The Keystone Steel Lintel Heavy Duty HD/K-90 1800mm is a high-strength structural support solution designed for cavity wall construction with cavity widths between 90mm and 105mm. Manufactured from durable pre-galvanised steel, this heavy-duty lintel provides reliable support above external doors, windows, and other structural openings where increased load-bearing capacity is required.

Designed for use in residential and commercial construction projects, the lintel is installed with blockwork built tightly against its inner face and a mortar bed applied before floor units are laid. This installation method promotes even load distribution and helps maintain structural integrity throughout the building. With its heavy-duty design, generous dimensions, and corrosion-resistant finish, the HD/K-90 lintel offers dependable long-term performance in demanding masonry applications.
