Lintel features
Catnic - Leaders in technical innovation. Our commitment to provide the building industry with new and improved products is borne from investment in design and manufacturing technologies.
Material
The lintels are manufactured from hot-dipped galvanised steel to BS EN10142: 2000 of grade DX51D & Z275 with a black coloured polyester resin finish. The protection system complies fully with the chemical and physical test requirements outlined in Table 2 of BS 5977: PART 2: 1983 for lintels effectively having their own built-in Damp Proof Course (DPC).
Duplex Corrosion Protection System
Many Catnic lintels employ not just one but two methods of protection against corrosive attack: The unique, sophisticated Duplex Corrosion Protection system. This double method of protection gives Catnic lintels inherent benefits over those offered by other manufacturers using the more traditional pre or post-galvanised steel techniques.Both these processes rely on just a simple coating of zinc to provide cathodic protection. The zinc protects the steel but is itself liable to rust with aqueous alkaline solutions leaching from the building fabric and therefore corrode. The famous black coating makes Catnic lintels instantly recognisable and provides an effective barrier against moisture or chemical attack leached from the mortar and masonry.
Built-in Damp Proof Course
Many Catnic lintels offer a unique profile shape that combine with the Duplex coating to eliminate the need for a separate DPC ultimately saving time and cost.
Integral Plaster Key
Many Catnic lintels come complete with an integral plaster key that avoid the hazards of working with a mesh key.
Continuous Insulation
Many Catnic lintels are supplied with CFC & HCFC free insulation maximising their thermal efficiency and compliance with Part L.
