Steel Truss Bridge vs. Concrete Box Girder Bridge – What’s the Difference? 🌉Choosing the right bridge structure is not just about aesthetics — it's a decision about strength, lifespan, and long-term value.Steel Truss Bridge (Truss Bridge)Structural weight: Light, suitable for small foundationsSpan: Can be very long (100–500 m)Strength: Strong – resists both compression and tension using triangular truss to distribute forcesMaterial cost: Medium to high (custom-made, almost no repairs needed)Construction complexity: High – assembled from many partsMaintenance: Requires rust protection and frequent inspection of rivets or boltsConcrete Box Girder BridgeStructural Weight: Heavier than truss bridges but lighter than traditional solid beam bridges, while still offering high strengthSpan Length: Medium to long spans (40–200 m)Strength: Handles compressive, tensile, and torsional forces effectivelyMaterial Cost: Moderate to high (especially when custom-fabricated)Construction Complexity: Moderate to high – requires special formworkMaintenance: Minimal, though internal maintenance can be challenging💡 Quick Summary:Truss Bridge: Light, suitable for extra-long spans, good for areas with limited foundations — but needs rust careBox Girder Concrete Bridge: Strong, durable, ideal for large-scale and national infrastructure — with low maintenance

In the construction of housing estates or condos at present, most of them have begun to use precast concrete widely instead of the traditional brick wall construction. Especially in the construction of large villages that require a large number of similar houses. Because it can help save resource costs in many aspects, such as time and manpower. It can also control standards better than brick construction. and today, Siam Steel Wire We will take a closer look at why precast concrete walls are popular among builders. And what should the residents do when using a house built from precast concrete? What is Precast Concrete? Precast Concrete is a part of the wall of a house or condo that will be precast in the factory before being moved for installation at the job site. This is different from the plastered brick wall that will be cast on site by the contractor. Precast Concrete has two main components, which are concrete texture and reinforcement with Wire Mesh or Cold Drawn Wire. Advantages of Precast Concrete1. Save construction time because the precast concrete wall can be cast and prepared in the factory during foundation assembly and then welded and assembled on-site.Unlike brick walls, construction only begins after the foundation has been assembled.2. Quality meets the same standard Because there is a casting from the factory, it does not depend on the skill of the mechanic or the weather at the job site.3. It requires much less labor than brick walls. because every part has been successfully cast from the factory and therefore can be placed in the house.4. High strength, so it can be used instead of columns or beams to support weight. because the structure consists of concrete and is also reinforced with Wire Mesh or Cold Drawn In addition, Siam Industrial Wire sells wire mesh and cold drawn from 4 mm to 12 mm, ready for use in precast concrete wall assembly, and it has met global standards, so you can be confident in its strength. more details: https://www.siw.co.th/en/product-detail/wire-mesh Caution1. Precast Concrete will not encounter cracks because the parts are cast in the same piece. But there may be a problem of water leakage along the edge of the wall joint if the connection is not tight enough.2. Wall drilling must be advised by engineers if it is supporting the weight of the structure.
