C-channel CT70H50/2NMC 864520

Robust structural support – C-channel CT70H50/2NMC

This steel C-channel is a key element of load-bearing structures, especially vertical support columns for freestanding structures. Made of S350GD steel and coated with one of the anti-corrosion coatings – Magnelis®, MagiZinc® or PosMAC – it provides exceptional durability and resistance to external factors. A sheet thickness of 3.0 mm guarantees strength even under heavy loads.

Construction and assembly

The CT70H50/2NMC C-channel is distinguished by dense perforation, which significantly facilitates the assembly of structures in difficult terrain conditions. It allows for leveling ground irregularities and enables mounting with a slight angle of inclination. The use of enlarged and densified perforation, adapted to BDF...H profiles, allows for precise adjustment of the panel angle to the ground. The change in the shape of the holes from "bean-shaped" to rectangular improves the locking of SGKFM10x20PV lock washers (with a mushroom head), which translates into the stability and safety of the entire structure. Additionally, it is possible to order a solid C-channel with perforation only in the screw connection points – this solution optimizes the cost and weight of the element when full perforation is not required.

Advantages for professionals and end-users:

• Strength and durability: S350GD steel combined with Magnelis®, MagiZinc® or PosMAC coatings provides long-lasting protection against corrosion and mechanical damage.
• Easy assembly: Dense perforation facilitates adaptation to uneven terrain and precise adjustment of the panel angle.
• Safety: Improved locking of SGKFM10x20PV lock washers increases the stability of the entire structure.
• Flexibility: The possibility of ordering a solid C-channel with perforation only in the screw connection points allows for cost and weight optimization.
• Versatility: Ideal for building freestanding load-bearing structures, such as photovoltaic or wind systems.

Technical data includes: material - steel, height - 50 mm, width - 70 mm and surface protection marked as Other.

Remember to use dedicated SGKFM10x20PV screws during assembly to ensure proper operation and safety of the entire structure.
