 Product Title(H1)

6 Inch Rigid Caster – 304 Stainless Steel Fork with PU-on-Aluminum-Core Wheel, 400kg Load Capacity (Model: C01-S-1PU-650)

 Short Description

A corrosion-proof fixed caster​ engineered for the harshest working conditions. Model C01-S-1PU-650 Rigid​ combines a 304 stainless steel fork, PU-on-aluminum-core wheel, and non-swivel rigid bracket​ to deliver straight-line stability in seafood processing plants, fishing docks, cold storage warehouses, outdoor job sites, and chemical-exposed environments—anywhere ordinary steel casters would rust and fail within months.

 Full Product Description

Straight-Line Strength. Zero Drift. Zero Rust.

The C01-S-1PU-650 Rigid​ is built for one job done perfectly—moving heavy loads in a straight line, reliably, without deviation, in environments that destroy conventional casters. Saltwater spray on fishing boats, sub-zero cold rooms, acidic seafood wash-downs, scorching outdoor summers—this caster handles it all.

The 304 stainless steel fork and bracket​ form an impenetrable barrier against rust, oxidation, and chemical corrosion. Unlike galvanized or painted steel that chips, flakes, and rusts within weeks of marine exposure, this caster maintains its structural integrity and clean appearance year after year.

The polyurethane tread on an aluminum core​ provides the perfect balance: non-marking, quiet operation​ on delicate floors, with the thermal stability​ to handle temperature swings from -30 °C freezers to +60 °C outdoor heat​ without cracking, softening, or deforming. The fixed rigid bracket​ eliminates sideways drift—essential for towed carts on slippery fish-processing floors and tilted dock surfaces.

Typically paired with two swivel casters on a four-wheel cart, the rigid pair provides directional stability while the swivels handle steering. As a factory-direct caster manufacturer, we deliver consistent quality at competitive pricing.

 Key Features & Benefits

Technical Specifications

Recommended Applications

 1. Seafood Processing & Fishing Industry

• Fish processing plants​ – tuna, salmon, shrimp, crab handling lines

• Fishing vessels & trawlers​ – deck carts exposed to constant saltwater spray

• Seafood cold storage​ – moving fish totes between -25 °C freezers and processing floors

• Aquaculture farms​ – shrimp, oyster, salmon farm equipment carts

• Fish markets & auction halls​ – daily wash-downs with chlorinated water

• Lobster & crab holding tanks​ – brine splash and humidity exposure

 2. Warehouses & Cold Chain Logistics

• Cold storage warehouses​ (-18 °C to -30 °C) – pallet dollies, mobile racking

• Distribution centers​ – high-throughput picking carts in humid environments

• Food distribution hubs​ – USDA/FDA-regulated material handling

• Beverage & dairy cold rooms​ – milk, beer, juice keg transport

• Frozen food processing​ – straight-line carts between freezer and packaging

•  3. Outdoor & Marine Working Environments

• Boat docks & marinas​ – equipment carts on piers and jetties

• Offshore platforms​ – corrosion-resistant tool trolleys

• Outdoor construction sites​ – material carts exposed to rain, mud, and UV

• Seaside resorts & coastal facilities​ – maintenance carts in salt-air environments

• Harbor cargo handling​ – outdoor rolling platforms in tidal zones

• Ferry terminals & shipyards​ – heavy-duty carts on salt-spray-exposed decks

4. High-Corrosion & Chemical Environments

• Chemical processing plants​ – acid/base handling carts

• Pharmaceutical labs​ – sterile, corrosion-proof mobile workstations

• Water treatment facilities​ – chlorine and chemical exposure

• Electroplating & metal finishing shops​ – acid mist and chemical splash zones

• Bleach & detergent manufacturing​ – caustic soda and chlorine exposure

• Battery recycling plants​ – acid spill resistance

 5. Temperature-Difference Environments

• Blast freezers (-30 °C) to ambient (+20 °C)​ – thermal shock resistant

• Hot wash-down areas (+60 °C steam)​ to cold storage transitions

• Outdoor summer heat to air-conditioned facilities​ – no cracking or softening

• Foundries & heat-treatment shops​ – intermittent high-heat exposure

• Baking & food ovens (cool side)​ – warm environment material handling

 Why 304 Stainless Steel + Aluminum Core Wins in Corrosive Environments

 Temperature Resistance Explained

Note: For continuous exposure above +60 °C, we recommend our high-temp phenolic wheel series.

 Why Choose Rigid for Seafood & Marine?

Not Recommended For

• Continuous exposure above +80 °C​ – choose phenolic or steel wheels

• Extreme heavy loads over 400 kg​ – choose our 600 kg galvanized series

• Deep mud, gravel, or sand​ – pneumatic tires are more suitable

• Non-corrosive dry indoor use only​ – galvanized version offers better value

• Speeds exceeding 4–6 km/h​ – designed for controlled manual movement

• Tight turning radius applications​ – rigid cannot turn; use swivel instead

 FAQ

Q: Will this really not rust on a fishing boat?​

A: Yes. The 304 stainless steel fork and bracket are marine-grade. We've salt-spray tested to 500+ hours (ASTM B117 standard) with zero corrosion. Trusted by tuna longliners and crab boats in the North Pacific.

Q: Can the PU wheel handle being frozen at -25 °C and then rolled out to a +20 °C floor?​

A: Absolutely. The polyurethane tread remains flexible at low temperatures, and the aluminum core prevents thermal expansion issues. Cold-chain logistics companies choose this caster for exactly this reason.

Q: Is the entire bracket stainless steel or just the surface?​

A: The entire fork, bracket, and top plate are solid 304 stainless steel—5.5 mm thick. No plating, no coating. It will not chip, peel, or rust from the inside out.

Q: Can I pair this with swivel casters on the same cart?​

A: Yes. The industry standard is 2 Rigid (rear) + 2 Swivel (front) for optimal control. All four share the same top plate dimensions for easy mixing.

Q: What is the MOQ?​

A: Standard MOQ applies. Contact us for exact numbers based on your region and configuration mix.
