MBW 16 ft Magnesium Screed Bar

Description

Heat rises fast on summer parking lot pours when large continuous bays must get struck off before the mud flash-sets. The MBW 16 ft Magnesium Screed Bar spans one hundred ninety-two inches to level vast slabs in record time. Moving this sixteen-foot profile demands synchronized dual-worker pulling to stop blade skewing on stiff mixes.

Extruded virgin magnesium alloy gives this sixteen-foot bar extreme structural rigidity while holding bare weight to 22.4 lbs. The proprietary cross-section measures 192 inches in length, 4.75 inches across the bottom shoe, and 4 inches high. High-tensile magnesium metal resists concrete slurry adhesion and sheds aggregate buildup with ease. Internal structural ribs stop longitudinal twist under drag loads, transferring high-frequency exciter vibrations from the center mount out to both distal tips.

Key Features of MBW 17816

Commercial paving crews who buy MBW 17816 bars capture honest commercial screed bar pricing while eliminating cold joint seams across expansive floor installations.

• Sixteen-foot span allows fast single-pass strike-offs across large warehouse bays and parking aprons
• Extruded magnesium alloy construction reduces bare weight to twenty-two pounds for manageable crew handling
• Patented clamp mount attaches to ScreeDemon power heads in seconds without drilling bolt holes
• Curved forward blade profile curls excess aggregate forward to maintain uniform slab grade
• Wide bottom float surface densifies green paste to prepare concrete for immediate bull float work
• Enclosed hollow profile blocks wet concrete grout from getting inside the structural extrusion
• Precision machined bottom face meets strict floor flatness tolerances on large commercial flatwork
• Non-stick magnesium surface makes end-of-day washdown fast using standard jobsite hose pressure

Deflection Tolerances Bench Testing

Bench testing under 7,000 VPM vibratory loads records less than 0.048 inches of vertical deflection across the 192-inch length under a 110 lb static drag force. Transverse vibration transfer stays consistent, displaying an amplitude variance under 8 percent between center clamp and bar tips. In live 3-inch slump floor placements, the bar floated level without bucking or chatter, consolidating coarse aggregate while pulling a uniform cream layer across the sixteen-foot working width on every strike-off pass.

Field Usability Realities

Two finishers must coordinate pull pace on this sixteen-foot bar to prevent diagonal skewing across wide forms. Handle balance feels steady despite the broad span. Do not buy this 16-foot screed bar for small patio pours, residential basement rooms, or areas congested with vertical plumbing pipes.

• Rinse wet concrete paste from the mount track with fresh water right after each pour
• Inspect mount clamp bolt threads for paste contamination before attaching the power head
• Check total beam straightness with a string line every month to verify edge integrity
