Overview
Engineered specifically for heavy architectural facades, luxury cladding, and stone millwork, this Heavy-Duty 304 Stainless Steel Concealed Invisible Hinge delivers unrivaled load-bearing strength and seamless 180-degree articulation for sintered stone, natural marble, porcelain slab, and composite architectural doors. Cast from solid, corrosion-resistant SUS304 stainless steel with 6 mm thickened mounting flanges and reinforced multi-link pivot arms, this specialized hidden hinge supports extreme panel weights ranging from 150 kg (330 lbs) up to 300 kg (660 lbs). It conceals entirely within the door gap and jamb, preserving continuous, uninterrupted stone veining and minimalist architectural lines.
