What Is an H20 Timber Beam? Sizes, Features and Uses

H20 timber beams are formwork beams used in slab, table-shoring, wall and column formwork systems. They can support a form-facing surface in slab work or form part of project-specific wall and column panels together with plywood and steel walers.

Where Are H20 Beams Used?

  • Table and slab formwork
  • H20 beam slab-formwork layouts
  • Single-sided and double-sided wall formwork
  • Column formwork panels
  • Vario-type timber-beam formwork
  • Project-specific formwork panels

H20 Beam Lengths

The current product range includes 145, 180, 215, 245, 265, 290, 330, 360, 390, 420, 450, 490 and 590 cm options. Beam length is selected together with panel dimensions, support points, joints and the overall formwork layout.

For the length list, see H20 Timber Beam Lengths: 145–590 cm.

H20 Beams in Table Shoring

In table-shoring systems, H20 beams can form part of the primary and secondary support arrangement below the slab-facing surface. Their exact spacing and arrangement depend on the formwork design.

H20 Vario Wall and Column Formwork

H20 beams, steel walers and plywood can be combined to create wall and column panels sized for the project. This arrangement is useful when the required panel dimensions do not match a standard modular steel-panel layout.

See H20 Vario Wall and Column Formwork for the system components.

H20 Formwork vs Modular Panel Formwork

Modular panel formwork uses prefabricated steel-framed panels. H20 timber-beam systems build the panel from H20 beams, steel walers, plywood and connection components. The suitable arrangement depends on project geometry and repetition.
