Fusion-welded

Fusion welding joins two materials into one unit by heating them past their melting point(s) with temperatures usually over 500°F. This creates a more secure bond than mechanically joining two pieces together using screws, adhesives, or other means of attachment.

Mechanically bonded materials develop gaps, leaving room for water and air leakage and compromising the structural integrity of the unit. Fusion-welded materials will maintain their strength and structural integrity for many years and will create a much more secure seal against moisture and air.
