NL-19® is a proprietary surface treatment that FOREVERBOLT has an exclusive partnership with. NL-19® surface treatment alters the surface by removing the free iron and the imparted impurities during manufacturing.... The net gain is NL-19® surface treatment when applied will prevent stainless steel from corroding.... NL-19® surface treatment creates a boundary layer against the elements, thus resulting in less surface contamination which means less maintenance.

All Stainless steel will corrode at some point. Our NL-19®surface treatment will dramatically decrease the possibility or corrosion. 

There will be some slight exposure, but nothing significant.

If the raw materials are scratched or damaged they will be exposed to the environment, they will have to be processed again. There is currently no way to reprocess in in the field. However, we ensure minimum damage while in transit.

Currently there is no competition and the cost varies based on the project size and per piece count. Typically the cost is 100 to 200 percent higher than non-treated stainless steel.

There are some chemical steps in the process, but there are also a variety of other “proprietary” steps involved in creating a final product. In total it is a complicated 19 step process that we have developed over 20 years. We profess that we are making a truly green product.

The product is guaranteed for life, (see disclaimer) provided there is no damage to the fasteners through poor installation methods.... There have not been any reported failures in the past 20 years of using this process or early iterations of the process.

Once the process is complete it is done, there is no cure time.

The process is totally inert. And we have preformed many tests, even out gassing is nonexistent.

The process is completely clean and nothing will leach into the environment.

Galling will happen if the fastener is over torqued, however this process will reduce the galling significantly. By adding white lithium grease or WD-40 it will help considerably.

It is not mandatory, but can be used to significantly reduce galling.

We have not seen any advantage or disadvantage to using NL-19® with rebar and concrete.

As long as it is a stainless steel product, yes NL-19® can be applied

No, it has to be processed in house.

It can be powder coated or painted like any other metal surface at an additional cost.

This is a loaded question because power-coating is a process that needs to be controlled and done correctly. This is also conditional to the application and preparation to the surface prior to power coating....

Yes, NL-19® surfaces can be brushed with Scotch Bright or a similar type of scuffing material. Do not use steel wool, it will impart contaminates which will contaminate the processed surface.
