Steel Cast In Channel/Halfen Channel

Widely used in:Concrete wall curtain; Precast concrete plate; Pipeline support system; Brick structural support.

Curtain wall, high-speed rail, bridge, hospital, nuclear power plant, tunnel and so on.

Hafenchannel is a C-type embedded channel steel, which is fixed in the concrete by embedding method, and is bolted to secure the external members. The origin of the name of Halfen Trough: the name of Halfen originates from the German Halfen company, which has been consuming embedded channel steel since 1929, named "Halfen trough". Halfen has been operating in China since 2008. Due to its high brand influence in the world, in recent years, there have been many channel steel manufacturers operating "Hafen trough" as the main business, and the industry has taken "Hafen trough" as a synonym for all embedded channel steel.

Quality and characteristics of Halfenchannel:
1. Hafenchannel high load capacity, up to 32kN or 128kN/m;
2. Small margin, up to 5cm;
3. Easy to adjust;
4. No noise and dust during installation;
5. Obtained the official certification, can be used for static and dynamic bearing;
6. Halfenchannel has good anti-corrosion performance and is made of stainless steel or hot-dip galvanized steel.

Materials/Corrosion protection:
· Hot dip galvanized (fv) Havin channel steel
· Hafen channel steel of stainless steel (A4)
· Hafen channel steel of high corrosion resistance stainless steel (HCR)

Halfen embedded grooves (Halfen grooves), bolts and other fittings
In addition to good adjustability, Halfen embedded channel steel can save a lot of installation time, ensuring rapid construction and cost savings.
Halfen slots are ideal for easy and adjustable installation. The use of filler in the channel can prevent concrete from entering the channel. Harvin can be used to fix any component, such as external walls, precast concrete structures, residential construction and traffic works (such as tunnels), as well as elevators, infrastructure projects such as Bridges or crane walkways.

Cold bending and hot rolling

• Ideal connectors for easy installation and adjustment

• Suitable for installation in concrete compression and tension areas

• Hot rolled channel steel, suitable for fatigue impact loads

Fast economy
·1. Adjustable fixation
·2.bolts instead of welding
·3. The efficiency is highest when installed in rows
·4. Save cost by installing with simple tools
·5.Reduce construction time through upfront design
·6.A wide range of products to meet diverse needs
·7.easy to install; No noise, no dust and no vibration

Basic technical requirements of hot-dip galvanized Hafenchannel embedded parts:
1, C-type steel and I-steel (78*25*5) are hot-rolled manufacturing;
2, the material is Q235;
3, hot dip galvanized surface treatment, zinc layer thickness is not less than 55um

Basic technical requirements for hotdipping T-bolts.
1, the use of 45# steel, forging, quenching and tempering treatment
2. The tensile force of T-bolt and C-slot embedded parts is not less than 70KN
3, thread in line with GB196, GB197 standards
4, surface galvanized passivation treatment, galvanized thickness after centrifugal treatment is not less than 15um
The appearance of the trough embedded part effectively solves the problem of the force point of the large external curtain wall. The application of trough embedded parts in curtain wall engineering can realize the real sense of the unit construction procedure. Its advantages are balanced force, convenient installation and easy adjustment. Halfen slot T-bolt can be processed and assembled into: production line, assembly line operation workbench, office partition, screen, industrial stable fence, various frames, display shelves, shelves, mechanical dust seal protection and so on.
Another glass curtain wall Hafen groove special T-bolt, material A3, 45#,4.8 level, 6.8 level, 8.8 level. Electrogalvanizing, hot-dip galvanizing, mechanical galvanizing (powder galvanizing).

Hafen channel steel has the advantages of safety, reliability, convenience and economy, especially with the rapid development of China's subway and high-speed rail projects, the demand for Hafen channel steel is greatly increased. The high bearing capacity of the Halfen channel naturally greatly strengthens the technical requirements for the connection between T-bolt and C-channel steel. At present, the most advanced and mature process skills in this area are: radial riveting process skills.
