Misleading Article
Author: EKDebrah Posted: 2012-09-17 07:21:22 Bad Article Title!!! This could cause a stir within the common populace, and worse still affect the business of alu-zinc producers. The technical specification is the thickness (>0.4mm), and not the material alu-zinc. Please retract article with the necessary apologies.
We Shouldn't Even Be Using Metal
Author: G. K. Berko Posted: 2012-09-17 07:51:54 We shouldn't be using metal at all for our Roofing anymore. Other materials very common and cheaper materials could be used. We must shed this fallacious notion that only when you build with Cement Blocks and Metal Roofs that gives you some presige.
The bottom-line is having a well constructed, lasting House.
Long Live Ghana!!

LACK OF STRONG WORKING INSTITUTIONS
Author: ABU Posted: 2012-09-17 09:09:54 But you allowed the importations of substandard roofing sheets for decades superviced by our clueless and lazy leaders before complaining now.Fraudsters and cheats had long undue holidays to cheat innocent Ghanaian home owners.
Not true
Author: Mike Posted: 2012-09-17 14:55:46 People alu zinc also known as galvanized aluminum roofing sheet with less that 4mm has been around for many years. it suppose to last for more that 30 years with rust, unless it comes into contact with concrete or cement block.There is nothing wrong using this product for your house. This man is trying to promote his 4mm product and nothing less. Gone are the days when people use asbestos roofing sheet and it lasted for more that 5o years.
THAT'S WHY
Author: Asenso Posted: 2012-09-17 15:49:02 People get to the top and they forget or let me say STOP to read any further. Innovationis key to improving lives. Stop the bullshit Okoh.
Re: Stop using Alu-zinc for roofing sheet - Aluwor
Author: Sylvester Gamey Posted: 2012-09-18 06:41:34 So how does it get into the country in the first place? and why are you now saying this? and what material is ideal for roofing?
Agreed
Author: Sam Posted: 2012-09-18 09:54:43 The man is only warning us to be careful and dosent deserve the insults from certain circles. There are so many sizes in the market and he is saying that dont go for those less than 0.40mm. The comapanies will normally tell you the different sizes available - 0.35, 0.40, 0.45 ....0.50. He is saying that you suhould go for those above 0.40.

Re: Stop using Alu-zinc for roofing sheet - Aluwor
Author: E. Kwasi Okoh MD Aluworks Limited Posted: 2012-10-05 06:51:06 I wish I had written the article myself as it might have been more balanced. A summary of an interview is always dangerous because it represents what the summariser wishes to say and may not necessarily be the intentions of the interviewee.
Nevertheless I am very pleased that it is causing people to react. Some are very Ghanaian indeed quick to jump to insults instead of addressing the subject matter, and some very apt asking very scientific questions. I prefer to react to the latter type in an intellectual exercise that makes us all learn something from the debate.
One person was very right in opining that there are other forms of roofing that should be encouraged such as earthenware roofing tiles, which I agree with. But I was interviewed about Aluminium and Alu-zinc which has become the vogue in Ghana and I explained why people are lured to try Alu-Zinc.
Alu-zinc sheets are basically iron sheets clad with some aluminium in order to mimic the good properties of aluminium while giving strength to the sheet via the iron. Everyone knows that Aluminium is God endowed with a natural barrier to deep oxidation and therefore does not rust easily and is therefore very good for humid areas. Everyone also knows that iron sheets rust very easily and therefore used for roofing will not last long, hence the resort to the hybrid Alu-Zinc.
But a wolf clad in sheepskin is still a wolf.
The reality however is that aluminium is expensive, and far more expensive than iron. But it is the best and will last very long especially if colour coated as well.
The vogue is to use AluZinc because of price. But only few people know that they are basically buying an iron sheet, indeed there is very little aluminium. And the iron sheet will rust even if coated with colour. All it needs is a little scratch and rusting begins, whereas Aluminium if scratched immediately forms its own natural barrier to stop any rust. If it is thick enough then it will last very very long because it will need a very big scratch to cause a lot of trouble. I did mention the Standards Board ruling of 0.4mm minimum but that refers to Aluminium sheets. If Aluminium with all its natural properties requires a standard of not less that 0.4mm then one would expect the iron sheets to be far bigger than that to save it from rusting. But most AluZinc sheets are far far less, so the user is subject to far greater risk of eventual failure especially if it is used in a humid area such close to a water body (sea, lake, or river). A simple scratch (even for example to fix necessary roofing nails) once below the aluminium barrier sets off the rusting of the iron below and it is inexorable, just keeps rusting till is not longer good.
Yes it is cheap but it is very expensive in the long run as some people have found out to their chagrin. But this is a free country and people should have choice. People who decide to go into the AluZinc business are free to do so. Those who prefer to use AluZinc should be free to do so. Those who prefer to use pure aluminium should be free to do.
The most important point is that the choice must be an informed one so the decisions are properly made. People must know what they are getting into, hopefully before they get into it, not afterwards when they are having to expensively replace roofing sheets very often. There are pros and cons. Our view is that AluZinc is a bad proposition but we do understand why some people will go that way. Nevertheless it is our duty to get them to think again. No insults will change that.
