Heavy Duty Industrial Hinges for Cases, Cabinets & Enclosures
0 ProductsHeavy duty hinges are robust industrial hardware designed for heavy load applications on cases, cabinets, equipment enclosures and storage boxes. Built with high-strength metal materials, these heavy duty hinges provide excellent load-bearing capacity, smooth rotation and long service life under frequent use. Featuring solid construction and corrosion-resistant finishes, they perform reliably in industrial, outdoor and harsh working environments. Suitable for all types of heavy cases, protective enclosures and large cabinet doors.

Frequently Asked Questions About Heavy Duty Hinges
We have no minimum order for in-stock catalog items - order even 1 piece if you need it. Shipping is freight collect for sample and small quantity orders. For custom laser engraving, private labeling, or non-catalog specifications, MOQ varies by product model and manufacturing process. Contact our sales team with your specific requirements for a precise quote and lead time.
We manufacture in 5 primary materials, each specified for different operating environments:
- SUS304 stainless steel - excellent corrosion resistance with passivated finishes available for enhanced durability in harsh environments (consult our engineers for specifications). Our most popular choice for marine hardware, food processing equipment, and outdoor enclosures.
- SUS201 stainless steel - cost-effective option for indoor dry environments with good general corrosion resistance.
- Cold-rolled carbon steel (SPCC) - high tensile strength for heavy-load applications, available with zinc, nickel, or chrome plating for corrosion protection.
- Zinc alloy (ZAMAK) - precision die-cast for complex geometries, naturally corrosion-resistant, ideal for decorative and medium-duty applications.
- ABS plastic - lightweight, non-conductive, and chemical-resistant, perfect for electronic equipment cases and medical instrument enclosures.
- In-stock items: Ship within 48 hours of order confirmation.
- Standard catalog models (made-to-order): 7-15 business days.
- OEM / custom tooled products: 25-35 business days depending on part complexity and tooling requirements.

- Material modification: Custom alloys, food-grade 316 stainless steel, and RoHS-compliant materials.
Our factory is ISO 9001:2015 certified and operates under GJB (Chinese Military Standard) quality management systems for defense-grade products. Every batch undergoes rigorous testing before shipment:
- Surface finish testing - coating thickness measurement, adhesion cross-cut test, and roughness inspection ensure consistent finish quality across every batch.
- Load & tensile testing - verified working load and ultimate tensile strength for every latch, hinge, and handle model.
- Cycle durability testing - 10,000+ open/close cycles for moving components.
- Dimension inspection - 100% caliper and gauge inspection for critical dimensions.
- RoHS compliance - all materials meet EU RoHS 2.0 standards for restricted substances.
