Hi bro,

In my earlier post , i hv mention about this metal truss...hope you can find in my post. However , i just tell summary.. Trend now is metal truss for the main reason of anti termite and these metal truss long lasting. Compare to wood roof truss as i mention before. Wood roof truss is not 'long lasting'..over time it will sag or the wood will bend causing causing leaking and safety.

There are 2 type of metal truss sell nowaday, Normal GI metal truss and blue color metal truss. It was informed that the blue type is corrosive resistance higher than white type.  Not many contractor or indon know how to install these metal truss. For any unexperience person, it is difficult to install these metal truss. There are 2 methods to assemble these metal truss, First Assemble on the ground then lift up to the top/roof (refer to my post earlier and picture) and secondly assembly right on the top ( this method is for experience worker/contractor). Connection between these truss steel are using screw and Jointer (L or V shape etc). If i can recall the cost for screw per piece is 8 sen. The more screw u you the stronger your structure, min 3 screw per joint.

There are 2 main component of these metal truss, the 'C' Section and the V section (batten).

C section Metal truss (if i can recall the GI type cost about without GST RM32 per piece , blue type RM42 per piece)

The batten metal (where u put the roof tile) (if i can recall about without GST RM16 per piece) :

One of the sample my roof truss, i hv many pic but tired to post..

[attachmentid=4478686]

You can have aluminium foil install on top of the roof truss or you can install aluminium zink on top of the truss (aluminium zink more expensive but advantage stronger and can prevent thief  ).

From the quotation you received, u can PM me if whether expensive or not. TQ...

gd luck bro.

very lastly...there is very very small draw back of this metal truss if not properly installed (many do not know about this) ..as it is metal , when hot or cold, the metal will stretch and shrink , when you join together , it will cause sound especially at hot whether...haha...i think you cannot avoid this horror sound of metal ...however there is solution for this if you do not want to hear it....only myself know...haha
gd luck bro.

same concept with wood and metal truss..u can step and walk on it..u can design ur path if you like..
if not properly install...its knocking sound bro...   you will never know it until your roof finish install...for me no problem. metal truss is way better than wood..

if i m a contractor..i will 'drop my water face'..if i reno house using wood truss..hahaha... ..just joking...

hi bro,

this is the secret i hv not reveal yet...
