Roof safety
Metal roofs shed snow. Decide where.
Bar and bracket snow retention systems fixed into the profile without penetrating the weathering surface.
Profile cross-section — schematic, not to scale
Overview
A metal roof sheds snow, and it does so all at once. Above an entrance, a walkway or a parked car, that is a safety problem rather than a convenience — which is why snow retention is not optional on most Finnish roofs.
Our systems clamp to the seam or fix into the profile with system brackets, so the retention load is transferred into the structure rather than into the sheet, and the weathering surface is not penetrated where it matters.
Bar count and bracket spacing follow from roof pitch, plane length and design snow load. We size the system as part of the quote.
Load goes into the structure, not into the sheet.
Bar count set against pitch, plane length and snow load.
Finished to disappear into the roof rather than sit on it.
Technical data
All VANKKA data is metric. Values are confirmed for your project at quotation and issued with the technical documentation.
Finishes
Coating choice is driven by exposure and expected service life rather than by colour. Both are confirmed with your quotation.
The volume coating. Proven, economical, widely specified.
Low gloss, low reflection, contemporary.
Built for the Nordic envelope.
Thick film, high mechanical resistance.

On-screen colours are approximations. Coated steel changes appearance with gloss level, surface texture, viewing angle and daylight. Always confirm a colour against a physical VANKKA sample before ordering.

Ordered with the profile, these come from the same coil and the same batch — so they match exactly.
