Upvc Window Reinforcement & the rumors surrounding it

Have you ever heard of GI Reinforcement? What is it actually? And what role does it play as far as UPVC windows and doors are concerned?

Well there are many rumours in the market regarding GI Reinforcement but what are the rumours and how true they are let us try to find it.

Let us first try to understand what is GI Reinforcement? GI Reinforcement is a kind of ‘U’ or ‘C’ shaped iron strip which is inserted into UPVC Profiles. Well there are two main reasons why a GI Reinforcement is Inserted into a UPVC Profile

The first reason is that inserting GI Reinforcement inside a profile provides strength and rigidity to the profile. You must have heard many a times that UPVC Profiles bend while installation. This is not due to the quality of the upvc profile and does not necessarily mean that the profile is of an inferior quality but because of the absence of the GI Reinforcement, the profile could not get support, strength and rigidity.

But most of the time the customer complains regarding the Profile since they do not understand the actual reason behind the situation. Well this can be a serious issue for the profile company because they might lose goodwill among customers without actually being at fault!

So next time when anybody complains to you regarding your profile then kindly try to find out if at all GI Reinforcement had been used in the upvc windows and doors or not because if not then the profile company is not to be blamed in this case. It is the fault of the window or the door manufacturer.

Also another problem that customers face due to the absence of GI Reinforcement is when hardware like screws etc. are fixed to the upvc profile then these hardware should make its way through the GI Reinforcement for ultimate strength otherwise it is like trying to tighten a screw into plastic. As we all know that even if it of a very superior quality UPVC, eventually it is a plastic material and hence we can very well imagine what would be the outcome. But if the screw penetrates deep within the metal then it will provide ultimate strength to the hardwares which in-turn adds to the durability of your Upvc windows and doors.

However that brings us to the question what should be the thickness of GI Reinforcement?

Generally, in the market we can find GI Reinforcement from 1.2 mm upto 3.5 mm as per different upvc profile, door and window requirement. So which one is recommended for use?

If you are making a normal and standard sized upvc window or door then it is recommended that you use GI Reinforcement with a thickness of 1.2 mm to 1.5 mm.

Now there are rumours in the market that certain UPVC window making machines can weld the profile and the GI Reinforcement together. Well if you have also been told this by someone then you have been lied big time!

This is completely a false claim. No matter whichever machine you buy in this world be it SAICON PORTABLE UPVC WINDOW MAKING MACHINE or any other machine no matter how expensive it may be, know for sure that no machine has the capacity to weld above a temperature of 350 Degree Centigrade. This GI Reinforcement which we also know by the name of galvanised steel has a melting point of 1500 Degree Centigrade. So it is not possible with machines bearing highest welding point of 350 Degree Centigrade to weld GI Reinforcement with a melting point of 1500 Degree Centigrade. Just think about it………..

Understand for sure that this is not possible logically. That is the reason why GI Reinforcement are kept short by at least an inch from the ends of the UPVC Profiles so that they do not interfere with the upvc profile during welding.

So I believe that by now you have been able to understand the importance of GI Reinforcement in UPVC Profiles and the things that you need to keep in mind while using it.
