Product List
Non-woven Roll
The Non-Woven Roll is manufactured by layering and pressing Non-Woven material onto a Roll Shaft. The material composition of the Non-Woven fabric and the pressing method of the roll can be tailored to meet the specific requirements of various industries and applications.
KRST supplies Non-Woven Rolls to a diverse range of industries in Korea, including steel, automotive, metal, film, and paper, through strategic partnerships with TOHO-YOGYO (Japan), NCCM (USA), and its own in-house fabric production developed through advanced proprietary technology.
Product Features

|---|---|---|---|
| High Friction Coefficient | Non-Tex Roll: 0.28 (Dry), 0.24 (Wet) Rubber Roll: 0.16 (Dry), 0.08 (Wet) |
Prevents strip slippage, enabling high line speeds. | Tension Bridle, Pinch, Support, Steering, Guide, Deflector Roll |
| High Shearing Stress | Non-Tex Roll: 1,280 kg/cm² Rubber Roll: 600–700 kg/cm² |
Reduces roll edge damage, extends roll lifespan, and lowers maintenance costs. | Support, Feeder, Table, Wringer, Loop Rolls |
| Superior Wringer Effect | Absorbs and expels the solution during each roll revolution for perfect wringer effects. | Achieves precise wringing and squeezing on both strip surfaces and edges. | Wringer, Squeeze, Pinch, Wiper Rolls |
| Clean Strip Surface (No Marks or Defects) | Foreign particles are embedded between stacked disks, ensuring no dents, scratches, rubber powder, oil stains, or carbon deposits. | Results in a perfectly clean strip surface. | Wringer, Squeeze, Table, Support, Pinch Rolls |
| Excellent Chemical and Alkali Resistance | Outstanding chemical resistance (acid and alkali resistant). Non-Tex material composition can be customized based on application. | Extends roll life and enhances roll performance due to superior chemical resistance. | Various rolls requiring high chemical resistance. |
| Various Usage | Highly adaptable to a range of industrial applications. | Provides effective solutions for existing line challenges. | Various Usage |

Application Line
1Steel, Metal
Wringer, Squeeze Roll
- Post-pickling Rinse Outgoing Wringer Roll, Pre-treatment Outgoing Wringer Roll
- Water Quenching Outgoing Wringer Roll, SPM Post-process Wringer Roll
- Post-plating Processing Outgoing Wringer Roll
- Excellent moisture removal effect, minimizes water retention on edge areas
- 3 to 10 times longer lifespan compared to existing rolls (Rubber, Urethane)
Oil Wiper Roll
- Rolling Mill (CRM, ZRM, TRM) Oil Wiper Roll
- Achieves perfect wiping of rolling oil
- No residual oil on strip edges after coiling
- Increases productivity and reduces costs by reducing coil misalignment rates
- Prevents oil splashing around the rolling mill, enhancing safety
Tension Bridle Roll
- The high friction coefficient ensures excellent adhesion to the strip, preventing slip even at speeds of approximately 1,600 mpm.
- Exceptional durability due to high shear stress.
- Friction coefficient comparison:
Non-Tex Roll: 0.28 (Dry), 0.24 (Wet)
Rubber & Urethane Roll: 0.16 (Dry), 0.08 (Wet) - Shear stress comparison:
Non-Tex Roll: 1,280 kg/cm²
Rubber & Urethane Roll: 600–700 kg/cm²
Oiler Roll
- Roll designed to apply oil onto the surface of the strip
- By adjusting the disk insertion density, rolls with lower surface hardness can be produced
- The surface hardness can be fine-tuned based on the desired oil application volume
2Automotive
- Non-Tex Rolls (Pinch Roll, Wringer Roll, Feeder Roll) used in the washing units of OEM manufacturers
- Utilization of OW90H Non-Tex fabric through a technical partnership with Toho Yogyo (Japan)
