PLATE GIRDER® System for Straight Walls

PLATE GIRDER Straight Walls
  • 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.


Available in widths of 2′ to 12′ (600 mm to 3600 mm) and lengths of 1′ to 20′ (300 mm to 6000 mm)
Combination Bias Corners (CBC) and Reverse CBC corners eliminate costly wood fills
Capable of achieving 64 ft2 (5.76 m2) of form area per tie
Withstands pour pressures up to 3800 lb/ft2 (190 kPa)
Provides an architectural concrete finish

Large Panel Wall Formwork

The EFCO PLATE GIRDER® forming system makes excellent wall forms, designed and built for setting and flying in large sections. Using EFCO’s Quick Bolt and Quick Pin, PLATE GIRDER panels can be assembled into gangs as large as your crane capacity. The system features modular versatility and produces an excellent concrete finish.





PLATE GIRDER® vs. a Typical Girder

Formwork Panels

The form panels of the EFCO PLATE GIRDER forming system work in a similar manner to a girder but include four important additional features for forming concrete.


The heavy gauge EFCO steel web does double duty, acting also as the form face sheet.


The EFCO corner bearing block in the PLATE GIRDER® form ensures 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.

Concrete Forming

The 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.

Modular Versatility

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


Question & Answer

How do you determine the pressure exerted on formwork when pouring concrete?

Concrete form pressure is determined based on the height of the 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 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”.

What are Engineered Formwork Systems?

Engineered formwork systems consist of prefabricated steel panels. The advantage of using these systems is to increase construction speed, 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. Please contact us for more information on what system would best fit your applications.

What is Formwork?

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

What is the difference between stripping the formwork and striking the formwork?

The removal of concrete formwork can be described as either stripping or striking.

Climbable Wall Formwork with A Z-RIB Design

The EFCO Z-RIB design allows you to climb the forms with appropriate safety equipment without needing a ladder. The Z-RIBS on 1-foot centers give you a structurally sound form with minimum deflection. Z-RIB design and placement help to keep the facesheet flat. Turn the Z-RIB leg up, and you have an easy hand and foothold to work from. The Z-RIB is also an excellent retainer for Rugged Tie assemblies and other accessories between pours and when flying forms.

Quality Concrete Finish

EFCO’s all-steel forms produce amazing high-quality concrete finishes. Where EFCO’s high-strength alloy steel form face sheets run clear to the edge of every form panel, you only get one single sharp line marking the form joint in the concrete. EFCO steel forms can deliver dimensionally accurate structures with superior concrete finishes.
