Corrosion resistance and ceramic coated screws posted on jul 07 in news.
Ceramic coated scres vs stainless steel.
100 qty 8 x 1 5 8 features.
Ultra guard tan coating ensures corrosion resistant property.
Building supply dealers and catalogs may offer as many as five different types of stainless steel screws.
Ceramic coated screws can be used with both pressure treated lumber and composite decking.
Any manufacturer s stainless steel products will cost more than its coated steel ones.
In any case ceramic is never going to hurt power.
For corrosion resistance stainless steel is the best of the lot.
That is why the screws are made of top quality stainless steel.
Composite deck screws can also be stainless steel but are available in colors designed to compliment and match the colored deck boards trim and railing components.
Ceramic coated screws have performed extremely well in salt spray testing but this does not mean they should be substituted for stainless steel in a marine environment.
So if you need stainless steel deck screws these are one of the best options for you.
In contrast stainless steel does not need to rely on a coating to toughen and protect it.
A more widely seen option is epoxy coated deck screws.
Screws treated with a high quality coating consisting of zinc and aluminum.
Star drive allows easy and fast installation.
As is the case with carbon steel screws a plated stainless steel screw is less likely to corrode aluminum.
For instance titan metal werks a fastener manufacturer charges about 25 for 400 of their acq rated zinc coated with a polymer topcoat 6 by 2 inch splitstop screws.
However stainless steel is reactive with aluminum and when a stainless steel screw is in contact with an aluminum base metal the aluminum is likely to corrode.
It is an alloy that includes a significant quantity of chromium.
The presence of this tough metallic element improves the durability of the steel and adds rust resistant qualities as well.
But these fasteners are expensive.
In terms of durability and corrosion resistance stainless wins over mild steel headers that are coated only externally with ceramic.
Screws made of this material may cost twice as much as coated steel fasteners.
In contrast the same size and number of stainless screws costs about 66.
Whenever you put time or expensive lumber into a clear finished project it doesn t make sense to use anything but stainless steel.
Stainless steel ensures the better strength of the screws.
Basic stainless steel sold as type 302 303 304 or 305 contains 18 chromium and 8 nickel plus other alloys.
