce localized stress concentrations and improve anchoring stability.

Flared Loop Coil Insert is a high-performance embedded fastening component designed for secure threaded connections in precast concrete structures. Manufactured through advanced resistance welding technology, the flared loop connector is firmly welded onto the steel coil to achieve excellent strength, stability, and durability.

The Straight Loop Coil Insert is a reliable embedded fastening component designed to create secure threaded connection points in precast and concrete structures. Its simple loop configuration and efficient fabrication make it suitable for bolted connections, lifting, handling, and anchoring applications when properly engineered.

The Precast Wall Connection Wire Loop Boxis a reliable and efficient solution for connecting precast concrete wall elements. It is available in single-layer and double-layer designs, featuring single or double wire rope loops to meet different load and strength requirements.

Lifting Anchor with Plate is a precision-designed connection system designed to ensure the safe, stable, and efficient lifting of precast concrete components. Constructed from alloy steel, it provides superior load-bearing capacity and reliable anchoring force in both vertical and inclined lifting operations.

HULK Metal's Half Channel T-Bolts, with a mechanical property grade of 8.8, provide secure, high-strength connections in precast concrete and structural applications. Each bolt is crafted from high-quality carbon steel, alloy steel, or stainless steel and precision-forged to ensure dimensional accuracy and load-bearing performance.

​Connection Loop Boxes are a reliable solution for creating secure and efficient joints between precast concrete units and in-situ concrete structures. Designed with a durable steel casing,each box contains flexible wire loops that can be easily released using no-tool tear-off tape, ensuring simple and fast installation.

HULK Metal's concrete screw anchors are safe and simple to use, and can be accessed from above the fixture, providing convenience and efficiency in a variety of construction scenarios.

Our Cast-in Channels are meticulously fabricated from both hot-rolled and cold-rolled profiles, incorporating precision-pressed T-Bolts. This ensures efficient and secure anchorage in concrete structures.
