Catnic CG90/100 Cavity Wall Lintel 1800mm | Supreme Merchants

The Catnic CG90/100 Cavity Wall Lintel 1800mm is a standard-duty structural steel lintel designed to provide reliable support over wider openings in cavity wall construction. Engineered for masonry spans where increased length and stability are required, this lintel is suitable for residential and light commercial building applications.

Manufactured from galvanised steel with a durable powder-coated finish, the Catnic CG90/100 lintel offers excellent corrosion resistance and long-term performance. Its integrated insulation core helps reduce cold bridging across the cavity, enhancing the thermal performance of the wall system and supporting compliance with modern energy efficiency standards.

The open-back profile allows continuous inner and outer masonry leaf construction, simplifying installation while ensuring even load distribution above openings. The 1800mm length makes this lintel particularly suitable for larger apertures such as double door spans or wide window openings.

This lintel also includes a built-in damp proof course (DPC) and an integral plaster key, helping streamline on-site installation and reducing the need for additional components.
