Our Cast in Channel system is engineered for secure and efficient fastening in precast concrete construction. It is designed with precision to meet international standards and to provide safe working loads for diverse applications. Each channel is manufactured with quality raw materials, advanced production technology, and strict inspections, ensuring higher reliability. This versatile solution is widely used in structural connections, façade fixing, and heavy load anchoring systems.
A Cast in Channel, often referred to as a HALFEN Channel, is a reliable precast concrete fastening system that allows simple and safe connections without drilling or welding. It is composed of a steel channel with anchors fixed to its back, cast into concrete during pouring. Once cured, it provides an embedded track for T-bolts, enabling quick, adjustable, and secure connections. This system minimizes the risk of cracking, reduces installation time, and increases overall structural safety.
Compared to traditional fastening methods, Cast in Channel provides a clean solution, as the filler or tape prevents concrete ingress. It is suitable for high-load applications, façade systems, elevators, mechanical equipment supports, and industrial projects. Its modular design makes it widely accepted in modern construction, providing engineers with flexibility, safety, and cost efficiency. This makes it a preferred choice for bulk buyers and contractors worldwide.
It consists of three parts: Channel, Pin Anchor, and Filler or Tape. These components are connected by riveting or welding to create a stable fastening system.
The Channel is the main component, manufactured from hot-rolled or cold-rolled steel. At the bottom of the channel, holes are provided to allow riveted or welded connections with the pin anchors. Depending on the forming process, there are two types:
Produced by bending, it features inward-curved slots along both sides. These slots act as gripping points for the T-bolts, ensuring a secure hold. Cold-rolled channels are precise, lightweight, and suitable for medium-load applications.
Produced through hot extrusion, it has inward-protruding slots on both sides. These integral slots provide stronger gripping points for T-bolts, making hot-rolled channels ideal for heavy-duty applications.
The channel is the visible component after installation, serving as the interface for adjustable fastening. Its design ensures smooth installation, higher load capacity, and durability under demanding conditions.
The Pin Anchor transfers load from the channel into the concrete. One end connects to the channel by welding or riveting, while the other end extends into the concrete with a raised tip. This creates strong resistance, ensuring structural safety and stability under dynamic and static loads.
The Filler or Tape is inserted inside the channel before casting. Its role is to keep concrete from entering the channel cavity during pouring. Once removed, the channel remains clean and ready for T-bolt installation. This ensures fast, accurate installation and prevents costly rework at the jobsite.
Cast in Channel is manufactured from stainless steel or high-performance alloy steel, offering superior corrosion resistance and mechanical strength for different environments.
Alloy steel channels are usually treated with electro-galvanizing or hot-dip galvanizing for long-term rust protection, while stainless steel options can remain untreated due to their inherent corrosion resistance.
When using a Cast in Channel, insert the T-bolt into the slot and rotate it to engage securely. Ensure the load direction follows the design specification to prevent structural stress or damage to the precast concrete block.
The Cast in Channel serves as the embedded track, carrying the load and allowing flexible positioning of T-bolts. It is essential for creating adjustable, safe, and time-saving fastening solutions in precast concrete construction projects.
T Bolts are specially designed to fit into the channel’s slots. They provide a quick, adjustable, and strong fastening point. Once tightened, they lock into the channel, ensuring stability and resistance against sliding or rotation under load.
Our Cast in Channel is CE and ISO9001 certified, ensuring compliance with international quality and safety standards.
The Cast in Channel system functions by transferring load through the channel and anchors directly into the concrete, providing a secure, embedded fastening path. The filler keeps the channel cavity clear, and after curing, T-bolts can be inserted for immediate use.
Safe Working Load (SWL) must always meet usage requirements.
Installation must comply with international and project-specific standards.
Ensure correct bolt tightening torque and load direction.
Cast in Channel is widely applied in precast concrete construction, curtain wall installation, elevator shaft rails, tunnel systems, and heavy equipment supports. It is especially suitable for large-scale engineering projects that require flexible, safe, and cost-efficient fastening solutions.

We begin by understanding customer requirements such as specifications, surface treatment, delivery time, and project usage. This enables us to provide tailored production solutions that ensure higher efficiency and quality for every Cast in Channel order.
We source high-quality raw materials from reliable suppliers. Every steel channel undergoes strict dimensional and mechanical testing before production to ensure consistency. This guarantees that the HALFEN Channel meets international safety standards and supports long-term structural reliability.
Each pin anchor is forged under strict control to ensure excellent strength and consistency. Forged pins provide reliable resistance when embedded in concrete, helping transfer loads safely to the structure.
Pin anchors are riveted or welded to the channels using automated equipment. This creates a solid connection between the components, ensuring that the Cast in Channel performs reliably under demanding loads.
Every component is inspected before further processing. Dimensional checks, hardness tests, and tensile verification are carried out to confirm that the Cast in Channel system meets specified tolerances and safety standards.
Depending on requirements, channels are electro-galvanized, hot-dip galvanized, or produced in stainless steel. These treatments enhance corrosion resistance, extending the service life of the HALFEN Channel in different environments.
Finished products undergo final testing, including tensile, shear, and bending resistance checks. This guarantees that each Cast in Channel complies with CE and ISO9001 certifications before shipment.
High-quality fillers or tapes are inserted into the channel cavity to prevent concrete ingress during pouring. This step ensures the channel is clean and ready for fast, accurate installation on site.
We use durable, customizable packaging to protect channels during shipment. With an in-house logistics team, we ensure timely, safe, and efficient delivery of bulk orders, minimizing delays and damage.
Our professional after-sales team provides ongoing technical consultation, quality assurance, freight tracking, and problem-solving support. We aim to give clients an easier and more reliable purchasing experience for every Cast in Channel project.
