Product Overview

The Concrete Wall Formwork System is a modular lightweight-steel panel system engineered for demanding concrete forming. Each panel is constructed from 1.5 mm Zn-Al-Mg coated Q700 high-strength steel, with 2 mm edge plates, roll-formed into U-shaped profiles with hollow stiffening ribs through a 32-process roll-forming line.

Laser welding replaces conventional welding - minimal heat-affected zones prevent thermal deformation, seams are flat and smooth, and the process adapts well to complex structural joints. Surface color consistency is controlled to Delta E ≤ 1.5, achieving the tolerances required for fair-faced concrete without secondary plastering.

Key Benefits

1. Q700 steel substrate (>700 MPa yield) outperforms conventional formwork steels and aluminum alloys in strength

2. ZAM coating delivers 1500+ hours salt-spray resistance with cut-edge self-healing - 3–5× conventional galvanizing

3. Lightweight at ~25 kg/m², with hollow stiffening ribs maintaining rigidity without excess weight

4. 300+ reuse cycles with proper handling; 100% recyclable steel with scrap residual value

5. Seven width specifications cover 100–400 mm for flexible project layouts

Higher Substrate Strength for Demanding Pours

With a yield strength above 700 MPa, the Q700 substrate significantly exceeds conventional formwork steels and aluminum alloys (~240 MPa), providing greater lateral pressure capacity and structural security for high-rise and heavy-duty applications.

Superior Corrosion Resistance with Self-Healing Edges

The Zn-Al-Mg coating achieves 1500+ hours in salt-spray testing - approximately 3–5× the performance of conventional galvanized steel. When panels are cut or drilled, the exposed edge forms a protective film that prevents rust from spreading inward - a decisive advantage over hundreds of reuse cycles.

Lightweight Without Compromising Rigidity

At approximately 25 kg/m², the hollow stiffening-rib design delivers the rigidity needed for fair-faced concrete while reducing handling labor compared to traditional heavy steel panels.

Frequently Asked Questions

Lorem ipsum dolor sit amet,consectetur.

What does "Q700" mean in this formwork system?

"Q700" refers to the high-strength steel substrate used in the panels, with yield strength above 700 MPa. It indicates a structural grade significantly stronger than conventional formwork steels. We recommend stating "high-strength steel substrate with yield strength above 700 MPa" rather than citing a specific standard number until factory verification is complete.

What are the advantages of Zn-Al-Mg (ZAM) coating over conventional galvanizing?

The Zn-Al-Mg coating delivers approximately 3–5× the corrosion resistance of conventional galvanized steel, with 1500+ hours in salt-spray testing. A key advantage is cut-edge self-healing: when panels are cut or drilled, the exposed edge naturally forms a protective film, preventing rust propagation over hundreds of handling cycles.

How many reuse cycles can this system deliver?

The system is designed for 300+ reuse cycles with proper handling, cleaning, and storage. Actual performance depends on concrete mix, pour pressure, release agent practices, and site handling. Factory-verified data is recommended before publishing a specific guarantee.

What panel widths are available?

Seven width specifications cover the 100–400 mm range. Exact dimensions and weights per specification are pending factory confirmation - please send your drawings for a tailored recommendation.

How does ZAM Q700 steel formwork compare to aluminum formwork for high-rise projects?

Both suit high-rise construction with different trade-offs. ZAM Q700 offers higher substrate strength (>700 MPa vs. aluminum ~240 MPa), superior corrosion resistance with self-healing cut edges, and 100% steel recyclability with scrap value. Aluminum is lighter and well-established for high-rise repetition. The choice depends on project-specific cycle counts, concrete specifications, and total cost-of-ownership analysis.
