Care: Protect the lintel from damage during handling and installation. Inspect the lintel for any damage before installation. The galvanised steel construction requires minimal maintenance, however, any damage to the protective coating should be addressed to prevent corrosion. Ensure proper drainage to prevent water accumulation.
