The PARK Weld-On Hinge is a heavy-duty, customizable metal hinge manufactured by China-based PARK—specializing in secure, permanent installation for high-load applications. Unlike screw-on hinges, this weld-on hinge uses welding to fix to metal surfaces, eliminating risks of loose screws or structural failure under heavy weight. It is crafted from high-grade stainless steel, ensuring corrosion resistance for indoor and outdoor use, and covers a wide load range (25Kg–325Kg) via 11 standard models (S114211–S114221). Whether for industrial equipment, warehouse storage, or transportation vehicles, this hinge balances durability, precision, and ease of installation, making it a cost-effective solution for heavy-duty door and gate systems.
Each PARK weld-on hinge model is engineered for specific load needs, with precise dimensional control:
Model S114211: L=1.580in, H=0.380in, D=0.315in, d=0.197in, load=25Kg, weight=23g (ideal for light-duty cabinet doors);
Model S114216: L=3.940in, H=0.770in, D=0.630in, d=0.394in, load=105Kg, weight=153g (suitable for medium industrial doors);
Model S114221: L=7.870in, H=1.100in, D=0.905in, d=0.590in, load=325Kg, weight=642g (designed for heavy-duty applications like truck cargo doors);
All models feature consistent hole diameter (d) tolerance (±0.005in), ensuring alignment during welding.
Stainless steel material: Resists rust and corrosion, even in humid or outdoor environments (e.g., rain-exposed trailer gates);
High tensile strength: The metal matrix avoids bending or cracking under max load, with a service life of over 10 years in typical use;
Smooth surface finish: Reduces friction during hinge rotation, preventing wear and ensuring quiet operation.
Permanent fixation: Welding creates a seamless bond between the hinge and metal frame, stronger than screw-on designs (no risk of loosening from vibration);
Time-saving installation: No need for drilling holes—simply position and weld, cutting installation time by 30% compared to traditional hinges;
Wide compatibility: Works with carbon steel, stainless steel, and aluminum frames (adjust welding parameters for different base metals).
Shock resistance: Endures sudden impacts (e.g., slamming heavy doors) without structural damage;
Temperature resistance: Maintains performance at -20℃–120℃ (suitable for cold storage or high-temperature workshop doors);
Low maintenance: No need for regular lubrication or screw tightening, reducing long-term upkeep costs.
The Weld-On Hinge is versatile across industries requiring secure, heavy-load hinges:
Industrial Equipment: Used on machinery enclosure doors (e.g., manufacturing robots, metal presses) to withstand frequent opening/closing and machine vibration;
Warehousing & Logistics: Installed on warehouse shelving doors and heavy-duty storage cabinets, supporting loads of 50Kg–200Kg;
Transportation: Applied to truck cargo doors, trailer gates, and bus luggage compartments—resisting road vibration and outdoor corrosion;
Construction: Used for steel structure gates (e.g., factory entrance gates, construction site barriers) that require long-term outdoor durability;
Marine Industry: Suitable for small ship hatches (stainless steel resists saltwater corrosion, ensuring safety in coastal areas).
We understand that standard models may not fit all needs, so we offer tailored solutions:
Size Customization: Adjust length (L), height (H), or thickness (D) to match unique door/gate dimensions (e.g., extra-long L=10in for large industrial gates);
Material Customization: Offer optional stainless steel grades (e.g., 304 for general use, 316 for saltwater environments) based on corrosion resistance requirements;
Bulk Order Support: Provide flexible production for large quantities (e.g., 10,000+ units for truck manufacturers) with discounted pricing;
Logo/Marking Service: Add custom logos or part numbers to hinges for brand identification or inventory management;
After-Sales Guidance: Offer welding parameter sheets and installation videos to ensure proper use, and provide replacement for defective products within 1 year.
The largest model (S114221) supports up to 325Kg—sufficient for most heavy-duty industrial and transportation applications.
Yes. The smooth stainless steel surface can be sanded and painted with industrial-grade paint to match door/gate aesthetics (ensure paint is heat-resistant if used near high-temperature equipment).
Only standard welding equipment (e.g., MIG/TIG welder) and basic measuring tools (tape measure, level) are required—no specialized tools needed.
Yes. It maintains flexibility and strength at -20℃, making it ideal for cold storage door systems.
For small custom batches (100–500 units): 5–7 days; for large custom orders (1,000+ units): 10–12 days.
