Technical Resources
Architectural Specification Guide
Engineering standards, load capacities, material chemical compositions, and installation guidelines for SSISKCON hardware.
Dimensional Precision
All SSISKCON hinges are machined to a tolerance of ±0.5mm, ensuring alignment and preventing door drop.
100% Solid Stainless
Machined from solid Premium-Grade stainless steel. No plating or clear coatings that flake, peel, or rust over time.
CAD & BIM Library
Access 2D AutoCAD dwg and 3D Revit models for specification drawings. Gated for trade convenience.
Access DrawingsMaterial Specification
We manufacture exclusively in premium-grade stainless steel. The chemical composition is strictly tested per batch to ensure marine-grade resistance and structural density.
| Element | Percentage | Function in Alloy |
|---|---|---|
| Chromium | 18.0% - 20.0% | Forms self-healing chromium oxide passive film, preventing rust. |
| Nickel | 8.0% - 10.5% | Enhances corrosion resistance in acid/marine environments, boosts durability. |
| Manganese | 2.0% max | Improves tensile strength and structural leaf rigidity during forging. |
| Silicon | 0.75% max | Acts as deoxidizer during machining process, ensuring grain stability. |
Load Capacity Guidelines
Recommended load limits based on standard wooden and metal door specs. Adding a third hinge increases total door weight capacity and reduces frame tension by distributing leaf shear forces.
| Hinge Size | Max Weight (2 Hinges) | Max Weight (3 Hinges) | Application Class |
|---|---|---|---|
| 3" x 2" x 2.0mm | 30 kg (66 lbs) | 45 kg (99 lbs) | Light residential doors, cabinets |
| 4" x 3" x 2.5mm | 55 kg (121 lbs) | 75 kg (165 lbs) | Standard residential & office wood doors |
| 4" x 4" x 3.0mm | 80 kg (176 lbs) | 110 kg (242 lbs) | Heavy entry doors, commercial doors |
| 5" x 4" x 3.5mm | 110 kg (242 lbs) | 150 kg (330 lbs) | Industrial doors, heavy structural gates |
Standard Compliance Certificates
