Vinyl coated hot galvanized driven fasteners and method for manufacture thereof

Abstract

Nails are manufactured using a sequence of steps including hot galvanizing of the nails with a zinc/tin/flux composition followed by vinyl coating to provide fasteners which resist corrosion that may result from chemically treated wood and cement infused materials.

1 . A method for manufacture of corrosion resistant articles useful in the assembly of chemically treated wood products and corrosive materials comprising, in combination, the steps of:
 (a) galvanizing said article by a zinc galvanizing process to provide a zinc base coating of said article;   (b) cleaning said article in a solution;   (c) drying said article;   (d) coating said article with a liquid vinyl composition; and   (e) drying and curing the vinyl coating.   
   
   
       2 . The method of  claim 1  comprising the step of forming a zinc base coating on said article with a roughness in the range of 7-10 peaks per inch with heights ranging from 0.001-0.009 in and averaging about 0.003 inches prior to coating with said vinyl composition. 
   
   
       3 . The method of  claim 1  wherein the galvanizing comprises a process selected from the group consisting of hot galvanizing and hot dip galvanizing. 
   
   
       4 . The method of  claim 1  wherein galvanizing comprises coating the article with said layer of zinc in the range of about 0.8 to 1.8 oz/ft 2 . 
   
   
       5 . The method of  claim 2  wherein coating the article with said vinyl composition comprises coating with a layer of vinyl in the range of about 0.5 to 0.7 oz/ft 2 . 
   
   
       6 . The method of  claim 1  wherein the step of cleaning the article comprises the step of cleaning in a solution selected from the group consisting of water, a caustic solution and an acidic solution. 
   
   
       7 . The method of  claim 4  wherein coating the article with said vinyl composition comprises coating with a layer of vinyl in the range of about 0.5 to 0.7 oz/ft 2 . 
   
   
       8 . A method for assembly of a structure wherein at least components of the structure comprise wood treated with ACQ or comprise cement lap siding comprising the steps of:
 fastening building components made in accord with the method of  claim 1 .   
   
   
       9 . A method for assembly of a structure wherein at least components of the structure comprise wood treated with ACQ or comprise cement lap siding comprising the steps of:
 fastening building components made in accord with the method of  claim 2 .   
   
   
       10 . A method for assembly of a structure wherein at least components of the structure comprise wood treated with ACQ or comprise cement lap siding comprising the steps of:
 fastening building components made in accord with the method of  claim 5 .   
   
   
       11 . A method for assembly of a structure wherein at least components of the structure comprise wood treated with ACQ or comprise cement lap siding comprising the steps of:
 fastening building components made in accord with the method of  claim 6 .   
   
   
       12 . A method for assembly of a structure wherein at least components of the structure comprise wood treated with ACQ or comprise cement lap siding comprising the steps of:
 fastening building components made in accord with the method of  claim 7 .
