PLATE GIRDER® Self-Spanning Formwork

PLATE GIRDER Self-Spanning
  • Telescoping Push-Pull Pipe Brace

    The EFCO Telescoping Push-Pull Pipe Brace allows easy alignment and plumbing of the form set-up. The EFCO Pipe Brace Shoe is used to securely hold the set-up down and is designed to give easy access to the anchoring bolt.

  • Lifting Eyes

    Lifting Eyes bolt directly onto the form and allow cycling of equipment by crane.

  • Top Yoke

    The EFCO Rugged Taper Tie or Top Yoke is all that’s required to tie the top of the form set-up on a 12'-0" wall.

  • Bottom yoke

    Bottom yoke ties the opposing panels allowing for the bulkhead and soffits to be secure.

  • Combination Bias Corners

    Inside corners and pilasters are easily formed using EFCO’S Combination Bias Corner (CBC) form. This standard form eliminates job-built fillers and or take-up panels in the middle of walls. For tight, enclosed situations such as inside cores, use the Reverse CBC in combination with the CBC to relieve a corner before cycling.

  • Manual Retractable Stripping Corner

    EFCO’S Manual Retractable Stripping Corner creates a fast corner connection for shaft and core construction.

  • Outside Angle Corner

    EFCO’S Outside Angle Corner connects panels on outside corners.

Self-Spanning Concrete Formwork

EFCO’s experience, engineering, and forming technology have developed the PLATE GIRDER®forming system. This is with many of your forming needs in mind, including bridges, stadiums, marine work, and power plants, together with wall forming and elevator and shaft forming for high-rise construction. The system is here to deliver the best value and lowest in-place concrete costs. The PLATE GIRDER forming system will meet your needs for strong, durable, and yet versatile concrete forming. The form panels of the EFCO PLATE GIRDER forming system work in a similar manner to a girder but with four important additional features for forming concrete. The heavy gauge EFCO steel web does double duty, acting also as the form face sheet.

Large Gang Walls

The EFCO corner bearing block in the PLATE GIRDER® form insures the transfer of the flange forces between the individual modular forms. This provides EFCO’s PLATE GIRDER forming system with its unique self-spanning characteristics which enable the contractor to pour aerial concrete without expensive and time-consuming inter-span shoring.


  • Modular
  • All-steel face sheet provides consistent finish
  • Self-spanning
  • Fewer ties mean increased productivity
  • Large panels and picks
  • Rugged taper ties

Formwork can refer to an engineered system that is used to efficiently form and support poured concrete.

Engineered formwork systems consist of prefabricated steel panels. The advantage of using these systems are to increase the speed of construction, increased durability and longevity, and the ability to span formwork across supports. EFCO provides a wide variety of products including HAND-E-FORM, EFCO LITE, PLATE GIRDER, and SUPER PLATE GIRDER. For more information on what system would best fit your applications, please contact us.

All-steel ribs of the PLATE GIRDER® system form panels serve not only as web stiffeners but also as beams to transfer the horizontal pressures of the liquid concrete from the form face plate to the form panel top and bottom flanges. 

The PLATE GIRDER forming system comes in modular lengths and widths that can easily be connected giving flexibility for changing job conditions. 

Concrete form pressure is determined based on the height of concrete being placed. The height of concrete times the density of concrete will determine the pressure exerted on the forms at a given depth. EFCO forms, such as PLATE GIRDER, are rated for a maximum allowable pressure to be exerted from the concrete. As concrete transitions from a flowable liquid mix to a solid, the concrete will no longer continue to build pressure with depth. Monitoring this transition point is important to ensure the allowable pressure on the forms isn’t exceeded. For more information, see “A Practical Guide to Concrete Pressure & Formwork
