Roofing Hook Bolts

Product Description

Roofing Hook Bolts

In many industries, overhead leakages from the roof  & the resultant corrosion of the roofing accessories are perennial nagging problems. During marketing of our Safety Engineering products, in the past 25 years, we came across a number of events like :

a) Leakage produced harmful gases in a chemical warehouse followed by a chain of events  
b) Dripping water from the roof fell directly into a metal smelter, causing an explosion;
c) Sugar got watered in a sugar factory godown; 
d) In a cement factory, tons of cement turned into cement stone, after roof sheets flew off

In each of the above cases the losses were colossal and the obvious reason was - leakage from the roof above. The purlin bolts were rusted & the bitumen washers cracked after some time, resulting in leakage.

Following mounting costs can not be ignored

a) Frequent change avers of conventional galvanised purlin bolts;
b) Leakproofing the roof joints with bitumen before every monsoon;
c) Sheet damages during leakproofing, giving rise to rooftop accidents;
d) Damages to your goods and plant & machinery due to overhead leakages.

We are the pioneers in the manufacture of "DRIPGRIP" J/L bolt system for protection against corrosion of roofing bolts & prevention of leakages through them. It consists of the following :

I)  J/L Bolt - Polymer Coated with enhanced  mechanical properties;
II) Polywasher - Specially designed to seal the drilled / punched hole of the roof sheet;
III) Thrust washer - Replaces G.I. washer, thrusting the polywasher in position;
IV) Polycap - Covers the protruded thread section of the bolt, preventing corrosion.

Accessories manufactured with foul technical processes have numerous failures like rupturing and peeling off of the coating due to poor adhesion and bond strength resulting in premature rusting and leakages. Someone rightly said, "There is hardly anything in the world that A MAN cannot make a little worse and sell a little cheaper. Those who consider PRICE only are this man's LAWFUL PREY." 

We successfully invented better surface preparation than G.I. for effective polymer coating, without compromising on corrosion resistance property. This product is a patented product under PATENT No. for the same is 820 / MUM / 2000 Dtd. 08/09/2000.

It is necessary to standardise our product by the end users or by the consultants of the project to avoid cheating in spite of spending added value for use of polymer coated accessories - "DRIPGRIP" system for in place of conventional accessories of G.I. Bolts, Bitumen washer & G.I. Nut for this work.
