PERBEDAAN KUDA-KUDA BAJA DAN KAYU (THE DIFFERENCE OF STEEL TRUSSES VS TIMBER TRUSSES)

OBJECT COMPARISON

STEEL TRUSSES VS TIMBER TRUSSES

Function:

Roof trusses are used to carry and support the weight of the roof deck and any finish material used to cover the roof. This weight can be quite significant if clay or slate roof tiles are used, or it may be very light when used to support asphalt shingles or rolled roofing. The chords support the roof while the webs brace and stabilize the chords, helping to distribute the load across the entire truss to the bearing walls on either side.

Advantages and disadvantages:

Why WOOD trusses are worth it:

·         Less expensive than steel trusses.

·         Retain heat better than steel, which translates into lower energy consumption.

·         Ideal for the residential or small commercial markets.

What to watch out for:
Unless properly treated and regularly inspected, wood can suffer from water damage or become infested by termites or borer. With its natural flaws, wood can bend and break over time, causing structural damage which can be expensive to repair.

Why STEEL trusses are worth it:

·         They span further than wood trusses which make them useful for large areas.

·         Can be manufactured to exact standards.

·         Lightweight, easy to handle, and work with.

·         Not susceptible to termite or borer infestations.

·         While production can be energy-intensive, they can be recycled.

·         Can be used with various roofing materials, including concrete tiles, steel sheeting, pressed steel tiles, and fibre cement sheeting.

What to watch out for:
Steel roofing systems are more expensive, partly because they require more skilled labour. Steel does not retain heat as well as wood does and therefore uses more energy. Sound is more easily transmitted with steel. Steel is corrosive and can rust if not properly cared for and regularly inspected.

The difference:

Wood trusses

Wood trusses are labor intensive at the same time requiring more materials than a steel truss to do the same job. Hurricane clips and double headers with knee braces are necessary.  You must cut and mark each header . If you have ever done it you know how much time it can take. You must cut and mark the 2×4 purlin.

Steel trusses

Steel trusses no need for headers or knee bracing. No need for hurricane clips, trusses bolt directly to the post. Steel trusses are stronger and lighter than wood trusses. A single steel truss is more expensive than a single wooden truss.
