Reproduction in H0 scale (1:87) of a complete span of 5 H-beams and street level slab of a classic concrete road bridge for urban or service roads. Suitable for roads with a carriageway width of 3.00 meters in each direction, without pavements.

A piece of considerable size and complexity, perfectly reproduced and sized thanks to FDM 3D printing technology with cement gray like PLA material, it is supplied in a single piece, ready to be combined with the pillars and the terminal abutment with master code 1004, obtaining a viaduct of the desired length.

Finish of the bioPLA material

Assembly
Where assembly between the pieces is required, we recommend using cyanoacrylate glue for a quick and resistant fixing. We recommend lightly sanding the parts to be glued.

Sanding
To mitigate the streaking effect, you can roughen with 180/240 grit sandpaper and continue with finer grits, up to 1000 for the final sanding. It is recommended to moisten the sandpaper or wet the piece with cold water to avoid overheating the surface too much, as the PLA material could knead at high temperatures.
The use of power tools for sanding is not recommended.

Painting
Use acrylic products of the desired color with a matt finish (for cement, gray RAL 7035). To obtain a more uniform surface, the use of an airbrush or spray can is recommended. You can apply multiple coats until you are satisfied, leave to dry between coats.
