Heavy Duty Trench Drain System - 39.37" - ACO S300K

$653.00


FREE SHIPPING
SKU S300K

Engineered for the toughest industrial and commercial sites, the Heavy Duty Trench Drain System combines a polymer concrete channel with integral ductile iron rails to deliver exceptional durability, chemical resistance, and long service life.

Key Highlights

  • Extreme load capacity: Rated to EN 1433 Class F (proof loads up to 200,000 lb).

  • Efficient hydraulics: Built-in 0.5% slope and V-shaped invert accelerate flow and help self-clean the channel.

  • Secure grating: PowerLok® boltless locking with anti-shunt lugs prevents grate movement and rattling.

  • Modular flexibility: Mix sloped and neutral channels in multiple lengths; knock-out outlets simplify connections.

  • Faster installation: Numbered channels and optional installation aids streamline layout, grading, and setup.

Heavy Duty Trench Drain System – Class F, 12″ Channel, PowerLok® Boltless Grates

Complete guide to a heavy-duty trench drain system with a polymer concrete channel and integral ductile iron rails. Rated to EN 1433 Class F (up to 200,000 lb proof load), with built-in 0.5% slope, V-shaped invert, PowerLok® boltless locking, and modular sloped/neutral channels with knock-out outlets. Includes installation tips and a real-world case study.

Heavy Duty Trench Drain System: Complete Guide (with Case Study)

Overview in plain English: This is a rugged trench drain built for forklifts, fire trucks, and constant traffic. The polymer concrete channel and ductile iron rails take a beating, while the 0.5% built-in slope and V-shaped invert move water fast. Grates lock in without bolts using PowerLok®, so inspections and cleaning are quick.

Why Choose a Heavy Duty Trench Drain?

  • Extreme load capacity: Rated to EN 1433 Class F (up to ~200,000 lb proof load) for heavy axle traffic.
  • Efficient hydraulics: 0.5% built-in slope and V-invert promote rapid flow and scouring action (less debris buildup).
  • Long service life: Polymer concrete resists chemicals and freeze-thaw; integral ductile iron rails protect edges under wheels.
  • Secure grates, faster access: PowerLok® boltless locking with anti-shunt lugs prevents grate rattle and uplift.
  • Modular flexibility: Mix sloped and neutral channel sections; use knock-out outlets for easy tie-ins.
  • Install friendly: Numbered channels and optional aids streamline layout, grading, and sequencing.
Best-fit environments: loading docks, distribution yards, manufacturing floors, ports, bus depots, fire/EMS bays, airport aprons, and heavy-duty parking.

Design Checklist (Engineer’s Quick Notes)

  • Catchment & rainfall: Contributing area, storm intensity, and inflow points.
  • Traffic mix: Trailers, forklifts, fire apparatus—spec Class F where impacts occur.
  • Grate type: Ductile iron for heavy impacts; heel-proof/ADA where foot traffic exists.
  • Outlets & access: Position knock-outs and service intervals for fast cleaning.
  • Concrete haunch: Size for subgrade, frost, and wheel-load transfer.

Installation & Maintenance (Step-by-Step)

  1. Plan & benchmark: Confirm outlet elevations and fall; map channel sequence by numbers.
  2. Excavate & base: Prepare trench width/depth; compact subgrade and bedding per spec.
  3. Set channels: Place sloped/neutral modules to line and grade; verify continuous fall.
  4. Join & seal: Connect outlets; seal joints; check invert alignment and watertightness.
  5. Haunch & slab: Install concrete haunch to required dimensions; allow proper cure.
  6. Install grates: Engage PowerLok®; confirm anti-shunt lugs are seated.
  7. Commission: Water test; remove debris; record access points for O&M.

Routine care: Schedule periodic debris removal via access points. Boltless locking speeds service and reduces downtime compared to bolted systems.

Case Study: Loading Dock Modernization Cuts Downtime

Site: Regional distribution terminal • Challenge: Ponding and failing trench grates near dock doors caused slip hazards and frequent repairs.

Constraints & Issues

  • Trailer and forklift traffic imposed heavy, multidirectional loads (turning and braking).
  • Bolted grates loosened and rattled; missing hardware increased risk.
  • Tight maintenance windows—dock operations could not afford long closures.

Solution

  • Installed a Heavy Duty Trench Drain System (12″ channel) with PowerLok® boltless locking and anti-shunt lugs.
  • Used a mix of sloped and neutral channels to tie into existing storm laterals without regrading the slab.
  • Specified reinforced concrete haunching and planned access points for efficient cleaning.

Results

  • Better uptime: Boltless access cut service time; no more lost bolts or rattling grates.
  • Faster storm recovery: V-invert + 0.5% slope minimized standing water after peak events.
  • Lower lifecycle cost: Durable rails and polymer concrete reduced repairs and replacements.

Frequently Asked Questions

Is this system suitable for very heavy vehicles?

Yes. With EN 1433 Class F capability and ductile-iron edge protection, it handles heavy axle loads from fire apparatus, tractor-trailers, and GSE equipment.

How does the boltless locking improve maintenance?

PowerLok® provides secure, tool-light grate removal. Anti-shunt lugs resist lateral movement and rattle, so inspections and cleaning take less time.

Can I combine sloped and neutral channels?

Absolutely. Use sloped sections to establish fall, then neutral pieces to meet exact inverts or extend runs while keeping outlet elevations.
