Hinges for use in environments with a risk of corrosion should be made of stainless steel or plastic to ensure lasting functionality and low maintenance. Models of stainless steel A4 (quality class 4) as well as hinges of detectable, FDA-compliant plastic are especially well suited for such applications.

Suitable hinges for environments with corrosion risk

• Stainless steel hinges (e.g. GN 237, GN 237.3, GN 136, GN 129.2, GN 129.5, GN 1362, GN 1364): Robust with long-lasting corrosion resistance, also available as heavy duty and elongated variants to meet special requirements.
• Special variants: A4 stainless steel (GN 237.3) for aggressive media (e.g. coastal regions, chemical exposure, food processing), detectable plastics (GN 237.1) for hygiene-critical areas.
• Accessories of stainless steel (e.g. GN 2376, GN 2372, GN 2370): Assist with mounting in areas with a risk of corrosion.

What does this mean in practice?

Choosing hinges of stainless steel or high-quality plastic ensures that doors, covers and hoods can be hung conveniently and remain reliable over the long term. This means that you can benefit from an extended service life for the machine components, avoid downtimes due to rust or material fatigue and satisfy strict hygiene requirements. As user, you can flexibly respond to various environmental conditions and improve the reliability of your application – ideal for outdoor installations, in food processing or chemical plants.Numerous variants are available within the indicated product family for precise adaptation to the specific requirements, and customized special designs can even be ordered with specific materials, dimensions or functions.

Compared with conventional hinges, heavy duty hinges offer significantly more robustness and are designed for withstanding high stresses. For example, they are specially designed for applications in which large, heavy door leafs, covers or housings subject to frequent movement cycles must be hung so as to remain reliable and free of play. The main difference lies in the more solid construction as well as in the selection of particularly resistant materials.

Typical differences – heavy duty hinges versus standard variants

• Heavy duty hinges (e.g. GN 237.3, also in the stainless steel A4 version) are characterized by reinforced hinge bodies and pins.
• When extreme requirements apply, corrosion-resistant stainless steels are used to ensure reliable functioning even in rough production environments, outdoors or in contact with aggressive media.
• Heavy duty hinges are optimized for highly continuous operation and the near absence of wear.
• The screw fastenings and attachment points are also designed for increased forces so that even very heavy doors can be moved reliably and with repeatable precision.

Which options are available for heavy duty hinges?

• The selection ranges from standard to horizontally elongated versions. Users can therefore specifically adapt the load path to the overall design and reduce the risk of collisions.
• Material variants such as stainless steel A4 allow for use outdoors or in food-processing equipment thanks to the extreme resistance to rust and chemicals.
• Screw fastenings or special threaded plates (such as GN 2376 or GN 2372) simplify the mounting of solid doors and covers. This makes for flexible installation and reliable processes.

Heavy duty hinges: Recommended use

• When heavy components must be hung reliably, precisely and with low maintenance requirements.
• For applications in rough, damp or aggressive environments – such as in shipbuilding and chemical- or food-processing plants.
• Anywhere that standard hinges reach their design limits and greater reliability under continuous loads is called for.

Special hinges from Ganter Norm go beyond the basic pivoting function of hinges to offer additional functionality to significantly improve ease of use, operating safety and system flexibility. Hinges and supplemental products from Ganter are thematically arranged into various categories. This ensures that you can quickly find the right solution for your project. You will find a compact overview below – in each case with a brief, practical description:

• Hinges
  This is the central category for pivoting mounting of doors and covers. Here you can choose from a large range of hinge types and search specifically by material, load capacity, mounting options or additional functions – for everything from switch cabinets to heavy machine gates.

  Interior or multiple-joint hinges allow for large opening angles and remain invisible from the outside. The mounting is hidden, which makes for a clean external look and improved vandalism protection.

• Cerniere, regolabili
  These hinges have elongated holes for easy adjustment, such as for adapting to door gaps or compensating for tolerances.

• Cerniere, rimovibili
  Detachable hinges consist of two separate halves, making it easy to remove doors or covers. This saves time with installation or removal – especially for heavy elements.

• Cerniere a frizione regolabile
  Here the rotation resistance can be infinitely adjusted across the entire opening path. This keeps covers open in any position and prevents them from falling closed on their own.

• Cerniere, con bloccaggio
  These hinges can be locked in any desired position with a hand lever, making assembly and maintenance work easier.

• Cerniere con funzione di posizionamento
  These hinges latch with a tangible and audible click at a specific opening angle. This keeps a door temporarily open without falling closed – ideal for recurring operating steps.

• Cerniere con richiamo a molla
  An integrated spring mechanism ensures that the cover or door automatically returns after opening. This allows for a controlled closing movement, such as on service access points of machines.

• Cerniere con funzione di commutazione elettrica
  These hinges have integrated safety switches. When the door is opened, it automatically interrupts a circuit or signals the opened state – ideal for protective enclosures where safety is a priority.

Practical aspects and user benefits

Special function hinges from Ganter are useful when you need custom motion control, safety functions or the advantages of integration.

• For example, a maintenance cover with adjustable friction could be held in any open position to free up the hands of the technicians – without additional supports.

There are many different ways to mount hinges. Selecting the right mounting method is critical for ensuring that the hinges function optimally on doors, covers or panels in machine or plant construction and in automation solutions. Typical mounting methods include standard screw fastening, welding and special methods of fastening to profile systems or panels. Depending on the selected hinge type – such as GN 237 (screw-mounting), GN 1366 (weldable) or GN 161 (for aluminum profiles) – the advantages for specific applications can vary.

Available mounting methods for hinges

• Screw fastening: Most hinges can be directly fastened to frames and doors with screws, e.g. GN 237, GN 437.1 or GN 138. This is ideal when simple removal or readjustment is desired.
• Welding: Models such as GN 1362 (sheet metal hinges, stainless steel, for welding) or GN 1366 (hinges, steel profile, for welding) are permanently welded. This ensures especially strong mounting and is suitable for high requirements in terms of load capacity and vandalism protection.
• Fastening for profile systems and panels: Special hinges are available for attaching to aluminum profiles or panels, such as GN 161, GN 2295 or GN 2291, which can be precisely integrated into profile systems. This allows for quick and reliable mounting in modular systems.
• Use of accessories: Spacer plates (GN 2370), threaded plates (GN 2372, GN 2376) and bolt sets (GN 2290) are used when flexible adaptations are required to handle diverse installation situations or compensate for tolerances.

Important criteria for selecting the mounting method

• Material and environment: Consider whether the hinge will be used in corrosive or hygienic environments or areas exposed to special stresses. Stainless steel variants and special fastening elements ensure reliable functioning even under challenging conditions.
• Load requirements: For large covers or heavy loads, heavy duty hinges such as GN 237.3 for screw fastening or weldable designs like GN 1366 offer good options.
