All HL-products are subject to continuous factory inspections. Products with test symbols are taken a regular official monitoring and correspond to ÖNORM.The weldability of our PE-drains with all PE-pipe-product lines on the market is certificated by 'Österreichisches Kunststoffinstitut'.
Material acc. DIN EN1561 EN-GJL-200 is grey cast iron with lamellar graphite. Parts, which are made of this material, are delivered with black coating, which serves only as transport protection. Due to the natural features of this material, superficial corrosion may happen, which does not affect function and stability of these parts.
Note on processing: In combination with liquid coatings, multi-component floor coatings (reaction resins, industrial floors based on PU and epoxy), it cannot be ruled out that the contact with chemicals may lead to an increased tendency to corrosion. Appropriate caution in processing is recommended in these applications!
