TARC Single Lock Standing Seam
The taut and regular appearance of this profile emphasises the seam. It has a broader effect than the double-lock system, giving large surface areas a dynamic, striking appearance. Sharp lines, depth and shading make it especially suitable for cladding, and the visible areas of steep roofs.
