Rv - round holes staggered at 60°
The same round holes, only set out on a triangular 60° grid. More holes fit that way, so this reaches the largest open area - up to 63%.
- We perforate in-house, in Kaunas We adjust the hole size and pitch to your design.
- You can work out the open area yourself From the formula in the table - the hole and the pitch.
- Coated like the roof Polyurethane, PMG or unpainted - galvanised and aluzinc.

Coatings and warranties
Warranty length and colour choice depend on the coating, not the steel. Colour on screen is always approximate - we will send a sample before you order.
Coating shade can vary slightly between raw-material batches. If you are adding to an existing order or need an exact shade - tell us when you order.

Frequently asked questions
When should you choose the 60° layout?
When you need the largest possible open area - a triangular grid fits more holes into the same area than straight rows. Rv 10-12 reaches 63%, which straight rows cannot match. In exchange the sheet stays softer, so long spans need thicker steel.
What do W and P mean?
W is the hole size, P the distance between the centres of adjacent holes. The product designation is made up of those two numbers: Rg 6-12, for example, means 6 mm holes every 12 mm. The open area is calculated from the same figures.
What is open area and why does it matter?
It is the share of hole area in the total sheet area, as a percentage. It determines how much air, light and sound get through - and how much metal is left, and therefore how stiff the sheet is. The greater the open area, the lighter the sheet, but also the softer.
Are other size combinations possible?
Yes. The table lists the most common production combinations, but we can adjust the hole size and pitch to the project. Send us what you need and we will confirm whether that combination is made.
