Core Product Features & Competitive Advantages

2.1 All-Steel Heavy-Duty Load-Bearing Structure

Whole hinge adopts integrated bending thick steel plate stamping forming, far higher tensile strength and load capacity than zinc alloy hinges. It can bear heavier equipment cabinet doors, resistant to deformation, torsion and impact, suitable for heavy mechanical equipment and industrial electrical boxes.

2.2 White Zinc Plating for Excellent Anti-Corrosion Performance

Uniform white zinc electroplating layer forms a protective barrier on steel surface, effectively preventing oxidation, rust and slight water splash corrosion. Stable performance in normal indoor, semi-outdoor and workshop environments, prolongs service life of metal hardware.

2.3 Fixed 90-Degree Limit Opening for Safety Control

Built-in mechanical stop structure restricts door opening angle strictly at 90°, avoids over-swinging to hit surrounding components, cables or operators. Perfect for control panels, instrument doors and safety protection enclosures with limited opening requirement.

2.4 M10 Threaded Stud Firm Installation Method

Adopts robust M10 external threaded bolt for penetrating panel mounting, lock with nuts on the backside. Combined with two auxiliary fixing holes on the L-shaped bracket, the mounting structure is ultra-solid, not easy to loosen under vibration, shock and frequent switching scenarios.

2.5 Tool-Free Lift-Off Detachable Function

The main Φ8 steel pivot pin can be directly pulled out horizontally to detach the door from cabinet frame without dismantling fixed brackets. Greatly simplifies equipment internal wiring maintenance, component replacement, cabinet transportation and batch assembly workflow.

Typical Application Scenarios

Heavy-duty electrical control cabinets, power distribution boxes, low-voltage switch enclosures and PLC control panels
Mechanical automation equipment housings, machine tool protective covers, industrial testing instrument boxes
Construction machinery electrical boxes, charging station control cabinets, semi-outdoor weak current equipment casings
Equipment doors that require 90° angle limit to prevent excessive opening collision
Sheet metal cabinet projects needing high-strength all-steel anti-rust detachable hinges

Installation & Operation Guide

4.1 Installation Steps

Drill a through hole matching M10 thread on cabinet frame mounting beam.
Insert the M10 threaded stud through the hole, fasten lock nut tightly on the rear side.
Secure the L-shaped bracket additionally with screws through the two reserved holes for double reinforcement.
Align door hinge sleeve with the barrel, insert Φ8 steel pin to complete assembly.
Swing door to verify 90° maximum opening limit and smooth pin pull-out detachment.

4.2 Installation Quantity Recommendation

Door height ≤ 500mm: Install 2 pieces symmetrically
Heavy steel door or height over 500mm: Add the third hinge in the middle position to share weight load.

4.3 Maintenance Reminders

Suitable for indoor and mild semi-outdoor environments. Avoid long-term immersion in water, acid-base liquid, strong corrosive gas and high-humidity coastal salt fog atmosphere. Wipe zinc-plated surface with dry cloth regularly; apply anti-rust grease on the Φ8 pivot pin periodically to ensure smooth pulling and rotation.
