4.2x30 screws - seam roof panels. Sheets for so-called standing seams are one of the oldest technologies used in construction. Now we can offer a modern solution in the traditional shape of standing seam sheets known for years.

• The panels are manufactured for any length depending on the client's needs.
• The panels are connected with the latch without bending the seam.
• Each panel has ready mounting holes for easy attachment to the structure.
• The use of longitudinal profiling on panels is intended to reduce the possible surface waving due to thermal expansion of the material.
• Machine-cut locks (optional for PD 510P-S, PD 510T-S and PD 510F-S panels) allow mounting on the starting strip.
