Heavy-Duty Zippers For Marine & Industrial Use



Understanding the basic differences between the industry’s current variety of zipper types is important, not only for a high-quality product, but to stay on the cutting edge of fastener technology. Even the most seasoned professional can benefit from additional product knowledge and may find it especially useful for service expansion or new employee training.


What Qualifies a Zipper as Heavy-Duty?


Industrial-grade zippers are equipped to handle much more stress, frequent use, and harsh environmental conditions than regular zippers. These zippers are manufactured with specialized materials that resist typical wear and tear, ensuring long-lasting functionality.


Materials Used in Heavy-Duty Zippers


Marine and industrial-grade zippers can be constructed with various materials, each offering various pros and cons. The main types of materials used to craft heavy-duty zippers include:


  • Plastics: Plastic zippers (e.g., YKK #10, Vislon zippers) are lightweight, strong, water and UV resistant – making them perfect for marine use.
  • Nylon coil: Flexible and lightweight, typically reserved for applications that require durability.
  • Metals: Brass (corrosion resistant), aluminum (lightweight), and stainless steel (very strong) are some of the most commonly used metals in heavy-duty zippers.

These materials are proven to be long-lasting and perform well under demanding outdoor, industrial, and heavy-duty use conditions.

Zipper Tooth Material Options


When it comes to heavy-duty zippers, tooth material is an essential consideration for high-demand applications. Depending on the potential for exposure to salt water, chemicals, abrasion, or other high-demand conditions, consider the following:


  • Molded Plastic: Zippers with molded plastic teeth, like YKK® VISLON®perform exceptionally well in marine environments as all zipper materials are inherently water and corrosion resistant. Other options, like Sunbrella® SUNZIP™, feature zipper tape that offers added UV resistance.
  • Coil: Featuring nylon teeth, coil zippers like YKK® ZIPLON® easily curve and bend, making them ideal for a variety of heavy-duty applications requiring both flexibility and weather resistance.
  • Metal: Best for indoor projects or applications not exposed to the elements, zipper teeth made from metal prioritize high strength and long-term durability.

Zipper Type Options


The industry offers a vast selection of zipper types that feature your chosen zipper tooth material. Don’t forget, zipper chain can be purchased separately from zipper sliders for extra customization opportunities. Determine which type of zipper is best for your application based on the following pros and cons of popular options:


  • Separating Zippers: Excellent for projects that require the zipper to completely separate, like large marine covers and outdoor apparel. Also called an open-end zipper, these products can be converted to closed-end zippers if needed.
  • Closed-End Zippers: Typically found on cushions, bags, protective covers, and tents, these zippers do not separate at the bottom. Closed-end zippers cannot be converted to separating zippers. Bridge top style zippers are similar but have an added top closure for increased security.
  • Two-Way Zippers: Ideal for large industrial or marine applications, two-way zippers offer versatility and can be zipped from the top or bottom, saving time and effort. Any zipper chain can be converted to a two-way zipper by installing a double pull tab zipper slider.

Common Applications of Heavy-Duty Zippers


Heavy-duty zippers are designed for demanding environments where durability and strength are critical. Their ability to resist damage from elements and frequent use makes them a reliable choice for challenging tasks.


Marine, Indoor, & Outdoor Upholstery


Marine-grade zippers are designed to withstand constant exposure to UV rays and water contact. They’re most often used in boat covers, bimini tops, and awnings to provide durable closures. Their corrosion resistant material makes them ideal for salty, humid conditions. Upholstery cushions, furniture covers, mattress covers, and other high-traffic upholstery applications benefit from zippers with the same performance features.

Industrial Uses


Industrial zippers are valued for their strength and durability under extreme conditions. They are commonly found on tarps, upholstery, protective clothing, and safety equipment, where reliable closures are crucial for equipment and personnel safety.



These zippers are built to withstand high-stress environments, offering longevity and smooth operation despite being frequently used and exposed to tough elements.

Outdoor Gear and Apparel


From sleeping bags to jacket zippers, there are plenty of uses for heavy-duty zippers in the outdoor gear world. Their strength and reliability make them ideal for products used in rugged conditions.



With the ability to resist the wear and tear from both outdoor elements and frequent use, they are an important feature in gear designed for adventurers who demand high performance from their equipment.


Maintenance and Care Tips


Proper maintenance of your heavy-duty zippers can significantly extend their lifespan. Following a regular care routine ensures that the zippers will glide smoothly and prevent unnecessary wear.

Cleaning Procedures


To keep zippers functioning properly, some simple cleaning procedures to perform include:


  • Remove dirt and debris with a damp cloth or soft brush.
  • Don’t use too much force when cleaning since it could cause damage.
  • For marine zippers, rinse them with fresh water to prevent salt from building up.

Lubrication


To keep the zipper pull running effortlessly, follow these lubrication tips:


  • Silicone-based lubricants are excellent for keeping your zipper operating as smoothly as possible.
  • Avoid using oil-based products since they attract dust.

Regular Check-Ups


Providing regular check-ups on zippers will increase their lifespan. Some tips to follow include:


  • Conduct periodic inspections on the zipper teeth to check for wear, tear, and misalignments.
  • If you notice damaged zipper stops, zipper sliders, or bottom stops, quickly repair or replace them.

Factors to Consider When Choosing the Right Zipper


When selecting heavy-duty zippers, there are several important factors to consider that can impact performance and durability, including:


  • Harsh Conditions: For marine and industrial use, opt for corrosion resistant materials that can withstand harsh conditions.
  • Load and Frequency of Use: The heavier the application, the stronger your zipper teeth need to be. Metal zippers or heavy-duty plastics have stronger teeth that are built for heavy loads and frequent use.
  • Fabric Compatibility: Double-check your fabric to make sure it’s sturdy enough to support the zipper’s weight.
  • Design: Use zippers that match the style and structural needs of your project.
