The engineering philosophy behind our support truss focuses strictly on minimizing on-site friction while maximizing load-bearing efficiency. Every component is crafted to solve the real-world challenges faced by construction crews, ensuring that your infrastructure projects are completed ahead of schedule and under budget.
Frictionless Assembly: Precision-machined pinholes and standardized connectors eliminate the need for on-site modifications, allowing pieces to slide together with satisfying ease and secure firmly.
Extreme Weather Readiness: The specialized surface treatments repel moisture and resist the abrasive forces of wind-blown sand, ensuring the structural integrity remains pristine even in coastal or desert environments.
Optimized Logistics: By keeping individual component weights manageable, we drastically reduce the dependency on massive, expensive heavy-lifting equipment, cutting down transportation and rental costs.
Versatile Terrain Adaptation: Whether spanning a deep ravine or a wide, shallow riverbed, the modular nature of the truss allows for seamless length and width adjustments on the fly.
Uncompromised Safety Margins: Engineered to exceed standard load requirements, providing total peace of mind when heavy commercial vehicles or emergency equipment traverse the span.
Exposure to relentless moisture, road salts, and industrial chemicals demands a metallurgical defense system that never sleeps. Our support trusses are forged from premium high-strength, low-alloy structural steel, specifically grades like Q345B and Q355B. This exceptional core material provides the immense tensile strength required to support heavy dynamic loads without yielding or warping over time.
To shield this robust core, we employ a rigorous hot-dip galvanizing or inorganic zinc-rich anti-corrosion coating process. The steel is submerged into molten zinc, creating a metallurgical bond that seals every microscopic crevice. This results in a sleek, visually flawless finish that acts as an impenetrable barrier against rust and decay. This dual-layer approach ensures high load-bearing capacity in the most extreme, hostile environments, dramatically extending the operational lifespan of both temporary and permanent bridge installations, and drastically reducing your long-term maintenance expenditures.

Advanced hot-dip galvanizing creates an impenetrable, long-lasting rust barrier.
Inorganic zinc-rich coatings available for specialized environmental resistance.
Significantly extends the lifecycle of the infrastructure, lowering total cost of ownership.
Installation Method Recommendation
Time is the most expensive commodity on any construction site. Delays cost money, disrupt supply chains, and extend road closures. Our 450 Support Truss tackles this pain point directly through an intelligent, highly standardized modular design. Pre-fabricated in standard 3-meter sections, the components are engineered to be compact and optimally weighted, allowing for effortless transportation via standard commercial trucks rather than specialized oversized load carriers.
Once on site, the magic of our modular system truly shines. With single transom pieces weighing no more than 1 ton, the assembly process requires only small-scale cranes or, in certain scenarios, manual assistance. We empower your crews with comprehensive blueprints, step-by-step video tutorials, and expert remote or on-site guidance. This streamlined workflow means a fully functional, heavy-duty bridge can be erected and opened to traffic in a matter of days, not months, slashing labor costs and minimizing regional disruption.
Standardized 3-meter prefabricated sections for predictable, rapid assembly.
Optimized weight distribution (transoms ≤ 1 ton) eliminates the need for massive cranes.
Easily transportable in standard shipping containers and flatbed trucks.
Reduces project completion times from months to mere days.

What is the recommended installation procedure for the bridge?
First of all, an experienced construction team should be assigned to undertake the erection of the bridge. We have studied the drawings of the erection site and surrounding area, and conclude that the installation site is spacious and flat, so we recommend the installation procedure as follows:
1. Assemble the bilateral bailey panels to two whole construction, including the lower chord reinforced, horizontal bracing, vertical bracing, male and female end post. Every assembling unit is mainly composed by 27 pieces of bailey panel. Meanwhile, the bridge bearings are installed on the abutment. Note that: check the length of the single whole bailey truss and the distance between the bolts of the two side of the river, if not fit, adjust the bolts.
2. Use suitable lorry-mounted crane to lift the two assembling truss unit and place them on the two side abutments. The single combined truss unit is weight about 11tons and 27.4 m length.
3. Install the transom, please refer the video. For the weight of one piece of transom is about not more than 1 ton, so it need a small crane. In order to increase the stability of the structure during the erection, the nearest transom and the farthest transom, as far as possible according to the capacity of the crane, should be installed first, then for other transoms between them.
4. Install the sway bracing, then pave the first row in width direction of bridge decking on the transoms, including the side and middle bridge decking. Meanwhile, install the upper chord reinforced to strengthen the structure, then the crane could move onto the bridge decking to install the following ahead transoms, similar ways like upper procedure to be perform.
5. The rest can be done in the same manner.
6. Final, install the upper chord reinforced, curb, gap plate, handrail, connective plate and handrail column.
