Concrete Formwork Clamp: High Durability 16MM Formwork Clamp Optimizes Formwork Installation Cost & Efficiency
As a core connecting accessory for modern steel frame formwork & Green formwork systems, our Concrete Formwork Clamp also named U-shaped formwork clamp has been verified by on-site construction engineers over 200+ high-rise and commercial building projects since 2018. Designed for interconnection of adjacent formwork panels, this 18MM diameter formwork clamp aligns and stiffens shutter boards effectively, widely matched with wall formwork and column formwork systems.
Our factory, specializing in formwork accessories for 16 years, provides ISO9001 certified formwork clamp with standardized production, real-site test data and full lifecycle cost calculation to help global construction contractors cut labor & material expense on formwork erection.

Cost & Performance Comparison: Concrete Formwork Clamp VS Traditional Wedge Pin + Bolt Fastening
We collected cost data from 3 typical residential high-rise projects (30-floor, total wall form area 12,000㎡) in Middle East & Southeast Asia construction sites to build this comparison table, all cost calculated based on full construction cycle (30 floors pouring):
| Comparison Dimension | Our U-Shaped Concrete Formwork Clamp | Traditional Wedge Pin + Bolt Fixing | Cost Saving Data |
|---|---|---|---|
| Unit Purchase Cost (FOB China) | $0.35/pc | Bolt+wedge set: $1.35/set | Initial purchase cost down 42.2% |
| Labor Installation Cost per 100㎡ | $32.5 | $61.8 | Labor expense cut 47.4% (fast mounting saves man-hour) |
| Average Reuse Times | 55 times | 12~15 times | Less replacement purchase in full project |
| Post-pour Concrete Repair Cost | $0/㎡ (tight connection no slurry leakage, smooth wall finish) | $2.8~3.5/㎡ (bolt hole filling & slurry leakage repair) | Zero hole-repair cost |
| Full Project Total Cost (12,000㎡) | $18,620 | $39,750 | Total project cost saved $21,130, cost reduction 53.1% |
Field Test Note from Project Engineer: When using our 18MM formwork clamp, formwork panel dislocation rate drops from 11.3% (traditional bolt fixing) to 1.8%, effectively avoiding form blowout risk during concrete vibration pouring.
Main Application Scenarios of Concrete Formwork Clamp
- Wall Formwork: Perfect matching for Green steel frame formwork, aluminum formwork and plywood shuttering wall system for residential & commercial building;
- Column Formwork: Ideal connector for square column & rectangular column formwork panel splicing, widely used in factory workshop, bridge pier column construction;
- Infrastructure Project: Suitable for culvert, basement retaining wall and other large-volume concrete pouring projects with frequent formwork turnover.
