SHEILD ROCK 62x41 mm Plain Strut Channels are the ideal choice for structural and mechanical projects dealing with heavy loads and long spans. The additional height (62 mm) provides a higher moment of inertia, reducing deflection and increasing the channel's capacity to bear large weights without the need for closely spaced additional supports. These channels feature a smooth, unslotted surface that grants maximum strength, making them ideal for building support structures for heavy equipment, major HVAC systems, and high-density cable trays.
