Description
Concrete crews battle wavy slab finishes whenever weak strike-off boards sag under wet paste. The Wyco Magflo 10ft Screed Bar eliminates mid-span dip across medium industrial bays. Its magnesium alloy construction matches high-vibration eccentric heads without cracking at mount points. Remember that single power unit mounting concentrates vibratory forces near center clamp brackets during thick pours.
Cast and extruded from structural magnesium alloy, this bar withstands aggressive hydraulic paste while cutting total weight to 14 lbs. The proprietary Magflo profile features a 5-inch wide base and 4-inch vertical riser spanning 120 inches. Its high strength-to-weight ratio resists twist under heavy drag loads. Smooth radiused transitions shed wet mix instead of letting cement build up on structural flanges during extended consolidation passes.
Key Features of Wyco WS621420
Contractors who buy Wyco WS621420 bars gain commercial screed bar pricing advantages on flatwork jobs needing high production speed and minimal edge rework.
- Magnesium alloy construction sheds concrete buildup while resisting fatigue fractures caused by continuous eccentric vibrator rotation
- Curved leading edge rolls surplus aggregate forward to keep screed lines level across wide concrete slabs
- Broad trailing foot compacts wet paste to produce consistent surface seal prior to bull floating
- Universal mount bracket interface clamps onto standard single power units without tedious custom bracket drilling
- Rigid structural profile prevents center bowing when operators drag dense low-slump mix uphill on slope pours
- Reinforced clamp bed disperses mechanical shock across the beam center to protect the main extrusion profile
- Lightweight magnesium frame allows single operator guidance on parking pads without inducing excessive lumbar strain
Vibratory Amplitude Bench Results
Bench tests using an eccentric power unit turning at 8,500 VPM demonstrate linear wave transmission across the full 120-inch profile. Mid-span vertical flex measures under 0.025 inches when loaded with 80 lbs of live drag resistance. Mechanical vibratory forces distribute evenly to outer tips, displaying less than 5 percent drop in strike amplitude. In 4-inch slump slab trials, the bar floated clean over coarse aggregate without chatter marks or transverse wave washboards across the concrete face.
Field Handling Service Realities
Ergonomics stay well balanced on slab pulls, letting operators guide the beam with controlled hand pressure. Direct vibration isolation keeps harsh buzz out of steering handles. Do not buy this 10-foot screed bar for tight trench footings or structural wall forms where boxed clearances pinch bar ends.
- Wash the magnesium profile down with water before concrete paste takes initial set on outer edges
- Torque power unit clamp bolts to factory specifications to prevent wallowing out the mount holes
- Inspect the strike face every month with a precision straightedge to verify bottom edge flatness
Factory Warranty Parts Breakdown
Wyco backs this screed bar with a 1-Year limited manufacturer warranty against material flaws and premature structural cracking. The factory shipment contains the bare 10-foot Magflo screed blade, heavy-duty single unit mounting hardware, protective plastic tip caps, and detailed setup guidance sheets for fast field deployment.
