Beam with open U-shaped cross-section, constituting the strongest prefabricated element at present.

It came about in response to the increased capacity of means of transport and elevation offered on the market.

Makes it possible to adopt solutions comparable to on-site bridge constructions.

Use in isostatic and statically indeterminate set-ups with constant or variable depths.

Deck widths between 8.0 and 14.0 m.

Use in curved bridges with complex geometry in both the plan view and elevation view; radii from 50 to 200 m.

Used in creating continuous span sections with double supports at each end.

• Serving to create a closed cellular section.
• Constant depths from 0.80 to 2.20 m and up to 3.00 m for variable depth on piers.
• Great torsional stiffness.
• Lower flange widths of 2.30, 3.30 and 3.96 m.
• Powerful elements in creating decks 12.0 m wide with a single load-bearing element.

• Spans of 20-45 m in isostatic set-ups can be increased to 60 m with a cantilever and 80 m in statically indeterminate situations.
• The torsional stiffness is made use of with large overhanging slabs and in curved bridges.
• The interior space can be used as utility ducts (conduits).

Option of creating prestressed or post-tensioned pieces.

Cantilever support on 4 temporary or permanent points.

Double supports at each end.

Decks with variable depth slabs using permanent or temporary struts or a variable edge truss.

• Strength and resistance of the closed cellular section.
• More aesthetically appealing.
• In variable depth bridges, they offer advantages over centred arches or progressive cantilever structures.
• In statically indeterminate structures, they allow joint work to be done in the interior.
• Quick construction and assembly, as many square meters of deck can be covered with a single element.
