Cruise quality = Corrosion class C5M

Home   |   Quality

QUALITY

On a cruise ship, the durability of the furniture is pushed to the extreme. High traffic, heavy use and weather of all kinds set the demand for quality. Burning tropical sun combined and constant exposure to salt.

CRUISE QUALITY material and processes

We differentiate between standard contract quality and cruise quality in following way: The selection of material and the quality processes.

Marine grade stainless steel 316L/317L

The fittings such as screws, nuts, bolts, clams and nails that hold the frames together is made of stainless steel 316L, which is the lower carbon version of SS316. Highly resistant to corrosive environments and elevated temperatures. The best option for high stress areas. Njord also offer SS317, which is more resistant to sodium hydroxide found in the soaps and detergents used to clean onboard.

Virgin aluminum frames with protective pre-treatment

Selection: Njord always use 100 % new virgin aluminum. We are not tempted by the lower cost of mixed or recycled aluminum because it offers a lower purity. It may come from a variety of previous product, such as soda cans or scrap metal and the recycling process compromises the anti-corrosion capability of aluminum. Quality: When the frame is constructed it is being sanded and sandblasted. With a pure product we can start the proper cleaning and protective pretreatment of the alu surface. In a combination of acidic degreasing, phosphating and washing/drying, the frames are being prepared for powder coating in a 100 % contamination free zone.

Smooth Weldings

There are only a few things in life that are better than a perfectly smooth welding. But only a few. The type of furniture determines which type of welding is needed. TIG/WIG are the most common methods, but the quality highly depends on the welder. In Njords Ark, we double and triple check the final look of the welding to avoid “bubble gum”

High Density Wicker

The wicker fibers are HDPE fibers. That is, High Density Polyethylene. It outperforms any other fiber because it offers more tensile strength and intermolecular force.

  • Inherently colored fibers.
  • FR treated
  • UV protected.
  • Resistant to a variety of chemical solvents.
  • Lighter, stronger, harder, and can withstand higher temperatures.
  • Can withstand temperatures of 230 degrees Fahrenheit.
  • Has absorptive characteristic that dampens vibrations.
  • Has a higher Crystallinity than Polypropylene. Crystallinity influences hardness and density, hence the name High Density Polyethylene.
  • Polyethylene is the most widely used plastic. Eco-friendly material that can be recycled!

Super Durable Powder Coating

When the frames are dried and wiped the first primer coating is applied in a thickness of 60-80um. The entire batch is checked for defects before a topcoat is applied in a thickness of 60-80um. After final inspection, 2 sample pcs go through accelerated corrosion test (Machu), strengths adhesion test, Ageing test, salt spray test, and weatherability test.
