Catnic CN50C double leaf lintels are designed to carry the two separate leaves of a 215mm fair face wall. External solid wall lintels are resistant to corrosion without requiring any additional protection and provide optimum durability and longevity. The steel lintel is galvanised, then powder coated and has a duplex corrosion protection system that ensures optimum durability and longevity. It has an integral plaster key with staggered slots to improve its efficiency and prevent heat loss. Post-galvanisation, no on-site painting or maintenance is required. Catnic steel lintels are particularly suited to schools, hospitals or particularly aggressive environments. Due to supply shortages, we may supply a Birtley Lintel direct alternative to a Catnic. We will contact you once the order is placed to confirm the brand that will be supplied. Alternatively, please get in touch by phone or live chat before ordering if a specific brand is supplied.
