FREQUENTLY ASKED QUESTIONS
NL-19(SM) is a proprietary surface treatment that Foreverbolt has a partnership with. The surface treatment alters the surface and prevents corrosion. The net gain is NL-19(SM) surface treatment will not rust or corrode like non-treated stainless steel. NL-19(SM) surface treatment creates a boundary layer against the elements, thus resulting in less surface contamination which means less maintenance.
No, you do not compromise the surface.
There will be some slight exposure, but nothing significant.
If the raw materials are chipped or broken they will be exposed to the environment, they will have to be processed again. There is currently no way to spot process small pieces 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. Typoically the cost is 20 to 30 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 the last 15 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 pieces, there have not been any reported failures in the past 15 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.
Yes we can treat the finished processed surface to look duller with no shine. It can be powder coated or painted like any other metal surface at an additional cost.
Yes, in general, if done properly it can increase the life of the material significantly. This is a loaded question because power-coating is a process that needs to be controlled and done correctly.
Yes, NL-19 surfaces can be brushed with scotch brite or a similar type of scuffing material. Do not use steel wool, it will impart contaminates which will contaminate the processed surface.
