Solutions For Pulp and Paper Industry
For over 50 years we have been providing top quality reliable products to the pulp and paper industry.
Below are just a few examples of our Solutions for Paper manufacturing.


DURAGRATE® Molded Grating

DURAGRATE molded fiberglass grating is significantly lighter in weight than metallic gratings and the high resin content (65) provides long, virtually maintenance-free performance. A higher safety factor is achieved by designing in a higher glass content at the bottom of the grating for greater tensile strength.

DURAGRATE molded fiberglass grating is:

• Corrosion Resistant
• Easy To Fabricate
• Fire Retardant Duragrate
• Impact Resistant
• Low in Maintenance
• Low in Conductivity
• Lightweight
• Bidirectional Load Bearing
• Easy To Install
• Cost Effective
• Uniform in Appearance
• Concave non-slip walking surface


EchoSwitch™ Ultrasonic Switches Flowline EchoSwitch

• Programmable target calibration for relay setup.
• Accurate and reliable level control from 0.5 to 26.2 feet.
• Available in maximum ranges of 4, 10, 16.4, and 26.2 feet.
• Three internal 1A relays for local alarm, pump or valve control.
• All plastic construction with PVDF transducer and ABS housing.
• Standard 3m cable provided for easy target calibration.

Plastic-Lined-Steel Piping

Plastic lined steelWhen corrosive piping applications require the chemical resistance of plastic and the strength of metal, think plastic-lined-steel piping. It's available in corrosion resistant PTFE, PFA, Polypropylene, and PVDF locked in liners and pipe sizes to fit your specific needs. Harrington can fabricate spool pieces to your exact specifications.
