“DRIPGRIP” Roofing J / L Bolts (Hooks)



1) Corroded roofing bolt

2) Fixing arrangement of “DRIPGRIP”

Use of polycoated roofing accessories is an established practice in India, now. But, correct use of these accessories to fight corrosion and leakage through J/L roofing hooks needs customer education.

 
Incorrect pre-treatment : GALVANISING :
 
When we supplied these hooks earlier, the pretreatment given was GALVANISING before polymer coating the bolts. But, it was quite an unfriendly & non-cohesive surface for polymer coating. More glazed the galvanising, worse it was for polymer coating. We learnt from the feed back by our numerous customers that this treatment of galvanising is hardly suitable for corrosion resistance in the longer run. For over two years, we conducted trials and produced a quasi-monolithic polymer coating. This coating gives enhanced peel off force and abrasion resistance and  malleability to the coat. Movement of purlins due to wind pressures, though insignificant, causes rupture of coating exposing the mother surface, giving rise to corrosion. As pioneers, in polymer coated roofing accessories, we decided to give a “perfect system” & NOT a “workable system”.
 
Patented Product :
 

Now, we have successfully invented a better surface preparation than G.I. for effective polymer coating, without compromising on corrosion resistance as observed in G.I. As a result of our research, we have perfected a process of Zinc-Phosphating the bolts instead of Galvanising before Polymer coating. The process has Patent No. 204161 Dtd. 12/01/2007. Our many esteemed customers have conducted extensive and destructive trials on these bolts. In both cases the results are astonishing. The comparison of Zinc - Phosphated Polymer coated bolts and Galvanised Polymer coated bolts, is enclosed.

Destructive test can be taken on our Zinc – Phosphated bolt and GI Polymer coated bolt by using a small hammer and a razor blade. It reveals that on razor cutting, coating on our Zinc-Phosphated bolt CAN NOT be peeled off, whereas coating of G.I. bolt will EASILY BE PEELED OFF LIKE A BANANA SKIN. On hammering, the coating it is locally dented but the coating is not removed like G.I. coated bolt. Life of these ZnPh Polycoated bolts is enormously high to that of G.I. polycoated bolts.

 
Universal NAGGING Problem :
 

NAGGING problem of LEAKAGE is universal irrespective of geographical location and type of industry. To fight this problem, our “DRIPGRIP” accessories are made from Special Virgin Polymers added with special UV Stabilizers, to resist Ozone/Ultra violet effect and Temperature factors. Its performance conforms to ASTM E-179: 81.

“DRIPGRIP” accessories consist of Thrust Washer instead of G.I. Washer, Polymer Washer (for sealing), Polymer Cap with skirting covering G.I. nut. With this information, as customer education, wise “choice” is the right product “DRIPGRIP” for any roof work. Inclusion of this in standard specifications instead of mere “Polymer coated bolts for roofing” will give right value of this “choice”.

Various Industrial Units & Consultants of worldwide repute have included in their New Standards.
