Unlike Flange nestable corrugated steel pipe, Multi Plate is shipped to the site in curved plates and field assembled into its final shape by bolting. When spans exceed 3600mm, Multi Plate quickly becomes the best corrugated steel option. Without shipment limitations associated with large conventional pipe, combined with increased thicknesses and stiffer corrugations, Multi Plate expands the number of useful applications otherwise unattainable, and allows corrugated steel to be a viable alternative to the one or two options historically available in certain situations.
MULTI-PLATE structures provide designers of underpasses and bridges with a versatile method of construction and a long history of strength, durability, and economy. A variety of shapes and sizes ensures that MULTI-PLATE structures fit most applications. Ease of design, construction, and proven reliability make them the frequent choice of experienced engineers.
The plates are delivered to the job site and bolted together to form a MULTI-PLATE structure optimally suited for the project. Mulyi plate is available in full round, arch, pipe arch, horizontal and vertical ellipse, underpass-all in a wide range of sizes.
Culverts, storm sewer.
Span exceeds 3600mm.
MULTI-PLATE PIPE – ARCH
Culverts, storm sewer, and pedestrian underpass.
Limited headroom. Has hydraulic advantages at low flow levels.
MULTI-PLATE – ARCH
Bridge, and underpass.
“Low clearance, large waterway opening. Aesthetic shapes and open natural bottoms for environmentally-friendly crossings.”
MULTI-PLATE HORIZONTAL ELLIPSE
Larger Culverts, bridges.
“Low head room, good choice when poor foundations are encountered.”
SUPER-SPAN VERTICAL ELLIPSE
“Work well in higher cover applications.”
MULTI-PLATE – UNDER PASS
“Offers efficient shape for passage of pedestrians or livestock, vehicular traffic and bicycles with minimal buried invert”
MULTI-PLATE – HORSESHOE ARCH
Type HA : Large clearance Type EA : Large clearance and higher rise
