Only Industrial Corporation (OIK) is established since
1976. The founder John Tsai has over 40 years of experience in developing
rollers and components related to windows and doors.
OIK has worldwide markets,
ranging from America, Europe, Australia, New Zealand and South East Asia
regions. Our main markets are Japan and America, this further endorses the quality of our products. |
 |
|
We started by manufacturing
nylon, polyacetal, stainless steel, steel rollers, and now have extended our products to adjustable roller sets, hinges, and other related parts to doors
and windows.
Rollers are the hearts of
the doors and windows. We focus especially on those that are used in the
showers, sliding, screen and pocket doors, windows, and filing cabinets. | |

|
We’re constantly improving our rollers to make
installations easier for window and door manufacturers.
Please send us your
drawings/pictures or your requirements and we’d be very honored to give you
our best quotations with the best qualities. |
