Benefits of Portable Steel Bridge
Time – One of the most significant differences between prefabricated and on-site bridge construction is construction time. Portable Steel Bridges offer significantly faster installation compared to on-site construction, bringing several advantages in different aspects.
Less susceptible to weather delays – Since components of a Portable Steel Bridge are manufactured off-site, the installation process is much shorter, making it less affected by weather conditions.
Quality control – Portable Steel Bridges bring advantages because they are manufactured in a controlled factory environment, ensuring more consistent quality control compared to on-site construction.
Energy efficiency and eco-friendliness – On-site bridge construction typically generates more waste due to material inefficiency. Portable Steel Bridges do not suffer from this issue, as any excess materials can be easily recycled for future projects.
Financial benefits – One of the biggest advantages of Portable Steel Bridges is cost efficiency. Compared to on-site construction, prefabricated solutions can often deliver better overall economic performance.
Safety – The construction process for Portable Steel Bridges is also safer than on-site construction. This is because there are fewer risks in an indoor, controlled manufacturing environment compared to an outdoor site, which may be affected by changing weather, soil conditions, and external hazards.
Cleaning & Debris Removal: Power wash truss members , bridge seats, and bearings to remove sand, salt, and debris.
Structural Inspection: Check for loose/missing bolts, cracked welds, and paint failure.
Corrosion Protection: Clean, prime, and repaint rusted steel, focusing on areas with high moisture, such as the bottom chord.
Weathering Steel
Weathering steel can be the perfect option in most cases because in can span up to 200’ without intermediate supports and provides a nearly maintenance free / natural looking finish.
Galvanized Steel
Galvanized is also a great choice for corrosive environments. Aluminum’s span is good up to 110’ whereas galvanized steel can go up to 200.’ Galvanized is also a better alternative to aluminum if the bridge needs to be rated for heavy vehicles (such as emergency vehicles).
Painted Steel
For aesthetics and/or additional corrosion protection, epoxy coatings are commonly used as well on these structures.
