Corrosion classes, ISO 9223
Lumasol classes each site from its address.
- C4 coastal band, indicative
- Countries supplied, inland generally C1 to C3
- Ballito, KwaZulu-Natal
- C4
- Roof clamp spacing for anodised aluminium is reduced by 5%.
- C5
- Stainless components and fasteners must be cleaned and treated against corrosion every five years.

Design basis
From the Lumasol installation manuals. Each kit page gives the limits for that system.
Kit families- Wind
- Wind regions A to D: basic wind speeds of 32, 36, 40 and 44 m/s at a 50-year recurrence.
- Codes
- SANS 10160-3:2019 for the non-penetrative tilt calculations; AS/NZS 1170.2:2021 for the tile system.
- Terrain
- Each manual states the terrain categories it was assessed for, with spacing factors outside them.
- Height
- Guidance up to 20 m installation height.Above 20 m, a project-specific engineering certificate is required.
- Roof slope
- 0° to 30°.
- Interface spacing
- Up to 1.5 m where each system's stated conditions are met, and reduced outside them.The conditions for each kit are on its product page and in its manual.
Warranty questions
What does a claim need?
Tell Lumasol within 15 days of finding the defect. Have the purchaser's details, the product codes, the purchase invoice, the warranty certificate, the installation date and address, and a description of the defect with photographs and any maintenance records.
What maintenance keeps the warranty valid?
An annual check of the torque on all fasteners, regular cleaning to remove soil and contaminants with cleaners made for aluminium, and immediate treatment of any damage to galvanising. Harsh chemicals and abrasive materials must not be used.
What does the warranty not cover?
Among other exclusions: installation that does not follow the installation manual or is not done by qualified personnel, non-genuine parts or accessories, roofs or foundations whose load capacity has not been assured, transport damage, and surface oxidation that does not affect structural integrity. The full list is in the warranty document.
Who holds the warranty?
The original purchaser of the product, and only for products bought from Lumasol as shown by an original Lumasol invoice.
Register within 30 days of purchase
The warranty is active once the original purchaser registers it. Have the Lumasol invoice to hand.
