Core Product Features & Competitive Advantages

2.1 Robust All-Steel Heavy Load Structure

Whole hinge is stamped and bent from solid thick steel plate, far superior in tensile strength, rigidity and impact resistance compared to zinc alloy hinges. It supports heavy metal cabinet doors, resists torsion and permanent deformation, perfectly fits heavy industrial equipment protection covers and power enclosures.

2.2 White Zinc Plating Reliable Anti-Corrosion Protection

Uniform white zinc electroplated coating creates a dense barrier layer on the steel surface, effectively preventing rust, oxidation and slight splashing moisture corrosion. Stable performance in indoor workshops and mild semi-outdoor environments, greatly extending hardware service life and reducing replacement frequency.

2.3 Built-In 90° Angle Limiting Safety Design

Internal mechanical limiting structure locks the maximum opening at exactly 90 degrees, preventing the door from over-swinging and hitting wiring, equipment components or operators. Greatly improves operational safety for control panels, instrument doors and mechanical safety guards.

2.4 Flat Base Simplified Screw Mounting

Flat compact L-shaped base plate features a smooth mounting surface, directly fixed onto cabinet frames with standard screws without threaded studs. Installation process is simpler, no need for backside nut locking, saves assembly labor time for cabinet manufacturers and batch production lines.

2.5 Tool-Free Lift-Off Disassembly Mechanism

The Φ8 steel spindle pin can be pulled out by hand to fully remove the door without disassembling the fixed base bracket. It facilitates internal equipment wiring modification, faulty component maintenance, cabinet packaging transportation and large-volume batch assembly work.

Typical Application Scenarios

  1. Heavy industrial electrical control cabinets, low-voltage distribution boxes, PLC and frequency converter enclosures
  2. CNC machine tool safety protective covers, automation equipment housings, industrial testing instrument boxes
  3. Mechanical engineering equipment electrical boxes, indoor charging pile control cabinets, weak current panel enclosures
  4. Cabinets requiring controlled 90-degree opening to avoid collision damage
  5. Standard sheet metal equipment projects that prefer flat screw-on base hinges for easy installation

Installation & Maintenance Guide

4.1 Installation Steps

  1. Align the flat base plate against the cabinet mounting beam and mark screw hole positions.
  2. Drill mounting holes and fasten the base firmly with machine screws.
  3. Fit the door sleeve onto the hinge barrel, insert the Φ8 steel pivot pin to lock the assembly.
  4. Test door rotation to confirm 90° maximum opening limit and smooth pin extraction.

4.2 Installation Quantity Recommendation

  • Door height ≤ 500mm: Install 2 pieces symmetrically
  • Overweight steel door or height above 500mm: Add a third hinge in the middle position for balanced load bearing.

4.3 Maintenance Reminders

Applicable for dry indoor and mild semi-outdoor environments only. Avoid long-term exposure to rain immersion, acid & alkali chemicals, corrosive gas and coastal salt fog atmosphere. Wipe the zinc-plated surface with dry cloth regularly; apply a small amount of anti-rust lubricant on the pivot pin periodically to maintain smooth pulling and rotation.
