Our 20,000 m² foundry facility in Shijiazhuang, China
Looking for durable, heavy-duty sliding fence gate wheels that withstand constant use and extreme weather? As an import manager or brand owner, you need wheels that combine strength, low noise, and corrosion resistance – without endless lead times. Our factory, Shijiazhuang TJJ TRADE CO., LTD., has been casting high-performance sliding fence gate wheels for over 20 years, serving the US market with OEM/ODM flexibility, competitive MOQ (500 pieces), and delivery as fast as 15 days. Let's discuss how our foundry can become your reliable supply chain partner.
Why Standard Gate Wheels Fail – And How We Solve It
After years of supplying sliding fence gate wheels to US wholesalers and fence contractors, we've seen common complaints:
- Premature wear of nylon or plastic wheels under gates weighing over 500 lbs.
- Rust and jamming in humid or coastal environments.
- Noisy operation due to low-quality bearings or misaligned tracks.
- Limited size options that don't match existing gate rails.
- Inconsistent quality from multiple small suppliers, causing rework and complaints from end customers.
Our engineering team designed a range of sliding fence gate wheels specifically to address these failure points. Using proprietary cast iron and ductile iron alloys, precision CNC machining, and sealed stainless steel bearings, we deliver wheels that support loads from 300 kg up to 1,500 kg (660–3,300 lbs) with minimal rolling resistance. Each wheel is powder-coated or hot-dip galvanized per ASTM A123 to ensure 10+ years of outdoor service.

- Residential driveway gates – low noise, smooth glide for automatic openers.
- Commercial security fences – load-rated wheels for 10-ft tall welded mesh gates.
- Agricultural livestock pens – corrosion-resistant wheels in dairy and poultry farms.
- Industrial warehouse entrances – heavy-duty wheels for sliding fire doors.
Each application requires specific wheel durometer, bearing clearance, and track alignment. Our technical team can recommend the optimal combination based on your gate weight, track type, and environmental exposure.

What Our Buyers Say
Mark Johnson
Procurement Manager, FencePro USA (Texas)
“We tested TJJ’s sliding gate wheels against three Chinese suppliers. TJJ’s ductile iron wheels had the most consistent hardness and the bearing noise was 30% lower. Lead times have been spot-on for our JIT schedule. We now order 5,000 pieces every quarter.”
Linda Robinson

Brand Owner, Heritage Gate Products (California)
“As a brand owner, I need products that match my brand promise. TJJ helped me develop a custom wheel with my own color and laser-engraved logo. The samples arrived in 8 days and production QC reports were thorough. Highly recommended for OEM.”
Carlos Mendez
Sourcing Agent, Latin American Fence Distributors (Florida)
“I source a lot of hardware for Miami gate installers. TJJ’s prices are competitive, but the real win is the customer service. They helped me choose the right wheels for a luxury coastal project – no rust after 18 months. I keep coming back.”
James O'Connell
Import Manager, IronCraft Supplies (Canada)
“We tried to source wheels locally but costs were 40% higher. TJJ’s MOQ (500 pcs) allowed us to test with a small order. The quality matched our old supplier. Now we are scaling up. Very good communication.”
