Introduction
Q700 steel formwork is made from high-strength alloy steel for casting walls, columns, slabs, beams, and other structural concrete. The Q700 designation tells you the steel grade – minimum yield and tensile strength of 700 MPa.
The panels are 1.5mm thick, formed by stamping and laser welding. They come with a zinc-aluminum-magnesium (Zn-Al-Mg) coating that stops rust. Panel depth is 65mm. The modular design lets you set up different shapes without much fuss.
This system sits between traditional steel and aluminium. It performs like aluminium but costs about a third as much, and it is light enough that you do not need a crane for most handling. With 300+ reuses, the numbers work out well for repetitive floor construction.
Advantages
Weight
Panels weigh 19.6 to 24.7kg per square metre, depending on the configuration. Single panels run from 10kg up to 58kg. Most are manageable by two workers – no crane needed for routine handling.
Cost
Material cost is roughly one-third of aluminium. With 300-plus reuses, the cost per pour is lower than timber and aluminium over the project life. The Zn-Al-Mg coating outlasts conventional galvanised steel by two to three times.
Corrosion resistance
The Zn-Al-Mg coating, about 80μm thick, stands up to moisture, rain, and concrete slurry. It works in coastal areas, humid conditions, and outdoor storage – places where ordinary steel would rust quickly.
Reuse cycles
You get 300-plus uses with normal site care. Some operations report up to 1,000 cycles. Spread the cost over that many pours and it becomes hard to beat.
Concrete finish
The 1.5mm steel face gives you smooth, clean concrete. Often good enough to leave bare – no plastering needed.
01
Turnaround
Columns and shear walls come off the form in 24 hours. Slabs take 36 hours. Floor cycles run 4 to 5 days – comparable to aluminium.
02
Compatibility
Works with Ring Lock, Crab (500X), Kwikstage, and independent prop systems. Also connects with aluminium formwork panels.
03
Shipping
Flat-pack design cuts shipping volume by up to 60% compared to traditional steel formwork. That saves real money on international freight.
04
Recyclability
Steel is 100% recyclable when you are done with it.

Applied Range
Q700 steel formwork covers most concrete work:
·High-rise residential and commercial towers
·Standard floor and repetitive slab work
·Super high-rise – works with Ring Lock, Crab, and Kwikstage shoring
·Industrial plants and factories
·Bridges and tunnels – coating handles wet and outdoor conditions
·Public infrastructure – airports, stations, hospitals, stadiums
·Basements and non-standard floors – including pipe galleries
·Complex shapes – round, curved, and irregular forms
Good for jobs where aluminium is too expensive but you still want light handling and quality concrete finish.

Competitive Edge
Cost
About one-third the price of aluminium. 300-plus reuses. Zn-Al-Mg coating lasts two to three times longer than conventional galvanised steel. Fewer replacements.
Weight
19.6–24.7kg/m² – similar to aluminium. Handled by workers, not cranes. Saves on transport too.
Rust protection
Zn-Al-Mg coating holds up in coastal areas, wet conditions, and outdoor storage. No rust issues.
Speed
24-36 hour demoulding. 4-5 day floor cycles. Matches aluminium on turnaround.

A: It is the steel grade – yield and tensile strength of at least 700 MPa.
Q: How much load can it handle?
A: Over 60 kN/m² concrete pressure. Fine for high-rise and heavy-load work.
Q: How many uses can I get?
A: 300-plus with normal care. Some users report up to 1,000 cycles.
Q: How heavy is it?
A: 19.6–24.7kg per square metre. Single panels from 10kg to 58kg. Two workers handle most pieces.
Q: How does it compare to aluminium?
A: Costs about one-third of aluminium. Similar weight and performance. Same demoulding times and concrete finish.
