yoyicassia@hotmail.com Hollow Metal Door Panel
Product Overview
A hollow metal door panel consists of two precision-formed galvanized steel sheets welded around a reinforced internal structure—typically a honeycomb core or vertical steel stiffeners. This unique design delivers exceptional rigidity and impact resistance while keeping weight low.
Unlike wood or composite doors, hollow metal panels are non-combustible, moisture-resistant, and virtually maintenance-free. They provide an unbeatable lifecycle cost for offices, schools, hospitals, and industrial facilities.
Key benefits at a glance:
30–40% lighter than solid metal doors
Customizable sizes, colors, and hardware prep
