pic below is my neighbour contractor using small wood for truss, i suppose 2x4 inches. If want better, use 3x5 inches. The disadvantage of wood is termite and wood after years..it will bend.

Let me elaborate about this steel trust (kekuda). The steel trust is new to malaysia and to most contractors, not many contractor know how to install these steel trust. The difficulty in technique to assemble and joint between steel is the main reason, but if already expert or experience no problem. To the beginner, to install the steel they hv to assemble on the ground and lifted to the upper beam, lifted the frame is difficult job but with experience, they can install on the upper beam itself. The steel trust C type, to make is stronger, they must clamp together.

Are there strong enough to walk on it at least?

Yes, they are very very strong..when they are clamp together and joint compared to wood. As picture above. They do not bend over time as compared to wood, for wood you will see that your roof will 'melengkung or melendut' over time.

Do you need to ground the frame?
Certainly. You have ground it to upper beam.

Do this frame stand against the rust?
Yes, they are Galvanized to protect from rust

How is the cost compare to wood frame?
The overall cost is abit higher compared to wood, but it is one time investment, long lasting forever compared to wood.
The cost of per piece is not expensive around RM32 compared to wood but they must clamp together consisted of 2,3 piece to become one.
They are joint together using GI screw and if you were to buy loose, the screw cost RM0.08, but if per boxes more cheaper. Every joint between steel at least minimum 3 screw else afraid not strong enough.

hi bro,
attached below is my final product...now my house is cat proof house...i m using Y10 steel bar..i m not using hollow steel like kedai grill use that always rusted and need frequent paint. Cat cannot climb the steel bar. For the thief, the steel bar is not preventing the burglar but can slow down the attempted. I also seal the decoration wall. If i hv welding equipment i would put one horizontal bar all way to the back to strengthen the steel and structure. I hv eyeing for welding equipment but due to GST, i hv to postpone to buy the welding equipment.

Even i hv put the steel bar, few weeks ago, burglar tried to enter my house and bend the steel bar, luckly they did not break into my house as i woke up cause heard noise. So for me, luckly i hv the steel bar, to slow them down.

Now i put extra measure, I hv put also CCTV at beside my house wall.

the water outlet i use exiting and do not want to hack tile. The hand held shower, i just the Hitachi one supplied , do not intent to buy new one right now.

All my DIYs look easy but quite challenging for me (did it during my free times) for me it take times and sweat cause i m doing alone..haha. Most challlenging for me DIY is when you want to aligned or level alone while holding the parts. Maybe for other it is easy.
