SHEILD ROCK Double Strut Channels (82x41 mm, Back to Back) represent the pinnacle of strength in metal support systems. This model is manufactured by joining two 41x41 mm channels together back-to-back, resulting in a channel with a total depth of 82 mm that provides immense structural rigidity and superior resistance to deflection under heavy loads. These channels are the ideal solution for building support structures in power plants, factories, and large pipe bridges, providing total safety and exceptional stability in the most demanding construction conditions.
