Walers and Strongbacks
|
The strength of the panel design makes a waler necessary for alignment only, it is not a structural part of the formwork. Only one row of 2" x 4" walers on each tier of panels is required, with a variety of time and material saving attachment options available to increase your productivity.

Scaffold Hardware
|
Scaffold Bracket The Scaffold Bracket comes with a wedge and cable attachment for quick assembly. Note: Do not use Scaffold Brackets to support cantilevered concrete soffit forms, or for temporary storage of construction equipment or material.

Steel-Ply panels and fillers are constructed from a rugged steel frame. The side rail of the form is rolled exclusively for Symons and has a minimum yield stress of 55,000 psi. Crossmembers have a minimum yield stress of 60,000 psi and are located at one foot centers on all panels and fillers. Symons special ½" High Density Overlay (HDO) or birch plywood provides a smooth finish. Each piece is edge sealed with polyurethane to repel moisture and prevent delamination. With proper care, contractors can expect up to 200 reuses before plywood replacement. Steel-Ply requires little training because it has no top or bottom, left or right, and can be used vertically or horizontally. Dado slots at crossmembers simplify tie placement. Slots for hardware attachment are located between crossmembers. All Steel-Ply components combine to provide a 1000 psf rated system with a predictable safety factor over the service life of the form. Sizes Steel-Ply is also available in metric sizes. Panel and filler heights range from 60 cm to 240 cm in 30 cm increments. Panel widths are 60 cm and filler widths range from 10 cm to 55 cm in 5 cm increments. Steel Fillers The 2" Steel Filler has connecting slots at 2" O.C. It is used to "step" forms in 2" increments. This steel filler reduces the need to build up under forms when step footings or changing wall elevations occur. Filler Angles These Filler Angles are recommended where reinforcing steel, pipes, or other penetrations must protrude through the form face. |

The Steel-Ply system consists of more than 80 standard panel and filler sizes . Wedge bolts connect panels, fillers and ties in one simple operation, making formwork erection and removal quick and easy. |

| You have the option of ordering your Steel-Ply concrete forms with Quick-Hook Handles™. The 5,000 lb. capacity of the integral Quick Hook Handle gives workers convenient handholds and attachment points for safety belts. It meets the Occupational Safety and Health Administration (OSHA) requirements for personal fall protection (Subpart M). |

Connecting Hardware
|
For productive setting and stripping of forms, Symons offers a variety of co nnecting hardware.
Wedge Bolts For typical walls, form connecting Wedge Bolts are only required at standard tie connection positions. Additional Wedge Bolts are utilized at other positions for attachment of walers, scaffold brackets or other accessory components.

Ties
|
Symons has the largest selection of standard and special ties in the industry. Wire ties and flat ties are used for standard Steel-Ply tie spacing, and reusable load-gathering She-Bolt and Taper Ties are used for wider tie spacing. S-Panel Ties X-Flat Ties
Threaded Ties S-Base Tie |
Corners
|
Inside and Outside Corners Standard Inside Corners have a face dimension of 4" x 4" or 6" x 6". Each Inside Corner is manufactured with reinforcing straps to maintain 90°. Dadoes are placed 12" On Center (O.C.) for tie connection and slots are placed half-way between the dadoes at 12" O.C. for connecting hardware. Bay Corners The Inside Bay Corner has a 3" x 3" face dimension, and the Outside Bay Corner has a 7" x 7" face dimension. Ties connect at adjoining panel joints to complete this forming detail. Bay Corners can also be used horizontally to form wall haunches and "Y" walls. Hinged Corners In most wall applications, Inside Hinged Corners are used opposite Outside Hinged Corners. Always insert connecting Wedge Bolts towards the adjoining panels so that the angle will not be restricted. Corners should always be adequately waled, braced and blocked as required. |

You may not believe that forming with Steel-Ply is cheaper and easier than forming with plywood and 2 x 4's... and you may not want to take our word for it... so, prove it to yourself! |
Residential Foundations and Other Handset Forming
|
Attached Hardware An attached Hardware Kit is also available for contractors who wish to retrofit Steel-Ply® panels and fillers they already own.
|
![]() Beam Pocket for Foundation Void |
Beam Pocket The Beam Pocket is a reusable tapered steel boxout that leaves a void pocket at the top of the foundation wall for steel or wooden beams. The standard 6 x 8 x 4 deep size comes with a handle for easy carrying and removal. |
|
Transition Fillers The Resi-Ply/Steel-Ply Transition Filler allows you to use the Steel-Ply versatility for forming curved walls and to simplify complicated forming applications. The Steel-Ply/Silver Transition Filler allows you to use existing or rented forms for below grade walls and Symons Silver for exposed walls where concrete finish is important. |
|
Form Extension Bracket
|
|
Cantilever Bracket The Cantilever Bracket is used to suspend a form on the opposite side of the wall. This allows different elevations at the bottom of forms so that a base slab can be monolithically poured with the wall. Maximum capacity is 700 lbs. Maximum spacing is not to exceed panel length when forms are horizontal, and must not exceed 8'-0" when panels are vertical. |
| Brick Ledge Bracket The Brick Ledge Bracket is used to form brick ledges and support various framed boxouts. The bracket is attached to panels or fillers with Wedge Bolts. The bracket spans the wider side of a 2" x 4" piece of lumber to create the offset needed. |
|
Bulkhead Forming Bulkhead bars can be used for forming bulkheads in walls 4" to 24" wide. Standard Wedge Bolts attach the bars to the siderails of panels and fillers. Bulkheads can also be formed by using Outside Corners and a panel or filler.
|
|
| Haunch Forming Haunch Brackets provide an ideal way to form haunches or corbels, without any additional lumber support. The Haunch Bracket connects easily with Steel-Ply® panels and is designed to support ¾" plywood. Slots make securing walers a simple operation. |
|
Footing Corner Bracket Attachment
|
Footing Corner Bracket Stake Plates are then positioned along the top edge of the Steel-Ply for Steel Stakes. The Stake Plates are typically located midway between Steel-Ply crossmembers and endrails to provide access for a stake puller. |
The most popular engineered, reusable, factory-built concrete forming system in use today is manufactured by Symons. Steel-Ply is designed for maximum versatility. It can be used to form virtually any kind of concrete pedestal, culvert, haunch or stoop as well as straight, curved, battered or "Y" walls. Practically any dimension can be formed by combining panel or filler sizes and using them vertically or horizontally. |
