Product Introduction

Spec Sheet

Basic Description

Engineered for the toughest jobs,this drainage system is built to last where others fail. The polymer concrete channel withstands aggressive chemicals,thermal shock,and abrasion without degradation. It is capped with heavy-duty cast iron grating,renowned for its exceptional strength and ability to distribute massive point loads from forklifts,trucks,and machinery. This combination creates a drainage workhorse for factories,ports,and industrial facilities where downtime for repairs is not an option.

Core Strengths

Extreme Load-Bearing Capacity:

The cast iron grate is the industry standard for supporting the heaviest wheel loads (up to F900),ensuring safety and integrity under constant industrial traffic.

Superior Chemical & Abrasion Resistance:

The polymer concrete channel is impervious to oils,acids,solvents,and salts,while its smooth surface resists abrasion from debris and high-velocity water.

Long-Term Durability & Low Maintenance:

Both materials are exceptionally durable. The system requires minimal upkeep—no rust repair on the channel,and the heavy cast iron grate is built to last decades.

Excellent Fire Resistance:

Polymer concrete and cast iron are non-combustible materials,making this system ideal for areas with high fire safety requirements.

Stable,Rattle-Free Operation:

The significant weight of the cast iron grating ensures it sits securely,minimizing movement,vibration,and noise when vehicles pass over it.

Cost-Effective Lifecycle Value:

While the initial investment is robust,the near-zero maintenance and exceptionally long service life provide the lowest total cost of ownership for heavy-duty applications.

Application Scenario

Heavy industrial manufacturing plants and factory floors.

Logistics hubs,container terminals,and port loading areas.

Airport runways,taxiways,and maintenance aprons.

Fire truck access routes and emergency service areas.

Waste management facilities and recycling plants.

Any area subject to frequent heavy vehicle traffic and chemical exposure.

Installation and Maintenance

Installation

A solid,level concrete foundation is essential due to the system's weight.
Polymer concrete channel sections are set into place,bedded,and aligned.
The channels are fully encased in structural concrete for lateral support.
Heavy cast iron grating panels are placed onto the supporting ledges of the channel.
Final floor surfacing is completed up to the edges of the grating.

Maintenance

Regularly clear debris from the grating surface to maintain flow.
The polymer concrete channel can be cleaned with high-pressure water or standard industrial cleaners.
Inspect the cast iron grating for wear over very long periods; it is highly durable and typically requires no intervention.
Check the security of the grating panels periodically to ensure they remain properly seated.
