Stop Stripping. Start Building.
Traditional concrete forming is a two step process. First you build the form, then you tear it down. Expand-A-Form changes the game. Our expanded metal “Stay In Place” (SIP) forms are designed to be integrated directly into your structure. Once you pour, you are done.
Why Choose Expand-A-Form?
-
Zero Stripping Costs: Save hours of labor by eliminating the need to remove, clean, and transport heavy wood forms.
-
2x Faster Installation: Lightweight and easy to fabricate on site. If you can use a circular saw or tin snips, then you can install Expand-A-Form.
-
Superior Concrete Bond: The unique expanded mesh creates a high quality mechanical bond and allows for easy visual inspection during the pour to ensure no honeycombing.
-
American Made Quality: It is manufactured centrally in St. Louis, MO. Thus, this tends for fast shipping and reliable U.S. steel standards.
Versatile Solutions for Every Pour
Expand-A-Form is the professional choice for complex or hard to reach forming areas where traditional wood is impractical.
Ideal Applications:
-
Bulkheads & Construction Joints: It simplifies rebar penetration. Just punch the bar through the mesh.
-
Grade Beams & Pile Caps: It speeds up below-grade forming where stripping is difficult.
-
Blindside Walls: It is the perfect solution for tight-access forming against existing structures.
-
Column & Beam Pockets: Easily custom cut to fit any geometric requirement.
