How we check our alignment couplers
Each of alignment formwork clamps goes through full quality checks. Our workers will check dimensions, welding strength and surface coating. Only qualified formwork clamps can be packed. We can supply inspection records for you.
On‑site installation steps For Alignment Formwork Clamp

1. Let two steel formwork panels close to each other.
2. Hook both claw ends of the G‑type coupler onto the frame ribs of the two panels.
3. Slide the adjustable wedge bar to match your real gap width.
4. Strike the wedge head with a hammer until the coupler sits tight, panels stay level and no movement.
5. Check again before pouring concrete. Make sure claws don't slip off panel frames.
6. After concrete hardens, tap the wedge loose for quick removal. The coupler can be collected and reused for next jobs.
Important note: Clean concrete mud, sand and debris from wedge teeth before reuse.
