The "Aluminum Alloy Structural Floor Slab" is a pedestrian bridge renovation product that can be installed manually. It is one-fifth the weight of a deck plate floor slab, allowing for manual installation and transportation. The 100-year floor slab reduces maintenance costs and does not require replacement. It can be installed manually in small sections in a short time. Aluminum, with its lightweight and excellent weather resistance, solves problems even under difficult renovation conditions depending on the installation environment. You can trust us with challenging installation areas. 【Construction Flow (Partial)】 ■ Temporary enclosure installation ■ Removal of existing structures ■ Beam inspection and measurement ■ On-site painting (sanding and priming) ■ Installation of mounting brackets *For more details, please download the PDF or feel free to contact us.

The "Compact Bridge" is a simple bridge that adds a sidewalk to small bridges that do not have sidewalks over residential roads and school routes. It is a construction method used for widening sidewalks with a span of about 10 meters and a sidewalk width of about 2.0 meters, where an "aluminum deck" is placed on brackets attached to the bridge abutments. By performing tasks such as railing installation and paving at the factory, it reduces on-site labor and allows for immediate passage. Please feel free to contact us when you need our services. 【Features】 ■ Improved safety for small bridges ■ No need for large-scale construction ■ Reduced construction work and significantly shortened construction time and costs ■ Manufacturing and assembly are done at the factory, then transported to the site by truck *For more details, please download the PDF or feel free to contact us.
