PAIN POINTS

Ordinary Wheels Create Hidden Costs Every Day

8 problems IRONMAX is designed specifically to solve for you

01

Cracked / Deformed Wheels

Ordinary nylon or plastic wheels can't really carry the load and deform under heavy weight

 02

Seized / Stiff Bearings

Hard to push, takes a lot of effort, staff get back pain and productivity drops

 03

Damaged Epoxy Floors

Black rubber wheels leave dirty marks, or steel wheels scratch the factory floor, leading to expensive repairs

 04

Bent Steel Brackets

Brackets that are too thin bend at the slightest impact until the wheel stops turning

 05

Peeling Treads

Low-quality treads separate from the steel core after a while, so wheels must be replaced often

 06

Disruptive Noise

Loud, rattling carts break concentration on the factory floor

 07

Not Oil Resistant

Exposure to factory oil or chemicals makes them crumble, lasting less than a month

 08

Out of Stock

Waiting 3–7 days for parts stalls work and costs business opportunities

FAQ

Frequently Asked Questions

How much weight can IRONMAX caster wheels carry?

The 6-inch model carries 350 kg per wheel, or up to 1,400 kg per set, and the 4-inch model carries 250 kg per wheel, or up to 1,000 kg per set, thanks to the 5.5 mm thick cast-iron core.

Do cast-iron-core PU wheels leave marks on factory floors?

No. The PU tread doesn't damage epoxy floors the way black rubber wheels do, and it resists factory oils and chemicals well.

When will I receive my order?

We hold stock in Thailand ready to ship immediately, with express delivery within 24 hours — no waiting 3–7 days as with other suppliers.

What is the starting price?

Single wheels start from 390 THB each (4-inch rigid), and set promotions start from 1,690 THB per set, including 7% VAT, with free shipping when you buy a set.

Which caster types are available?

There are 3 types in both 4-inch and 6-inch sizes: rigid (fixed), swivel and brake.

Which model should I use for a 1-tonne trolley?

Use the 6-inch model in a set of 4 wheels, rated up to 1,400 kg per set — enough for 1-tonne work with a safety factor already included. We recommend a set with brake casters so the cart can be locked in place.

Can PU wheels be used on epoxy floors?

Yes, very well. The PU tread leaves no marks and doesn't scratch epoxy floors, making it ideal for food, pharmaceutical and electronics factories that need clean floors — unlike black rubber wheels, which leave marks, and steel/nylon wheels, which scratch the floor.

Do you ship internationally?

Yes. We ship worldwide — both PU caster wheels and custom trolley/steel fabrication to your drawings. International shipping is charged at cost based on weight and destination. Message us on LINE @IRONMAX-THAILAND or call +66 64-241-9787 for a quotation.
