MBW Screedemon 18′ Screed Bar Magnesium

Description

Center sag and blade chatter ruin floor flatness specifications across wide commercial concrete pours. The MBW Screedemon 18 Foot Screed Bar maintains true strike-off plane over eighteen-foot wide spans. Extruded magnesium conducts high-frequency vibration deep into paste. Pulling this eighteen-foot bar through stiff low-slump concrete demands two finishers on pull ropes working in steady unison.

Genuine extruded magnesium alloy forms the structural box-triangular profile, providing rigid resistance against vertical flex while remaining lighter than aluminum boards. The blade profile features a rounded strike nose that rolls aggregate forward while floating cream smooth. Unboxed blade weight measures 29 lbs, spanning 216 inches with a 4.75 by 4.25 inch cross section that mounts directly to Screedemon powerheads.

Key Features of MBW 17818

Commercial concrete contractors and paving crews bolt this eighteen-foot blade to Screedemon power units for warehouse slabs, airport aprons, and parking decks. Inquire about equipment distributor pricing to buy MBW 17818 screed bars for high-production commercial flatwork.

• Extruded magnesium alloy delivers superior vibration resonance to consolidate aggregate.
• Eighteen-foot span eliminates cold joint seams across wide commercial pour bays.
• Contoured front edge rolls excess concrete forward to minimize manual raking labor.
• Flat rear float surface seals the slab face and brings rich cement paste to top.
• Lightweight twenty-nine-pound magnesium profile reduces drag fatigue on long continuous pulls.
• Fast clamp bracket attachment secures blade to Screedemon powerheads without drill modifications.
• Non-corrosive metal construction resists chemical degradation from concrete admixtures.
• Rigid internal triangular chambers prevent blade twist during heavy aggregate drag.

Magnesium Resonance Load Deflection Metrics

Center-span deflection measures under 0.075 inches across the eighteen-foot span under dead weight. When coupled to a Screedemon power unit running at 7,500 VPM, vibration transfer measures 0.038 inches amplitude at the center mount and 0.029 inches at the outer tips. Magnesium dampens acoustic ring while transferring kinetic energy deep into six-inch slab pours. The profile consolidates low-slump concrete mixes down to two-inch slumps without aggregate segregation. Extrusion straightness holds within 0.035 inches along the entire 216-inch bottom edge.

Commercial Strike Operator Service Realities

At eighteen feet wide, this screed requires two finishers operating pull ropes in steady tandem along perimeter form rails. The lightweight magnesium construction lets two workers lift and reposition the blade after each pass. Do not buy this eighteen-foot blade for small residential patios or narrow sidewalk pours. Commercial flatwork contractors striking off wide industrial warehouse bays gain massive labor savings from this blade.

• Hose down the magnesium blade with clean water before concrete paste hardens.
• Inspect the bottom float edge for stone gouges and burrs before each placement.
• Check mounting bracket hardware tightness before starting the screed motor.
