Stainless Drainage Cover

>> Product Introduction

Stainless drainage covers are durable, corrosion-resistant grates designed for high-traffic and harsh environments, made from 304 or 316 stainless steel. They provide long-lasting performance in areas prone to moisture, chemicals, or extreme weather.

Key Features:

High load capacity (up to Class D400, 40-ton axle loads)

Slip-resistant surfaces (serrated or grit-coated)

Rust-proof & chemical-resistant (ideal for coastal/industrial use)

Hygienic & easy to clean (suitable for food/pharma facilities)

Applications:

Roadside drainage

Industrial plants

Marine & coastal areas

Food processing zones

Keywords: stainless steel drainage grate, corrosion-proof trench cover, high-load stainless grating

>> Product Advantage

1. Superior Corrosion Resistance

Crafted from 316 stainless steel (Mo-enhanced), our covers withstand saltwater, acids, and chlorides for 20+ years. Passes 5,000-hour salt spray tests (ASTM B117) – ideal for coastal plants and de-icing zones.

Keywords: marine-grade drainage cover, chemical-resistant trench grate, saltwater-proof stainless grating

2. Heavy-Duty Load Capacity

Rated EN124 Class D400 (40-ton axle loads) with 6-10mm thick crossbars. Third-party tested for 2 million fatigue cycles – handles airport tugs and container loaders.

Keywords: high-load stainless grate, industrial trench cover, D400-rated drainage system

3. Advanced Safety Design

Laser-cut serrations (4mm depth, 0.85+ friction coefficient)

DIN 51130 R12 slip-resistance for fuel stations

Anti-lift locking lugs prevent dislodgement

Keywords: non-slip trench cover, OSHA-compliant drainage, vandal-proof stainless grating

4. Hygienic & Low Maintenance

Electropolished finish (Ra≤0.8μm) meets FDA/EC1935 standards. Resists bacterial growth – steam-cleanable at 150°C for food/pharma facilities.

Keywords: sanitary drainage cover, hygienic trench grate, cleanroom-compatible stainless

>> Product Uses

1. Coastal & Marine Infrastructure

Ideal for ports, piers, and seawalls, our 316 stainless steel covers resist saltwater corrosion indefinitely. Slotted designs prevent marine growth clogging while withstanding 40-ton loaders.

Keywords: marine drainage grates, saltwater-proof trench covers, port stormwater systems

2. Food & Beverage Processing

Electropolished 304SS (Ra≤0.8μm) meets FDA/EC1935 hygiene standards. Steam-cleanable surfaces prevent bacterial buildup in meat/poultry plants.

Keywords: sanitary drainage covers, food-grade trench grates, hygienic floor channels

3. Chemical & Pharmaceutical Plants

316L grade withstands acids, solvents, and CIP fluids. Bolt-down designs contain spills, while 5mm slots block tool drops.

Keywords: chemical-resistant trench covers, pharma drainage grates, explosion-proof grating

4. High-Traffic Urban Areas

Class D400-rated covers handle bus lanes and taxi ranks. Anti-slip grit (R12) and low-noise rubber seals enhance safety.

Keywords: municipal drainage covers, pedestrian trench grates, urban stormwater systems

5. Fuel Stations & Oil Refineries

Non-sparking 316SS complies with ATEX Zone 1. Epoxy-coated versions resist hydrocarbon corrosion.

Keywords: explosion-proof drainage covers, fuel farm trench grates, oil-resistant grating

6. Airport & Transportation Hubs

Ultra-flat designs (3mm lip) prevent luggage wheel damage. 40-ton capacity supports aircraft tugs.

Keywords: airport trench covers, heavy-duty drainage grates, aviation ground systems

>> Product Operate Guide

• Surface Preparation

Ensure concrete channels are level (±3mm tolerance). Apply non-shrink grout under frames for 100% support.

• Secure Installation

Use 316 stainless fasteners (M12 minimum) to prevent galvanic corrosion. For traffic areas, opt for recessed frames with epoxy anchoring.

• Load Management

Align heavy vehicle wheels parallel to bars – never exceed rated class (A15-F900). Avoid point impacts from steel tools.

• Cleaning Protocol

For food/pharma: steam-clean ≤150°C weekly. Industrial sites: Pressure wash with pH-neutral detergents.

• Inspection

Check quarterly for:

Debris blockage (clear slots)

Fastener tightness (re-torque to 50Nm)

Coating wear (repassivate if pitting occurs)

>> FAQ

1. What’s the difference between 304 and 316 stainless steel?

316 contains 2-3% molybdenum for superior corrosion resistance in saltwater/chemical environments. 304 is cost-effective for mild conditions like urban drainage.

2. How do I prevent debris clogging?

Choose 5-10mm slot widths for high-flow areas. Install sediment baskets underneath for easy cleaning in leafy zones.

3. Are these covers slippery when wet?

No. Laser-cut serrations (0.85μ COF) or grit coatings (R10-R12) exceed DIN 51130 slip-resistance standards.

4. Can I customize the slot pattern?

Yes. We provide CNC-cut slots (5-20mm) with ±0.5mm tolerance. Submit CAD files for complex drainage layouts.

5. What maintenance is required?

Annual inspection for slot blockages. Repassivate if scratches occur using nitric acid gel (for 316 grade).
