History

ISRS Certification for North Salt Lake, UT, ELyria, OH, Gravenhurst, Canada, PlantS

Representing more than 35 years of accumulated best practice experience in safety and sustainability management, the ISRS certification procedure reviews the entire management system including risk management, environmental aspects, the health and wellness of employees, and an overall assessment of management as a whole process. According to DNV-GL’s website, “ISRS is a world-leading system used to assess, improve and demonstrate the health of an organization’s business processes. Using ISRS gives organizations and their stakeholders’ peace of mind that their operations are safe and sustainable.”

ISRS Certification for Clinton, TN, Plant

Early in 2013, Dura-Line embarked on a safety initiative through DNV-GL called ISRS. Early in 2017, our sites began working on establishing the foundation for ISRS Certification. ISRS Edition 7 was chosen since it is the most applicable edition to general industry while including the evaluation of not only safety systems but environmental, health, and security. Level 6 certification was chosen as a target to match the level of risk in our processes.

Introduced FuturePath Figure-8 Self-Support Aerial

With FuturePath Figure-8 Self-Support Aerial, seven MicroDucts are bundled under one sheath with a messenger, so there's no need to spend time and money for strand and lash. Dura-Line’s Figure-8 standard self-support duct has been in use around the country for more than 30 years and with the launch of FuturePath Figure-8 Self-Support Aerial option allows for a flexible, expandable network with dedicated, easily identifiable pathways for system upgrades, redundancy, and future capacity. Not only is it a safer option for linemen because it cleans up the pole, it keeps fiber networks secure and easy to access. As an on-going revenue source, some customers have chosen to lease out the extra pathways.

Orbia Acquires Dura-Line Business

Dura-Line was acquired by Orbia. The Dura-Line business group is part of a community of companies working together to tackle some of the world’s most complex challenges, including improving communication infrastructure. All employees are bound by a common purpose: To Advance Life Around the World.

Total of 20 manufacturing facilities worldwide

Introduced new formulation SuperSILICORE

Dura-Line’s proprietary lubrication coextruded with the conduit products that aids in adding fiber to a conduit by reducing the friction; thereby increasing installation distances and decreasing time spent during construction. This efficiency usually results in significant savings

TL 9000 Certification

Dura-Line received certification as a TL 9000 rated manufacturer. In 1998 QuEST Forum (a group of service providers, suppliers, and liaisons dedicated to Telecom industry) developed the TL 9000 Quality Management System to meet the supply chain quality requirements of the worldwide telecommunications industry.

Introduced Enterprise FuturePath

Introduced Locatable MicroDucts

Perfect for drops in Fiber To The Home (FTTH) applications, MicroDucts Locatable include a location wire for easy identification in the ground. 

Introduced Figure-8 Aerial MicroDuct

Introduced FuturePathFlex, FuturePath Fire Retardant Products, and CIC MicroDucts

Dura-Line has built a long-standing reputation based on its continuous innovation. The ability to meet the needs of customers with specialty products elevated Dura-Line as an industry leader year after year.

Introduced LSZH duct and fire retardant MicroDucts

Introduced FuturePath bundled MicroDucts

MicroDucts bundled under one sheath are called FuturePath and provide multiple ducts in one structure for future expansion of networks. It can be installed with the same tools and equipment as standard conduit.

Introduced MicroDucts

MicroTechnology is a term given to given to smaller conduits and fiber used in Inside and Outside Plant Construction (ISP and OSP). MicroDucts were developed as a solution to house fiber cables that were smaller in size, but still carried significant capacity. Today, MicroCables range from 6 to 432-fiber counts. The glass fibers are the same type as those used in traditional fiber cables, only the cable design has been altered to reduce the diameter of the cable sheath and support system. 

Introduced Figure-8 Aerial duct

Standard Figure-8 Aerial conduit is designed with an Extra High Strength (EHS) flooded galvanized support strand for one-step aerial placement. The conduit is manufactured with carbon black and antioxidants for maximum UV protection. Figure-8 can be installed with standard aerial installation practices.

Introduced FIREJACKET Plenum-Rated

First ISO 9001 Certification

Dura-Line becomes an ISO-9001 rated company achieving the certification of the international standards and specific requirements for a quality management system, demonstrating the ability to consistently provide products that meet customer and regulatory requirements.

HEX-LINE multi-celled duct system developed

Introduced Fiber Cable-In-Conduit (CIC)

While Dura-Line does not manufacture the fiber optic cable, we work with industry partners who do and can help customers skip the step of air jetting or pulling in cable by extruding the conduit around fiber optic cable.

Introduced DURATHANE riser rated

Introduced SILICORE super slick permanent lining

In a technology breakthrough, Dura-Line introduced a proprietary lubrication coextruded with conduit products that aided significantly decreasing time spent air jetting fiber. The special formula reduces the friction and greatly improved the distance that could be achieved.

Introduced EVEN-LOAD pull line slack system

First manufacturer of longitudinally ribbed duct

Ribbed duct can be maximized for greater pulling and jetting distances, reducing the coefficient of friction over standard HDPE conduit. The ribs reduce contact which reduces pulling stresses, maximizing distances that can be placed. 

First to develop and offer conduit to the telecom industry, first manufacturer of Fiber optic subduct, and first manufacturer of duct with pre-installed pull line

This is where Dura-Line invented a whole new use for HDPE conduit!

Founded in Middlesboro, KY, manufacturing water and gas products

From humble beginnings a global company has grown!
