Focusing on cost-effectiveness and universal applicability, this keel features a standard U-shaped cross-section that ensures uniform stress distribution during installation. The hot-dip G90 galvanized surface treatment forms a dense protective layer, effectively preventing rust and corrosion in indoor dry environments. Its customizable standard lengths simplify on-site cutting and installation, reducing construction time. Compared with traditional wooden keels, it has better fire resistance and dimensional stability, avoiding deformation caused by moisture or termite erosion, solving the common pain points of wooden keels' short service life and poor stability.
