The SKAN HOLZ snow load extension consists of additional rafters that you mount between the existing roof rafters. This reduces the rafter spacing of the carport and increases the overall load-bearing capacity. The number and size of the rafters varies depending on the carport.
The snow load increase raises the snow load of the carport to 2.0 kN/m².
This snow load increase contains 10 additional rafters and is suitable for the following models:
- Spreewald carport 585 x 893 cm
- Green impregnated
Please note:
The snow load increase cannot be retrofitted to the carports. Please check the snow load limit required in your residential area before assembly.
Construction
The construction is made of impregnated softwood. Spruce and pine wood, which is not technically-dried, acquires its greenish color from metal salts released by the impregnating agent. They protect wood against fungus and insect infestations, but do not contain UV protection. Impregnation gives wood higher residual moisture. Subsequent drying can lead to release of resin, twisting and formation of drying cracks, which pose no static disadvantage and rather reflect the natural materials used.
Colour treatment
The wooden parts in this kit have been treated at the factory with a water-based preservative. This means the kit can be assembled straight away upon delivery. To ensure the long-term preservation of the wooden surface, it is recommended that the wood be treated further after a sufficient drying and weathering period of approximately 2 to 3 sunny months.
Before painting, the surface should be lightly sanded and cleaned. It is then recommended to apply two coats of a wood preservative suitable for outdoor use. Products with UV protection can help to reduce the visual ageing of the wood caused by weathering. Please follow the application instructions provided by the respective manufacturer.
Regular maintenance and timely re-treatment help to keep the surface in good condition over the long term. The required maintenance intervals depend on the location, exposure to the elements and the coating system used.
