Professional Marine-Grade Articulation
Engineered for extreme environments, this 1500mm continuous piano hinge is manufactured from premium AISI 316 Stainless Steel. Featuring a 1.5mm leaf thickness and a robust 4.0mm pin, it provides superior weight distribution across its entire length to eliminate door sag and structural fatigue.
- Corrosion Defiance: SS316 alloy contains molybdenum for superior resistance to chloride pitting in saltwater applications.
- Precision Engineering: Features countersunk holes with 101.6mm spacing (4 inches) for a perfectly flush, snag-free installation.
- Smooth Operation: Tight-tolerance knuckles and a straight-pin design ensures friction-free, silent movement under heavy industrial loads.
Ideal for boat hatches, heavy-duty cabinet doors, outdoor gates, and industrial toolboxes where longevity and aesthetics are paramount.
Frequently Asked Questions
- Will this hinge rust in direct saltwater contact?
- No. Unlike standard 304 stainless steel, this hinge is forged from AISI 316 grade stainless steel which includes 2-3% Molybdenum. This specific chemical composition prevents pitting and crevice corrosion in high-chloride saltwater environments.
- Is this hinge strong enough for a heavy engine hatch?
- Yes. The continuous 'piano' design distributes weight evenly along the entire 1500mm length. The 1.5mm leaf thickness and precision-fitted 4.0mm pin are engineered to handle heavy industrial and marine loads without sagging or binding.
- Does it require special screws for the countersunk holes?
- The hinge features precision-punched countersunk holes designed for standard flat-head marine screws. This ensures the screw head sits perfectly flush with the leaf surface, providing a seamless finish and preventing snags.
